Coronary Artery Disease Air Embolism
Will a CT angiogram of the coronary arteries reveal a pulmonary embolism or other lung disease and is it harmful to have 2 CT scans in the same month?
It might: A CT angiogram or the coronaries might show a pulmonary embolism, provided that the radiologists obtained full field of view reconstructions (some do not) and the pulmonary embolism is not higher or lower than the field of view. most often, the answer would be yes, a significant PE would be identified on this type of scan. having two ct's in the same month is not optimal, but likely of no harm. ...Read more
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
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
Yes: "drugs" is a vague term but if you mean recreational drugs then yes. Marijuana is as bad if not worse than cigarettes. No filter, held for extended time in lungs, and often contains unknown contaminants.So if smoking is a known risk factor....Cocaine tends to cause intense coronary artery vasospasm.This can damage the endothelium and allow cholesterol to deposit in the vessels. ...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
CAD: By reducing the demand and increasing the coronary blood supply we can pharmacologically reduce anginal symptoms and manage CAD medically. Beta-blockers, nitrates, and calcium channel blockers can help. Aspirin reduces the risk of mi by making platelets less likely to stick together and cause clots. Lipi-lowering meds like statins can stabilize and slow progression of blockages. ...Read more
Blood vessels are made to carry blood - liquid. A small amount of air in a vessel is not usually a big deal as it will be absorbed into the blood. Larger volumes of air (10 mL or larger) can be significant to block blood flow in that vessel. That is bad in the brain (stroke) and really bad in the heart because ...Read more
Usually a blood clot that migrates from one area of the body to another. Most commonly a clot from a leg vein to the lung . It can also pertain to a clot, or atheromatous material that moves from one segment to another, such as cholesterol material in a carotid lesion moving into the ...Read more
