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?

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

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

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.

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?

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?

Serious: Left dominance means the circumflex artery supplies the major back portion of the heart rather than the right artery So occlusion of this artery compromise a large area of heart muscle that can lead to death by fatal arrhythmia or by heart failure ...Read more

Will a 3-D MRI show blockage in the proximal and distal circumflex arteries; also, the level of RCA disease? Murrell

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

How much artery blockage causes pvd pain?

How much artery blockage causes pvd pain?

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

If a 70-year-old suffered an artery blockage, what is their chance of survival?

If a 70-year-old suffered an artery blockage, what is their chance of survival?

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

How do I have all the other arteries check to see if any plaque is building up or blockage?

How do I have all the other arteries check to see if any plaque is building up or blockage?

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?

Could it happen that a fall causes a plaque build up in an artery to break off and cause a complete blockage?

No: A mechanical fall does not cause arterial plaque to rupture and cause an embolism. However, if someone experienced an embolism to the brain, lung, or leg it could cause a sudden loss of strength and that could cause a fall. ...Read more

Hi doctors, how long does plaque in the arteries take to progress into a complete blockage, when minimal now. 60 y/o male?

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.com/9x3n594 ...Read more

Should i be concerned 85-90% blockage in their neck artery?
