Treatment in Western medicine.
Nitroglycerin is the drug of choice; it acts in about 1 to 2 minutes. As soon as the attack begins, place one flesh 0.3mg tablet under the tongue and allow it to dissolve.
Amyl nitrite, 1 pearl crushed and inhaled, acts in about 10 seconds.
Sublingual nifedipine, 10 to 20mg, may rapidly relieve angina, especially if spasm is the cause.
Oral isosorbide dinitrate, 2.5 to 10mg, 3 or more times daily.
Beta-blocking agents:Propranolol (Inderal), 10 to 80mg, 3 to 4 times daily by mouth.
Platelet-inhibiting agents:Aspirin, 0.3g/per day.
Inhibitors of the calcium slow-channel ionicflux:
Nifedipine, I0 to 20mg, 3 times daily by mouth is often helpful, especially when the patient suffers from hypertension.
General measures:
The patient must avoid all habits and activities known to bring on an heart attack. Most patients with angina do not require prolonged bed rest, but rest and relaxation are beneficial. Adequate mental rest is also important. Obese patients should be placed on a reducing diet and their weight brought to normal or slightly subnormal levels. Use of tobacco should be stopped or avoided because it produces tachycardia and elevation in blood pressure and because cigarette smoking has been shown to be a risk factor in coronary heart disease.
