Implication

Supports selective re-angiography in stable early post-CABG ischemia; leaves open optimal management in unstable patients.

Structured PICO

What are the angiographic findings and clinical outcomes of acute re-angiography versus immediate re-operation in patients with suspected myocardial ischaemia early after CABG?

P
Population
71 patients with suspected myocardial ischaemia early after isolated coronary artery bypass grafting (CABG), identified from a total of 2003 patients operated between 1990 and 1995.
I
Intervention
Acute coronary angiography followed by re-operation if indicated (performed in stable patients, n=59).
C
Comparator
Immediate re-operation without preceding angiography (performed in haemodynamically severely compromised patients, n=12).
O
Outcome
Angiographic findings of graft failure or incomplete re-vascularization, and 30-day mortality.hard clinical

Acute re-angiography is feasible and identifies graft failure in the majority of patients with early post-CABG ischemia, allowing for targeted re-operation with relatively low mortality.
