Third degree symptoms of heart failure?
summary
Heart failure refers to cardiac insufficiency. Under the condition of normal venous return, cardiac output is reduced due to primary heart damage, which can not meet the metabolic needs of the body. For its treatment, we must first find out the cause, and then actively eliminate the cause, so as to reduce the cardiac load. Generally, heart failure also has grades. Each grade represents the severity of the disease. There are four grades. The higher the grade, the more dangerous it is. That is to say, the third grade of heart failure belongs to the dangerous period. However, if it is treated, the disease can be controlled. Let's take a look at the third grade symptoms of heart failure?
Third degree symptoms of heart failure?
Total heart failure: manifested as bilateral heart failure, both ventricles can be damaged at the same time, can also develop from one side to the other side. Right heart failure: refers to the heart failure caused by the lesion involving the right ventricle and (or) right atrium, or the right ventricular pressure overload caused by the pulmonary vascular pressure, mainly manifested as systemic venous and organ congestion.
High output heart failure: when heart failure occurs in most cardiovascular diseases, cardiac output is lower than normal, so it is called low output heart failure. But some diseases, such as hyperthyroidism, anemia, beriberi and so on, have increased metabolism, dilated peripheral arterioles, decreased peripheral resistance and increased blood circulation, which increase the cardiac load and lead to heart failure. At this time, cardiac output is significantly higher than normal, even if heart failure occurs, cardiac output can still be normal or higher than normal. This is high output heart failure.
Pump failure: a term recently proposed, mainly used to describe acute myocardial infarction complicated with acute left ventricular failure, especially cardiogenic shock. In fact, according to the characteristics of the heart pump, all heart failure caused by myocardial lesions or damage, resulting in reduced myocardial contractility, belongs to the category of pump failure.
matters needing attention
For a patient with heart failure, diuretics and angiotensin converting enzyme inhibitors are often used. If the patient's condition is serious or heart failure symptoms are obvious in the early stage, digitalis Zhengxing inotropic drugs should be combined. When the use of the above three kinds of drugs, the disease can be controlled and stable, can be added β Receptor blockers to improve long-term symptoms and prognosis of patients.
