[Drugs prescribed for chronic heart failure. Current data on their effectiveness]

Area of Science:

• Cardiology
• Pharmacology
• Internal Medicine

Background:

• Chronic heart failure (CHF) presents a poor prognosis, necessitating effective therapeutic interventions.
• Pharmacological treatments aim to reduce mortality and enhance the quality of life for CHF patients.

Purpose of the Study:

• To review the efficacy of various drugs in managing chronic heart failure.
• To categorize medications based on their proven impact on mortality and patient outcomes in CHF.

Main Methods:

• Review of existing clinical data and studies on drug efficacy in heart failure.
• Classification of drugs based on evidence for mortality reduction and functional improvement.
• Analysis of indications and contraindications for commonly used heart failure medications.

Main Results:

• Converting enzyme inhibitors (CEI) and certain beta-blockers (metoprolol, bisoprolol, carvedilol) demonstrate proven efficacy in reducing mortality.
• Carvedilol shows significant mortality reduction and improved function, recommended with CEI and diuretics for symptomatic CHF.
• Diuretics, nitrates, and digitalis improve function but lack conclusive mortality data; aldosterone antagonists show preliminary positive effects.

Conclusions:

• CEI and specific beta-blockers are cornerstone therapies for chronic heart failure.
• Drug selection should be guided by proven efficacy in reducing mortality and improving CHF prognosis.
• Further research is needed for drugs with insufficiently proven efficacy, while some have limited indications for specific patient groups.
