Trends in cardiogenic shock complicating acute myocardial infarction

Aims Few studies describe recent changes in the prevalence, management, and outcomes of cardiogenic shock (CS) patients complicating acute myocardial infarction (AMI) in the era of widespread use of invasive strategies. The aim of the present study was to analyse trends observed in CS complicating AMI over the past 10 years, focusing on the timing of CS occurrence (i.e. primary CS, CS on admission vs. secondary CS, CS developed subsequently during hospitalization). Methods and results Three nationwide French registries conducted and designed to evaluate AMI management and outcomes in ‘real‐life’ practice included consecutive AMI patients (n = 9951) admitted to intensive cardiovascular care units (ICCUs) over a 1‐month period, 5 years apart. The prevalence of CS complicating AMI decreased from 2005 to 2015: 5.9%, mean age 74.1 ± 12.7 in 2005; 4.0%, mean age 73.9 ± 12.7 in 2010, 2.8%, mean age 71.1 ± 15.0 in 2015 (P
