This study mainly observed the changes of different cardiovascular antibody levels in STEMI patients undergoing emergency PCI by measuring autoantibodies; and the changes of autoantibodies in STEMI patients compared with coronary angiography-negative patients. At the same time, combined with different cardiovascular antibody levels and various indicators, the effect of ischemia-reperfusion injury and prognosis after emergency PCI in STEMI patients was evaluated. The correlation between autoantibody changes and imaging indicators in STEMI patients was evaluated by cardiac color Doppler ultrasound and CMR.
This study is a prospective cohort study，we want to observe the changes of different cardiovascular antibody levels in STEMI patients undergoing emergency PCI;and combined with different cardiovascular antibody levels and various indicators, evaluate the impact of ischemia-reperfusion injury and prognosis in STEMI patients after emergency PCI.
