Sudden death and silent myocardial ischemia.

abstract：BACKGROUND:Advanced age is a well-established prognostic risk factor after acute myocardial infarction (AMI), yet approximately 10% of MIs occur in patients <45 years. We examined characteristics, cardiovascular outcomes, and the influence of risk factors on outcomes in young survivors of AMI. METHODS:Fourteen thousan...
