[Captopril therapy in chronic congestive heart failure]
Giornale Italiano Di Cardiologia
|January 1, 1983
Summary
Captopril improved cardiac function in patients with chronic congestive heart failure (CCHF) refractory to other treatments. While acute and short-term benefits were observed, long-term effects require further investigation.
Area of Science:
- Cardiology
- Pharmacology
Context:
- 14 patients with chronic congestive heart failure (CCHF) refractory to digitalis and diuretics were studied.
- Patients received increasing doses of captopril (6.25-100 mg) with hemodynamic evaluation.
- Long-term therapy was assessed in 9 patients using clinical, exercise, and imaging methods.
Purpose:
- To evaluate the acute and chronic effects of captopril in patients with refractory CCHF.
- To assess hemodynamic changes and clinical outcomes during captopril treatment.
Summary:
- Acute captopril administration significantly improved hemodynamic parameters, including reduced filling pressures and systemic vascular resistance, with increased cardiac index.
- Short-term (3-6 months) captopril therapy led to improved functional class and exercise tolerance in 7 out of 9 patients.
- However, adverse events including sudden deaths and clinical deterioration were observed during long-term follow-up, necessitating further research.
Impact:
- Captopril demonstrates potential for improving cardiac performance in refractory CCHF patients acutely and in the short term.
- The study highlights the need for controlled trials and extended follow-up to ascertain the long-term safety and efficacy of captopril in CCHF.
