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
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
Heart arteries : The coronaries arteries branch off the aorta and run on top of the heart muscle, they provide blood, nutrients and oxygen to the heart muscle for it to keep pumping. When those arteries are blocked the heart muscle can die in a process called heart attack causing the patient to die or causing permanent muscle damage and heart failure. ...Read moreSee 1 more doctor answer
Medical therapy: if one has a tendancy for vascular disease - coronary artery disease being one area we are concerned about - then we have a reasonable set of recommendations to minimize disease progression, and even cause regression. These recs include: optimal weight, daily exercise, low fat/veg/mediterranean diets, lipid Rx, aspirin. other medicines like beta blockers or acei inhibitors can be helpful ...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
What is the relationship between coronary artery disease, coronary heart disease and ischemic heart disease?
Multiple ways: Coronary artery disease can cause symptoms, heart damage, or death. Symptoms include chest pain or shortness of breath. Heart damage is typically do to myocardial infarction (heart attack). Death can be due to heart failure, heart attack, or lethal arrhythmia. ...Read moreSee 1 more doctor answer
What is the relationship between coronary artery disease, coronary heart disease, and ischemic heart disease?
All related: Ischemic heart disease is caused by coronary artery disease. Some people call coronary artery disease coronary heart disease. When a coronary artery closes up, the heart tissie it supplied may die and that is called a heart attack. The dead heart tissue scars down, when there is a lot of damaged tissue the heart may start failing and that is called ischemic heart disease. ...Read moreSee 1 more doctor answer
Dominant Behavior: The key issue: atherosclerosis, an accumulation of white blood cells in the walls of arteries, typically starts in childhood & primarily driven by lipoproteins (the proteins which transport fat in the water outside cells) is dominant human behavior yet is typically ignored because it remains asymptomatic for decades until plaque rupture releases debris, triggers clots & suddenly blocks blood flow. ...Read moreSee 1 more doctor answer

What's mean mild coronary artery disease involving the left anterior descending and the right coronary artery? It's something to worry? Heart attack?
MDs visual judgement: I would be quite wary of the assessment, likely based on a coronary angiogram. Get a copy of all the images, on a cdrom from hospital, &closely examine yourself. Do not settle for someone else's interpretation, its not their body/heart. Any narrowing (stenosis) means advanced atherosclerosis with previous plaque ruptures; clots which have fibrosed/not-cleared; narrowed the opening of the artery. ...Read moreSee 1 more doctor answer
Prinzmetal angina.: Spasm can happen in any blood vessel including the coronaries. The inner lining of the arteries have ability to produce a relaxing factor now known to be nitric oxide. However, diseased arteries have dysfunctional inner lining cells that can't make the relaxing factor and thus can present with spasm also known as prinzmetal angina. ...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
Definition and cause: Angina isused to describe heart pain that specifically comes from an obstruction to the heart muscle's blood supply.The causes can be due to mechanical obstruction like a plaque, a clot or a combination. The heart arteries are muscular and can constricy and relax. Constriction (often found where there is clot and inflammation) of the arteries, or spasm, can contribute or in some cases cause angina. ...Read moreSee 1 more doctor answer
Symptom, Disease: Angina and angina equivalents are symptoms of cad: coronary artery disease - which is often pooled with other heart aliments and described as heart disease. Heart disease could potentially encompass other conditions such as congestive heart failure, chf, atrial fibrillation or flutter, af, kinds of cardiomyopathy, bundle branch block, and valve disorders and potentially more. ...Read moreSee 1 more doctor answer
They are related: But the technical difference would be related to whether the blockages in the arteries (coronary disease) are causing the heart to get less blood flow and oxygen than it needs to function properly (ischemic disease). You can have coronary disease without ischemia, but other than unusual conditions, it's less likely to have ischemia without coronary disease. ...Read more
The leading cause of death and disability in adults in the U.S. It develops when lipid (fatty) plaques builds up in the arteries, 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
