Abstract
Chronic heart failure (CHF) is a group of clinical syndromes caused by changes in myocardial structure and function caused by any reason, leading to ventricular filling and ejection disorders. It is the final stage of the development of various cardiovascular diseases. It is a progressive disease. Once it starts, even if there is no new myocardial damage, the clinic is still in a stable stage, and it can still continue to develop on its own. This article uses the comprehensive parameters of echocardiography to evaluate the overall heart function of patients with chronic heart failure, and evaluates the treatment effect of patients with chronic heart failure. A total of 160 patients with chronic heart failure were studied, including 80 cases in the follow-up group, 40 cases in the non-follow-up group, and 40 cases in the normal control group. The heart failure ultrasound index composed of the comprehensive parameters of echocardiography was used to measure brain natriureric pepride (BNP), and the heart function was graded. The results showed that when the heart failure ultrasound index value >3, the diagnosis of symptomatic chronic heart failure had a sensitivity of 94.7%, a specificity of 94.6%, a positive predictive value of 97.8%, and a negative predictive value of 80.6%. The heart failure ultrasound index was positively correlated with plasma BNP and NYHA heart function (respectively 0.68, 0.73). After 6 months of observation, the ultrasound index of heart failure in the follow-up group decreased significantly before and after treatment. The experimental results show that the heart failure ultrasound index can be used to guide the treatment of patients with chronic heart failure, evaluate the treatment effect, and evaluate the prognosis. Appropriate health education and standardized medication can improve the treatment effect of chronic heart failure and improve the quality of life of patients.
