Long-term captopril therapy in severe refractory congestive heart failure
British Journal of Clinical Pharmacology
|January 1, 1982
Summary
Captopril effectively treats severe congestive heart failure (CHF) in patients refractory to other therapies. This study shows significant improvements in heart failure symptoms and reduced diuretic needs with captopril.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Congestive heart failure (CHF) is a debilitating condition.
- Patients with severe CHF often remain symptomatic despite standard treatments.
Purpose of the Study:
- To evaluate the efficacy of captopril in patients with severe chronic congestive heart failure refractory to existing therapies.
Main Methods:
- Twenty-five patients in New York Heart Association functional class IV received captopril (75-450 mg daily).
- Patients had reduced ejection fraction (shortening fraction ≤18%) and cardiothoracic ratio (60%).
Main Results:
- Ten survivors improved to New York Heart Association class I or II; four improved to class III.
- Diuretic requirements decreased significantly in all survivors.
- While side effects were common, captopril was generally well-tolerated and did not require withdrawal.
Conclusions:
- Captopril demonstrates high efficacy in managing severe congestive heart failure.
- It offers a valuable treatment option for patients unresponsive to conventional therapies.
