Design outcomes

Primary

MeasureTime frame
Correlation between Left Atrial (LA) deformation parameters [Peak Atrial Longitudinal Strain (PALS) & Peak Atrial Contraction Strain (PACS)] and postoperative atrial fibrillation (POAF) in patients undergoing coronary artery bypass grafting (CABG)Timepoint: Up to 7 days post-surgery or until discharge, whichever is earlier—

Secondary

MeasureTime frame
Correlation of LA deformation parameters (PALS & PACS) with the presence of hypertension and diabetes mellitus in patients undergoing CABGTimepoint: Preoperative data and intraoperative assessment;Comparison of demographic, clinical, and intraoperative variables (e.g., CPB time, AXC time) in patients with and without POAFTimepoint: Intraoperative period and up to 7 days post-surgery;Correlation of LA strain parameters with Doppler parameters and LV Global Longitudinal Strain (GLS)Timepoint: Preoperative transthoracic echocardiography;Correlation between LA deformation & early postoperative complications, including: 1.Acute kidney injury (AKIN criteria) 2.Sepsis (TLC, procalcitonin) 3.Stroke/neurocognitive dysfunction (GCS, MoCA) 4.Low cardiac output (VIS) 5.Prolonged mechanical ventilation/NIV requirement 6.Prolonged ICU stay 7.ICU mortalityTimepoint: Within 7 days postoperative period or ICU stay duration—
