Current concepts in the pathogenesis of atrial fibrillation.

abstract：BACKGROUND:Although angiotensin-converting enzyme inhibitor attenuates ventricular enlargement, whether beta-blocker therapy induces regression of left ventricular remodeling is not known. The purpose of this study was to compare the effects of bisoprolol therapy with those of imidapril therapy on left ventricular remo...
