ABSTRACT
Objective:To explore the clinical features,surgical treatment and prognosis in acute myocardial infarction (AMI) patients with ventricular septal rupture (VSR) complicating cardiogenic shock (CS).Methods:A total of 77 AMI-VSR patients received surgical repair in our hospital from 2005-01 to 2015-05 were retrospectively studied.The patients were divided into 2 groups:CS group n=52 and Without CS group,n=25.Clinical features were compared between 2 groups and the outcomes in CS group were analyzed.Results:Both groups showed multiple aneurysm (73.0％ vs 68.0％);CS was more occurred in patients with posterior VSR (48.0％ vs 24.0％),P=0.044.Compared to Without CS group,CS group had the larger diameter of VSR (16.16±6.73) mm vs (11.86±4.62) mm,P=0.003;lower LVEF (45.0±8.8) ％ vs (47.9±12.3) ％,higher pre-operative application rates of IABP (34.6％ vs 0％) and vasoactive drugs (96.2％ vs 28.0％),more patients received emergent surgery (42.3％ vs 8.0％) and less patients received elective surgery (57.7％ vs 92.0％),all P＜0.05.In CS group,there were 3 in-hospital death,49 patients survived with the mean follow-up time at (4.5±3.1) years and 2 patients died during that period.Conclusion:Larger or posterior VSR were more likely to develop CS,the patients survived after surgical treatment may have good mid-term outcomes.
