| Phenotype | Core move | Pharmacy implication |
|---|---|---|
| HFrEF · LVEF ≤ 40% | ARNI + evidence-based BB + MRA + SGLT2i | Find every missing pillar and every subtarget dose. A low dose of all four usually has more value than maximizing one while leaving gaps. |
| HFimpEF | Continue HFrEF therapy | Normalized EF is not permission to deprescribe. Withdrawal caused frequent relapse in TRED-HF. |
| HFmrEF / HFpEF · LVEF > 40% | SGLT2i + finerenone eGFR ≥60: 20→40 mg qd eGFR 25–59: 10→20 mg qd | Option: finerenone (FDA indication LVEF ≥40%) when baseline K⁺ ≤5.0 and access allow; check K⁺/eGFR at 4 weeks. Spironolactone may be considered in selected higher-EF patients. Eplerenone is not an evidence-equivalent substitute in HFpEF—choose one MRA, never stack. Evidence qualifier: TOPCAT directly tested spironolactone; eplerenone has HFrEF evidence, without equivalent HFpEF outcome evidence. Dapagliflozin and empagliflozin are clinical peers. Avoid BB solely for HFpEF; reserve for AF/rate, ischemia, prior MI, or another indication. |
What is prescribed, filled, taken, skipped, split, or stopped? Include OTCs, supplements, salt substitutes, and prior intolerances.
LVEF/date/trajectory, NYHA, rhythm, QRS/LBBB, ischemic vs nonischemic vs tachyarrhythmia cause, CKD/DM, and recent HF event.
Congestion vs euvolemia; perfusion; orthostasis; current infection, poor intake, AKI, surgery, or pregnancy risk.
BP seated/standing, HR/rhythm, weight/volume, K⁺, SCr/eGFR, Na⁺, Mg²⁺, loop response, and BNP/NT-proBNP trend.
Four classes present? Evidence-based BB? ARNI preferred? Target or maximally tolerated dose? Document the reason for each gap.
Start missing low-BP-effect pillars first when needed; then increase one or more doses using the physiologic constraints below.
Resolve cost/refill/complexity barriers. Favor whole-tablet strengths; do not assume the patient will split pills.
Exact dose/date, hold rules, lab order/date, next contact, patient teach-back, prescriber communication, and escalation owner.
| Current constraint | Usually easiest to add / preserve | Pause, correct, or review first |
|---|---|---|
| Low BP · stable | SGLT2i and MRA usually have little BP effect; keep low doses across classes when possible. | Confirm symptoms/orthostasis; remove non-HF vasodilators; reduce loop if euvolemic. ARNI is usually the strongest BP-lowering pillar; stagger or downshift it if needed. |
| Bradycardia / AV disease | ARNI, MRA, SGLT2i | Review digoxin, amiodarone, diltiazem/verapamil, and conduction disease before increasing BB. |
| Hyperkalemia risk | BB, SGLT2i; ARNI may be retained with close monitoring. | Stop K⁺ supplements/salt substitutes and NSAIDs; review MRA/RAASi dose and consider a K⁺ binder. |
| Congested · stable | MRA + SGLT2i are congestion-friendly; use a loop for residual clinical volume. | Do not increase BB until congestion improves. Once euvolemic, work toward the lowest effective loop dose or off with a monitoring plan. |
| Stable · BP/HR/K allow | Start missing classes now; increase toward target every 1–2 weeks. | Do not wait for one drug to reach target before adding the next class. |
| Correct therapy | Meaningful intensity | Safe feedback loop | Sustainable execution |
|---|---|---|---|
| Right class and agent; the patient is actually taking it. No duplicate RAAS/MRA or obsolete list entry. | Target or maximally tolerated; an objective limiter and revisit plan are documented for every subtarget dose. | Current vitals/labs; next lab/contact is booked and a named clinician owns the result and next change. | Affordable and in hand; the patient can teach back dose, purpose, hold rules, refill route, and escalation plan. |
| Not yet implemented: “recommended,” prescription pending, unaffordable at the pharmacy, patient unsure how to take it, safety lab not ordered, or “intolerant” without the symptom/mechanism and attempted workaround. | |||
| Medication history | Physiology | Laboratory | Execution |
|---|---|---|---|
| ACEi timing · angioedema · BB identity · duplicate RAAS/MRA · OTC NSAID/K⁺ · pregnancy risk | Congestion · perfusion · seated/standing BP · HR/rhythm · oral intake · diuretic need | K⁺ · SCr/eGFR · Na⁺ · Mg²⁺; recent trend matters more than one isolated value | Coverage/cost confirmed · prescription in hand · counseling/hold rules · lab and follow-up already booked |
| Medication order | Safety orders | Patient plan | Access & ownership |
|---|---|---|---|
| Drug, whole-tablet strength when feasible, exact sig, start date, quantity/refills; explicitly discontinue the replaced/duplicate order. | Baseline BP/HR/K⁺/SCr; lab order and due date; drug-specific hold rules; named result reviewer. | Plain-language schedule and purpose; sick-day/procedure instructions; side-effect and escalation plan; teach-back. | Formulary/cost/stock checked; pickup/delivery confirmed; refill due date; next contact and titration owner. |
| Switch cleanly: ACEi → ARNI requires a documented 36-hour gap; ARB → ARNI has no washout but must not overlap; discontinue the old formulation when changing BB or MRA; when adding SGLT2i, reassess volume and whether the loop dose needs adjustment. | |||
| Agent | Start / renal boundary | Hard interaction or monitoring rule |
|---|---|---|
| Sacubitril/valsartan | Usual 49/51 mg BID; start 24/26 mg BID with no/low prior ACEi/ARB, eGFR <30, or Child-Pugh B; double every 2–4 weeks as tolerated. | 36-hour ACEi gap; no ACEi/ARB overlap; avoid prior ACEi/ARB angioedema and pregnancy. K⁺ drugs, NSAIDs, lithium, renal-artery stenosis, and volume depletion require deliberate review. |
| Eplerenone / spironolactone | HFrEF guideline gate: eGFR >30 and K⁺ <5.0. Eplerenone label: 25→50 mg qd; check K⁺ baseline, within 1 week, at 1 month, then periodically. | Eplerenone: CrCl ≤30 and strong CYP3A inhibitors are contraindications; with a moderate CYP3A inhibitor, post-MI HFrEF dose should not exceed 25 mg qd. Review TMP-SMX, NSAIDs, K⁺/salt substitutes, ACEi/ARB/ARNI. |
| Finerenone · LVEF ≥40% | Baseline K⁺ ≤5.0. eGFR ≥60: 20→40 mg qd; eGFR 25–59: 10→20 mg qd; do not initiate eGFR <25. Recheck K⁺/eGFR at 4 weeks. | Strong CYP3A inhibitors and adrenal insufficiency are contraindications; avoid grapefruit and strong/moderate inducers. Moderate/weak inhibitors or K⁺-raising drugs require closer K⁺ surveillance. Use one MRA only. |
| Dapagliflozin | 10 mg qd. For HF/CKD, label permits initiation at eGFR ≥25; if eGFR later falls below 25, therapy may continue for cardiorenal benefit. | Assess renal function and volume first. Hold ≥3 days before major surgery/prolonged fasting; resume only when clinically stable and oral intake has resumed. |
| Empagliflozin | 10 mg qd. HF trials enrolled eGFR ≥20; label notes no HF/CKD trial enrollment below 20 or on dialysis—route initiation below that evidence boundary. | Assess renal function and volume first. Same ≥3-day procedure/fasting hold and stable/eating restart rule; evaluate ketoacidosis regardless of glucose. |
| Current K⁺ | Dose action | Restart / renal qualifier |
|---|---|---|
| <5.0 mmol/L | Advance 10→20 mg; at 20 mg, maintain if initial eGFR <60, otherwise advance to 40 mg; maintain 40 mg. | If eGFR has fallen >30% from the prior value, maintain rather than increase. |
| 5.0 to <5.5 | Maintain current dose. | Recheck based on trajectory and interacting medicines. |
| 5.5 to <6.0 | At 40 mg: reduce to 20 mg. At 20 mg: reduce to 10 mg. At 10 mg: withhold. | After a 10-mg hold, restart 10 mg when K⁺ <5.5. |
| ≥6.0 | Withhold at any dose and manage promptly through the urgent hyperkalemia assessment. | Restart 10 mg when K⁺ <5.5; if repeated measurements remain ≥5.5, wait until K⁺ <5.0. |
| Trigger | Risk | Pharmacist action |
|---|---|---|
| TMP-SMX · K⁺ · salt substitute · NSAID | Hyperkalemia, AKI, sodium/fluid retention; may erase RAASi/MRA/diuretic benefit. | Remove/substitute when feasible; repeat K⁺/SCr promptly if exposure is necessary. |
| Clarithromycin · itraconazole/ketoconazole · ritonavir/cobicistat | Strong CYP3A inhibition can markedly raise eplerenone/finerenone exposure. | Do not coadminister with eplerenone or finerenone; choose an alternative and document the interaction. |
| Diltiazem · verapamil · fluconazole | Moderate CYP3A effect plus rate slowing; non-DHP CCBs can worsen HFrEF. | Verify indication; apply the eplerenone cap/finerenone K⁺ surveillance and reassess BB/ivabradine bradycardia risk. |
| Loop diuretic · poor intake · insulin reduction | Volume depletion with SGLT2i; large insulin reduction/fasting increases ketoacidosis risk. | Correct volume depletion, individualize loop change, avoid reflex insulin withdrawal, and give explicit ketone/illness instructions. |
| Change | First planned check | What closes the loop |
|---|---|---|
| ARNI / ARB | BP/orthostasis and K⁺/SCr in about 1–2 weeks; sooner for low BP, CKD, frailty, volume loss, or interacting drugs. | Result reviewed by a named clinician; symptoms and home BP support the next dose, a slower step, or correction of a reversible limiter. |
| Eplerenone / spironolactone | K⁺/SCr in 3–7 days, again near 4 weeks, after every dose/clinical change, then periodically; intensify for CKD or K⁺-raising exposure. | Act on the trend—not an isolated value—and remove contributors before permanently abandoning a prognostic pillar. |
| Finerenone | K⁺/eGFR at 4 weeks after initiation, restart, or dose increase, then periodically and after relevant interaction/illness. | Apply the labeled K⁺ algorithm above and document the next test when maintaining, reducing, withholding, or restarting. |
| SGLT2 inhibitor | No titration. Arrange an early volume/renal touchpoint—often 1–2 weeks when older, CKD, low BP, on a loop, or recently congested. | Weight/volume, intake, symptoms, renal trend when indicated, genital/urinary symptoms, and a clear sick-day/procedure restart owner. |
| Beta-blocker | HR/rhythm, BP/orthostasis, weight, fatigue, and congestion in about 2 weeks before the next increase. | Advance toward the trial dose only if rhythm, perfusion, and volume permit; do not chase dose through bradycardia or recurrent congestion. |
PARADIGM-HF also found all-cause death ↓16%, first HF hospitalization ↓21%, and less symptom/physical limitation burden.
Clinical value: prognostic RAAS/neprilysin therapy with remodeling and natriuretic-peptide effects; it is more than a BP drug.
AE rates · ARNI vs enalapril: symptomatic hypotension 14.0% vs 9.2%; creatinine ≥2.5 mg/dL 3.3% vs 4.5%; cough 11.3% vs 14.3%.
Say: “This helps you live longer and lowers the chance that heart failure puts you in the hospital.” Limiter: usually the strongest BP-lowering pillar.
MERIT-HF found sudden death ↓41% and death from worsening HF ↓49%. In severe HFrEF, carvedilol reduced death/CV hospitalization by 27%.
Clinical value: blunts harmful adrenergic drive, stabilizes rhythm, and supports reverse remodeling; benefit develops over weeks to months.
Withdrawal-causing AE · metoprolol vs placebo: bradycardia 0.8% vs 0.2%; hypotension 0.6% vs 0.2%; withdrawal for any AE 9.8% vs 11.7%.
Say: “This protects against dangerous rhythms and helps the heart recover.” Titrate by HR/rhythm; transient fatigue is not proof of no benefit.
Symptoms and worsening-HF admission also improved with spironolactone. In milder HFrEF, EMPHASIS-HF CV death/HF hospitalization was 18.3% vs 25.9% over median 21 months (HR 0.63).
Clinical value: blocks aldosterone-driven sodium retention and fibrosis with little BP effect; often helps preserve a four-pillar regimen when BP is tight.
AE rates: EMPHASIS-HF eplerenone vs placebo—K⁺ >5.5 11.8% vs 7.2%; AE discontinuation 13.8% vs 16.2%. RALES male gynecomastia/breast pain, spironolactone vs placebo: 10% vs 1%.
Say: “This blocks a hormone that makes the heart scar and retain salt.” Favor eplerenone when endocrine adverse effects are a concern; monitor K⁺/kidney function.
Worsening-HF events fell 30%; CV death fell 18%; benefit was present with or without diabetes. Empagliflozin provides a concordant HFrEF class effect.
Clinical value: early HF-event reduction, kidney/volume support, once-daily dosing, and no titration; reassess whether the loop remains necessary.
Selected AE · dapagliflozin vs placebo: volume depletion 7.5% vs 6.8%; renal AE 6.5% vs 7.2%; AE discontinuation 4.7% vs 4.9%; definite/probable DKA 0.1% vs 0.
Say: “This protects the heart and kidneys and lowers HF visits—even without diabetes.” Jardiance and Farxiga are clinical peers.
| Therapy / phenotype | What the trial showed | What to tell the patient and team |
|---|---|---|
| SGLT2i · LVEF >40% | DELIVER primary outcome HR 0.82, driven by worsening HF (HR 0.79); CV death was not significantly lower. Empagliflozin showed a concordant HF-event benefit. | Benefit is mainly fewer worsening-HF events, plus symptom and kidney/volume advantages—not a proven mortality claim. Benefit does not require diabetes. |
| Finerenone · LVEF ≥40% | FINEARTS-HF reduced total worsening-HF/CV-death events by 16% (RR 0.84), driven by worsening-HF events; CV death was not significantly lower. Investigator-reported hyperkalemia was 9.7% vs 4.2%; worsening-renal-function AEs 18% vs 12%. | Benefit is fewer recurrent/worsening HF events. Prefer when K⁺/eGFR/access allow. TOPCAT directly tested spironolactone; eplerenone lacks equivalent HFpEF outcome evidence. Use only one MRA. |
| Beta-blocker · HFpEF | No established HFpEF-specific prognostic indication. | Avoid solely for HFpEF. Use for AF/rate control, ischemia, prior MI, or another independent indication; excess rate slowing may worsen exercise tolerance. |
| Drug | Primary benefit | Boundary / outpatient use |
|---|---|---|
| Loop diuretic | Fastest congestion and symptom relief | No proven survival benefit. Once euvolemic and MRA/SGLT2i are established, taper toward the lowest effective dose or off with a rescue plan. |
| Ivabradine | Fewer HF admissions; SHIFT primary HR 0.82, driven mainly by HF hospitalization (HR 0.74). | Sinus HFrEF with HR ≥70 despite carvedilol 50 mg BID or metoprolol XL 200 mg daily / maximally tolerated evidence-based BB; not a BB substitute. |
| Vericiguat | Modest post-worsening-HF event reduction; primary HR 0.90, without significant CV-death reduction. | Possible after recent worsening HFrEF, but lower priority than completing foundational therapy; limited quality-of-life signal. |
| ARB / ACEi fallback | Retains RAAS prognostic therapy when ARNI is not feasible | Use ARNI when feasible, otherwise ACEi or ARB according to indication and tolerance. Do not overlap. Observe the ACEi washout before ARNI. |
Reconcile; cause/EF/QRS; BP/HR/weight/volume; K⁺/SCr/eGFR; BNP or NT-proBNP. Start missing classes; book labs/contact.
Risk-based lab check after MRA/RAASi for prior AKI/hyperK, frailty, CKD, major diuretic change, poor intake, or recent acute care.
Symptoms, orthostasis, HR/rhythm, weight/volume, adherence/access, K⁺/SCr. Add a class or increase a dose if stable.
Repeat visits, calls, or portal contacts until all four classes are present and doses reach target or a documented maximum tolerated level.
Check BNP/NT-proBNP regularly and with meaningful status change; repeat safety labs after illness, volume change, interaction, or intolerance.
| Domain | Ask / measure | Translate into action |
|---|---|---|
| Symptoms / function | Dyspnea, orthopnea/PND, edema, bendopnea, dizziness/syncope, fatigue, exercise tolerance, NYHA class | New congestion or low-output symptoms are not a routine titration visit; route to clinical assessment. |
| Home data | Daily weights/trend, BP with technique and symptoms, HR/rhythm alerts; verify device and cuff size | Use trends, not one number. Repeat orthostatic vitals when dizziness or falls are present. |
| Volume / perfusion | Diuretic response, edema, JVP if trained, urine output, thirst/poor intake, coolness/confusion | Distinguish congestion-driven renal change from overdiuresis. If euvolemic, document the next loop reduction/off-trial and rescue trigger. |
| Medication use | Exact dose/time; missed doses; last fill; tablet splitting; side effects; OTCs/supplements; sick-day holds | Fix the barrier. Prefer a whole-tablet plan the patient will actually take tomorrow. |
| Labs + peptides | K⁺, SCr/eGFR, Na⁺, Mg²⁺ plus same-assay BNP/NT-proBNP trajectory; align with volume/illness changes | Trend + clinical context determine action. Assign who reviews the result and who calls the patient. |
| Access | Copay, PA, supply on hand, refill timing, delivery/transport, pharmacy alignment, caregiver support | Do not count a pillar as “started” until the patient can obtain and correctly take it. |
| Signal | Usually acceptable / first response | Escalate or modify |
|---|---|---|
| K⁺ < 5.0 | Eligible for MRA if eGFR >30; review supplement/salt-substitute use. | Recheck on schedule after start/dose change. |
| K⁺ 5.0–5.5 | Repeat/confirm; remove K⁺/NSAIDs; review diet, acidosis, constipation, AKI, and interacting drugs. | Individualize RAASi/MRA change with prescriber; increase surveillance. A binder can support continued therapy in selected patients. |
| K⁺ > 5.5 | Do not ignore or wait for a routine visit; assess symptoms, renal trajectory, hemolysis, and ECG need. | Prompt prescriber/urgent hyperkalemia assessment; MRA reduction/hold is usually required if K⁺ cannot be maintained below 5.5. |
| SCr rise / eGFR dip | A modest early hemodynamic change can occur. Reassess volume, BP, NSAIDs, infection, intake, and diuretic intensity. | Progressive or roughly ≥30% creatinine rise, oliguria, hypotension, or electrolyte change requires prompt clinical review. |
| Low BP | Asymptomatic low BP alone is not automatic failure. Repeat correctly; check orthostasis/volume; remove non-HF BP drugs and excess loop first. | ARNI is usually the strongest BP lever; downshift/stagger it before abandoning MRA/SGLT2i. Symptoms, syncope, or hypoperfusion → route. |
| Low HR | BB is an HR/rhythm intervention. Confirm rhythm and remove nonessential rate-slowers before sacrificing evidence-based BB. | Symptoms, HR <50, or new/high-grade block → prescriber/ECG review before the next BB dose change. |
Higher-risk patients often receive less therapy. Risk is the reason to build a monitored pathway, not to accept inertia.
Benefits emerge within days to weeks. Start pillars simultaneously or in rapid sequence; do not maximize serially.
The hospital-to-clinic handoff is an implementation opportunity. Leave with medications, labs, and visits already booked.
Rapid care is not unmonitored care. Use repeated vitals, congestion assessment, K⁺/eGFR, and NT-proBNP.
Weigh the known risk of delaying or omitting proven therapy alongside the potential adverse effect of starting it.
| Time point | Required assessment | Dose action |
|---|---|---|
| Entry · ≤2 days before discharge | Clinical stability and improving congestion; all prior-24-h SBP ≥100, HR ≥60, K⁺ ≤5.0; NT-proBNP decreased >10% from screening | Aim for ≥50% of optimal dose of RASi/ARNI, BB, and MRA when eligible; changes may occur the same day or across the final 2 days. |
| Week 1 · safety | Symptoms/NYHA, full HF exam, BP/HR/weight/congestion; K⁺, kidney function, Na⁺, and NT-proBNP; adherence/access | Confirm tolerance and apply the gates below. If a change is delayed, define the correction and add a safety visit 1 week later. |
| Week 2 · optimize | Repeat the complete safety dataset before changing therapy | Aim for 100% guideline target or the documented maximum tolerated dose. In the secondary analysis, >90% reached at least medium (≥50%) dosing by week 2; higher achieved doses tracked with better outcomes. |
| Week 3 · safety | Repeat exam, vitals, congestion, K⁺/kidney function/Na⁺, NT-proBNP, adverse effects and medication use | Maintain safe full doses; restart or advance any temporarily delayed class when the limiting signal resolves. |
| Week 6 · consolidate | Same dataset plus functional status, access/refills, and the residual loop-diuretic requirement | Close remaining gaps; document target vs maximum tolerated dose, the reason for every ceiling, and the maintenance owner. |
| Gate | Do not advance when | Immediate response |
|---|---|---|
| RASi / ARNI and MRA | SBP <95 mmHg, K⁺ >5.0 mmol/L, or eGFR <30 mL/min/1.73 m² | Hold that titration step; correct volume/interactions, repeat the measurement, and keep unaffected pillars whenever safe. |
| Beta-blocker | SBP <95 mmHg or HR <55 bpm; also do not increase BB with an early NT-proBNP rise | Reassess rhythm, perfusion and congestion. Remember: BB is the HR/rhythm lever and should not be increased through active congestion. |
| NT-proBNP rise | >10% above the pre-discharge/randomization value | Delay further titration 1 week; do not increase BB. Reassess for congestion and increase diuretic if clinically congested; repeat the full safety dataset. |
| Clinical deterioration | New/worsening congestion, symptomatic hypotension/bradycardia, hypoperfusion, AKI, or unsafe electrolyte change | Exit protocol titration; route to same-day HF/prescriber assessment or emergency care when severe. |
| Contemporary HFrEF | Physiology | Congestion | Execution |
|---|---|---|---|
| STRONG-HF did not protocol-titrate SGLT2i. Add dapagliflozin/empagliflozin early when eligible; no dose titration. | ARNI is usually the BP lever; BB is the HR/rhythm lever. Preserve MRA/SGLT2i when BP is the isolated constraint. | Do not increase BB through congestion. After euvolemia on MRA/SGLT2i, taper the loop toward the lowest effective dose/off. | Every visit ends with the exact change, same-day orders, lab date, next visit, patient teach-back, and one named result owner. |
| Problem | Check first | Preserve benefit / practical move |
|---|---|---|
| Symptomatic low BP | Orthostatics; congestion vs dry; diarrhea/poor intake; alpha-blocker, nitrate, CCB, other vasodilator; excessive loop dose | Remove non-HF BP drugs; if euvolemic, trim loop. ARNI is usually the strongest BP lever; stagger/downshift it while preserving MRA/SGLT2i. |
| Bradycardia / fatigue | ECG/rhythm; digoxin, amiodarone, diltiazem/verapamil; hypothyroidism; sleep apnea; volume/perfusion | BB titration is HR-directed. Remove nonessential rate-slowers first; reduce BB only for symptoms/unsafe rhythm. Avoid BB solely for HFpEF. |
| Creatinine rise | Congestion, diuretic response, BP, poor intake, infection, NSAID, contrast, urinary obstruction, SGLT2i timing | Treat the cause. Do not equate every stable early eGFR dip with kidney injury; progressive rise, oliguria, hypotension, or electrolyte change needs prompt review. |
| Hyperkalemia | Repeat nonhemolyzed sample; K⁺ supplement/salt substitute; NSAID; TMP-SMX; AKI; diet; constipation/acidosis | Remove contributors, optimize diuretic if congested, adjust MRA/RAASi with close labs; selected patients may use patiromer/SZC to maintain therapy. |
| Congestion / weight gain | Adherence, sodium load, NSAID/steroid/TZD, renal change, arrhythmia, ischemia, infection; loop timing/bioavailability | Decongest first; do not increase BB during active congestion. Once euvolemic on MRA/SGLT2i, taper the loop toward lowest effective dose/off. |
| RAAS intolerance | Cough vs pulmonary congestion; true angioedema; volume/BP; ACEi-to-ARNI timing | Use ARNI when feasible. Otherwise choose ACEi or ARB by indication and tolerance. Angioedema → emergency assessment and permanent culprit-class documentation. |
| MRA endocrine AE | Gynecomastia, breast pain, sexual dysfunction; dose and renal function | Consider eplerenone for endocrine tolerability when cost/access permit. If on spironolactone, switch within class rather than drop the MRA. |
| SGLT2i symptoms | Genital infection, volume depletion, poor intake, surgery, insulin reduction, nausea/abdominal pain/dyspnea | Treat uncomplicated genital infection without automatic permanent discontinuation. Suspected euglycemic DKA → stop, check ketones/anion gap, urgent evaluation. |
| Pattern | Trigger | Practice move |
|---|---|---|
| Persistent sinus tachycardia | LVEF ≤35% and resting HR ≥70 despite target/max-tolerated evidence-based BB | Verify sinus rhythm, adherence, thyroid/anemia/infection/volume drivers, and a true BB ceiling; then use the ivabradine pathway on P.8. |
| Recent worsening HFrEF | HF hospitalization or IV diuretic despite the four pillars | Reassess congestion, adherence, ischemia/rhythm, iron deficiency, device candidacy, and advanced-HF trajectory; P.8 lists lower-priority pharmacologic add-ons. |
| LBBB / dyssynchrony CM | Wide LBBB/QRS with persistently low EF despite GDMT | Medication response may be limited because the mechanism is electrical. Do not keep turning medication knobs while delaying CRT/device evaluation when criteria are met. |
| Tachyarrhythmia-induced CM | AF/flutter/SVT, mean HR >100, or high ectopy burden plausibly driving EF | Often has the greatest recovery potential: prioritize rhythm/rate or burden control while maintaining GDMT; confirm recovery on follow-up imaging. |
| Ischemic / scar CM | Prior MI, obstructive CAD, scar pattern, regional dysfunction | EF is often more fixed than tachyarrhythmia CM. Ensure the ischemia/revascularization, ICD/CRT, and secondary-prevention pathways are addressed; do not promise normalization from dose escalation alone. |
| Medication / product | Why it matters in HF | Pharmacy action |
|---|---|---|
| NSAIDs · incl. OTC | Fluid/sodium retention, BP rise, kidney injury, hyperkalemia; can blunt diuretic/RAASi effect. | Stop/avoid when possible; recommend an indication-appropriate alternative and document counseling. |
| Thiazolidinediones | Fluid retention; may precipitate/worsen symptomatic HF. | Route to diabetes/prescriber team for an alternative. |
| Diltiazem / verapamil in HFrEF | Negative inotropy; no HFrEF outcome benefit. | Verify indication; do not stop abruptly if used for rate control, but route for a safer strategy. |
| K⁺ supplement / salt substitute | Raises hyperkalemia risk with ARNI/ACEi/ARB/MRA. | Keep only with a clear indication and monitoring plan; ask specifically about “low-sodium” salt. |
| OTC decongestant / stimulant | May raise BP/HR or trigger arrhythmia. | Check labels and suggest a symptom-specific alternative; reinforce when to seek care. |
| Option | Who / dose | What it buys | Key risk / action |
|---|---|---|---|
| Hydralazine / isosorbide dinitrate | Self-identified Black patients with NYHA III–IV HFrEF on optimal therapy: fixed 20/37.5 mg TID→40/75 mg TID. Also specialist-consider if ARNI/ARB/ACEi cannot be used; evidence is weaker for that route. | A-HeFT, add-on vs placebo: death 6.2% vs 10.2%; first HF hospitalization 16.4% vs 24.4% at mean 12 months. | Headache 47.5% vs 19.2%; dizziness 29.3% vs 12.3%. TID burden, BP, lupus-like syndrome; nitrates + PDE5 inhibitor are contraindicated. |
| Ivabradine | Stable symptomatic HFrEF, LVEF ≤35%, sinus rhythm HR ≥70 after maximally tolerated evidence-based BB. 5 mg BID with food (2.5 mg if conduction/brady risk) → HR 50–60; max 7.5 mg BID. | SHIFT: CV death/HF admission 24% vs 29% over median 22.9 months, driven mainly by HF admission—not a mortality claim. | Symptomatic bradycardia 5% vs 1%; phosphenes 3% vs 1%. Monitor AF/rhythm; avoid strong/moderate CYP3A inhibitors and pacemaker dependence. |
| Vericiguat | Symptomatic chronic HF, EF <45%, after HF hospitalization or outpatient IV diuretic. Current label: 5 mg qd with food→10 mg, doubling about every 2 weeks; use 2.5 mg start if symptomatic-hypotension risk. | VICTORIA: CV death/first HF hospitalization 35.5% vs 38.5% over median 10.8 months (HR 0.90); CV death not significantly lower and no meaningful KCCQ advantage. | Consider after foundational therapy. Hypotension 16% vs 15%; anemia 10% vs 7%. Pregnancy contraindicated; no other sGC stimulator; PDE5 inhibitor not recommended. |
| Digoxin | Selected symptomatic HFrEF despite GDMT or when GDMT is limited. Usually 0.125 mg qd or less in older/CKD patients; individualize to serum 0.5–<0.9 ng/mL. | DIG: HF hospitalization 26.8% vs 34.7% over mean 37 months; mortality neutral (34.8% vs 35.1%). | Suspected-toxicity hospitalization 2.0% vs 0.9%. Renal dosing; K⁺/Mg²⁺, level timing, brady/AV block, nausea/confusion/vision; many P-gp/rate-slowing interactions. |
| Option | Before the order | Booked follow-up |
|---|---|---|
| Hydralazine / ISDN | Seated/standing BP, nitrate/PDE5-inhibitor interaction, headache/dizziness history, and ability to execute TID dosing. | BP, orthostasis, headache, dizziness, adherence, and symptoms; investigate fever, arthralgia, or other lupus-like features. |
| Ivabradine | Document sinus rhythm, resting HR ≥70, LVEF ≤35%, maximally tolerated evidence-based BB, ECG/conduction status, and CYP3A interactions. | HR/rhythm and tolerance after about 2 weeks; adjust toward HR 50–60 and assess bradycardia, AF, and luminous visual symptoms. |
| Vericiguat | Recent worsening-HF event, BP/symptoms, hemoglobin/anemia context, interacting sGC/PDE5 therapy, and pregnancy status when relevant. | BP, symptoms, and anemia surveillance with each approximately 2-week dose step; confirm food administration and adherence. |
| Digoxin | eGFR, K⁺, Mg²⁺, rhythm/conduction, age/weight, and P-gp or rate-slowing interactions; choose a renal-appropriate dose. | Renal/electrolyte trend and a correctly timed level after steady state, dose/interaction change, renal change, or suspected toxicity—not as an isolated number. |
| IV iron | CBC, ferritin, TSAT, cause of deficiency, blood-loss risk, prior infusion reaction, and product-specific eligibility. | Product-specific infusion surveillance and a defined repletion/iron-index reassessment; continue investigation of the cause. |
| Option | Signal and immediate pharmacist response |
|---|---|
| Hydralazine / ISDN | Syncope/symptomatic hypotension, a nitrate–PDE5 interaction, or fever/arthralgia/serositis/rash suggesting a lupus-like syndrome → hold the suspected drug when clinically appropriate and contact the prescriber urgently; document any interaction exposure. |
| Ivabradine | Resting HR <50 with symptoms, new AF, high-grade conduction disease, or uncertainty about pacemaker dependence → ECG/rhythm review and prescriber contact before the next dose or titration. |
| Vericiguat | Symptomatic hypotension, suspected pregnancy, concurrent sGC stimulator, or worsening anemia symptoms → pause escalation and route promptly; do not use dose escalation to compensate for unresolved congestion. |
| Digoxin | New bradycardia/AV block/arrhythmia, nausea/vomiting, confusion, color/visual change, acute renal decline, or low K⁺/Mg²⁺ → hold and obtain a clinical assessment with ECG, chemistry, renal function, and a correctly timed level. |
| Pattern | Do now | Practice lens |
|---|---|---|
| LBBB / wide QRS + low EF | Confirm QRS morphology/duration, rhythm, pacing burden, EF trajectory, symptoms, and GDMT duration; route for CRT/device evaluation when criteria may be met. | Dyssynchrony cardiomyopathy may respond incompletely to drug escalation; do not delay a mechanism-matched therapy. |
| Potential tachyarrhythmia CM | Quantify AF/flutter/SVT or ectopy burden; prioritize rhythm/rate/burden control with EP/cardiology while preserving tolerated GDMT. | Recovery potential is often greater than in fixed ischemic/scar cardiomyopathy; reassess EF after the culprit is controlled. |
| Ischemic / scar phenotype | Clarify coronary anatomy, prior infarct/revascularization, ischemic symptoms, and relevant imaging; manage ischemia and secondary prevention with cardiology. | Scar burden may constrain EF recovery. Set realistic goals while preserving the event and symptom benefits of GDMT. |
| Advanced-HF trajectory | Recurrent HF care, escalating loop need, hyponatremia, end-organ decline, low BP limiting therapy, cachexia, inotrope need, or intolerance of multiple pillars → advanced-HF review. | Referral while ambulatory preserves options; do not wait for shock, irreversible organ dysfunction, or repeated crisis care. |
| Referral | Include in the handoff |
|---|---|
| Device / CRT | 12-lead ECG with QRS morphology/duration; rhythm and pacing burden; current/prior LVEF with dates; NYHA symptoms; GDMT agents, doses, duration, and objective limiters; relevant coronary history. |
| EP / arrhythmia-CM | ECGs and ambulatory-monitor burden/rates; timing versus EF decline; prior rhythm/rate therapy and response; K⁺/Mg²⁺/TSH; symptoms/syncope; anticoagulation status when AF/flutter is present. |
| Advanced HF | HF ED/hospital/IV-diuretic events; loop-dose trajectory; BP and GDMT intolerance; Na⁺, renal/liver trend, NT-proBNP; weight/cachexia; functional decline; right-sided symptoms; goals, support, and major comorbidities. |
| Iron / cause workup | CBC indices, ferritin, TSAT and dates; bleeding/GI/renal context; antithrombotics; prior oral/IV iron and reactions; selected formulation and ownership of post-repletion testing. |
| Lane | Examples | Action |
|---|---|---|
| Planned specialty review | Persistent low EF with LBBB/wide QRS; measured arrhythmia burden; iron deficiency; uncertain recovery mechanism; stable advanced-HF risk signal. | Place the decision-ready referral, complete prerequisite testing, and assign the follow-through milestone. |
| Same-day HF / prescriber | Rapidly rising weight or loop need, new/worsening congestion, symptomatic hypotension/bradycardia, syncope/presyncope, rapidly changing K⁺/SCr/Na⁺, or inability to obtain essential therapy. | Stop protocol titration; contact the responsible clinician now for examination, testing, and disposition. |
| Emergency evaluation | Severe resting dyspnea/hypoxia, chest pain/possible ACS, syncope with instability, confusion/hypoperfusion, angioedema, or suspected ketoacidosis. | Use the emergency response system; do not manage by portal message or a routine future appointment. |
| EF milestone | Rhythm milestone | Referral milestone | Iron milestone |
|---|---|---|---|
| Repeat imaging date and the decision it will trigger are documented. | Burden is measured; control strategy and post-control reassessment are assigned. | Order accepted, urgency clear, appointment/owner known, and required testing completed. | Repletion completed; cause addressed; CBC/ferritin/TSAT recheck booked and reviewed. |
| Barrier | Useful question | Practical fix |
|---|---|---|
| “What did the pharmacy say the price would be? Which prescription did you leave behind?” | Real-time formulary check; generic/covered alternative; PA; copay/PAP; 30- vs 90-day math; confirm pickup/delivery and next refill. | |
| “Walk me through yesterday from waking to bedtime. Which pills are you cutting or skipping?” | Prefer whole-tablet strengths; do not build the plan around half tablets unless the patient accepts and can do it. Align timing; synchronize fills; pillbox/blister pack; written purpose map. | |
| “Which symptom worries you, and what happened after which pill?” | Name likely culprit; validate; explain benefit/time course; adjust timing/dose or switch within class; give a rescue/escalation plan; re-challenge deliberately. | |
| “What do you think these medicines are doing for you?” | Link each drug to the patient’s goal: stay home, breathe/walk farther, protect kidney/heart, be present for family. Explain prevention despite feeling well. | |
| “How confident are you that you could show someone else exactly how to take these?” | Plain language, large-print visual schedule, teach-back, interpreter, caregiver, pharmacy packaging; remove contradictory lists. | |
| “What usually prevents the refill or follow-up from happening?” | Delivery/transport, automatic refill, lab location/hours, portal/phone route, caregiver authorization, single accountable pharmacy/HF contact. |
| ARNI | “Relaxes the circulation and changes the heart’s stress signals to help you live longer and stay out of the hospital.” |
| Beta-blocker | “Protects the heart from excess stress and helps it work more efficiently over time.” |
| MRA | “Blocks a hormone that drives salt retention and heart scarring; it also helps the congestion plan.” |
| SGLT2i | “Protects the heart and kidneys, lowers HF events, and may reduce the fluid-pill requirement—even without diabetes.” |
| Loop diuretic | “Relieves extra fluid and symptoms; our goal is the lowest dose you need, sometimes none.” |
