Platelet accumulation in experimental angioplasty: time course and relation to vascular injury.

abstract：BACKGROUND:Coronary artery disease (CAD) and myocardial infarction (MI) are caused in part by genetic factors. Recently, the MEF2A gene was linked to MI/CAD in a single pedigree with autosomal-dominant pattern of inheritance. In addition, genetic variants within the gene have been associated with MI in case-control set...
