What is a surgery you can have when your coronary artery is blocked?
Arterial coronary artery bypass surgery is what is done to cure clogged arteries to the heart.
What does triple by-pass mean?
Triple bypass surgery is a type of coronary artery bypass surgery, and is a surgical procedure performed to relieve angina (or vessel blockage due) and reduce the risk of death from coronary artery disease. Arteries or veins from elsewhere in the patient's body are grafted to the coronary arteries to bypass atherosclerotic narrowings and improve the blood supply to the coronary circulation supplying the myocardium (heart muscle).The terms single bypass, double bypass, triple bypass, quadruple bypass and quintuple bypass refer to the number of coronary arteries bypassed in the procedure. In other words, a double bypass means two coronary arteries are bypassed (e.g. the left anterior descending (LAD) coronary artery and right coronary artery (RCA)); a triple bypass means three vessels are bypassed (e.g. LAD, RCA, left circumflex artery (LCX)), and so on. Less commonly more than four coronary arteries may be bypassed.
What does the apex of your heart do I had a stress test done and am getting no blood at all to my apex do you know what causes this?
I'm really not sure, but it could be due to a coronary artery block where your right coronary artery isn't getting the necessary blood from you aorta...But that is just a guess...I would def. go to a cardiologist
What is the cure to heart attack?
Getting rid of the fat that blocks the coronary artery and cuts off blood supply to the heart. Nowadays this is done using stents, which are like tiny little tunnels that keep the artery clear and allows the blood to flow.
Coronary artery balloon angioplasty - series?
Normal anatomyThe coronary arteries supply blood to the heart muscle. The right coronary artery supplies both the left and the right heart; the left coronary artery supplies the left heart.IndicationFat and cholesterol accumulates on the inside of arteries (atherosclerosis). The small arteries of the heart muscle (the coronary arteries) can be narrowed or blocked by this accumulation. If the narrowing is small, percutaneous transluminal coronary angioplasty, or PTCA for short, may be the course for treatment. PTCA is a minimally invasive procedure to open up blocked coronary arteries, allowing blood to circulate unobstructed to the heart muscle. The indications for PTCA are:Persistent chest pain (angina)Blockage of only one or two coronary arteriesProcedure, part 1While the patient is awake and pain-free (local anesthesia), a catheter is inserted into an artery at the top of the leg (the femoral artery). The procedure begins with the doctor injecting some local anesthesia into the groin area and putting a needle into the femoral artery (the blood vessel that runs from the heart down the leg). Once the needle is inserted, a guide wire is placed through the needle, into the blood vessel. Following this step, the guide wire is left in the blood vessel and the needle is removed. A large needle called an introducer is then placed over the guide wire and the guide wire is removed.Procedure, part 2Next, a diagnostic catheter, which is a long narrow tube, is advanced through the introducer over a .035"guidewire, into the blood vessel. This catheter is then guided to the aorta and the guidewire is removed. Once the catheter is placed in the opening or ostium of one of the coronary arteries, the doctor injects dye and takes a series of X-rays (film of the images).Procedure, part 3The first catheter is exchanged out over the guidewire for a guiding catheter and the guidewire is removed. A smaller guidewire is advanced across the blocked section of the coronary artery and a balloon -tipped tube is positioned so the balloon part of the tube is beside the blockage. The balloon is then inflated for a few seconds to compress the blockage against the artery wall. Then the balloon is deflated. The doctor may repeat this a few times, each time pumping up the balloon a little more to widen the passage for the blood to flow through. This treatment may be repeated at each blocked site in the coronary arteries.Procedure, part 4A device called a stent may be placed. A stent is a latticed, metal scaffold that is placed within the coronary artery to keep the vessel open.Procedure, part 5Once the catheter has been positioned at the coronary artery origin, contrast media is injected and a series of X-rays (film) are taken to check for any change in the arteries. Following this, the catheter is removed and the procedure is completed.Aftercare, part 1This procedure can greatly improve the blood flow through the coronary arteries and to the heart tissue in about 90% of patients and may eliminate the need for coronary artery bypass surgery. The outcome is relief from chest pain symptoms and an improved exercise capacity. In 2 out of 3 cases, the procedure is considered successful with complete elimination of the narrowing or blockage. This procedure treats the condition but does not eliminate the cause and recurrences happen in 1 out of 3 to 5 cases. Patients should consider diet, exercise, and stress reduction measures. If adequate widening of the narrowing is not accomplished, heart surgery (coronary artery bypass graft surgery, also called a CABG) may be recommended.Aftercare, part 2Immediately after the procedure, a ten-pound sandbag may be placed over the femoral artery puncture site in the leg and remain there for 6 hours. This is done to help the artery heal.Reviewed ByReview Date: 05/23/2011Michael A.

What happens during a bypass operation?
During a bypass operation, a surgeon creates a new pathway for blood flow when an artery is partially or completely blocked. This is usually done by using a healthy blood vessel from another part of the body to redirect blood around the blockage, restoring proper blood flow to the heart muscle. This procedure can help alleviate symptoms of coronary artery disease and reduce the risk of a heart attack.
What is the purpose of PTCA?
Percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure used to open blocked or narrowed coronary arteries to improve blood flow to the heart muscle. It is commonly performed to relieve symptoms of angina, prevent heart attacks, and improve overall heart function. PTCA can also be done as a part of a treatment plan for a heart attack or to reduce the need for coronary artery bypass surgery.
What research has been done on carnitine?
angina (heart pain due to decreased oxygen because of coronary artery disease). Two studies using L-carnitine, and one using L-propionylcarnitine, have demonstrated a reduction in symptoms of this condition.
What research has been done on HMG-CoA inhibitors?
In 2003, researchers reported that people with heart failure but no coronary artery disease received benefits after only 14 weeks of statin therapy. In addition, some research has connected the drugs to reduced risk for depression and dementia.
Heart bypass surgery - series?
Normal anatomyThe heart muscle is supplied blood through the coronary arteries. The left coronary artery supplies blood to the left ventricle. The right coronary artery supplies blood to the right ventricle.IndicationsCoronary artery bypass grafting (CABG) or heart bypass surgery is recommended when one or more coronary arteries are seriously blocked and blood supply to the heart muscle is insufficient. Several tests are done to identify the cause of the chest pain (angina), such as blood tests and x-ray studies (angiograms).Procedure, part 1Although the heart itself is not "opened", the heart-lung bypass machine is used to re-route the blood from the heart while the surgery is being done to provide adequate circulation to the brain and other vital organs.Procedure, part 2Coronary bypass surgery is an open heart surgery (the chest is opened, but not the heart itself). It is done through an opening through the breast bone. While one surgeon is working on the chest, another surgeon works on taking a length of vein (saphenous vein) for the bypass through a long incision along the inside of the lower leg. The vein is sewn in above and below the blockage in the coronary artery. Alternatively, an artery from the interior aspect of the chest wall (internal mammary artery), or the arm (radial artery) is used.Procedure, part 3In many cases, more than one coronary artery must be bypassed, and both the internal mammary and radial arteries and the saphenous vein are used to perform the bypasses.AftercareAfter the operation, the patient will spend 7 to 10 days in the hospital, the first 1 to 3 days in an intensive-care unit (ICU). Chest tubes will be in place for the first 2 to 3 days to drain any residual blood and fluid from around the heart. Heart functions will be monitored. The full benefits from the operation may not be ascertained until 3 to 6 months after surgery. Sexual activity may be resumed 3 to 4 weeks after surgery. All activities that do not cause fatigue are permitted, but the patient must not strain the healing chest bone (sternum).Reviewed ByReview Date: 05/06/2011Shabir Bhimji MD, PhD, Specializing in General Surgery, Cardiothoracic and Vascular Surgery, Midland, TX.
