Effects of Different Heart Positions During Off-pump Coronary Artery Bypass Surgery on Serum Ischemia Modified Albumin Level and Cardiac Output

Objectives:We aimed to evaluate the potential effects of heart positioning during off-pump CABG (OPCAB) without a cardiac stabilizer device on serum levels of ischemia modified albumin (IMA) and cardiac output (CO). Materials and Methods:This was a prospective study in which consecutive patients who underwent isolated OPCAB were included.Data including electrocardiography and intraarterial hemodynamic monitoring parameters were recorded.Arterial pressure waveform was analyzed.CO was measured for circumflex coronary artery (Cx), diagonal coronary
