title: The effect of sulphonylurea therapy on the outcome of coronary heart diseases in diabetic patients.
abstract: A retrospective study was performed on 1040 diabetic patients. The survival time of those treated with first generation sulphonylureas (n = 227) was considerably (P < 0.001) shorter after the first attack of angina pectoris (5 +/- 1 years, mean +/- S.E.) or acute myocardial infarction (6 +/- 1 years) than of those (9 +/- 1 years) on glibenclamide treatment (n = 144), with regime alone (n = 282) or treated with insulin (n = 387). The systolic blood pressure of patients with first generation sulphonylureas (166 +/- 1/91 +/- 1 mmHg) proved to be higher (P < 0.01) than those treated with glibenclamide (159 +/- 1/91 +/- 1 mmHg) or being on regime alone (155 +/- 1/89 +/- 1 mmHg) or on insulin (156 +/- 1/89 +/- 1 mmHg) treatments. Serum sodium level was found to be lower (P < 0.05) in patients treated with any kind of sulphonylureas (138 +/- 1 mmol/l) than in the other patients (143 +/- 1 mmol/l). During an observation period, 576 of patients died, 412 of them due to cardiovascular or renal failures. Among the diabetic subjects suffering from coronary heart disease no difference could be detected in risk factors except for higher systolic blood pressure. The shorter survival time of patients treated with first-generation sulphonylureas might be explained by the arrhythmogenic activity of first-generation sulphonylureas. Improvement in therapy, metabolic and cardiovascular alterations during the survey can not be responsible for the shorter survival time of patients treated with first generation-sulphonylureas.
