Analysis of Predictors of 30-Day Mortality for Patients Undergoing Surgical Repair of Post-Myocardial Infarction Ventricular Septal Defect

Abstract

Aims: Despite the existence of numerous studies devoted to predictors of 30-day mortality in patients with post-myocardial infarction (MI) ventricular septum defect (VSD), the choice of surgical treatment tactics for post-MI VSD remains an item of discussion. The purpose of the research was to determine the most significant risk factors of 30-day mortality in patients with post-MI VSD in order to optimize the tactics of such patients’ surgical repair.
 Study design: The retrospective analysis of the results of a comprehensive examination and surgical treatment of 88 in-patients with post-MI VSD for the period of 2002-2019 was carried out.
 Results: As follows of the research findings, independent predictors of 30-day mortality in patients with post-MI VSD were determined. The predictors identified were combined into a Scoring system to stratify the risk of surgical failure in patients with post-MI VSD. Modelling the surgery outcomes makes it possible to optimize the tactics of surgical treatment of patients with post-MI VSD.
 Conclusion: we have identified the most significant predictors of 30-day mortality in patients with post-MI VSD. The Score designed for mortality risk assessment is easy in use compared to other existing tools used in clinical practices when planning the surgical intervention in post-MI VSD patients. This Score may allow the stratification of post-MI VSD patients.
