Popis: Cardiogenic shock (CS) is the most severe complication after acute myocardial infarction (AMI) with mortality above 50%. Inflammatory response is involved in the pathology of CS and AMI. In this study, we aimed to evaluate the prognostic value of admission neutrophil-lymphocyte ratio (NLR) in patients with CS complicating AMI.Two hundred and seventeen consecutive patients with CS after AMI were divided into two groups according to the admission NLR cut-off value ≤7.3 and7.3. The primary outcome was 30-day all-cause mortality and the secondary end-point was the composite events of major adverse cardiovascular events (MACE), including all-cause mortality, ventricular tachycardia/ventricular fibrillation, atrioventricular block, gastrointestinal haemorrhage and non-fatal stroke. Cox proportional hazard models were performed to analyse the association of NLR with the outcome. NLR cut-off value was determined by Youden index.Patients with NLR7.3 were older and presented with lower lymphocyte count, higher admission heart rate, B-type natriuretic peptide, leucocyte, neutrophil and creatinine (all P .05). During a period of 30-day follow-up after admission, mortality in patients with NLR7.3 was significantly higher than in patients with NLR ≤ 7.3 (73.7% vs. 26.3%, P .001). The incidence of MACE was also remarkably higher in patients with NLR7.3 (87.9% vs. 53.4%, P .001). After multivariable adjustment, NLR7.3 remained an independent predictor for higher risk of 30-day mortality (HR 2.806; 95%CI 1.784, 4.415, P .001) and MACE (HR 2.545; 95%CI 1.791, 3.617, P .001).Admission NLR could be used as an important tool for short-term prognostic evaluation in patients with CS complicating AMI and higher NLR is an independent predictor for increased 30-day all-cause mortality and MACE.
