Popis: Background: Atrioventricular plane displacement (AVPD) reflects global left ventricular function despite left ventricular asymmetry as it is determined in four different regions of left ventricle. The limitations of agreement between left ventricular ejection fraction (LVEF) and AVPD are not close enough for these two measurements to be interchangeable. There is reason to question whether AVPD provides the same information as LVEF. Aim: The aim of this study was to assess relations of AVPD with LVEF and clinical findings in patients left ventricular failure (LVF). Materials and Methods: One hundred patients aged ≥18 years with coronary artery disease admitted with LVF were included in this cross sectional study. Echocardiographic examination was performed. Left ventricular AVPD was evaluated by M mode, in the four and two chamber views. Primary aim was to compare AVPD with LVEF by echocardiography. Secondary outcome measures were comparison of AVPD with traditional risk factors, clinical features, and pro-B-type natriuretic peptide (BNP) levels. Comparison of qualitative and quantitative variables was done by using Chi-square test/Fisher's exact test and unpaired t-test. Pearson's correlation was used to study correlation. Results: Mean AVPD was significantly lower in patients with severe LVEF as compared to mild, and moderate LVEF. Correlation of AVPD with LVEF, pro BNP, septum, anterior, lateral and posterior wall hypokinesia was 0.895. 0.841, 0.898, 0.911, 0.893 and 0.907 respectively. Conclusions: Mean AVPD was significantly lower in patients with severe LVEF. Mean AVPD positively correlated with LVEF, pro BNP, septum, anterior, lateral and posterior wall hypokinesia.
