Clinical features and prognosis analysis of 36 cases with post-infarction ventricular septal rupture / 心血管康复医学杂志

ABSTRACT

Objective:To explore clinical features ,therapeutic program and prognosis of patients with post-infarction ventricular septal rupture (PI-VSR).Methods:Clinical data of 36 PI-VSR patients ,who were treated in our hospital from Dec 2009 to Dec 2016 ,were retrospectively analyzed .According to in-hospital death condition ,patients were divided into in-hospital survival group (n＝14) and in-hospital death group (n＝22).General data were compared between two groups .Multi-factor Logistic regression analysis was used to analyze influencing factors for in-hospital death in PI-VSR patients .Results:All PI-VSR patients received routine medication ,10 cases received intra-aortic balloon pump (IABP) simultaneously , eight cases received transcatheter intervention to occlude VSR and stent im- plantation ,and two cases received ventricular septal repair surgery .In-hospital mortality of PI-VSR patients was 61.1%(22/36).Compared with in-hospital survival group ,there were significant rise in age [55 (46 ,64) years vs . 67 (52 ,82) years] ,percentages of diabetes mellitus (21.4% vs.59.1%) and renal insufficiency (42.9% vs. 90. 9%) ,and significant reductions in LVEF [41 (20 , 48 )% vs.31 (20 , 38 )%] and percentage of surgery (57.1% vs.9.1%) in in-hospital death group ,P＜0.05 or ＜0.01. Multi-factor Logistic regression analysis indica-ted that LVEF and surgery were independent protective factors for in-hospital death in PI-VSR patients (OR＝0.519 ,0.001 ,P＝0.032 ,0.023).Conclusion: PI-VSR is a rare fatal complication of myocardial infarction ,and therapeutic effect of conservative treatment is poor .Transcatheter interventional occlusion is an alternative transi-tional program that might replace surgery in PI-VSR treatment .
