During this procedure, a straw-like tube is inserted into an artery in the patient's groin and a catheter is threaded up into the heart. An iodine-based dye is injected through the catheter into the coronary arteries, and pictures are obtained to see if partial or total blockages are present. Cardiac catheterization is also recommended for patients who continue to have anginal episodes despite medical therapy. Information is emerging that suggests long-term use of ACE inhibitors also may decrease the chance of future heart attacks in some patients. Cholesterol-reduction therapy decreases the chance of future heart attacks or strokes, as well as the need for angioplasty or bypass surgery.
Smoking cessation can dramatically decrease the risk of heart attack.
There is no easy way to stop smoking. Others get help from support groups, behavior modification, relaxation techniques, hypnosis, or acupuncture. People who have an inactive, sedentary lifestyle are more likely to develop coronary artery disease than those who are physically active or exercise regularly. Anyone who has had a heart attack should talk to their physician about devising an exercise program before increasing their activity. The doctor may recommend a cardiac rehabilitation program in a local hospital or community center.
