Objectives & Aims: The evaluation and identify new prognostic markers suggested in recent studies for coronary heart disease ,raised platelets distribution width (PDW) has been found to be associated with poor prognosis after resent myocardial infarction. Evaluate the relationship between raised PDW and mortality morbidity after the initial attack of myocardial infarction (MI). Increased platelets distribution width (PDW) has been associated with adverse outcomes. We studied the association between raised PDW during hospital course with clinical outcomes survival index of patients with after acute myocardial infarction (AMI
