Lifestyle:
When angina is caused by coronary artery disease, treatment often involves changes in your lifestyle. This may include:

• quitting smoking
• losing weight
• reducing stress
• getting more regular exercise, as prescribed by your doctor
• lowering your blood pressure (if high)
• lowering your blood cholesterol (if high)
• lowering your blood sugar (if high).

Medicine:
Often the symptoms of angina can be controlled with medicine. Nitrates such as nitroglycerin increase the blood flow to the heart. They reduce the workload on the heart by dilating (expanding) the coronary blood vessels and lowering blood pressure slightly. Drugs called beta blockers and calcium channel blockers are also effective. Other medicines your doctor may prescribe are ACE (angiotensin-converting enzyme) inhibitors, aspirin, and cholesterol-lowering medicines. Your doctor will determine which type of medicine is right for you based on your test results and any other medical problems you have.

Surgery:
Angina caused by blocked arteries can be treated with two types of procedures: balloon angioplasty and coronary artery bypass graft surgery.

Balloon angioplasty is a simpler procedure than coronary bypass surgery. A tube with a balloon tip is placed in your artery. The balloon is inflated where the artery is blocked. This expands the artery enough to let blood flow normally. Most people have a stent inserted as part of this procedure to help keep the artery open. The balloon is then deflated and both the balloon and the tube are removed from your artery. You may need to stay at the hospital a day or two after the procedure.

In coronary artery bypass graft surgery, blood vessels are taken from other parts of your body and attached to the blocked coronary arteries on either side of the blockage. The blood is then able to flow around, or bypass, the blockages. You will likely stay in the hospital about 1 week, and then recover at home for several weeks.
