[Abstract] Objective: To investigate the value of delayed percutaneous coronary intervention (PCI) in the treatment of ST-elevation acute myocardial infarction (STEMI). Methods: 282 patients with STEMI were divided into two groups according to the duration of PCI. The observation group (n=202) used PCI within 12 to 24h after onset, and the control group (n=80) used thrombolytic therapy within 6h after onset, and then selected the date to use PCI. To compare the cardiac function and prognosis of two groups. Results: After PCI, the number of patients with TIMI<2 of two groups were significantly reduced, and the number of patients with TIMI2 ~ 3 significantly were significantly increased, and there was no significant difference between the two groups (P>0.05). LVESVI and LVEDVI levels were significantly lower and LEVF levels were significantly higher of two groups after PCI 3 months . There was no significant difference in LVESVI, LVEDVI and LEVF between the two groups (P>0.05). The incidence of malignant arrhythmia and severe heart failure in the observation group were significantly higher than those in the control group (P<0.05).Conclusion : Delayed PCI in STEMI patients can unblock infarct-related arteries as soon as possible, and improve cardiac function and reduce cardiac death.
