Myocardial infarction is a heart disease caused by an acute disorder of blood circulation. This is a rather dangerous disease that is often fatal.
The heart muscle ceases to receive oxygen and nutrients from the blood, as a result of which ischemic necrosis develops. Symptoms of a heart attack can be severe, burning pains that radiate to the scapula, left arm or sternum and are accompanied by feelings of anxiety, fear and shortness of breath.
Causes of myocardial infarction
Most often, myocardial infarction develops in men over 50 years of age. This is due to their lifestyle, as well as the development of atherosclerosis. Every year, a heart attack takes away almost 35% of patients with its acute course.
- the main reason for the development of acute myocardial infarction. You can often find a combination of atherosclerosis with thrombosis. Also, the development of the disease can contribute to arterial hypertension, diabetes mellitus, abuse of nicotine and alcohol, and stress. Most often, myocardial infarction is diagnosed in the left ventricle of the heart.
Myocardial infarction symptoms
Many patients may experience a condition called pre-infarction. During this period, patients develop progressive angina pectoris, which cannot be stopped by drugs.
But in most cases, myocardial infarction occurs acutely, with painful sensations in the chest, which radiate under the scapula, in the left arm, and the jaw. The pains can be bursting, burning, pressing, or sharp. The pain becomes more intense in the volume of the affected area.
Most often, pains are observed from several minutes to several hours and proceed in waves, then subside, then appear again. Nitroglycerin in this case does not relieve pain. The patient feels general weakness, fear and excitement.
In atypical cases, the patient may experience cold sweat, pallor of the skin, increased blood pressure, which can sharply drop to a critical level, often there is arrhythmia or tachycardia.
