Heart Failure is the prevalent complication of acute Myocardial Infarction. We aim to identify a biomarker for Heart Failure post-acute Myocardial Infarction. This observational study includes 1062 and 1043 patients with acute Myocardial Infarction in the discovery and validation cohorts, respectively. The outcomes are in-hospital and long-term Heart Failure events. S100A8/A9 is screened out through proteomic analysis, and elevated circulating S100A8/A9 is independently associated with Heart Failure in discovery and validation cohorts. Furthermore, the predictive value of S100A8/A9 is superior to the traditional biomarkers, and the addition of S100A8/A9 improves the risk estimation using traditional risk factors. We finally report causal effect of S100A8/A9 on Heart Failure in three independent cohorts using Mendelian randomization approach. Here, we show that S100A8/A9 is a predictor and potentially causal medicator for Heart Failure post-acute Myocardial Infarction.
