Objective To investigate the optimal time window for elective PCI in STEMI patients.Meth-ods A total of 113 patients diagnosed with STEMI and treated for longer than 3 days in Bayannur City Hospital from December 2018 to December 2021 were retrospectively analyzed.Patients were divided into two groups ac-cording to the time of onset to PCI treatment:There were 65 cases in the early group(PCI treatment within 3-14 days of onset)and 48 cases in the late group(PCI treatment within 15-28 days of onset).Collect and record,interventional treatment,two groups of patients with general data after admission echocardiographic da-ta,including the final Left Ventricular diastolic Diameter(Left Ventricular End-diastolic Diameter,LVEDD,Left ventricular end systolic diameter,LVESD),Left Ventricular Ejection Fraction(Left Ventricular Ejection Fraction,LVEF),(Left Ventricular Fractional Shortening,LVFS),etc.and Major Adverse Cardiovascular Events(Major Adverse Cardiovascular Events,LVFS)during hospitalization.MACE.mainly including angina,heart failure,arrhythmia,all-cause death,etc.The echocardiogram data of 1 month and 12 months after surgery and the occurrence of MACE within 12 months were collected and recorded in the 2 groups through out-patient follow-up and telephone follow-up.To analyze the effect of elective PCI on the prognosis of patients with different time Windows.Results Comparative analysis of data between the two groups showed that com-pared with the late group,the early group had shorter hospital stay,less number of target vessel occlusion and single vessel lesions,significantly improved cardiac function 12 months after surgery,and fewer MACE events within 12 months,with statistical significance(P＜0.05).Conclusion STMEI patients who miss the optimal reperfusion time window have a good prognosis after PCI within 3-14 days,which can effectively improve left ventricular remodeling,reduce the occurrence of MACE events,improve the quality of life,reduce the length of hospital stay,and avoid uncontrollable factors such as hospital infection.
