Because of circulatory disorders of the heart, as well as any lesion necrosis in cardiac muscle may occur myocardial infarction. This can happen if the coronary artery is blocked by a blood clot, spasseruetsya this artery or narrowing its lumen due to any other reasons. From what the affected artery, and which area of the heart muscle died, depends on the severity of myocardial infarction. In order to prevent myocardial infarction, regular ultrasound of the heart.
Characterized by myocardial infarction sudden pricking pain behind the chest, feeling the strong squeezing in the chest, suffocation. Typically, the pain passes over the left shoulder and left arm, and sometimes the fingers. The victim appears the fear of death, anxiety. His pale skin is clammy and cold sweat. Sometimes the attack may be accompanied by nausea, vomiting, and abdominal pain. Pulse in a patient with frequent and irregular.
Myocardial infarction can be small or large, which covers the wall of the heart muscle. If the affected heart muscle, the reaction can be sharp. In this regard, it is important to quickly call an ambulance. In addition, it is necessary to monitor the patient's condition, in order to avoid complications.
Myocardial infarction can lead to heart rhythm disturbances, which poses a serious threat to life. To restore the rhythm can only medicines and doctors. Because the heart muscle is affected, it lost its contractility, and this causes difficulty in pumping blood to the heart, a sharp decrease of blood ejection, reducing the so-called cardiac output of the heart. I.e. heart significantly less ejected blood, and this leads to insufficient supply of organs with oxygen contained in the blood. As a result of circulatory failure occurs cardiogenic shock. Therefore, the patient cannot change the position of his body.
In myocardial infarction affected the left half of the heart, so the left ventricle is not able to push all the blood that enters it. Due to the fact that slows down the blood flow in the lungs accumulates a large volume of blood. Due to the fact that a stasis of blood pressure in the blood vessels of the lungs increases, and in light through the walls of blood vessels enters the blood plasma. And this leads to edema of the lungs. In such a situation, the person providing first aid, it is impossible to take any specific action. During extensive myocardial infarction can break your heart muscle, and this becomes a cause of sudden death.
During first aid ease the breathing of the patient, for which undo loose clothing or to remove it altogether. Apply a moist hot compress on the arms and hands of the patient. Lay the patient so that the upper body was raised to reduce the workload of the heart. It is important to monitor vital functions of the body. In the case of cardiac arrest and cessation of breathing have to do chest compressions and artificial respiration. Talk with the patient, try to calm him down.
It is important when providing care not to give the patient the provisions of the "jackknife" in order not to overload the heart to eject blood out of him. His torso should be slightly raised, and for this purpose under the back of the patient it is necessary to enclose jacket or a rolled blanket.
In humans, myocardial infarction may occur several times. Usually, after the first case, a doctor appointed nitroglycerin. So a person who renders first aid, should ask the patient about the presence of the drug.
