What causes thrombosis of the coronary arteries?

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 more

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 more

Will midodrine cause any vasoconstriction of coronary arteries aswell?

Will midodrine cause any vasoconstriction of coronary arteries aswell?

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 more

What would cause a high coronary artery score and yet after a angiogram there isn't a blockage?

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

Does a cigarette cause coronary artery vasoconstriction? If yes, wouldnt this cause a angina if you started exercising?

Does a cigarette cause coronary artery vasoconstriction? If yes, wouldnt this cause a angina if you started exercising?

Smoking does: increase the risk of an acute cardiac event, because it is a vasoconstrictor and it causes blood to be more coagulable, among other reasons. Because it increases the risk, doesn't mean it will happen all the time. ...Read more

My friend has blocked coronary arteries. What are the possible causes?

My friend has blocked coronary arteries. What are the possible causes?

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

How will fat cause coronary artery disease?

How will fat cause coronary artery disease?

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 more
