Dilating coronary

Dilating coronary
About the disease and its
.definition: heal or expand the coronary vessels is a type of treatment options designed to open narrowed coronary arteries that nourish the heart. Can cause coronary artery disease incidence of angina, can also lead to heart attacks. During the process of expanding the coronary vessels, being open arteries that have become too narrow to allow the passage of adequate blood because of the accumulation of remnant cholesterol (plaque). The doctor inserts a Qttarfa arteries, usually in the groin area and then pushes this Alqttarany up to the coronary arteries. Upon arrival to the place of the blockage, can be used as a tool resembling a balloon be present at the end of the catheter, in order to compress the fatty accumulations on the walls of the artery. Anatomy The heart is the most important muscle in the body. The main function of the heart is pumping blood to the lungs and to the rest of the body. Since the heart is composed of living tissue, it is in need of blood, like the rest of the body. And also the heart to pump blood to itself through the many blood vessels go directly to the heart muscle. Know these vessels as "the coronary arteries." Symptoms and causes accumulate residue of cholesterol in the coronary arteries constitute "plaque" lead to a narrowing of the arteries. You can not pass the narrowed arteries sufficient amount of blood. This is what leads to decreased blood flow, which in turn could lead to a heart attack. If decreased blood flow to a certain extent due to the accumulation of cholesterol remnants, the heart is no longer able to keep pace with the effort being done by human. If worse case, or if the arteries are blocked, the heart can be infected with the damage. Cause coronary artery disease myocardial injury in the first place. Some patients feel pressure or angina pain or tightening in the chest or neck or arm or jaw. In the absence of treatment, the disease of the coronary arteries can lead to a heart attack can be fatal. The process of dilating coronary treatment is used to open arteries closed. After the success of this process, improves blood flow in the vessel. And receives the necessary amount of blood the heart to him, and retracts the symptoms, and decreases the risk of heart attack. Quick treatment is surgery to expand the coronary arteries and one of the many possible treatments in order to deal with the problem of the accumulation of fatty substances in the blood vessels own heart. Is not none of these treatments to cure this situation;, it is possible to accumulate in the fat of new blood vessels if the patient does not comply. with preventive measures. Doctors may prescribe drugs for people with coronary artery disease. Some medicines may help to make the blood vessels larger or more spacious. It may also help to relieve the symptoms of medicines and reduce the need of oxygen to the heart. Of alternative therapies also perform coronary bypass surgery. In this open-heart surgery, being the use of a blood vessel is taken from the patient's body in order to bypass or making "Ex" place beyond the blockage in the artery. At that point, the blood flows to the heart surpassing the blocked artery. Your doctor can discuss treatment options with the patient and suggest what suits him. Surgery could be asked of the doctor patient not to eat any food or drink for several hours before the operation. If the date of the operation scheduled in the morning, this usually means not eating any food or drink after midnight the night before. During the process of expansion of the coronary arteries, the doctor determines the starting position. in the narrowed artery, and then open it by introducing the catheter to the exact location. There are many procedures in order to open a blocked artery. This is what we will discuss later. This is not valid for the whole procedure all patients. The physician determines the appropriate action according to the patient's condition. Can make the process of expansion of the coronary arteries is the patient's stay in the hospital. This means that the patient be able to go home after the procedure is finished. But sometimes the patient to remain in the hospital an extra day or more. The doctor will explain to the patient how long it is expected to be spent by the patient in the hospital, depending on his health and on other factors as well. The patient is awake during the procedure in this process. Due to the lack of any real pain. The doctor asks the patient to lie on the X-ray table. During the operation, carried out continuous monitoring of heart rate, blood pressure, and vital signs. Before the start of the operation, conducted haircut the groin area and cleanse the skin. And then being drugged by using a local anesthetic. After the catheter is inserted through the skin into an. artery in the patient's leg. Then pushes the catheter until it reaches the coronary arteries. Sometimes, depending on the doctor's preferences and the state of the arteries of the patient, the catheter can be introduced in the large artery located under the armpit or in the upper arm instead of the groin area or intertrigenous. At that point, pigmentary material is being injected into the arteries and X-ray pictures are taken. And the patient to remain completely quiet during filming in order to allow access to good pictures and clear. When you reach the blockage, the doctor decides whether to open it possible using a balloon or other means. Called the way in which a balloon is used as the "expansion of the artery balloon." Be connected by the end of the balloon catheter is being inserted until the area artery blockage by the user in the process of angiography. Then being inflatable balloon and then eject it and then blowing air several times until the pressure of being the fatty accumulations on the wall of the artery. This allows the passage of more blood through the artery. When it is ejected from the air balloon and dragging it to the outside of the body. In the process of expanding the artery, the doctor may decide to put a network of stainless steel.in the position of the blockage in order to maintain the artery open. This is called the body-shaped tubular as the "pillar". If you use a stent, they prove at the end of the catheter is then placed in a blockage. In some cases, can be .used is the mainstay of the balloon, in order to open a blocked artery
