About this trial

This study is a prospective, multicenter, randomized controlled clinical trial designed to evaluate the safety and efficacy of the coronary sinus balloon pump (manufactured by Shanghai MicroPort Rotapace Medical Technology Co., Ltd.) as an adjunctive therapy during percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). As a pivotal study, it aims to support the product registration application to the National Medical Products Administration (NMPA).

Eligibility criteria

Qualifiers

Subjects aged ≥18 and ≤80 years, clinically diagnosed with ST-segment elevation myocardial infarction (STEMI).

Left ventricular ejection fraction (LVEF) ≤50% and ≥35% as assessed by echocardiography or left ventriculography prior to PCI.

Symptoms of myocardial infarction (e.g., persistent chest pain, with or without shortness of breath, nausea/vomiting, profuse sweating, dyspnea, syncope) consistent with the timing of myocardial ischemia, with symptom onset within 24 hours.

2 mm (0.2 mV) in men ≥45 years old.

Disqualifiers

Presence of an implant or foreign body within the coronary sinus.

The target lesion involves the left main coronary artery, or there is a ≥50% stenosis in the left main coronary artery.

Known allergy or contraindication to drugs or materials required during PCI and the use of the investigational device (including, but not limited to, sirolimus, dual antiplatelet therapy drugs, polyamide, polyurethane, polytetrafluoroethylene, or stainless steel).

Presence of pericardial effusion (moderate or greater), cardiac tamponade, hemodynamically significant left/right shunt, or severe valvular heart disease.
