The Effect of Echocardiography Based on Lipid Nano Contrast Agent on Cardiology Patients with Heart Failure and Atrial Fibrillation.

This paper discusses the effect and evaluation of echocardiography based on lipid nano contrast agent on patients with heart failure and atrial fibrillation in cardiology department, providing reference for clinical diagnosis and treatment. Fifty two patients with diastolic heart failure diagnosed by echocardiography were selected for routine echocardiographic examination after optimizing the drug treatment scheme, and then the patients underwent treadmill exercise test and stress echocardiography evaluation. The results of conventional echocardiography and stress echocardiography after treatment were compared with those before treatment, and the clinical parameters and biochemical indexes before and after treatment were compared. Results after treatment, the clinical symptoms of the patients improved, the level of NT proBNP in the N-terminal forebrain decreased significantly, and the exercise tolerance increased significantly. Compared with the conventional echocardiography before and after treatment, the left ratio and e' value of stress echocardiography after treatment increased significantly, while E/e' decreased significantly. There was no significant difference in the indexes of general echocardiography before and after treatment. After treatment, positively correlated with the ratio of peak a to peak E. The results show that the sensitivity of stress echocardiography to evaluate ischemic diastolic heart failure has been improved, and some indexes have clinical significance. Compared with conventional echocardiography, it can effectively evaluate the therapeutic effect of drugs.
