Diuretics (drugs which increase urine output), morphine and oxygen are often used to treat patients who have to come to emergency ward with acute heart failure. But what are newer drugs useful for management of patients with acute heart failure? I am looking for names of such agents, each with a one line summary of their current status for this indication. Thanks for your responses.
I checked myself and found following agents are useful:
- diuretics (for example frusemide, torsemide): to reduce fluid accumulation in lungs and other parts of body. Other agents such as thiazide and metolazone may be added if response is not adequate.
- morphine: reduces anxiety, distress and diverts blood away from lungs by dilating peripheral blood vessels, especially veins.
- oxygen: should be given only if hypoxia is there; otherwise it can cause vasoconstriction and may be deleterious.
- vasodiators: e.g. nitroglycerin (or isosorbide dinitrate), nitroprusside, nesiritide. Used if blood pressure is not low.
- inotropes: e.g. dobutamine, milrinone, levosimendan. Used if blood pressure is low.
- vasopressors: e.g. dopamine, norepinephrine: only if blood pressure is low and not responding to inotropes.
- low molecular weight heparin e.g. enoxaparin: to reduce risk of deep vein thrombosis
As patient stabilizes, agents known to be useful in long term treatment of chronic heart failure are added:
- ACE (angiotensin converting enzyme) inhibitors (e.g. enalapril, ramipril) or ARBs (angiotensin receptor blockers) (e.g. losartan, telmisartan)
- Aldosterone antagonist: e.g. spironolactone, eplerenone
- Digoxin: especially useful if patients with atrial fibrillation
- Ivabradine: useful in a subset of patients with chronic heart failure.
- Valsartan/sacubitril combination: recently approved; shown to have better response than ACE-inhibitors in a large study.
These agents have been shown to provide survival benefit in long term to patients with heart failure.
