Key result
Pre-existing CAD is linked to altered LVEF and cardiac output in CABG patients.
Why the study?
The impact of pre-existing coronary artery disease on cardiac function in patients undergoing aortobifemoral bypass grafting for abdominal aortic occlusive disease was unclear.
Observational (n=34)
No takes yet. Share an insight, caveat, or question.
May support selective invasive monitoring in symptomatic CAD patients; Level 5 data leaves open routine preoperative radionuclide angiography utility.
Commin et al. (1984) conducted an observational in Abdominal aortic occlusive disease (n=34). Pre-existing coronary artery disease vs. No symptoms of coronary artery disease was evaluated on Left ventricular ejection fraction and cardiac output. Among 34 patients undergoing bypass grafting, pre-existing coronary artery disease was associated with significantly altered left ventricular ejection fraction and cardiac output.
