circumflex artery blockage

Answers

1 Answers

How serious is a circumflex artery blockage that is 90%? Would this likely be fatal and if so, how long before one would have that result on average?

Coronary artery

Artery
High grade circumflex disease coul be the cause of angina or infarction. It could be fatal but less likely than LAD disease. If well treated you could live a long time with that disease and something else could get you. Smoke and don't work on your condition and chances in infarction are excellent.

Middle LAD & circumflex artery are 100% blocked. Blockages, while severe, short in length.Both arteries receive collateral. Can Angioplasty/stent help?

Yes if symptoms

Artery
From ischemia are not responsive to medical therapy

Smaller targets can be a challenge. BUT we can do Coronary artery by bass grafting CABG for most.

Have relatively short 100% blockage in mid LAD &100% Posterolateral branch of Circumflex artery (both relatively small targets).Will Stent help or ris?

stent

Artery
there are technical factors in deciding whether stenting is possible and physiologic predictions of whether successful stenting will yield benefit. your doctors including interventional cardiologist are best to advise you regarding your specific situation

Can you do angioplasty stent on restively short 100% blockage in mid LAD and 100 % Posterolateral branch of Circumflex artery & both relatively small.

Generally yes

Artery
The real question is do they need to be done. An artery that has been closed for some time (CTO), is usually no longer threatening to you. In some cases, with unacceptable symptoms despite appropriate meds, an attempt at opening the vessels may be considered. Ask an interventional cardiologist with experience in doing CTOs to review your Cath.

How much artery blockage causes PVD pain?

Everyone's different

Blood
The pain of PAD is from tissue (muscles, skin, nerves, etc) not getting enough blood. An elite athlete might have symptoms from a single 50% plaque. A sedentary person might not notice a complete blockage or multiple partial blockages. Rest pain is usually from severe plaques at multiple levels. In general, the body compensates for artery plaques for a long time before pain occurs.

What are the causes of coronary artery blockage?

Several

Blood
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.

Dr. Alon Gitig answered:

How do doctors test for coronary artery blockage?

Usually stress tests

Artery
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.

Does angiogram show heart coronary arteries blockage?

Yes
