title: [Should the occurrence of a first coronary event change the management of diabetes?].
abstract: The coronary morbi-mortality is particularly high in type 2 diabetes, which represents the vast majority of all diabetes. Hyperglycemia is an independent vascular risk factor in the short and long-term. The relationship between the degree of hyperglycemia and vascular risk is linear with no threshold effect. The occurrence of a first coronary event is an occasion, though late, to review the management of all risk factors in diabetic patients. In these patients, intensive insulin therapy administered in the acute phase of infarction reduces cardiovascular mortality by 30% at 1 and 3 years. There are no specific studies of secondary prevention by optimal therapy of diabetes, but, in the UKPDS, the treatment of hyperglycemia with sulfonylurea or insulin only marginally reduced the number of cardiovascular events. On the other hand, treatment of obese patients with metformin significantly reduced the incidence of myocardial infarction and of mortality diabetes related. These results, though observed with the same level of glycemic control as in the other treatment groups, suggest a cardio-protective effect of metformin itself. These beneficial effects should be weighed up against the potential risk of lactic acidosis which still limits the widespread use of metformin in with coronary heart disease patients. Follow-up studies show that diabetic with coronary heart disease patients do not receive all effective therapeutic inventions in secondary prevention and that the treatment of hyperglycemia is often neglected. Close collaboration between cardiologists and diabetologists is necessary to improve the management of type 2 diabetes.
