Conclusion
We determined that in patients of heart failure with reduced ejection fraction (both ischemic and non-ischemic), reduced LAAW velocity was significantly associated with impaired LV systolic function, as depicted by left ventricular ejection fraction (LVEF), inversely correlated with left ventricular global longitudinal strain (LV GLS) and serum biomarker NT pro-BNP. LAAW velocity is also significantly correlated with estimated elevated left ventricular filling pressure (E/e’) as well. However, we did not find any significant correlation of LAAWV with age and gender in patients with heart failure with reduced ejection fraction. In comparison to established echocardiographic and biochemical parameters, LAAW velocity emerges as a valuable and reliable parameter in assessing cardiac function in this specific group of patient population.
