Abstract

Aim: Left atrial volume index (LAVI) is correlated with the risk of atrial fibrillation, cerebrovascular events, congestive heart failure, and death. In this study, we aim to reveal the relationship between the SYNTAX score I and LAVI.
Methods: A total of 176 (128 male, 48 female) patients who underwent elective coronary angiography with the diagnosis of stable angina pectoris (SAP) were included in the study. The biplane disc method was used to calculate the LAVI in transthoracic echocardiography.
Results: Based on the LAVI mean level, the patients were split into two groups: Group 1 (LAVI <27.8 mL/m2) and Group 2 (LAVI >27.8 mL/m2). We found that body mass index (OR: 1.13495% CI 1.014-1.268; p = 0.028), left ventricular ejection fraction (OR: 0.938 95% CI 0.889-0.991; p = 0.022), age (OR: 3.849, 95% CI 1.430-10.15 p 0.008), SYNTAX Score I (OR: 1.072 95% CI 1.009-1.140; p = 0.024) and left ventricular mass index (OR: 1.048 95% CI 1.015-1.082; p = 0.004) independently predicted LAVI increase.
Conclusion: Regardless of the anatomy and function of the left ventricle, the SYNTAX Score I is linked to an increase in LAVI. LAVI is a simple and practical echocardiographic parameter, and it may play a role in risk assessment before the procedure in patients undergoing elective coronary angiography due to SAP.
