BACKGROUND: Stroke is the third cause of death in older people living in Western countries. We tested the hypothesis that angiotensin-converting enzyme inhibitors (A-I) might affect short-term (30 day) mortality in older persons with severe acute ischemic stroke. METHODS: We analyzed data from a retrospective study including 475 consecutive older patients hospitalized for acute ischemic stroke. Mean age was 78.4 +/- 9.2 years; 58.2% were female. Stroke type was classified according to the Oxford Community Stroke Project (OCSP). RESULTS: Mortality rate was 28%. Thirty-two percent of patients were treated with A-I; mortality was 16.5% in patients treated compared with 33.3% in those not treated (chi(2) p =.001). The odds ratio for mortality in treated patients was: 0.47 (0.25-0.89) after full adjustment (age, sex, mean diastolic and systolic blood pressure, previous stroke and/or transient ischemic attack, congestive heart failure, atrial fibrillation, diabetes, hypertension, coronary heart disease, and previous treatment with A-I); 0.29 (0.09-0.89) in patients with altered level of consciousness after full adjustment; 0.60 (0.33-1.12) after adjustment for OCSP classification, age, and sex; and 0.30 (0.08-0.97) in total anterior circulation infarction stroke type after full adjustment. CONCLUSIONS: Our data suggest that treatment with A-I might reduce short-term mortality in older patients with acute ischemic stroke. Randomized clinical trials should confirm this possible specific effect of A-I.

Abstract

BACKGROUND: Stroke is the third cause of death in older people living in Western countries. We tested the hypothesis that angiotensin-converting enzyme inhibitors (A-I) might affect short-term (30 day) mortality in older persons with severe acute ischemic stroke. METHODS: We analyzed data from a retrospective study including 475 consecutive older patients hospitalized for acute ischemic stroke. Mean age was 78.4 +/- 9.2 years; 58.2% were female. Stroke type was classified according to the Oxford Community Stroke Project (OCSP). RESULTS: Mortality rate was 28%. Thirty-two percent of patients were treated with A-I; mortality was 16.5% in patients treated compared with 33.3% in those not treated (chi(2) p =.001). The odds ratio for mortality in treated patients was: 0.47 (0.25-0.89) after full adjustment (age, sex, mean diastolic and systolic blood pressure, previous stroke and/or transient ischemic attack, congestive heart failure, atrial fibrillation, diabetes, hypertension, coronary heart disease, and previous treatment with A-I); 0.29 (0.09-0.89) in patients with altered level of consciousness after full adjustment; 0.60 (0.33-1.12) after adjustment for OCSP classification, age, and sex; and 0.30 (0.08-0.97) in total anterior circulation infarction stroke type after full adjustment. CONCLUSIONS: Our data suggest that treatment with A-I might reduce short-term mortality in older patients with acute ischemic stroke. Randomized clinical trials should confirm this possible specific effect of A-I.
