Genetics and Genomics of Congenital Heart Disease.

abstract：:To determine the effects of aging on the human myocardium, 67 hearts were obtained from individuals who died from causes other than cardiovascular disease. The age interval examined was 17-90 years. Regression analysis demonstrated that the aging process was characterized by a loss of 38 million and 14 million myocyte...
