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.
