Abstract Aims This study aimed to assess the utility of contemporary clinical risk scores and explore the ability of two biomarkers [growth differentiation factor‐15 (GDF‐15) and soluble ST2 (sST2)] to improve risk prediction in elderly patients with cardiogenic shock. Methods and results Patients (n = 219) from the multicentre CardShock study were grouped according to age (elderly ≥75 years and younger). Characteristics, management, and outcome between the groups were compared. The ability of the CardShock risk score and the IABP‐SHOCK II score to predict in‐hospital mortality and the additional value of GDF‐15 and sST2 to improve risk prediction in the elderly was evaluated. The elderly constituted 26% of the patients (n = 56), with a higher proportion of women (41% vs. 21%, P

Abstract Aims Urgent revascularization is the mainstay of treatment in acute coronary syndrome (ACS) related cardiogenic shock (CS). The aim was to investigate the association of angiographic results with 90‐day mortality. Procedural complications of percutaneous coronary intervention (PCI) were also examined. Methods and results This CardShock (NCT01374867) substudy included 158 patients with ACS aetiology and data on coronary angiography and complications during PCI procedure. Survival analysis was conducted with Kaplan–Meier curves and Cox regression analysis. Median age was 67 ± 11 years, and 77% were men. During 90‐day follow‐up, 66 (42%) patients died. Patients with one‐vessel disease (n = 49) had lower mortality than patients with two‐vessel (n = 59) or three‐vessel (n = 50) disease (25% vs. 48% vs. 52%, P = 0.011). Successful revascularization [Thrombolysis in Myocardial Infarction (TIMI) Flow 3 post‐PCI) was achieved more often in survivors than non‐survivors (81% vs. 60%, P = 0.019). The median symptom‐to‐balloon time was 340 (196–660) minutes, with no difference between survivors and non‐survivors. In multivariable mortality analysis, multivessel disease (HR 2.59, CI95% 1.29–5.18) and TIMI flow
