The effect of enalapril on mortal and morbid events in patients with hypertension and left ventricular dysfunction.
The objective of this study was to examine the effect of enalapril on morbid and mortal events in patients with left ventricular dysfunction and hypertension using a retrospective analysis of patients with systolic left ventricular dysfunction (ejection fraction < or = 0.35) who participated in the Studies of Left Ventricular Dysfunction (SOLVD). Among the 6797 patients who were randomized to enalapril or placebo, 2652 had history of hypertension, 1508 had systolic blood pressure (SBP) > or = 140 mm Hg, and 985 had diastolic blood pressure (DBP) > or = 90 mm Hg. During average follow-up of 40 months, the rate of hospitalization for congestive heart failure was lower in the enalapril group than the placebo group among patients with history of hypertension (20.6% v 28.3%, P < .001, relative risk [RR] 0.664), and among those with elevated DBP (16.5% v 26.0%, P < .001, RR = 0.574), or SBP (19.5% v 27.7%, P < .001, RR = 0.647) at baseline. These risk ratios were similar to those observed in patients without history of hypertension (RR = 0.647). Also, the decreased rates of mortality, myocardial infarction, stroke, and unstable angina observed in SOLVD were seen, with similar relative risks, in patients with (RR = 0.927, 0.836, 0.979, 0.900, respectively) and without (RR = 0.866, 0.729, 0.775 and 0.743) history of hypertension as well in those with elevated SBP (RR = 0.841, 0.806, 0.707, 0.867) or DBP (RR = 0.791, 0.889, 0.755, 0.872) at baseline.(ABSTRACT TRUNCATED AT 250 WORDS)
