The most accurate way to assess the presence and severity of coronary disease is a coronary angiogram, an x-ray of the coronary artery. X-rays of its distribution show the coronary arteries and their narrowing. These include high blood pressure, cigarette smoking, high blood cholesterol levels, and excess weight. If the doctor has prescribed a drug to lower blood pressure, it should be taken as directed.
Advice is available on how to eat to control weight, blood cholesterol levels, and blood pressure.
A physician can also help patients to stop smoking. Taking these steps reduces the likelihood that coronary artery disease will lead to a heart attack. Most people with angina learn to adjust their lives to minimize episodes of angina, by taking sensible precautions and using medications if necessary. Usually the first line of defense involves changing one's living habits to avoid bringing on attacks of angina. Controlling physical activity, adopting good eating habits, moderating alcohol consumption, and not smoking are some of the precautions that can help patients live more comfortably and with less angina.
