Association of global and disease-specific health status with outcomes following continuous-flow left ventricular assist device implantation

Table 2 Incremental prognostic value of weighted health status over the HeartMate II Risk Score in predicting mortality and rehospitalization after LVAD implantation

	C-statistic (base clinical score only)	C-statistic (base clinical + health status measure)	C-statistic (base clinical score only)	C-statistic (base clinical + health status measure)
	Outcome: Mortality		Outcome: Rehospitalization
Baseline KCCQ (N = 2225)	0.60	0.61	0.51	0.50
Baseline EQ-5D VAS (N = 2205)	0.60	0.60	0.51	0.52
3-month KCCQ (N = 2060)	0.60	0.66	0.52	0.55
3-month EQ-5D VAS (N = 2005)	0.59	0.60	0.52	0.54

Base clinical score was comprised of the variables included in the HeartMate II Risk Score [20] – age, albumin, creatinine, center volume, INR
