Objectives
The study was conducted to evaluate the outcomes of different onset stage of cardiogenic shock (CS) in the patients with ST-segment elevation myocardial infarction (STEMI).
Methods
Total 675 STEMI patients who had undergone primary percutaneous coronary intervention (pPCI) from November 2010 to December 2017 in Nanjing Drum Tower Hospital were enrolled. According to the onset time of CS, the cohort was divided into three groups: Non-CS group, CS on admission group and Developed CS group. The short-term (30 days), middle-term (12 months) and long-term (80 months) outcomes were analyzed. COX proportional hazard models were established for identification of the predictors.
Results
The all cause death, cardiac death and major adverse cardiac events (MACE) at 30 days were similar among the three groups. The incidence of MACE in the CS on admission group was significantly higher than the other two groups at 12 months. As to the long-term outcomes, the CS on admission group had lower survival rate than the other two groups. The Develop CS group had lower survival rate than Non-CS group numerically with a trend towards statistical significance. The incidence of cardiac death in the Non-CS group was the lowest. The incidence of MACE in the CS on admission group was much higher compared with the other two groups. After multivariate analysis, the independent predictors of all cause death included age, male sex, prior stroke and LVEF. The independent predictors of cardiac death included age, male sex, prior stroke, LVEF, CS on admission and developed CS. The independent predictors of MACE included age, prior stroke, LVEF, multivessel lesions, post-PCI TIMI grade 1 and CS on admission.
Conclusions
The long-term outcomes of CS on admission group were the worst of all. The outcomes of Developed CS group laid between the other two groups. The consequences highlighted the importance of prevention for CS developing in the STEMI patients during hospitalization.
