How does ischemic heart disease affect the body?
Ischemic heart disease reduces the flow of blood to the coronary arteries, which carry oxygen to the heart. This reduction in blood flow may result in a number of symptoms, which can vary in intensity among individuals.
What organs does ischemic heart disease affect?
Ischemic heart disease, also called coronary heart disease (CHD) or coronary artery disease, is the term given to heart problems caused by narrowed heart (coronary) arteries that supply blood to the heart muscle.
What is a cause and effect of ischemia?
Ischemia is caused by a decrease in blood supply to a tissue or organ. Blood flow can be blocked by a clot, an embolus, or constriction of an artery. It can occur due to gradual thickening of the artery wall and narrowing of the artery, as in atherosclerosis. Trauma can also disrupt blood flow.
Because ischemic heart disease is caused by a lack of oxygen-rich blood to the heart, your heart may be damaged, even to the point of being unable to pump blood to the rest of your body.
How does ischemic heart disease differ from chronic IHD?
Ischemic Heart Disease. In contrast, in chronic IHD the presence of flow-limiting coronary lesions restricts the ability of the heart to increase blood supply in response to increases in myocardial oxygen demand, resulting in development of angina pectoris, a transient discomfort in the chest and neighboring areas.
How is ischemic heart disease related to inadequate oxygen supply?
Because the fundamental pathophysiologic defect in the ischemic myocardium is inadequate perfusion, ischemia is associated not only with insufficient oxygen supply, but also with reduced availability of nutrients and inadequate removal of metabolic endproducts.
What does The Lancet say about ischemic heart disease?
Lancet 367, 1747–1757. The term ischemic heart disease (IHD) describes a group of clinical syndromes characterized by myocardial ischemia, an imbalance between myocardial blood supply and demand.
What does it mean to have ischemic heart disease?
Ischemic heart disease is also known as coronary artery disease or “hardening of the arteries.”. Cholesterol plaque can build up in the arteries of the heart and cause “ischemia,” which means the heart is not getting enough blood flow and oxygen.
What happens to your body when you have ischemia?
You usually get ischemia because of a build-up or blockage in your arteries. What it feels like and how it affects you depends on where you get it. But it can lead to life-threatening problems like a heart attack or stroke. Why Does It Happen? One of the main causes of ischemia is atherosclerosis. That’s where plaque collects in your arteries.
Who is most at risk for ischemic heart disease?
For this reason, ischemic heart disease occurs most frequently in people who have atherosclerosis (buildup of plaque on the walls of the coronary arteries), blood clots, coronary artery spasm, or severe illnesses that increase the heart’s need for oxygen. What are the risk factors for ischemic heart disease?
How does stress increase the risk of ischemic heart disease?
Stress, which can trigger the tightening of your arteries, which increases your risk of ischemic heart disease, especially coronary microvascular disease. Stress may also indirectly raise your risk of ischemic heart disease if it makes you more likely to smoke or overeat foods high in fat and added sugars.
