Left Atrial Volume Index: As a Predictor of Early In-Hospital Major Adverse Cardiovascular Events in Acute Coronary Syndrome

Abstract

Introduction: Raised Left Atrial Volume Index (LAVI) is considered as an important predictor of poor outcome in patients having acute coronary syndrome. Aim: To study LAVI as a predictor of early in-hospital major cardiovascular events in acute coronary syndrome. Materials and Methods: Prospective observational study was carried out in 84 patients admitted in ICU of tertiary care hospital with a diagnosis of acute coronary syndrome. Clinical, electrocardiogram, 2D echocardiographic, laboratory tests and outcome of patients having acute coronary syndrome during hospital stay were assessed. Biplane method of discs was used to measure Left Atrial Volume (LAV). LAVI was calculated by dividing LAV and body surface area. Out of 84 patients, 26 patients having LAVI >32 mL/m2 were grouped into group A and 58 patients having LAVI 0.05. Mean ejection fraction was 46.7% in patients with LAVI 32 mL/m2 (group A) which was significant, p-value <0.001. Conclusion: Routine measurement of LAV and calculation of LAVI in patients with acute coronary syndrome is necessary to prevent major adverse cardiovascular events.
