What Causes Thrombosis Of The Coronary Arteries
Arterioclerosis: Arteriosclerosis or plaque buildup in the wall of the coronary arteries will narrow the lumen to the point where there is flow restriction, then clot formation. The plaque may rupture, allowing a flap-like effect, blocking the lumen, resulting in clot formation. Trauma may cause a separation of the layers of the wall, and this dissection results in clot formation. ...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
Can a thrombosis of right coronary artery just lie there dormant not doing anything or nor causing harm ?
RCA: The RCA supplies the right atrium and ventricle. A complete blockage will cause a major heart attack. A thrombosis is NOT a dormant situation. It is restricting flow. How much restriction guides therapy. At a minimum medical therapy would be necessary (aspirin, plavix, (clopidogrel) statins etc). ...Read moreSee 1 more doctor answer
If a body had a thrombosis of right coronary artery at post-mortem, is that a sign of a DEFINITE heart attack ?
Anomalies: these are abnormal structure or location or distribution of vessels seen in a patient. They are usually caused by having the wrong parents or by bad luck ...Read more
Several: There are a number of risk factors that lead to plaque in the coronary arteries which is the reason for the blockage. Some of these are smoking, high blood pressure, unhealthy diet, an abnormally high cholesterol, lack of exercise, and obesity. There are also hereditary factors. ...Read moreSee 2 more doctor answers
Yes : Yes you can call spasm of the corner arteries avoid this with significant coronary disease. ...Read more
Congenital: They're errors of the coronary anatomy that you're born with. Most are benign. A few are potentially lethal. ...Read more
No evidence seen: Mididrine is an alpha1-agonist and exerts its actions via activation of the alpha-adrenergic receptors of the arteriolar and venous vasculature, producing an increase in vascular tone and elevation of blood pressure. There is some recent evidence in animal coronaries there are Alpha and beta receptors in large coronaries and beta in small coronaries, but no data avialabe for midodrine. ...Read moreSee 1 more doctor answer
Not unusual: The calcium score is a measure of calcium in the wall of the artery. An angiogram measures the degree of blockage in the lumen of the artery. A high calcium score is a measure of the risk of devolping obstructive coronary disease; it does not make the diagnsosis of obstructive coronary disease. ...Read more
If nicotine causes coronary artery constriction, after a cigarette how long would this effect last?
Nicotine: elimination half time is about 2hrs, in roughly 10hrs its pretty much gone, the coronary constriction will be decreasing after 2hrs but complete time to resolution will vary person to person ...Read more
Does a cigarette cause coronary artery vasoconstriction? If yes, wouldnt this cause a angina if you started exercising?
Atherosclerosis: Far and away the most common reason for this is build up of plaque in the arteries, called atherosclerosis. This is caused by a combination of high blood pressure, smoking, high cholesterol, and aging. Reducing these risk factors (we can't do anything about age except exercise!) helps prevent this from happening. ...Read more
LDL Cholesterol: More specifically, LDL (low density lipoprotein) cholesterol gets deposited within the walls of the arteries. These deposits, known as plaque, can continue to build up causing narrowing of the arteries and may lead to blockage. If the involved arteries are in the coronary arteries, this leads to heart disease. ...Read moreSee 1 more doctor answer
