Sammanfattning

OBJECTIVES: Previous studies have shown that patients with diabetes mellitus have an increased mortality after suffering from acute myocardial infarction (AMI). Patients with diabetes have several risk factors for cardiovascular disease. Our objective was to quantify the prevalence of pharmacological cardiovascular prevention at admission and relate such treatment to short and long-term mortality following AMI in patients with and without diabetes. DESIGN AND SUBJECTS: All patients discharged from the Department of Internal Medicine at Helsingborg Hospital in 1996 and 1997 with a principal diagnosis of AMI were included in the study. Patients were divided into two groups according to the presence or absence of diabetes. Cardiovascular risk factors, on-going medication, type of ward following admission, peak creatine kinase MB mass (CKMB) and immediate treatment were registered. Information about death was obtained from the national register. Kaplan-Meier analysis was performed for life-expectancy. RESULTS: A total of 673 patients with AMI were registered, of which 117 (17.4%) had diabetes. No differences in 30 days (17.1% vs. 15.3%) or 1-year (24.8% vs. 27.4%) mortality were seen between the diabetes and control groups, whereas the 2-year mortality was significantly higher in the diabetes group (40.2% vs. 29.1%). Cardiovascular risk factors occurred more often in the diabetes group and the use of aspirin, ACE-inhibitors, statins and diuretics was significantly more frequent. In patients treated with aspirin, in combination with either statin or angiotensin converting enzyme (ACE)-inhibitor, or both, no differences were seen in 30 days, 1 or 2-year mortality between groups. CONCLUSION: In contrast to earlier studies we did not find an increased 30 days and 1-year mortality in patients with diabetes suffering from AMI. This discrepancy was linked to a higher frequency of pharmacological cardiovascular prevention, a finding supporting the hypothesis that survival of a diabetes patient after AMI could be affected by factors operating before the infarction.
