[Angina pectoris. Results of investigations to date (author's transl)].

Among the most important coronary risk factors are a diet rich in saturated fatty acids, cholesterol and calories, hypercholesterolemia, high blood pressure and excessive smoking. The typical pain can be elicited by putting a strain on the patient, e.g. climbing stairs. The disappearance of the pain after treatment with nitroglycerine is one of the most important pointers. Treatment is with nitroglycerine which, moreover, remains the drug of choice, also with nitrates such as pentaerythritol tetranitrate and with betablockers like propranolol. Favorable results have also been reported with a combination of isosorbide dinitrate and propranolol.
