BACKGROUND Several echocardiographic methods have been proposed to rapidly and routinely analyse Right Ventricular (RV) performance in various clinical settings. Among these, TAPSE, Sa and RV FAC are simple, rapid and feasible methods which were correlated with the standard methods of RV functional evaluation.
BACKGROUNDRight Ventricular (RV) function has been shown to be a major determinant of clinical outcome and consequently should be considered during clinical management and treatment. Thus, the need for diagnosis of RV dysfunction is evident. MATERIALS AND METHODS RESULTSIncidence of RV dysfunction in study population by TAPSE<1.5 cm was 44 (22%). 23 (29.1%) patients with Inferior wall MI had RV dysfunction and 21 (17.3%) patients with anterior wall MI had RV dysfunction. Out of 200 patients with acute myocardial infarction, 22% (44/200) had RV dysfunction. Mean age of patients in RV dysfunction group was 57.4 ± 11.3 years and of patients in no-RV dysfunction (Normal RV function) group was 52.3 ± 11.2 years (p =0.008). 15.9% (7/44) patients in RV dysfunction group had past history of Coronary artery disease compared to 5.8% (9/156) in normal RV function group (p=0.02). CONCLUSIONNearly one fourth of patients with Acute ST-Elevation Myocardial Infarction had right ventricular dysfunction. LV dysfunction contributes significantly to RV dysfunction in acute myocardial infarction more so in anterior wall MI. KEYWORDS BACKGROUNDRight Ventricular (RV) function may be impaired either by primary right-sided heart disease, or secondary to left-sided cardiomyopathy or valvular heart disease. In addition, it should be considered that RV dysfunction may affect left ventricular (LV) function, not only by limiting LV preload, but also by adverse systolic and diastolic interaction via the interventricular septum and the pericardium (ventricular interdependence). Moreover, RV function has been shown to be a major determinant of clinical outcome and consequently should be considered during clinical management and treatment. Thus, the need for diagnosis of RV dysfunction is evident.
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.
