Topic: Coronary disease


  
  Encyclopedia: Coronary heart disease
Coronary heart disease (CHD), also called coronary artery disease (CAD) and atherosclerotic heart disease, is the end result of the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium (the muscle of the heart).
A coronary angiogram performed during this stage of disease may not show any evidence of coronary artery disease, because the lumen of the coronary artery has not decreased in caliber.
As the degree of coronary artery disease progresses, there may be near-complete obstruction of the lumen of the coronary artery, severely restricting the flow of oxygen-carrying blood to the myocardium.

While the symptoms and signs of coronary heart disease are noted in the advanced state of disease, most individuals with coronary heart disease would have evidence of disease decades before the first symptoms arise.
As the degree of coronary artery disease progresses, there may be near-complete obstruction of the (A cavity or passage in a tubular organ) lumen of the coronary artery, severely restricting the flow of oxygen-carrying blood to the myocardium.
The pain associated with very advanced CHD is known as (Any disease of the throat or fauces marked by spasmodic attacks of intense suffocative pain) angina, and usually presents as a sensation of pressure in the chest, arm pain, jaw pain, and other forms of discomfort.

Coronary artery disease is the most common underlying cause of cardiovascular disability and death.
The primary symptom is angina pectoris, a pain that radiates in the upper left quadrant of the body due to the lack of oxygen reaching the heart.
Another procedure is coronary artery bypass surgery, which splices veins or internal mammary arteries to the affected coronary artery in order to bypass the atherosclerotic blockage and supply blood to the heart muscle.

 Cardiac, Coronary Artery Disease
Coronary disease appears to be a lifelong process in some people, beginning at an early age and progressing slowly until the vessels become so occluded that the heart muscle no longer gets adequate nourishment.
A coronary artery must be narrowed to less than 30% of its original size before there is a serious reduction in the blood flow to the heart muscle served by that vessel.
A presumptive diagnosis of coronary disease is based on a review of symptoms, health history, an electrocardiogram, and an exercise stress test, perhaps with a thallium scan.

 Coronary Artery Disease
Coronary artery disease is the term commonly used to describe the buildup of fatty deposits and fibrous tissue (plaques) inside the arteries that supply blood to the heart (the coronary arteries).
Coronary atherosclerosis eventually can cause the coronary arteries to become significantly narrower, which decreases the blood supply to portions of the heart muscle and triggers a specific type of chest pain called angina.
Because the extent of coronary artery disease does not always match the severity and length of chest pain, it is important for patients with chest pain to have their symptoms evaluated promptly by a doctor.

Coronary artery disease, or CAD, is the leading cause of death in America: every year over 500,000 Americans die of heart attacks or other complications of CAD.
Also known as coronary heart disease, coronary artery disease occurs when the small arteries bringing oxygen-rich blood to the heart narrow, restricting blood flow.
Angina is a disease in which the arteries that supply the heart have narrowed, most commonly as a result of athersclerosis.

 Coronary Artery Disease
Coronary artery disease is characterized by the presence of atherosclerosis in the epicardial coronary arteries.
The reduction in coronary artery flow may be symptomatic or asymptomatic, may occur with exertion or at rest, and may culminate in a myocardial infarction, depending on obstruction severity and the rapidity of development.
Coronary artery bypass grafting produces better survival rates compared to medical therapy, and it is recommended for symptomatic patients with left main coronary artery disease, three-vessel coronary artery disease, or two-vessel coronary artery disease marked by stenosis of the proximal left anterior descending artery.

 Coronary Artery Disease Prevention - Information about Coronary Artery Disease Prevention
Coronary arteries may narrow due to a thickening of their walls and and this reduces blood flow to the heart muscle.
The coronary arteries narrow because fatty substances accumulate in their walls; we do not know the exact reason for this process: therefore we cannot completely prevent it.
Although the risk of coronary disease may not be completely abolished, it can be substantially reduced.

 Understanding Coronary Artery Disease
Coronary artery disease is a narrowing or blockage of the coronary arteries, the arteries that provide the heart muscle with blood.
When one or more of the coronary arteries are completely blocked, the result is a heart attack (injury to the heart muscle).
This is true if you do not have heart or blood vessel disease, if you are being treated medically for heart or blood vessel disease, or you have undergone a procedure (angioplasty, stents, bypass surgery) for heart or blood vessel disease.

Heart disease is caused by narrowing of the coronary arteries that feed the heart.
When the coronary arteries become narrowed or clogged by cholesterol and fat deposits--a process called atherosclerosis--and cannot supply enough blood to the heart, the result is coronary heart disease (CHD).
If you have too much cholesterol in your bloodstream, the excess is deposited in arteries, including the coronary arteries, where it contributes to the narrowing and blockages that cause the signs and symptoms of heart disease.

 What Is Coronary Artery Disease?
Coronary artery disease (CAD) occurs when the arteries that supply blood to the heart muscle (coronary arteries) become hardened and narrowed.
The arteries harden and become narrow due to the buildup of plaque on the inner walls or lining of the arteries (atherosclerosis).
Blood flow to the heart is reduced as plaque narrows the coronary arteries.

 Coronary Artery Disease
Coronary artery disease is when one or more of the coronary arteries becomes narrowed or totally blocked by a gradual build-up of fat (cholesterol) within the artery wall, which reduces blood flow to the heart muscle.
Your doctor may use several tests to determine if you have coronary artery disease, including an electrocardiogram (ECG) while you are resting and again while you are walking or running on a treadmill or pedaling a stationary bicycle.
Coronary artery disease may be treated with medication, surgery, minimally invasive interventional procedures, or a combination of these therapies.
