In addition to the direct positive effect on your cardiovascular system, relaxation techniques may help you make other lifestyle changes such as stopping smoking and contribute to a general sense of well-being.

Vitamin therapy may also work in conjunction with your medical treatment. High doses of niacin can lower blood cholesterol levels, reducing the buildup of fatty deposits in the arteries. In addition, recent studies indicate that vitamin E, an antioxidant vitamin that also inhibits blood clotting, may help reduce the risk of heart attack.

However, do not take any more than the Recommended Dietary Allowance RDA of any vitamin without first consulting your doctor; some vitamins in high doses can have toxic effects. Other more controversial, alternative therapies include garlic, which may be consumed as deodorized pills, and fish oil omega-3 fatty acid supplements. Ongoing studies indicate that large amounts of garlic may have a modest cholesterol-lowering effect.

Any benefits of fish oil supplements are offset by the increased calorie and fat intake. Thus, experts recommend eating one or two servings of salmon, cod, or other cold-water fish a week rather than taking fish oil pills. To get started today, call or use our appointment request form.

Causes of Coronary Heart Disease The narrowing is due to a buildup of fatty plaque atherosclerosis along the artery walls.

Medications for Coronary Artery Disease Various medications constitute the first-line treatment of coronary artery disease. These include: Beta-Blocking Drugs: These agents act by blocking the effect of the sympathetic nervous system on the heart, slowing heart rate, decreasing blood pressure, and thereby reducing the oxygen demand of the heart. Procedures for Coronary Artery Disease Blocked coronary arteries may be treated through angioplasty or surgery.

Hybrid Cardiac Surgery Options In some cases, there may be an opportunity to combine minimally invasive cardiac surgery and coronary stenting to obtain a personalized, lasting, and lower risk surgery. Home Remedies and Alternative Therapies for Coronary Artery Disease There is no substitute for medical care when considering a serious—even potentially fatal—condition such as coronary heart disease. However, your doctor may recommend nonmedical measures, such as: exercise conditioning, relaxation techniques such as yoga, and a low-fat diet.

Myocardial ischemia occurs when blood flow to the heart muscle myocardium is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques atherosclerosis.

If the plaques rupture, you can have a heart attack myocardial infarction. When they do occur, the most common is chest pressure or pain, typically on the left side of the body angina pectoris. Other signs and symptoms — which might be experienced more commonly by women, older people and people with diabetes — include:.

Myocardial ischemia occurs when the blood flow through one or more of your coronary arteries is decreased. The low blood flow decreases the amount of oxygen your heart muscle receives. Myocardial ischemia can develop slowly as arteries become blocked over time. Or it can occur quickly when an artery becomes blocked suddenly. If you have too many cholesterol particles in your blood, cholesterol may accumulate on your artery walls.

Eventually, deposits called plaques may form. The deposits may narrow — or block — your arteries. These plaques can also burst, causing a blood clot to form. The same lifestyle habits that can help treat myocardial ischemia can also help prevent it from developing in the first place. Leading a heart-healthy lifestyle can help keep your arteries strong, elastic and smooth, and allow for maximum blood flow. Your doctor will start by asking questions about your medical history and with a physical exam.

After that, your doctor might recommend:. The goal of myocardial ischemia treatment is to improve blood flow to the heart muscle.
