Conclusions (1) Diabetes is associated with increased mortality after AMI and unstable angina Loss of ‘R’ to ‘R’ variability and PG on admission are associated with increased mortality in diabetic patients with AMI Outcome after AMI may be improved with tight glycaemic control in the acute stage Mater Dei Hospital, Malta
Conclusions (2) Diabetic patients with ACS should be managed aggressively to lower this risk Diabetic patients with renal disease are at a particularly risk; this is probably partly genetically mediated There is loss of circadian rhythm in the onset of AMI & APE in diabetic patients~ ? implications for chronopharmacology Mater Dei Hospital, Malta
