Interruption of blood supply – порушення кровопостачання

Arterial embolism is a sudden interruption of blood flow to an organ or body part due to a clot.

Occlusion of the coronary artery – закупорка коронарної артерії

Occlusion of the coronary artery which carries blood containing oxygen and other nutrients essential to the normal functioning of the heart muscle may be partial or complete.

Physical exertion – фізичне навантаження

Anybody who engages regularly in intense physical exertions is strongly advised to have routine echocardiographic screening.

Chest pain – біль у грудній клітині

Chest pain is discomfort or pain along the front of your body between the neck and upper abdomen. Any organ or tissue in the chest can be the source of pain including heart, lungs, esophagus, muscles, ribs, tendons, or nerves.

Silent myocardial infarction – безсимптномний інфаркт міокарду

A heart attack does not always have obvious symptoms, such as pain in the chest, shortness of breath and cold sweats. In fact, a heart attack can actually happen any symptoms. It is called a silent heart attack, or medically referred to as silent ischemia (lack of oxygen) to the heart muscle.

Echocardiography – ехокардіографія

Echocardiography is a painless test that uses sound waves to create moving pictures of the heart. The pictures show the size and shape of your heart. They also show how well your heart's chambers and valves are working.

MYOCARDIAL INFARCTION

Myocardial infarction commonly known as a heart attack is the interruption of blood supply to a part of the heart causing heart cells to die. This is most commonly due to occlusion of a coronary artery after the rupture of an atherosclerotic plaque. The resulting ischaemia if left untreated for a sufficient period of time can cause damage or death of heart muscle tissue.

Heart attack rates are higher in intense exertions, such as psychological stress or physical exertion. Acute severe infection, such as pneumonia, can trigger myocardial infarction. Important risk factors are previous cardiovascular disease, older age, tobacco smoking, diabetes, high blood pressure, obesity, chronic kidney disease, heart failure, excessive alcohol consumption.

The onset of symptoms in myocardial infarction is usually gradual, over several minutes. Chest pain is the most common symptom of acute myocardial infarction and is often described as a sensation of tightness, pressure, or squeezing. Chest pain due to ischaemia of the heart muscle is termed angina pectoris. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and epigastrium.

Other symptoms include weakness, nausea, vomiting, and palpitation. Loss of consciousness and sudden death can occur in myocardial infarction. Women may experience fewer typical symptoms than men, most commonly shortness of breath, weakness, a feeling of indigestion, and fatigue. Approximately one quarter of all myocardial infarctions is “silent”, without chest pain or other symptoms.

Among the diagnostic tests available to detect heart muscle damage are an electrocardiogram (ECG), echocardiography, and various blood tests. Immediate treatment for suspected acute myocardial infarction includes oxygen, aspirin, and sublingual nitroglycerin. Most cases are treated with thrombolysis or percutaneous coronary intervention. Heart attacks are the leading cause of death for both men and women worldwide. The risk of a recurrent myocardial infarction decreases with blood pressure control and lifestyle changes, regular exercise, a certain diet for patients with heart disease, and limitation of smoking and alcohol intake.
