Beta-adrenergic blockers work by reducing the heart rate and contractility of the heart, resulting in a decrease in oxygen demand and a reduction of angina symptoms. This is achieved through a negative inotropic effect, which reduces the force of contraction of the heart, and a negative chronotropic effect, which reduces the heart rate. These actions can help to decrease the workload of the heart and improve oxygen supply and demand balance, making them effective in treating angina.
