3 Main Arteries Of The Heart
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
Maybe, maybe not: At autopsy, I Often see right main coronary arteries that have probably been occluded for years and the person dies of something unrelated. ...Read more
My husbands 3 main arteries are severely damaged. He's had a few heart attacks in the past and now he wants to have bypass surgery done. Can he travel.
Not right now.: I'm not confident that he should be traveling in this context. ...Read more
I have congestive heart failure my doctor says I hav one and three fourths arteries blocked and put me on medication and won't do anything else what would you recomend?
What part of the heart would receive less blood if the were a blockage in the left main coronary artery?
Left main: Most of the blood to the left ventricle passes thru the left main. That is why it is such a serious lesion. ...Read more
My boyfriend went to the ER with blood filled lungs and a pressure build up by the main artery leading to his heart, what could it be?
What do you recommend if I had a heart angiogram with 70% blockage in my left main coronary artery. No stint. Dr afraid he would block. Why?
Bypass surgery: Everything is a balance between risk/benefit. Often with a > 50% left main blockage, a bypass surgery is the safest choice. Medical therapy alone carries a high risk of sudden death due to the severity of the blockage. A stent placement there, though relatively simple - might have a catastrophic outcome if any slight thing went wrong. A stent is indicated if surgery is higher than usual risk. ...Read more
How come I always have a fever? Low grade and high. I have a stent in main artery of heart and broke 27 bones. That was over 2 years ago
If the main right artery to the heart is 100% occluded by a blood clot, would this cause sudden death? If so would the patient feel any pain?
What is likelyhood of having heart attack or angina after angioplasty (balloon) & stent placed on main artery?
Angioplasty/stent: Heart attack is not necessarily prevented by angioplasty or stent. We do treat the underlying disease aggressively as well as dual anti platelet therapy to prevent stent thrombosis. If you smoke it negates much of the treatment. Most people do well after angioplasty and stenting. ...Read more
I was recently told that I have calcium developing in my main heart artery! What does that mean and what can I do? I had weight loss surgery 2 yrs ago
Marker: Calcium may be a marker of blockage developing. Best plan is to be followed by cardiologist who will assess all your risk factors and suggest ways to minimize risk of allowing coronary disease to progress. Will also allow creation of testing schedule to follow for ongoing evaluation. Also recommend looking into things you can do to lower your riskd on your own as well, like not smoking ...Read more
Yea: It is possible especially if there is some heart damage caused by the blockage. ...Read more
Can arteries of the heart clog if on a super healthy diet, no cholesterol, no smoking, and low blood pressure?
Symptoms?: If you have symptoms (angina or heart attack), you need to be under a doctor's care. For everyone concerned about arteriosclerosis: don't smoke, eat a Mediterranean Diet, keep BP under control, try to be optimal weight, exercise daily. If you're >65, have diabetes, or known blockage, take aspirin daily (at least 75 mg). ...Read more
Ensure blood supply: The question is a little vague but I will try to explain. The small arteries to the heart (the coronary arteries) are what supply blood to the hearyt to keep it pumping. The big artery from the heart supplies the systemic circulation. If the small arteries get blocked, then you have a heart attack and may die. Any surgical proceedure may put enough stress on the heart to have a heart attack. ...Read more
I am assuming you: Are talking about coronary artery disease in the form of an atheromatous plague occlusive disease. Also I am assuming you don't have a heart attack. If above is right, you are supposed to be under the care of a cardiologist now. Drug treatment, stress test, 2d echocardiogram, cardiac catheterization and evaluation for a possible revascularization procedure already possibly done. ...Read more
Not often: A ct angio may be a reasonable alternative. Sounds like the cath is being performed because it can be not because it needs to be. ...Read more
Cholesterol and time: Untreated high chol, high bp, and time usually are the big factors. Family hx also plays a key role. ...Read more
Forever: For the majority, they last forever. 5-10 % heal with an exuberant scar. That occurs even less often with a drug eluting stent. ...Read more
Is the hearts output in one beat the only thing that makes the BP what it is or could the pressure on the arteries be effected by something else?
Your question is interesting when I see that you have had a number of "sophisticated" cardiac tests.
Yes one heartbeat initiates circulation at a given pressure but a lot of disorders affect the VESSELS which require the heart to beat at a higher pressure.
Hope this helps!

Usually pain: A clogged artery in the heart prevents oxygen from being delivered to the heart muscle. This will cause pain especially when the heart is being stressed as during exercise or in cold weather. The pain is usually experienced as squeezing or pressure and can be present in the chest, neck, back, or arm. A person may also get sweaty and feel short of breath. ...Read more
Larger than normal: The aorta is the largest blood vessel carrying blood from the heart to elsewhere. Enlargement of vessel means a dilation (ballooning out as pictured here) to larger than it should be. It right next to the heart--aortic root, it can cause the valve to leak, and if severe it can cause much problem. Enlargement further down may burst, that causes serious problem too. Consult doc. Good luck. ...Read more
It depends: This really depends on the clinical circumstances. The heart has three main arteries that supply the heart blood. I have had patients who have blocked off two of the arteries and thus were living off one artery which formed collarterals, or "natural bypasses" to other areas of the heart. With medications and monitoring in my opinion it is possible to have a reasonable quality of life. ...Read more
Risk modification: I am assuming you have coronary artery disease and possibly an ischemic event. We are dealing with secondary prevention. Do not smoke, aggressive lipid modification with statins drugs (lower LDL less than 100 and less than 70 if dm and cad), diabetes treatment, BP less than 130/80, Aspirin 81mg a day, Plavix (clopidogrel) if CAD and revascularization done (pci/stent), weight control, physician manage exercise. ...Read more
