Abstract
BackgroundThe ACTION-SHOCK registry offers a decade-long perspective on patients admitted with cardiogenic shock (CS). AimsTo assess trends in the management and outcomes of patients with CS over 10 years. MethodsTrends in the characteristics, management and outcomes of patients with CS admitted into the cardiac intensive care unit of Pitié-Salpêtrière hospital from 2011 to 2020 were analysed. Short-term outcomes included in-hospital mortality, heart transplantation or ventricular assist device. Long-term outcomes were all-cause death or readmission for acute heart failure at 1 year. ResultsOver a 10-year period, data from 700 patients with CS (median [interquartile range] age 61 [50–72] years; 73% of men) were analysed. The proportion of CS related to acute myocardial infarction decreased (from 45% in 2011–2012 to 27% in 2019–2020) while the proportions related to chronic coronary syndrome (18% to 23%) and non-ischaemic cardiomyopathies (37 to 51%) increased (P<0.01). The use of rescue extracorporeal membrane oxygenation remained stable (19 to 14%) and intra-aortic balloon pump use decreased (22% to 7%) (P<0.01). In-hospital mortality remained stable (27 to 29%) as did the proportions of patients discharged after transplantation (17 to 14%) or with a durable ventricular assist device (2 to 4%). Among patients discharged alive, death or readmission for acute heart failure at 1 year remained high (37 to 47%). ConclusionCS remained associated with a poor prognosis over the last decade. There are significant unmet needs in the management strategies of patients with CS.
