Cox Proportional Hazards Model Parameter Estimates for Change in Total Cholesterol From Baseline to 3 Months Post-LVAD Implantation as a Continuous Variable

Variable	Hazard Ratio	95% Confidence Interval	P Value
Change in cholesterol, per 1 mg/dL change	0.978	0.967–0.990	<0.001
Age at implant, per 1 y	0.975	0.944–1.008	0.14
Ischemic HF cause	0.694	0.294–1.637	0.40
Bridge to transplantation strategy	0.619	0.272–1.410	0.25
Left ventricular ejection fraction at baseline, per 1%	1.054	0.983–1.130	0.14
Baseline cholesterol, per 1 mg/dL	0.979	0.967–0.991	<0.001

Wald χ²=16.7, 6 degrees of freedom, P for model fit=0.0106, n=129 (34 events). HF indicates heart failure; and LVAD, left ventricular assist device.
