Unadjusted and adjusted 15 year temporal trends of PAC use and in‐hospital mortality in cohorts with and without PAC use in AMI‐CS. Panel (A): Unadjusted temporal trends of PAC use in AMI‐CS (P < 0.001). Panel (B): Adjusted multivariable logistic regression for temporal trends of PAC use with 2000 as referent year; adjusted for age, sex, race, primary payer, socio‐economic status, hospital location/teaching status, hospital bed size, hospital region, comorbidity, acute organ failure, cardiac arrest, coronary angiography, percutaneous coronary intervention, mechanical circulatory support, invasive mechanical ventilation, haemodialysis (P < 0.001); Panel (C): Unadjusted temporal trends of in‐hospital mortality in AMI‐CS stratified by PAC use (P < 0.001); Panel (D): Adjusted multivariable logistic regression for in‐hospital mortality temporal trends with 2000 as referent year; adjusted for age, sex, race, primary payer, socio‐economic status, hospital location/teaching status, hospital bed size, hospital region, comorbidity, acute organ failure, cardiac arrest, coronary angiography, percutaneous coronary intervention, mechanical circulatory support, invasive mechanical ventilation, haemodialysis (P < 0.001). The dotted line demarcates the period before and after the ESCAPE trial. AMI, acute myocardial infarction; CS, cardiogenic shock; PAC, pulmonary artery catheter.
