Elevated preoperative neutrophil/lymphocyte ratio as a predictor of increased long-term survival in minimal invasive coronary artery bypass surgery compared to sternotomy

Table 5 Multivariate logistic regression models for all-cause mortality among patients with preoperative neutrophil lymphocyte ratio ≥3

Variable	Odd ratio	95% confidence interval	p Value
Model A
MICS vs. Sternotomy CABG	0.44	0.24–0.78	0.005
Internal mammary artery used	0.39	0.17–0.89	0.02
Postoperative new onset atrial fibrillation	1.72	1.01–2.93	0.04
Beta blockers on discharge	0.57	0.30–1.09	0.09
In-hospital clopidogrel	1.56	0.92–2.63	0.09
Model B
MICS vs. Sternotomy CABG	0.50	0.28–0.90	0.02
Age (per year)	1.08	1.05–1.11	<0.001
Preoperative renal failure on dialysis	10.05	3.46–29.19	<0.001
Internal mammary artery used	0.48	0.20–1.12	0.08

Model A included history of prior coronary angioplasty, MICS vs. sternotomy CABG, postoperative new onset atrial fibrillation, use of internal mammary artery, use of cardiopulmonary bypass, clopidogrel on discharge and in-hospital, coumadin on discharge, beta blockers on discharge.
Model B included age, gender, family history of coronary artery disease, history of renal dialysis, statin on discharge, coumadin on discharge, use of internal mammary artery, MICS vs. sternotomy CABG and postoperative new onset atrial fibrillation.
MICS minimal invasive cardiac surgery (thoracotomy), CABG coronary artery bypass graft.
