RIGHT VENTRICULAR FUNCTION PARAMETERS ON ECHOCARDIOGRAPHY IN PATIENTS HAVING HEART FAILURE WITH REDUCED EJECTION FRACTION
Main Article Content
Abstract
Background: Heart failure is one of the leading causes of death and hospitalization in cardiovascular patients. Right ventricular dysfunction is commonly observed in patients having heart failure with reduced ejection fraction. Accurate assessment of right ventricular function is beneficial for risk evaluation and helps physicians choose optimal treatment methods to improve the outcome. Objectives: This study was conducted to describe right ventricular dysfunction by echocardiography in patients having heart failure with reduced ejection fraction. Methods: A descriptive cross-sectional study was conducted on 110 heart failure patients having reduced ejection fraction at the Cardiology Department of Cho Ray Hospital. Echocardiography was used to assess the prevalence of right ventricular dysfunction through three parameters: TAPSE, RVFAC, and RVs’. Results: The echocardiographic measurements showed that the mean values of TAPSE, RVFAC, and RVs’ were 17.4 ± 2.8 mm, 30.2 ± 13.2%, and 0.10 ± 0.03 m/s, respectively. The rates of abnormal TAPSE, RVFAC, and RVs’ were 35.5%, 64.6%, and 48.2%, respectively. Conclusion: Right ventricular dysfunction was significantly present in our study and requires further attention. The ability to detect right ventricular dysfunction varies considerably depending on the echocardiographic parameter used
