What Would Left Anterior Descending Coronary Artery Blockage Cause
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
What is the cpt code for a percutaneous transluminal coronary angioplasy of the left anterior descending coronary artery?
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
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
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
What could cause a high (1100+) right coronary artery score and yet after a angiogram, they find no blockage?
Great question: An angiogram is showing plaque buildup that is impacting blood flow within the lumen of the vessel but before you have that happen you can get atherosclerotic buildup within the wall of the vessel that grows outward. This can be seen by CT but can appear very minimal on an angiogram. However if you have a CT with high calcium score I recommend medical therapy for coronary disease (statin, aspirin) ...Read more
What would cause a high (1100+) right coronary artery score and yet after an angiogram, they find no blockage?
What part of the heart would receive less blood if the were a blockage in the left main coronary artery?
Left main: Most of the blood to the left ventricle passes thru the left main. That is why it is such a serious lesion. ...Read more
What do you recommend if I had a heart angiogram with 70% blockage in my left main coronary artery. No stint. Dr afraid he would block. Why?
Bypass surgery: Everything is a balance between risk/benefit. Often with a > 50% left main blockage, a bypass surgery is the safest choice. Medical therapy alone carries a high risk of sudden death due to the severity of the blockage. A stent placement there, though relatively simple - might have a catastrophic outcome if any slight thing went wrong. A stent is indicated if surgery is higher than usual risk. ...Read more
Would left coronary artery blockage produce ischemia of left ventricle and right axis deviation on ekg?
Not easy: Even with state of the art technology at large cardiac centers its not 100%. Even with catheterization, ct scans etc its still not clear which plaque is vulnerable and could cause a future event. Alternative drs and homeopathic medications may have its place, but for a life threatening condition such as this I would stick to traditional investigations and treatment. ...Read more
My coronary arteries are highly calcified. Does this mean that there is blockage? Other than angiogram, is there a less invasive test to show block?
By decreasing oxygen: The heart muscle depends on oxygen supplied by the coronary arteries to effectively function. When the artery is narrowed it can decrease the supply of oxygen and decrease the force of the muscle contraction. The stroke volume is a measure of how much blood the heart forces out with each beat. ...Read moreSee 1 more doctor answer
Invasive and non: Coronary blockage is defined as enough narrowing to cause symptoms, or to show up on a stress test. Stress tests look for signs of reduced heart muscle oxygen supply (e.g. Ekg changes during exercise, weak heart squeezing on echo, or nuclear perfusion defects). Angiography ("cardiac cath") is invasive, injecting dye into the arteries to image blockages, and stents can be inserted at the same time. ...Read moreSee 1 more doctor answer
