the possible mechanisms of the benefit of beta-blockade in the prevention of cardiac damage are ( a ) reduction in the myocardial oxygen requirement by slowing the heart rate and lowering blood pressure and the velocity of left ventricular contraction , ( b ) reduction of infarct size , ( c ) prevention of catecholamine-induced myocardial necrosis , ( d ) prevention of catecholamine-induced life-threatening arrhythmias , ( e ) prevention of cardiac rupture , and ( f ) prevention of atheromatous plaque formation and rupture by reduction of arterial flow disturbance and wall stress .
