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.
