Blockage In The Right Coronary Artery
Recently I had angioplasty for the second time and I still have a 45% blockage in my right coronary artery. Now what?
Discuss with: Your cardiologist who knows your medical history and exam and is in the best position to answer this question for you. ...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 I ride a roller coaster 3 years after having a heart attack due to blockage of the right coronary artery and getting stents implanted?
Enjoy ride: Hope you are not doing the tallest and fastest roller coaster. ...Read more
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?
My doctor told me I have 70% right coronary artery blockage. How did he measure the percentage of blockage?
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%?
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
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
If the blockage is in the right then right. If in the left left.
Sometimes both and difficult. ...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
I have unstable angina and a 100% blocked right coronary artery. Had an angeoplasy done and the doctor did nothing after but said may just use meds?
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
I am 61 years old, I have undergone angioplasty (single stent) for right coronary artery 3 years ago. Can I exercise daily for 30 minutes on a treadmill?
If a body had a thrombosis of right coronary artery at post-mortem, is that a sign of a DEFINITE heart attack?
Life expectancy of a 59-year-old male, type 1 diabetic after receiving a right coronary artery stent, while having the other side of heart scarred.?
Difficult to sat: Risk assessment over 5 years as described is well validated. Predicting lifespan is challenging. Aggressive management of risk factors in close coordination with your doctors and specialists is crucial. ...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?
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
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
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
Coronary arteries: Please rephrase this questions it doesn't make any sense in its current form. I'd be glad to answer if I can understand what you are asking :-). ...Read more
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?
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
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
