Variable HR (95% CI) P
Mechanical prosthesis 1.90 (0.69–5.18) 0.213
BMI ≥ 30 kg/m 2 4.41 (1.66–11.8) 0.003
COPD 2.87 (1.19–6.91) 0.019
MV > 5 days 5.34 (1.13–25.4) 0.035
Mitral regurgitation 2.56 (1.05–6.25) 0.040
SAH 2.31 (0.96–5.56) 0.062
Ischemia time 1.01 (0.99–1.02) 0.131
Diabetes mellitus 1.74 (0.48–6.36) 0.404
Hospitalization time 1.01 (0.98–1.03) 0.740
Rheumatic fever 1.15 (0.41–3.27) 0.790
RF 1.28 (0.14–11.4) 0.828
  1. HR: hazard ratio; 95% CI = 95% confidence interval; BMI = body mass index; SAH = systemic arterial hypertension; COPD = chronic obstructive pulmonary disease; MV = mechanical ventilation; RF = renal failure.
  2. Significant results (p<0.005) are highlighted in bold.
