Early Administration of Heparin At FMC for PPCI of STEMI Patients
A study testing Heparin Sodium Injection in people with STEMI and Primary PCI, run by Renmin Hospital of Wuhan University at 1 site in China.
Trial summary
Heparin is the first choice of anticoagulation drug for primary PCI of STEMI patients. However, the priority of use of hepairn in first medical contact or in Cathlab has not yet studied. Previous study revealed early use of antithrombotic drugs could improve patient's survival. Read more about this study

About this study
Official title: Effectiveness and Safety of Early Administration of Heparin At First Medical Contact for STEMI Patients Undergoing Primary Percutaneous Coronary Intervention: a Multicenter, Prospective, Randomized, Controlled Study
Heparin is the first choice of anticoagulation drug for primary PCI of STEMI patients. However, the priority of use of hepairn in first medical contact or in Cathlab has not yet studied. Previous study revealed early use of antithrombotic drugs could improve patient's survival. Here we supposed that use of heparin at first medical contact could increase the TIMI flow 3 grade ratio in STEMI patients and improve patient's survival and/or reduce MACE rather than in Cathlab.
Read the detailed description
This study will recruit 944 STEMI patients undergoing primary PCI with the symptom onset within 12 hours in 36 hospitals in Hubei Province, China. The patients will be 1:1 randomly assigned to the intervention group (IG) and control group (CG). Patients in IG will be intravenously administrated with sodium heparin (100U/Kg) at first medical contact, while patients in CG will be administrated with sodium heparin (100U/Kg) through catheter sheath in the CathLab.
Inclusion Criteria:
STEMI patient; Symptom onset in 12 hours; Intended to perform PPCI. Exclusion Criteria:Active bleeding; Life expectancy less than 1 year; History of heparin-induced thrombocytopenia; Mechanical complication of MI (VSR, acute MR); History of CABG; On Coagulation drugs; CPR before randomization; Pregnant or lactating woman;Refused to sign the Informed Consent Form.

Questions about this trial
What is this clinical trial studying?
A study testing Heparin Sodium Injection in people with STEMI and Primary PCI, run by Renmin Hospital of Wuhan University 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 1 inclusion and 1 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: finished, as of the sponsor's last update on 27 Mar 2025. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The TIMI 3 flow of the infarct related artery before PPCI (time frame: Coronary angiography, before PPCI，anticipated within 2 hours after randomization). 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 27 Mar 2025; AzTrials last refreshed its copy on 8 Nov 2026.
