What does the precursory of acute myocardial infarction have

summary

Myocardial infarction is a disease with high incidence rate in life. It is also very terrible, especially acute myocardial infarction. It is very important to know the signs of acute myocardial infarction to find out the disease in time. Let's introduce the symptoms of acute myocardial infarction.

What does the precursory of acute myocardial infarction have

Pain: myocardial infarction precursor is the most prominent symptom of the disease. Most of the attacks have no obvious inducement, and often occur at a quiet time. The location and nature of the pain are the same as angina pectoris, but the pain is severe and lasts for a long time, for several hours or even days. Nitroglycerin is ineffective. Patients are often restless, sweating, scared or dying. A few patients may have no pain, shock or acute pulmonary edema at the onset.

Shock: 20% of patients may be accompanied by shock, mostly in a few hours to a week after onset. The patient's complexion was pale, restless, skin wet and cold, pulse was weak, blood pressure decreased less than 10.7kpa (80mmHg), and even fainted. If the patient only has the blood pressure to drop but does not have other performance, is called the hypotension condition. The main causes of shock are as follows: the cardiac muscle is seriously damaged and the left ventricular output is sharply reduced (cardiogenic shock); secondly, severe chest pain causes neuroreflex peripheral vasodilation; in addition, there are factors of insufficient blood volume caused by vomiting, sweating and insufficient intake.

Systemic symptoms: fever, tachycardia, leukocytosis and erythrocyte sedimentation. This is mainly caused by the absorption of tissue necrosis, usually in 1-2 days after infarction, body temperature is generally about 38 ℃, rarely more than 39 ℃, lasting about a week. Acute myocardial infarction (AMI) is a serious manifestation of coronary heart disease (CHD). The mortality of AMI is the highest in 24 hours after the onset of AMI. About 1 / 3-1 / 2 of AMI patients died before hospitalization. If we can find the premonitory symptoms of infarction early and deal with them, we can at least avoid the occurrence of infarction or reduce the infarct size.

matters needing attention

Patients with myocardial infarction should pay attention not to be emotional, not to be overworked, avoid smoking and drinking spicy food, develop good living habits and eating habits in daily life.
