Causes of Myocardial Ischemia Open the popup dialog
Myocardial ischemia occurs when blood flow to your heart is reduced, which prevents the heart muscle from receiving enough oxygen. Reduced blood flow is usually the result of partial or complete blockage of the arteries in your heart (coronary arteries).
- Myocardial ischemia, also called cardiac ischemia, decreases the ability of the heart muscle to pump blood. A sudden and severe blockage of one of the arteries in the heart can lead to a heart attack. Myocardial ischemia can also cause serious abnormal heart rhythms.Myocardial ischemia Treatment Khammam
Some people with myocardial ischemia have no signs or symptoms (silent ischemia).
- When they occur, chest pressure or pain is most common, usually on the left side of the body (angina pectoris). Other signs and symptoms that may be more common in women, the elderly, and people with diabetes include:Myocardial ischemia Treatment Khammam
- Pain in the neck or jaw

Myocardial ischemia occurs when blood flow to one or more of your coronary arteries is reduced. Poor blood circulation decreases the amount of oxygen your heart muscle receives.Myocardial ischemia Treatment Khammam
- Myocardial ischemia can develop slowly if the arteries become blocked over time. Or it can happen quickly if an artery suddenly becomes blocked.
Conditions that can cause myocardial ischemia include:
- Coronary artery disease (atherosclerosis). Plaques, which are mostly made up of cholesterol, build up on the walls of your arteries and restrict blood flow. Atherosclerosis is the leading cause of myocardial ischemia.
- Blood clot. The plaques that develop with atherosclerosis can burst and cause a blood clot. The clot can block an artery and cause sudden and severe myocardial ischemia, which leads to a heart attack. In rare cases, a blood clot can travel to the coronary artery from elsewhere in the body.
Factors that can increase your risk of developing myocardial ischemia include:
- The tobacco. Smoking and prolonged exposure to secondhand smoke can damage the inner walls of the arteries. The damage can cause deposits of cholesterol and other substances to build up and slow blood flow in the coronary arteries. Smoking causes coronary artery spasms and can also increase the risk of blood clots.
- Diabetes. Type 1 and type 2 diabetes are associated with an increased risk of myocardial ischemia, heart attack, and other heart problems.
- Arterial hypertension. Over time, high blood pressure can accelerate arteriosclerosis and damage the coronary arteries.
- High blood cholesterol. Cholesterol is an important part of the buildup that can cause your coronary arteries to constrict. High levels of “bad” cholesterol (low-density lipoprotein, or LDL) in your blood may be due to an inherited disease or a diet high in saturated fat and cholesterol.
- High levels of triglycerides in the blood. Triglycerides, another type of blood fat, can also contribute to atherosclerosis.Myocardial ischemia Treatment Khammam
The same lifestyle habits that can help treat myocardial ischemia can also help keep it from developing at all. Living a heart-healthy lifestyle can help keep your arteries strong, elastic, and smooth, and allow for maximum blood flow.Myocardial ischemia Treatment Khammam
