Table 7 Predictors of reoperation by Cox regression analysis

From: Comparison of clinical outcomes in patients undergoing mitral valve replacement with mechanical or biological substitutes: a 20 years cohort

Variable HR (95% CI) p
Biological prosthesis 1.89 (0.94-3.82) 0.075
Male gender 2.54 (1.20-5.35) 0.015
Valve prosthesis diameter 0.82 (0.69-0.97) 0.019
Endocarditis 2.44 (1.04-5.70) 0.040
Arrhythmia 2.92 (0.86-9.89) 0.085
Emergency surgery 1.98 (0.71-5.56) 0.192
RF 1.12 (0.24-5.29) 0.885
  1. HR: hazard ratio; 95% CI = 95% confidence interval; RF = renal failure.
  2. Significant results (p < 0.005) are highlighted in bold.
