    Abstract:
    BACKGROUND: Ventricular septal rupture (VSR) is a rare but well-known mechanical consequence of an acute myocardial infarction (AMI). Even in the later stages of re-perfusion therapy, the result of VSR remains poor. Our aim is to assess the site and size of VSR in relation to the severity of cardiac failure. METHODS: From January 2016 to December 2022, a total of 71 patients with a diagnosis of post-myocardial infarction VSR were admitted to the First Affiliated Hospital of Zhengzhou University, Zhengzhou, China. Data records were retrospectively included in this registry. In all patients, clinical and echocardiographic data were gathered, and statistical analyses were performed. RESULTS: A total of 71 consecutive patients (mean age: 66.27 ± 8.88 years); 50.7% male, 49.3% female, with (M:F) ratio of almost (1:1). Left ventricular ejection fraction (LVEF) was (48.55 ± 10.44%) on echocardiography, and apical VSR was the most common site (69.0%). Overall, the VSD site was strongly related to the VSD size (p = .016), LVEF (p = .012), AMI site (p = .001), and affected coronary vessel (p = .004). Prodromal angina (p = .041), intra-aortic balloon pump (p = .002), affected coronary vessels (p = .020), pro-BNP (p = .000), and LVEF (p = .017) were predictors of the severity of heart failure. CONCLUSIONS: Diabetes mellitus is a common risk factor for post-myocardial infarction VSR. VSR site and size had no relation to the severity of heart failure. A presentation with prodromal angina predicted severe heart failure and a worse prognosis.
