عنوان انگلیسی Left Atrial Volume Index as a Predicting Factor for the Severity of Acute Coronary Syndrome
چکیده انگلیسی مقاله Background: Coronary artery disease (CAD) is a predominant contributor to global mortality. The left atrial volume index (LAVI) is a recognized marker of chronic diastolic dysfunction and has been linked to unfavorable outcomes in patients with acute coronary syndrome (ACS). This study explored the association between echocardiographic parameters and the angiographic complexity of CAD in patients presenting with ACS.   Methods: This prospective cohort study enrolled 52 patients diagnosed with ACS who were treated with percutaneous coronary intervention. Each participant underwent a comprehensive echocardiographic evaluation, including measurement of LAVI, and coronary angiography with SYNTAX score calculation.   Results: The majority of patients (n = 52) were male (94.2%) with a mean age of 57.3 ± 9.0 years. Single-vessel disease was detected in 78.8%, and low SYNTAX scores (>22) in 86.5%. LAVI correlated positively with age (r = 0.333; P = 0.016), left anterior descending artery diameter (r = 0.840; P < 0.001), left atrial volume A2 (r = 0.904; P < 0.001), left atrial volume A4 (r = 0.913; P < 0.001), and SYNTAX categories (r = 0.337; P = 0.015). Two-vessel disease (adjusted odds ratio, 15.4 [95% CI, 1.4 to 165.3]; P = 0.024) and age greater than 68 years (AOR, 24.0 [95% CI, 1.2 to 489.6]; P = 0.039) independently predicted more severe CAD.   Conclusions: LAVI correlates with coronary complexity in ACS. Age and multivessel disease predict more severe CAD, supporting the prognostic value of echocardiographic assessment. (Iranian Heart Journal 2025; 26(4): 46-56)
