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.?

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

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

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?

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

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

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

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

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

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 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

If a body had a thrombosis of right coronary artery at post-mortem, is that a sign of a DEFINITE heart attack?

If a body had a thrombosis of right coronary artery at post-mortem, is that a sign of a DEFINITE heart attack?

See below: If the thrombus involved the right main coronary artery, that would be a sign of "heart attack". The person may have died suddenly, without usual symptoms of heart attack. ...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

Coronary Artery (Definition)

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
