Where Does Coronary Artery Disease Originate
CAD: Coronary artery disease, just as disease in other arteries, is the result of a long time process initiated by: 1. Genetic pre-disposition 2. Uncontrolled/untreated high blood pressure, diabetes, cholesterol/triglycerides 3. Smoking, obesity, lack of exercise, stress. ...Read moreSee 1 more doctor answer
Coronary artery disease is the leading cause of death and disability in adults in the U.S. It develops when lipid (fatty) plaques builds up in the arteries. Eventually, the plaque can occlude the artery, thereby stopping blood flow to the organ supplied by that artery. If the artery supplies the heart, blockage causes a heart attack. If the blockage is in a brain vessel, the ...Read more
Slowly: Low density lipoprotein (ldl) is taken up by endothelial cells in blood vessels. The LDL is broken down (oxidized) and absorbed by macrophages within the wall of the blood vessel. Ultimately, the macrophage which is full of oxidized LDL will die. The dead cells and cholesterol accumulate in the wall of the artery interfering with the flow of blood. ...Read moreSee 1 more doctor answer
Symptoms/lifespan: Coronary artery disease affects the quality of life and the length of life. Quality of life is affected by reduced functional capacity (ability to do things), chest pain, shortness of breath, loss of employment, and hospitalization. Length of life is reduced as a result of sudden death and myocardial infarction. ...Read moreSee 1 more doctor answer
By blocking the flow: In young, healthy individuals the inner lining of the blood vessels is clean and smooth. Overtime, for many reasons, the inner surface of the heart blood vessels (coronary arteries) may start becoming bumpy/lumpy or blocked due to fat (cholesterol) deposits called "atherosclerotic plaque". This in turn reduces the amount of blood flow available causing "ischemia" (oxygen deprivation). ...Read more
Does coronary artery disease directly cause ventricular tachycardia or is it after heart attacks and damage etc?
CAD: Coronary artery disease is defined as obstructive lesions in the coronary arteries that supply the heart muscle . These start as areas of inflammation that progress into obstructions and affect the different layers of the blood vessel wall (from inside out). ...Read moreSee 1 more doctor answer
Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more
