3.5 Predictors of Late Mortality and Death from Heart Failure
Cox proportional hazards regression analysis was performed to determine
the effect of PPM on late outcomes after MVR. Multivariable analysis
showed that PPM was an independent predictor of late mortality (hazard
ratio [HR] = 3.38; 95% confidence interval [CI] = 1.69-6.75,p = .001, Figure 2A). Other predictors of late mortality included
NYHA class 3/4, peripheral artery disease, and preoperative LV EF (Table
5). With regards to death from heart failure, PPM was also identified as
an independent risk factor (HR = 31.03, 95% CI = 4.49-214.40, p< .001, Figure 2B). Other independent predictors of death from
heart failure were male, peripheral artery disease, and preoperative LV
EF (Table 5).
