Abstract:
Objective:To analysis the risk factors of early death and long-term outcomes of myocardial infarction complicated with ventricular septal rupture.Methods:A total of 135 patients with myocardial infarction complicated with ventricular septal rupture in Beijing Anzhen Hospital from January 2008 to December 2020 were retrospectively analyzed.According to the survival or death within 30 days after ventricular septal rupture, the patients were divided into the early survival group(n=71)and the early death group(n=64). The clinical characteristics of the two groups were observed, and the risk factors for early death group were analyzed.The long-term outcomes of the surgery group(n=69)and the non-surgery group(n=66)was analyzed.Results:The early mortality rate of patients with myocardial infarction complicated with ventricular septal rupture was 47.4%(64/135). Univariate analysis showed that age, sex, white blood cell count, platelet count, C-reactive protein level, left ventricular end-diastolic diameter, abnormal liver function, pulmonary infection, no surgery repair and Killip grade ≥3 were associated with early death as compared with the early survival group(all P<0.05). Multivariate regression analysis showed that no surgery repair( OR=16.103, 95% CI: 4.400-58.930, P<0.001)and Killip≥3 grade( OR=9.014, 95% CI: 2.506-32.428, P=0.001)and abnormal liver function( OR=5.171, 95% CI: 1.388-19.264, P=0.014)were independent risk factors for early death in patients with myocardial infarction complicated with ventricular septal rupture.During follow-up of 1.0 to 11.8(median 3.2)years, the 2-year and 10-year cumulative survival rates were significantly higher in the surgery group than in the non-surgery group(76.7% vs.16.7%, P<0.001; 73.1% vs.16.7%, P<0.001). Conclusions:No surgical repair, Killip grade ≥3 and abnormal liver function are independent risk factors for early death in patients with myocardial infarction complicated with ventricular septal rupture.The long-term outcomes of surgical treatment for myocardial infarction complicated with ventricular septal rupture is good.
