- In 787 patients with acute myocardial infarction originally participating in the Göteborg Metoprolol Trial, mortality and morbidity during 5 years' follow-up were assessed and related to whether patients had diabetes mellitus. Diabetes occurred in 78 patients (10%). Patients with diabetes had a different risk factor pattern, including higher age, higher occurrence of angina pectoris and hypertension, whereas smoking habits did not differ. In the early phase (hospitalization), patients with diabetes had a higher mortality (12% versus 8%), required more treatment for heart failure and stayed longer in hospital. Other morbidity aspects, such as severity of pain, occurrence of severe supraventricular and ventricular arrhythmias, high-degree AV-block and infarct size did not differ. During 5 years' follow-up mortality rate in patients with diabetes mellitus was 55% as compared with 30% among patients with no diabetes (P<0.001). Reinfarction rate during 5 years was 42% in daibetics versus 25% in non-diabetics (P<0.001). In a multivariate analysis, taking into account the differences in risk factor pattern, diabetes turned out to be an independent determinant for long-term mortality and reinfarction (P<0.001). We conclude that patients with diabetes mellitus, developing acute myocardial infarction, is a group with particularly high risk of death and reinfarction. Interventions aiming at its reduction have priority.

- Parasympathetic denervation of the urinary bladder results in supersensitivity to muscarinic agonists and in bladder hypertrophy. In the present study, the effects of denervation on the muscarinic receptors in the rat bladder were investigated, using a receptor binding technique with (-)3H-QNB as radioligand. The density of muscarinic receptors was increased in denervated, hypertrophied bladders but it was decreased, below that in control bladders, when the development of hypertrophy was prevented by urinary diversion. A decreased receptor density was also found in innervated bladders after urinary diversion, whereas the receptor density was unaffected by hypertrophy alone. Competition experiments with methacholine revealed no changes in the agonist binding properties of the receptors. When the present data are combined with those in previous functional studies, it seems unlikely that the muscarinic receptors in the bladder are involved in the development of supersensitivity. It is suggested that the density of muscarinic receptors in the bladder may be related to the bladder function.
