The cause of acute left heart failure in the elderly?

summary

Heart failure is clinically divided into left heart failure and right heart failure. Therefore, it is also very important for us to properly increase our understanding of this disease, because it is generally believed that heart failure is a disease, It is necessary to actively cooperate with clinical treatment measures to better control the development of the disease. At the same time, we should pay attention to the protection of our human heart, which is conducive to better prevention of disease, which is also necessary.

The cause of acute left heart failure in the elderly?

1. Acute extensive anterior myocardial infarction, primary dilated cardiomyopathy and so on, which are related to coronary heart disease. Elderly patients with acute left ventricular overload have valvular diseases such as mitral insufficiency and aortic insufficiency. The mechanical complications of acute myocardial infarction in coronary heart disease include rupture of papillary muscle infarction and perforation of ventricular septum.

2. There are also acute left ventricular overload hypertension, especially acute or malignant hypertension, primary obstructive cardiomyopathy, severe aortic stenosis, excessive use of vasoconstrictors, etc. Left atrial failure is mainly seen in severe mitral stenosis, occasionally in left atrial myxoma or huge thrombus blocking mitral valve orifice.

3. Severe arrhythmia, tachyarrhythmia (such as malignant ventricular arrhythmia) or significant bradycardia. Heart disease, patent ductus arteriosus, ventricular septal defect and atrial defect have a large number of left to right shunt, which are more common in children than in the elderly. Others: such as low cardiac output after surgery, infection, etc.

matters needing attention

The common causes of acute left heart failure in the elderly are: 1) infection: respiratory tract infection is the most common, accounting for 68% - 75%, and the others are urinary tract infection and intestinal tract infection. Acute left heart failure can be easily induced by infection, which can increase metabolism, heart rate and cardiac load.
