Echocardiographic parameters in patients with and without hypotension during dialysis.
Introduction: Hypotension during dialysis is a common complication of hemodialysis and is associated with increased patient mortality and morbidity. Intradialytic hypotension is a decrease in systolic BP ≥20 mm Hg or a reduction in mean arterial pressure by 10 mm Hg along with clinical events and the need for correction. This study compares cardiac function, using transthoracic echocardiography with strain modality in patients with intradialytic hypotension with those without hypotension during dialysis. ⋯ Global Longitudinal Strain (GLS) was significantly lower in the intradialytic hypotension group (-14.17 ± 2.79 versus -18.99 ± 2.25, P value < 0.001). The receiver operator characteristics (ROC) curve point-coordinates that GLS of -16.85 and lower (more positive) has 83% sensitivity and 87% specificity for intradialytic hypotension. Conclusion: The echocardiographic assessment could be used as a tool for the prediction of hypotension during dialysis.
