In this test, a very long and very thin tube is inserted through an artery in the arm or leg and then guided into the heart. Dye is injected into the arteries around the heart. X-rays are taken. If any of the arteries that supply the heart are blocked, the x-rays will show it. These blockages can cause angina and put you at risk of a heart attack.
Prevention is the best treatment.
Whether you have these conditions or not, maintaining a healthy diet, a healthy weight and a regular exercise program can help you avoid coronary artery disease. Hormone replacement therapy with a medicine called estrogen also may help prevent coronary artery disease in women after menopause. If you already have coronary artery disease, controlling blood pressure, diabetes and cholesterol and quitting smoking are important to keep the problem from getting worse. A healthy diet, a healthy weight and a moderate, regular exercise program are also important in people with coronary artery disease. Most people with heart disease need to take medicine.
