title: Further experience with long-term captopril therapy in severe refractory congestive heart failure.
abstract: Fifty patients in severe congestive heart failure (CHF) were treated with captopril (Capoten; Squibb), an oral angiotensin-converting enzyme inhibitor, over a 2-year period (range 3-24 months, mean 8,6 +/- 7,7 months). At entry, all patients were in New York Heart Association (NYHA) functional class IV despite high-dose diuretic and conventional vasodilator therapy. The overall cumulative survival at 6 and 12 months was 64% and 53% respectively. There were 22 deaths (18 during captopril therapy) including 8 sudden deaths. At 2-year follow-up (mean 14,6 +/- 6,9 months), there were 25 survivors on captopril; 18 in NYHA class I or IIS and 7 in class IIM or III. Diuretic requirements were decreased considerably in all. Side-effects were common but transient and in no case did captopril have to be withdrawn. We confirm our earlier conclusion that captopril has long-term beneficial effects and is a highly effective drug in the treatment of patients with CHF refractory to currently accepted therapy. Sudden death despite satisfactory clinical improvement continues to cause concern. Precautions which may reduce or avoid these are briefly discussed.
