What is the cause of acute myocardial infarction complicated with cardiogenic shock?

The main causes of acute myocardial infarction complicated with cardiogenic shock include large myocardial infarction area, arrhythmia, hypovolemia and other factors. The high-risk groups include the elderly, patients with underlying diseases and female patients. Supportive treatment should be taken according to the causes. The main causes of acute myocardial infarction complicated with cardiogenic shock include: 1. Large myocardial infarction area: Widespread myocardial infarction in the left ventricle leads to significant decrease in myocardial contractility and significant decrease in cardiac output. 2. Arrhythmia: Tachyarrhythmias such as ventricular fibrillation, ventricular tachycardia, and bradyarrhythmias such as atrioventricular block can lead to decreased cardiac output. 3. Hypovolemia: Such as vomiting, diarrhea, a lot of sweating, etc. lead to insufficient blood volume, effective circulation blood volume reduced.4.Other: such as infection, acidosis, electrolyte disorder, etc., can also affect myocardial contractility, leading to cardiogenic shock. In addition, for the elderly, there are underlying diseases (such as hypertension, diabetes, hyperlipidemia, etc.), as well as female patients, acute myocardial infarction complicated with cardiogenic shock is relatively high risk. In terms of treatment, in addition to the treatment for the cause, active supportive treatment, such as blood volume supplementation, application of vasoactive drugs, correction of arrhythmia, etc., is required to maintain the patient's vital signs and vital organ functions. In conclusion, acute myocardial infarction complicated with cardiogenic shock is a serious cardiovascular emergency, requiring timely diagnosis and treatment. For high-risk groups, preventive measures should be actively taken, such as control of blood pressure, blood glucose, blood lipids, etc., to reduce the risk of disease.
