Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This prospective, multicenter, randomized, controlled, open-label clinical study has a target enrollment of 240 subjects. It will explore whether STEMI patients transferred to a PCI center following thrombolytic therapy and expected to have stent implantation might benefit from an alternative treatment strategy and the use of new technologies designed to improve myocardial protection throughout the medical care process.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Eligible patients with STEMI who meet the Inclusion/Exclusion Criteria will receive thrombolytic therapy, and then be transferred to the PCI center for coronary angiography (CAG). Patients having a target vessel with TIMI grade 3 flow as shown by CAG, and and ≥ 50% angiographic stenosis after thrombus aspiration, will be randomized in a 1:1 ratio to either an immediate stenting group or a deferred stenting group. Patients assigned to the immediate stenting group will undergo appropriate stent implantation based on characteristics of the lesions. Patients assigned to the deferred stenting group will be sent back to the ward after PCI to receive standard anticoagulant and antiplatelet therapies, and the CAG will be repeated 5 to 7 days after initial intervention, followed by treatment with stent implantation.

All subjects will be recorded postoperative microcirculation perfusion and ST-segment drop of electrocardiogram and followed up by telephone or in the clinic at 1, 6, and 12 months after discharge from the hospital to obtain information including their general condition, chief complaints or discomforts, details of taking their oral medications, recent relevant test results, and to evaluate the primary endpoint, secondary endpoints.
