ABSTRACT

Objective: The aim of the study was to determine usefulness of isovolumic acceleration to assess right ventricular function in patients with pulmonary hypertension. Background: Right ventricular dysfunction is a powerful predictor of adverse outcomes in patients with pulmonary hypertension. Although isovolumic acceleration is a sensitive and relatively load-independent parameter for ventricular contractile function, it has not been widely used. So, the aim of the study was to determine the usefulness of isovolumic acceleration in assessing right ventricular function in patients with pulmonary hypertension. Methods: A single center, prospective observational case-control study has been carried out for the period of one year at Osmania general hospital (Hyderabad). A total of 32 consecutive patients with pulmonary hypertension and 32 age matched healthy controls were recruited in the study as per the inclusion and exclusion criteria of the study. Receiver operator characteristic curves were used to study sensitivity, specificity, positive predictive value, negative predictive values as well as pearson’s correlation coefficients. Results: The results of the study showed that isovolumic acceleration has good significant correlation with right ventricular fractional area change (r = 0.554, p = 0.001) and tissue Doppler myocardial performance index (r = -0.599, p = 0.001) whereas a lesser but significant correlation was observed with tricuspid annular plane systolic excursion (r = 0.327, p = 0.034). Isovolumic acceleration showed higher specificity (81%) and positive predictive value (88%) in diagnosing right ventricular dysfunction in pulmonary hypertension compared to tricuspid annular systolic excursion velocity and tissue Doppler myocardial performance index parameters. Therefore isovolumic acceleration may be a better variable for diagnosing right ventricular dysfunction. Conclusions: Isovolumic acceleration is a sensitive and specific marker of right ventricular function in pulmonary hypertension.
