Association of LAAWV values with the BNP
Heart failure (HF) and left ventricular dysfunction can arise from various causes, including ischemic heart disease, different types of arrhythmias, and cardiomyopathy. In such cases, the levels of NT pro-BNP tend to increase. Framingham offspring cohort study investigated the utility of BNP in predicting heart failure outcomes. In the context of atrial fibrillation (AF), M Lungtungan et al. demonstrated a significant correlation between left atrial appendage velocity (LAAV) and NT pro-BNP levels in patients with non-valvular AF. In our study, we found that the level of NT pro-BNP was significantly higher in patients with worse left ventricular systolic function, and it also strongly correlated with reduced left atrial appendage wall velocity (LAAW velocity). The correlation between NT pro-BNP levels and LAAW velocity highlights the potential of LAAW velocity as an additional parameter for evaluating cardiac function in such patients.
