Brain C-13

Beta-blocking drugs help prevent angina Brain C-13 Review attacks by slowing the rate at which the heart beats, thereby reducing the heart's workload and lowering the amount of oxygen it needs. These drugs should be taken exactly as instructed, and should not be stopped abruptly.A new class of anti-anginal drugs known as calcium-blocking agents appears to be particularly effective in controlling the type of angina associated with coronary spasm. All muscles require varying amounts of calcium in order to constrict; by reducing the amount of calcium that enters the muscle cells in the coronary vessel walls, the spasms that choke off the heart's blood supply may be prevented.In some patients, coronary bypass surgery may be recommended. This operation entails taking a portion of a vein, usually from the leg, and grafting it to the coronary artery to bypass the clogged area. Many factors are considered in deciding whether or not to operate, including the extent of coronary disease, degree of disability from the angina, and the age and general physical condition of the patient.
