Do calcium channel blockers reduce myocardial oxygen consumption? The more cardioselective CCBs (verapamil and diltiazem) decrease heart rate and contractility, which leads to a reduction in myocardial oxygen demand, which makes them excellent antianginal drugs.
Do calcium channel blockers increase myocardial oxygen supply? Additionally, the vasodilatory effects of calcium-channel blockers on vascular smooth muscle resulting in an increase in myocardial oxygen supply [10].
How do calcium channel blockers reduce myocardial oxygen demand? Calcium channel blockers (Chapter 11) reduce systemic vascular resistance and decrease myocardial contractility. Nitrates (Chapter 11) will produce venous dilation, which will decrease preload and decrease oxygen demand by the heart.
What medication decreases myocardial oxygen demand? Vasodilators, such as the nitrates or sodium nitroprusside, decrease cardiac filling pressures, and increase myocardial blood flow, thus lowering myocardial oxygen consumption. Phosphodiesterase inhibitors (amrinone, enoximone) have both an inotropic and a vasodilating effect.
