Aetiology of suspected cardiogenic shock in the combined SHOCK trial registry and trial (total n = 1422, only first 232 trial patients are included). “Other” includes shock caused by prior severe valvar disease, dilated cardiomyopathy, excess β blockade/calcium channel blockade, haemorrhage, and procedural complications. Aortic dissection, pulmonary embolism, and dynamic subaortic outflow obstruction should also be considered. LVF, left ventricular function; MR, mitral regurgitation; RVF, right ventricular failure; VSR, ventricular septal rupture.
