Here is a clear summary of medicines used in the medical management of Congestive Heart Failure (CHF/CCF):
Medical Management of Congestive Heart Failure (CCF)
The four pillars of Guideline-Directed Medical Therapy (GDMT) for HF with reduced EF are:
1. Diuretics (for symptom/fluid relief)
- Furosemide (loop diuretic) - first choice when edema is present
- Thiazides (e.g., hydrochlorothiazide) - in very mild failure
- Spironolactone / Eplerenone (mineralocorticoid receptor antagonists) - reduce morbidity AND mortality in moderate-severe HF
2. ACE Inhibitors / ARBs (reduce mortality in chronic HF)
- ACEIs: Enalapril, Ramipril, Lisinopril - first drug when LV dysfunction present without edema
- ARBs: Losartan, Valsartan - used if ACEI not tolerated
- ARNI (Sacubitril/Valsartan) - reduces symptoms and NT-proBNP; superior to ACEIs in HFrEF
3. Beta-Blockers (reduce mortality)
- Carvedilol, Metoprolol succinate, Bisoprolol
- Reduce HR, BP, and prevent sudden cardiac death
4. SGLT2 Inhibitors (newest pillar)
- Dapagliflozin, Empagliflozin
- Reduce mortality and hospitalizations; also cause natriuresis
5. Other Agents
| Drug | Role |
|---|---|
| Digoxin | Reduces symptoms; rate control in AF; no mortality benefit |
| Ivabradine | Reduces hospitalizations (lowers HR via If channel) |
| Hydralazine + Nitrates | Alternative if ACEIs/ARBs not tolerated (especially in Black patients) |
| Vericiguat | Soluble guanylate cyclase stimulator; for advanced HF |
Acute HF (Decompensated)
- IV Furosemide (diuresis)
- Nitrates (IV nitroglycerine - vasodilation)
- Phosphodiesterase inhibitors (milrinone) - short-term inotropic support
- Positive inotropes (dobutamine) - for low-output states
