Correlates of bundle-branch block in patients undergoing primary angioplasty for acute myocardial infarction.

abstract：:Coronary artery disease (CAD) is still the number-one killer in the world, and clinical trials indicate that it is preventable. Mortality and morbidity can be reduced by at least 30% to 40% by treating known risk factors. Genetic susceptibility is claimed to account for 50% of predisposition. The challenge of preventi...
