BACKGROUND: Cardiogenic shock is a very serious postoperative complication in patients undergoing heart valve surgery. Mechanical circulatory support is a recognized method of treating patients with this complication. The aim of the presented study was to assess the usefulness of selected biomarkers in predicting the occurrence of postoperative cardiogenic shock requiring mechanical circulatory support. METHODS: This prospective study was conducted on a group of 712 patients undergoing heart valve surgery. The primary end-point at the intrahospital follow-up was postoperative cardiogenic shock requiring mechanical circulatory support. RESULTS: The postoperative cardiogenic shock requiring mechanical circulatory support occurred in 20 patients. At multivariate analysis high-sensitivity Troponin T measured immediately after surgery (OR 1.006; 95% CI 1.002-1.013; P 0.009) remained independent predictor of the primary end point. CONCLUSIONS: The postoperative hs-TnT can be used to predict a postoperative cardiogenic shock requiring mechanical circulatory support.
