What are some of the consequences of coronary artery blockage?

Chest pain: There may be no symptoms but if the blockage is severe enough, chest pain, especially on exertion, can occur. Also heart attack or even sudden death. Therefore, good to see your doctor and be advised of your risk factors and ways to prevent coronary artery blockage. ...Read more

Artery (Definition)

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 are some of the treatments available for coronary artery blockage?

What are some of the treatments available for coronary artery blockage?

Treatment of CAD: Treatment falls into 3 categories. Medical therapy, angioplasty, and coronary bypass surgery. Medical therapy with Aspirin and cholesterol-lowering medications along with other medications usually forms the basis of treatment with angioplasty (stents) and bypass surgery reserved for those patients who do not respond fully to medical therapy. ...Read more

What are the causes of coronary artery blockage?

What are the causes of coronary artery blockage?

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 more

What tests are used to diagnose coronary artery blockage?

What tests are used to diagnose coronary artery blockage?

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 more

Does the ornish program apply to coronary artery blockage?

Does the ornish program apply to coronary artery blockage?

Yes: The ornish program of life style changes is certainly a good idea for someone who already had coronary artery blockage. It involves lifestyle changes such as diet, exercise, stopping smoking, and stress management. It is not a replacement for treating your disease with medications where indicated. ...Read more

What tests are available to diagnose coronary artery blockage?

What tests are available to diagnose coronary artery blockage?

Several: If a cardiologist suspects coronary artery blockage the first step will be a very complete history. A nuclear stress test is a common diagnostic test and cardiac ct angiograms are becoming more common. The next step is usually a diagnostic cardiac catheterizaiton. Also since approximately 80% of coronary artery disease, cad, patients have peripheral vascular disease, pvd, that will need eval to. ...Read more

How can coronary artery blockage be diagnosed by alternative medical practitioners?

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

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

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?

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?

Angioangiogram: Usually calcification and coronary artery blockages go hand in hand. You have already had the gold standard test-the angiogram. There are less invasive tests e.g. Coronary ct scan, which usually shows calcium but not as sensitive or specfic as a angiogram. ...Read more

Can you explain the metabolic mechanisms that take place during coronary artery blockage?

Can you explain the metabolic mechanisms that take place during coronary artery blockage?

Yes: A coronary artery blockage of myocardial infarction (heart attack) occurs when an atherosclerotic plaque ruptures losing its fibrous cap and lipid core thereby exposing type-4 collagen which is very prothrombotic (clot promoting). It is the blood clot forming at the ruptured plaque that shuts down the coronary artery. ...Read more

What could cause a high (1100+) right coronary artery score and yet after a angiogram, they find no blockage?

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

Calcicardiogram: The study you refer to scores calcium in vessel walls. This does not always correlate with coronary obstruction. It does imply the disease process is present. ...Read more

How do doctors test for coronary artery blockage?

How do doctors test for coronary artery blockage?

Usually stress tests: Stress tests are used to see if an artery has severe blockage in it, which prevents adequate blood flow to the heart muscle to meet its energy needs. If abnormal, cardiac cath (i.e. "angiogram) is often needed to invasively image the arteries and see the extent of the problem. ...Read more

Yes: Yes, a coronary angiogram is the most widely used test to look for blockages in the arteries of the heart and to decide the best treatment option (medication only vs stent vs bypass surgery). ...Read more

Coronary artery is the name given to the blood vessels that supply the myocardium. The word coronary was coined by the first anatomists that noticed that if you remove all muscle from the heart the remaining vessels resemble the shape of a corona or crown. ...Read more
