A complete blockage of blood flow can cause a heart attack. Treatment for coronary artery disease may include medicines and surgery. Eating a nutritious diet, getting regular exercise and not smoking can help prevent coronary artery disease and the conditions that can cause it.
Know the warning signs of this common heart condition often caused by clogged, narrowed arteries and how lifestyle changes can lower your risk.
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).
Coronary angioplasty and stent placement can greatly increase blood flow through a previously blocked or narrowed heart artery. Your doctor can compare images of your heart taken before and after the procedure to determine how well the angioplasty and stenting has worked.
Bundle branch block is a condition in which there's a delay or blockage along the pathway that electrical impulses travel to make the heart beat. It sometimes makes it harder for the heart to pump blood to the rest of the body.
In aortic valve stenosis, the valve is narrowed and doesn't open fully. This reduces or blocks blood flow from the heart to the aorta and to the rest of the body. Treatment of aortic stenosis depends on how severe the condition is. Treatment may include surgery to fix or replace the valve.
Plaque can cause an artery to become narrowed or blocked. If a plaque ruptures, a blood clot can form. Plaque and blood clots can reduce blood flow through an artery. A buildup of fatty substances in the arteries, called atherosclerosis, is the most common cause of coronary artery disease.
A heart attack occurs when the flow of blood to the heart is severely reduced or blocked. The blockage is usually due to a buildup of fat, cholesterol and other substances in the heart (coronary) arteries.
Women are more likely than men to have a heart attack with no severe blockage in an artery. When this happens, it's called nonobstructive coronary artery disease. Also, women tend to have blockages not only in their main arteries but also in the smaller ones that supply blood to the heart.
A coronary angiogram is done to look for narrowed or blocked blood vessels in the heart. Your healthcare team may suggest a coronary angiogram if you have: Chest pain, called angina. Pain in the chest, jaw, neck or arm that can't be explained by other tests. Blood vessel problems.
