Do Post-Operative Electrocardiographic (ECG) Changes Indicate any Underlying Graft Problem after CABG? Correlation of Early Post-Operative ECG Changes with CT Coronary Angiography (CTCA)

Abstract

Purpose: Identifying occult and potentially life-threatening problems in the absence of hemodynamic instability and elevation of cardiac markers has always remained a diagnostic challenge in patients after coronary artery bypass graft (CABG). A study to identify these threats by comparing ECG changes to CTCA changes is thus essential to isolate and evaluate highrisk cases.
