An antiplatelet agent prevents blood platelet adhesion and the formation of blood clots in the arteries. After a clot has formed and has caused a heart attack, medication can be injected to dissolve the clot. If given soon enough after the onset of the symptoms of a heart attack it can prevent permanent damage to the heart muscle cells. The pain from angina is similar to the pain from heart attack in location and character, but heart attack pain lasts longer and is often more severe. 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 doctor 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 defence 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.
