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 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

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

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

My doctor told me I have 70% right coronary artery blockage. How did he measure the percentage of blockage?

Estimate: In general this is performed by comparing the size of the normal coronary artery to the area of the blockage. Under some circumstances this can be performed electronically. ...Read more

Hi doctors, was just wondering what is anomalous right coronary artery?

Hi doctors, was just wondering what is anomalous right coronary artery?

See below: An anomalous right coronary artery is one that is in a different location from its usual anatomic position. It can be different in two ways: 1) where it comes off of the aorta, 2) how it gets to the parts of the heart it is supposed to supply. This can be a benign condition that's nothing to worry about, but its important to followup with your doctor to check if the location of the artery is safe. ...Read more

What happens if your posterior descending arterial branch of the right coronary artery diffuse proximal 60 to 80%?

What happens if your posterior descending arterial branch of the right coronary artery diffuse proximal 60 to 80%?

Depends: Many people walk around with significant blockages without knowledge or harm. If the person described has angina or evidence of ischemia on testing, a percutaneous intervention should be considered. Otherwise, forget it - but treat the underlying arteriosclerosis: statin, aspirin, Mediterranean Diet, exercise, ideal body weight, no smoking, good BP control. ...Read more

I have 3 bare metal stents in my right coronary artery. How often should these be checked by a cardiologist and how is the check done?

Based on symptoms: Scar tissue can occur around the stent. You will feel the same type of symptoms the you had prior to the stent. Your cardiologist can determine what type of testing you need to assess that. If no symptoms we usually perform a stress test every 2 to 3 years. ...Read more

Can a thrombosis of right coronary artery just lie there dormant not doing anything or nor causing harm?

Can a thrombosis of right coronary artery just lie there dormant not doing anything or nor causing harm?

No: A thrombosis, or blood clot, does not "lie dormant". A thrombosis of the RCA would develop rather suddenly as a biochemical response to a cholesterol-based, calcium-coated plaque that "cracks". Just as when skin is cut, platelet blood cells and other chemicals come together to "heal" the break in the plaque by creating a thrombosis (clot) that can then block blood flow to cause a heart attack. ...Read more

Soft plaques at the proximal right coronary artery causing 30% luminal (phenobarbital) stenosis. What does thid mean?

Plaques: It means you have plaque in your coronary artery not obstructing flow a lot. It means aggressive diet, exercise, not smoking, BP control, lipid control, diabetes control all should be done to minimize progression of the plaque. Aspirin is also a good idea. ...Read more

Can an abnormal right coronary artery lead to any problems? What if you have symptoms during exercise such as chest pain/shoulder pain?

Possibly: If the right coronary artery arises from the pulmonary artery instead of the aorta, the blood flowing through it is low on oxygen, and can cause cardiac symptoms. This almost always presents in infants and children. In later life, coronary artery problems are due to atherosclerosis, and the symptoms are typically angina. If you have any questions, see you primary physician or cardiologist. ...Read more

Situation specific: There's data that suggests in certain scenarios medical management is equivalent to interventions like stenting. But that's a blanket statement and the reality is, it's very situation specific. Best to talk it over with your trusted cardiologist. ...Read more

What's mean mild coronary artery disease involving the left anterior descending and the right coronary artery? It's something to worry? Heart attack?

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 more

Possible 70% block in right coronary artery told CT angiography has high rate of false positives? Scared to have a heart cath especially if artifact

Possible 70% block in right coronary artery told CT angiography has high rate of false positives? Scared to have a heart cath especially if artifact

Different test: This all depends on why you had the ct angiogram. Could consider a functional study eg nuclear stress test to determine if that blockage is severe enough to treat. Best would be to discuss your options with a cardiologist. ...Read more

Congestive heart failure I was diagnosed with CHF and a 80 percent block of the right coronary artery my ejection fraction is up to 55-60 from 25-30 I still get tired and short of breath not getting answers from my doctor could that be from the block any

Congestive heart failure I was diagnosed with CHF and a 80 percent block of the right coronary artery my ejection fraction is up to 55-60 from 25-30 I still get tired and short of breath not getting answers from my doctor could that be from the block any

That: That is great news that your ejection fraction (ef) has improved that much, as that is directly correlated with your overall long term prognosis. You clearly are still symptomatic though. If you find that your shortness of breath continues, it is certainly possible that the stenosis in your right coronary artery is the culprit, although without knowing more information it is hard to say definitively. My best advice to you is to find a physician that will answer your questions and communicate with you so that you may understand your care. Heart disease is complex and involves the interplay of many factors, and an excellent relationship with your cardiologist can be the most important one. ...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

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
