Impact of severe left ventricular dysfunction on in-hospital and mid-term outcomes of Chinese patients undergoing first isolated off-pump coronary artery bypass grafting

Table 4 Risk-adjusted effect of grouping on in-hospital outcomes

Events	Severe group	Impaired group OR (95%CI), p value	Normal group OR (95%CI), p value
In-hospital mortality	1.0	0.38 (0.18-0.92), p = 0.04	0.27 (0.10-0.67), p = 0.008
New onset of MI	1.0	0.66 (0.28-1.87), p = 0.38	0.45 (0.18-1.39), p = 0.08
Low cardiac output	1.0	0.39 (0.26-0.71), p = 0.002	0.21 (0.16-0.35), p < 0.001
Reoperation for bleeding	1.0	0.71 (0.23-2.62), p = 0.48	0.55 (0.18-1.92), p = 0.24
Prolonged ventilation	1.0	0.41 (0.20-0.88), p = 0.03	0.17 (0.09-0.31), p = 0.001
Stroke	1.0	0.96 (0.41-2.76), p = 0.84	0.87 (0.38-2.36), p = 0.81
Acute renal failure	1.0	0.51 (0.21-1.67), p = 0.29	0.42 (0.18-1.35), p = 0.09
DSWI	1.0	0.52 (0.21-1.75), p = 0.19	0.42 (0.17-1.36), p = 0.09
Red blood cell transfusion	1.0	0.67 (0.42-1.21), p = 0.11	0.69 (0.44-1.28), p = 0.14

MI, myocardial infarction; DSWI, deep sternal wound infection
Adjusted confounders included age, gender, recent smoking, diabetes, hypertension, hyperlipaemia, chronic obstructive pulmonary disease, renal dysfunction, prior cerebro-vascular accident, history of percutaneous cardiac intervention, history of myocardial infarction, congestive heart failure, triple-vessel coronary artery disease, left main coronary artery disease, and number of grafts
