Implication

May support angiography to lower mortality in post-CABG ischemia; leaves open randomized confirmation of benefit.

Key Points

To evaluate the diagnostic utility and clinical impact of early postoperative angiography in patients who develop signs of perioperative myocardial ischemia following coronary artery bypass grafting.
Retrospective cohort analysis of 2,052 consecutive patients undergoing coronary artery bypass grafting over a 12-month period at a single institution.
Identified 131 patients (6.4%) meeting standardized criteria for perioperative ischemia based on elevated CK/CK-MB ratios (>10%), ST-segment changes, ventricular arrhythmias, or refractory hemodynamic deterioration.
Assigned patients to early diagnostic angiography (Group A, n=108) or immediate salvage re-operation without imaging due to severe hemodynamic collapse (Group B, n=23).
Early angiography in Group A identified graft failure or technical complications in 58.3% of evaluated patients (63/108), resulting in 34 surgical re-operations and 9 early angioplasties.
Group B surgical exploration without angiography confirmed graft occlusion in 43.5% (10/23) and incorrect anastomoses in 21.7% (5/23), while 17.4% (4/23) had normal operative morphology.
Thirty-day mortality was significantly lower in Group A at 9.3% (10/108) compared to 39.1% (9/23) in Group B.

Structured PICO

Does immediate angiography identify correctable graft failure and guide management in patients with perioperative ischemia after CABG?

Population

131 patients with defined clinical and laboratory criteria of perioperative myocardial ischemia after coronary artery bypass grafting (from a total cohort of 2052 patients)

Intervention

Immediate angiography (n=108)

Comparator

Immediate re-operation due to severely compromised hemodynamics without prior angiography (n=23)

Outcome

Angiographic/operative findings and 30-day mortalityhard clinical

Early angiography in patients with perioperative ischemia after CABG frequently identifies correctable graft failure and guides appropriate reintervention.
