Abstract:
Objective To compare the effects of early and long-term treatment with captopril on clinical outcome between elder patients (65-75 years old) and younger patients (< 64 years old) suffering from acute myocardial infarction (AMI). Methods In a randomized trial, 822 patients with a first AMI were treated with captopril at initial dosage of 6.25 mg and adjusted to 25 mg t.i.d according to blood pressure (209 younger patients, 269 elder patients) and conventional treatment (131 younger patients, 213 elder patients). Survival rate of the four groups was calculated with Kaplan-Meier method. Results The survival of treatment group was correlated significantly with age during hospitalization (P=0.0002). Eight patients in younger treatment group and 10 patients in younger control group (3.83% vs 7.63%, P>0.05), 25 patients in elder treatment group and 52 patients in elder control group (9.29% vs 24.41%, relative risk = 0.37, 95% CI 0.29-0.48, P<0.0001) were died. During follow-up period, the survival was however not related to the age (P>0.05), and both the elder and younger patients had better survival (all P<0.01 ) and lower cardiac events (all P<0.01) during captopril treatment. Conclusions Captopril exerts less effect on the younger patients but more effect on the elder patients during hospitalization after AMI. Long-term captopril had no difference between the youngers and the elders in prognosis.
