What this trial studies

This clinical trial aims to evaluate the effectiveness of manual thrombus aspiration using an export catheter in patients with ST-segment Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). It is a single-center, randomized, open-label trial that will compare outcomes between patients receiving manual aspiration followed by PCI and those receiving PCI alone. The study will assess in-hospital and short-term adverse events, the incidence of slow flow or no reflow, and the need for intracoronary drugs. Patients will be monitored for major adverse cardiac events (MACE) and complications during their hospital stay and at one-month follow-up.

Who should consider this trial

Good fit: Ideal candidates include patients presenting with symptoms of myocardial ischemia for at least 30 minutes, with definite ECG changes indicating STEMI and total occlusion of the coronary artery.

Not a fit: Patients with a history of cardiac surgery or intervention, or those with a life expectancy of less than 6 months, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved in-hospital outcomes and reduced complications for patients experiencing STEMI.

How similar studies have performed: Previous observational studies have suggested potential benefits of manual thrombus aspiration, but this specific approach is being tested in a randomized setting for the first time.
