Abstract
- Background There is debate regarding the predictive value of interventricular septum (IVS) wall thickness for adverse events. Aims The study investigated the association between the severity of thickened IVS and all-cause death in Chinese patients with coronary artery disease (CAD). Methods A total of 2297 CAD patients verified by angiography was consecutively included. Patients were grouped according to the severity of thickened IVS. Cox regression analysis was conducted to determine the independent prognostic value of thickened IVS for all-cause death. Results During a median follow up of 25 months, 149 patients died. A gradient increase in the risk of death was observed across thickened IVS groups. Compared to patients with normal IVS thickness, the adjusted hazard ratio (HR) was 1.49 (95% confidence interval (CI) 1.00–2.23, P = 0.05) and 2.13 (95% CI 1.29–3.54, P = 0.003) for all-cause death in those with mildly and moderately/severely thickened IVS respectively. For one unit increase in IVS thickness, the risk of all-cause death was elevated by 14% (adjusted HR 1.14, 95% CI 1.05–1.24, P = 0.003). In patients with normal indexed left ventricular mass, thickened IVS was also demonstrated as an independent risk factor for all-cause death. Conclusion Thickened IVS can be served as a reliable marker for predicting all-cause death in Chinese patients with CAD, even in those with normal left ventricular mass.
