Cox Proportional Hazards Regression for 28-day Adverse Event

Variable	HR [95% CI]	P-value
LVCPI (per 0.10 W/m²)	0.36 [0.18, 0.71]	0.003
Ischemic CM	3.3 [1.0, 10.7]	0.046
Age	0.99 [0.96, 1.03]	0.74
Female Sex	1.8 [0.6, 5.8]	0.32

LVCPI and history of ischemic CM predicted survival free of adverse events at 28 days, after adjustment using Cox proportional hazards regression. Age and sex were left in the model given their known effects on cardiac power. HR, Hazard ratio; LVCPI, left ventricular cardiac power index; W, Watts; CM, cardiomyopathy.
