About this study

Official title: Safety and Efficacy of Thrombus Aspiration in Patients With ST-segment Elevation Myocardial Infarction (STEMI)

This is a prospective, randomized study with blinded outcome assessment, comparing routine manual thrombus aspiration with no aspiration in patients with acute ST-segment elevation myocardial infarction (STEMI) underwent percutaneous coronary intervention (PCI).

Read the detailed description

This is a prospective, randomized study with blinded outcome assessment, comparing routine manual thrombus aspiration with no aspiration in patients with acute ST-segment elevation myocardial infarction (STEMI) underwent percutaneous coronary intervention (PCI). Patients who are diagnosed as STEMI and referred for PCI will be enrolled. They will be randomized 1:1 to either manual thrombus aspiration with PCI group or PCI alone group.The primary outcome is the composite of cardiovascular death, recurrent myocardial infarction (MI), cardiogenic shock, stroke, new or worsening NYHA class IV heart failure during 1 year follow-up. The secondary efficacy outcome are stent thrombosis, target vessel revascularization, left ventricular function and quality of life during 1 year follow-up.

Being tested
percutaneous coronary intervention (PCI), thrombus aspiration
Medical subject headings
ST Elevation Myocardial Infarction

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing percutaneous coronary intervention (PCI) and thrombus aspiration in people with ST-segment Elevation Myocardial Infarction, run by Xijing Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Dongdong Sun, M.D.,Ph.D. (86 29 84775183, wintersun3@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major adverse cardiac events (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2015.
