Study on the Application of Cardiac Ultrasound in the Diagnosis and Evaluation of Cardiac Function in Patients with Chronic Heart Failure

The objective of this study was to examine the potential of cardiac ultrasound in the diagnosis and evaluation of cardiac function in patients with chronic heart failure. This study aimed to address the high morbidity and mortality associated with chronic heart failure. In terms of research methods, the latest progress in cardiac ultrasound technology and its application in the diagnosis of chronic heart failure was reviewed. The role of cardiac ultrasound in the evaluation of cardiac structure (such as ventricular size and wall thickness), valvular disease detection and cardiac function (such as ejection fraction measurement) was analyzed. Important results indicate that echocardiography, a non-invasive, dynamic detection method, can accurately assess cardiac structure and function in patients with chronic heart failure, providing comprehensive information for diagnosis and reference for optimization of treatment options. Cardiac ultrasound has significant application value in the diagnosis and cardiac function evaluation of patients with chronic heart failure, which is beneficial for improving diagnostic accuracy and prognosis.
