Circumflex Artery Blockage
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: 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. ...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
Middle LAD & circumflex artery are 100% blocked. Blockages, while severe, short in length. Both arteries receive collateral. Can angioplasty/stent help?
When 100% blockage in mid LAD and 100 % posterolateral branch of circumflex artery & both relatively small. What that means. Would it hinder bcag.
Does not mean: CABG not possible.Get a more detailed answer ›
Have relatively short 100% blockage in mid LAD &100% posterolateral branch of circumflex artery (both relatively small targets).Will stent help or ris?
Stent: 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. ...Read more
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: 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. ...Read more
How serious is an occlusion of the left circumflex artery if your heart is left-side dominant? Would an MI from that likely be fatal?
I have 100% blocked circumflex artery and all other arteries are reassuringly normal with heart muscle intact, what are the complications in my case?
See below: Keep the BP and the lipids to ideal levels. Do not smoke, so u would not have any complications! ...Read more
Will a 3-D MRI show blockage in the proximal and distal circumflex arteries; also, the level of RCA disease? Murrell
MRI or MRA? CTA angi: The question's somewhat vague. Are you asking about 3-D vs. 2-D MRI? Or MRI vs. MRA (Magnetic resonance angiogram)? MRI can show changes in tissue that are effects of arterial blockage. The actual arteries themselves are seen by MRA. The size of artery blocked determines whether or not it can be seen. More proximal = larger artery = easier to see blockage. The heart moves, & MRI pics often blurry. ...Read more
Everyone's different: 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. ...Read more
Depends. . .: Where is blockage? In other words, which artery is blocked? Heart? Brain? Legs? Lungs? Penis? Arterial blockage in heart could cause angina (chest pain) or even heart attack if abrupt. In brain, we call this a stroke. In legs, it's peripheral arterial/vascular disease. In lungs, it's pulmonary embolism (very dangerous & deadly). In penis, it's erectile dysfunction. Chance of survival varies. . . ...Read more
Various modalities: There are non-invasive tests to look for blockages such as stress echocardiography (stress test w/ultrasound imaging), nuclear myocardial perfusion imaging (nuclear medicine imaging), cardiac ct and MRI (mri is still investigational for coronary anatomy). Gold standard examination requires invasive cardiac catheterization with dye injected into the arteries (or ultrasound) and imaged. ...Read more
Could it happen that a fall causes a plaque build up in an artery to break off and cause a complete blockage?
Hi doctors, how long does plaque in the arteries take to progress into a complete blockage, when minimal now. 60 y/o male?
Many factors affect: This is highly variable. The natural course is for it to slowly progress but the odds are it will never progress to complete blockage and it could stay stable or even regress and disappear. Many factors determine how quickly it progresses or regresses: your blood pressure, diet, activity level, stress, exposure to toxins, genetics etc. See http://tinyurl. Com/axtab4d and http://tinyurl.

Vascular surgeon: That's a high grade blockage and puts one at high risk for a stroke. A vascular surgeon is best qualified to follow, treat and advise a patient with such a high grade blockage. ...Read more
Risk: If an artery is 25-50% narrowed, you would generally not have any symptoms except under extreme exercise. However, the fact that it is partially blocked implies that you are at risk for progression - either gradual due the risk factors that cause the partial narrowing or suddenly when platelets stick to the area and cause complete blockage. ...Read more
90%: Is the usual amount of blockage that produces "claudication." it varies quite a bit, though; some people don't notice anything until they have 100% blockage, others start to notice problems at 50%. The more you ask of your legs, the earlier you'll notice it. ...Read more
What are some ways doctors measure cardio health? How do they know if there is any blockage in arteries?
Recently I had a blockage in artery and they tried to stent me, it was not a sucess. They want me to go back for a roto rooter procedure. Complicati?
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
Location?: The best test for detecting blockage in your arteries depends on the location of the blockage. Ultrasound can be used to detect blockage in the carotid (neck) and leg arteries, for example. ...Read more

See a retina special: Yes. Lack of blood flow due to a retinal artery occlusion can cause severe loss of vision from damage to the retina. A central retinal artery occlusion is worse than a branch retinal artery occlusion. There are no good treatments, but a systemic workup looking for an embolic source is required (carotid ultrasound, echocardiogram). A rarer cause is giant cell arteritis. ...Read more
Not necessarily.: Chronic mesenteric ischemia is a condition where the "guts" do not have enough circulation in order to digest food properly. This causes pain after eating and can lead to weight loss. It can be a very serious condition that can require a procedure or surgery. However, the body is amazingly redundant. Most people have to experience complete or near complete blockage in two of the three main arteries to experience these symptoms. ...Read more
Somewhat unclear: Blockages in the carotid artery of a certain severity may increase one's risk of stroke. For those carotid arteries without a blockage, some physicians measure the intima (the inner-most lining of the artery) and derive a value called the imt, or intimal-medial thickness. It's supposed to help us determine severity of atherosclerosis, but this is somewhat controversial. ...Read more
