OBJECTIVE: To evaluate pulmonary hypertension (PH) in asymptomatic thalassemic patients using echocardiographic right ventricular (RV) parameters. MATERIAL AND METHODS: This is a cross-sectional study. We assessed 32 ambulatory asymptomatic thalassemia cases both clinically and using echocardiographic parameters. PH was observed in 13 (40%) patients. RESULTS: difference in RV echocardiographic parameter S' (p = 0.03), E' (p = 0.016) and Tricuspid valve (TV) E/E' (p = 0.04). Other RV echocardiographic parameters such as the right ventricular ejection fraction (RVEF), tricuspid annular plane systolic excursion CONCLUSION: PH was found in 40% of asymptomatic thalassemic patients. Of all echocardiographic RV parameters, we found that the tissue doppler imaging (TDI): S', E' and TV E/E' are the best tools for screening. This tool detects early RV dysfunction in asymptomatic thalassemias with PH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
