TABLE 4.

Cox proportional hazard analysis of one‐year outcomes stratified by timing of insertion of Impella 2.5 and CP (before vs during/after interventional procedure)

		All‐cause death		MACE
		HR [CI]	p	HR [CI]	p
CS	Before adjustment	0.80 [0.53–1.22]	.31	0.93 [0.65–1.35]	.71
	After adjustment	1.13 [0.65–1.96]	1	1.12 [0.72–1.74]	.54
PCI patients with AMI‐CS	Before adjustment	0.61 [0.37–0.99]	.04	0.76 [0.49–1.17]	.21
	After adjustment	0.45 [0.21–0.99]	.009	0.79 [0.41–1.52]	.38
HR‐PCI	Before adjustment	0.32 [0.14–0.73]	.007	0.49 [0.25–0.98]	.04
	After adjustment	0.35 [0.12–0.96]	.001	0.51 [0.23–0.96]	.01

Note: Data are reported as hazard ratio (HR) [confidence interval (CI)] before and after propensity score weighting (PSW) and multivariable weighted cox model adjustment. This analysis aims to detect differences between the compared groups in terms of all‐causes mortality and freedom from MACE in patients with cardiogenic shock (CS) and high‐risk percutaneous coronary intervention (HR‐PCI). Since not all patients with CS underwent PCI, we present analyses on the total CS population as well as among acute myocardial infarction (AMI)—CS cases treated with PCI.
