The common causes of cardiogenic shock are as follows: 1. Myocardial contractility decreases extremely, when large myocardial infarction, fulminant myocarditis or severe arrhythmia occurs, myocardial contractility decreases significantly. Because the myocardial cells have necrosis can not contract, and the heart can not contract and eject blood, there will be cardiogenic shock; 2, ventricular ejection disorders occur, resulting in cardiogenic shock. The door where the ventricle goes to pump blood to the blood vessels of the whole body is called the aortic valve, and the door inside the right ventricle to the lungs is called the pulmonary valve. When these two arterial valves become severely narrowed and the ventricle cannot eject blood, there is no blood in the body circulation, and cardiogenic shock will also occur. Conversely, the door between the atrium and the ventricle is called the mitral valve and tricuspid valve, and when it is severely incomplete, most of the blood returns to the atrium when the heart contracts, and is not able to shoot to the body circulation, cardiogenic shock will also occur. Ventricular filling disorder, that is, there is a layer of membrane outside the heart called pericardium, when the pericardium is filled, fluid, blood or tumor, the heart can not be diastolic, the ventricle can not fill, will also lead to ejection disorder; 3, atrial tumor, most of them are mucinous tumor, it obstructs the blood from the atria over to the heart ventricle, will also lead to cardiogenic shock.
