pain originating in the heart muscle, I called angina. It occurs when blood vessels to the heart (coronary arteries) become partially blocked with fatty plaques caused by atherosclerosis (heart disease). The blood flow is sufficient only when the heart is at rest, but during the activity, when the heart can increase 75 to 190 beats per minute, the heart muscle can not get enough blood in it and causes mild to severe pain. That is why angina is brought on by exercise, but it will subside when the activity stops and the person rests. Angina will become worse over time and fewer actions will cause pain. If the angina worsens and suddenly you have symptoms even while at rest, the cause could be blocked arteries resulting in heart attacks. If this occurs, seek immediate medical attention. Angina is not easy to diagnose from symptoms alone, as well as other conditions such as indigestion, showing similar signs.
Signs and symptoms of
About the pain can be mild or severe the pain is often described as heavy, crushing, tightness, and suffocation the pain originates from the center of the chest, may radiate to the neck and down the arms. Typically, the left arm. Shortness of breath Perspiration on the
there are no specific tests for angina, but your doctor will probably start by asking three simple questions. What causes anxiety? What do you feel like? What helps alleviate the pain? Doctor also eventually be suspected angina if other cardiovascular risk factors such as - cigarette smoking, family history of heart attack, high blood pressure and cholesterol, age and dijabetesa.Liječnik will perform a physical examination on patients paying special attention to the heart and any abnormal sounds or beats.
Routine tests include an electrocardiogram (ECG), blood pressure measurement, blood and urine tests and chest X-ray.Liječnik may require ECG in a patient walks on a treadmill (bicycle), and hooked to a machine that records the electrical activity of the heart. The level of exercise is slowly increased until the patient feels pain and has been a change in the EKG pattern. Further tests may include a coronary angiogram. This implies a fine tube inserted into his heart through the arteries in preponi.Posebna color then inserted into the artery clearly shows any narrowing (blocked) arteries on X-ray images.
angina responds well to treatment lijekovima.Najčešći medications used to treat angina are as follows:
Nitrates - These medicines come as fast-acting sprays or tablets under the tongue to relieve pain during an attack of angina. Long-acting tablets taken daily to reduce the need for sprays.
of the Beta-blockers - These pills reduce the burden by allowing the heart to beat more slowly and less forcefully than usual. These tablets prevent pain and slow down gradually worsening angina.
O Calcium antagonists - helps arteries dilate allowing more blood to flow through them. They lower blood pressure, reduce the workload of the heart to prevent pain.
The standard treatment is low dose aspirin to prevent more from building atheroma in the arteries of the heart.
After the artery has become blocked or narrowed by plaque and atheroma, there are two levels of intervention needed to restore blood flow to the heart mišić.Intervencije chosen will depend on how hard the artery is blocked or narrowed. 1) angioplasty - This procedure is done only when the arteries are not completely blokiran.Novčanom fine tube (catheter) is inserted into the heart. At the top of the tube is a small balloon, which is then inflated and deflated several times to squash the plaque and widen the artery. This procedure is performed under local anesthesia and is performed on an outpatient basis. 2) bypass surgery - This procedure is performed only if the artery completely blocked or very uske.Novi direction of blood flow is performed using the bypass graft. For bypass graft, surgeons have two options -. They either use an existing artery which is located in the chest or the use of the leg veins removed from the
Sometimes a person can have up to four blocks for the bypass. Bypass surgery is performed under local anesthesia and can take three to five hours to complete the operation. Today it has become one of the most commonly performed surgical procedures.
