Abstract
Results from a large multicenter study and from the published literature suggest that
captopril can improve survival in patients with advanced heart failure. The survival
status of 105 patients with moderately severe heart failure who participated in a
multicenter, double-blind comparison of captopril and placebo therapy was ascertained
on an intention-to-treat basis. During the 90-day double-blind portion of this study,
21 percent (11 of 52 patients) of placebo-assigned patients died compared with four
percent (two of 53 patients) of captopril-assigned patients (p <0.01). In addition,
six previously published studies that provided comparative mortality data were identified.
In one of these, the survival rate was reported to be improved in those who received
captopril; in the other five studies, no conclusion could be drawn with respect to
survival since death was an infrequent event within all treatment groups. Mechanisms
by which captopril may improve survival include its favorable effects on hemodynamic
parameters, its association with reduced ventricular ectopic activity, and its inhibitory
effects on the renin-angiotensin and sympathetic nervous systems.
