Survival, integration, and differentiation of cardiomyocyte grafts: a study in normal and injured rat hearts.

abstract：BACKGROUND:The synthetic catecholamine dobutamine increases stroke volume in normal subjects and in patients with congestive heart failure. In addition to its direct influence on myocardial contractility, dobutamine may significantly modulate vascular tone because of its alpha- and beta-adrenergic agonist activity. ME...
