NCT04185077

Brief Summary

Bivalirudin is recomended by guidelines during primary PCI procedure for patients with STEMI. However, there is a large number of STEMI patients who missed the primary PCI. So the investigators aim to study the efficiency and safety of bivalirudin as the anticoagulation therapy during late PCI.

Outcome Measures

Primary Outcomes (1)

  • Rate of net adverse clinical events

    a composite of major adverse cardiac or cerebral events (all-cause death, reinfarction, ischemia-driven target vessel revascularization, or stroke) or any bleeding as defined by the Bleeding Academic Research Consortium(BARC) definition (grades 1-5).

    30 days after discharge

Study Arms (2)

Experimental

EXPERIMENTAL

Bivalirudin (Salubris Pharmaceuticals Co) was given as a bolus of 0.75mg/kg followed by infusion of 1.75mg/kg/h during the PCI procedure and for at least 30 minutes but no more than 4 hours afterwards. Following this mandatory infusion, a reduced-dose infusion (0.2mg/kg/h) for up to 20 hours could be administered at physician discretion. An additional bivalirudin bolus of0.3mg/kgwasgivenif the activatedclotting time 5minutes after the initial bolus (measuredwith the Hemotec assay) was less than 225 seconds.

Drug: Bivalirudin

Control

ACTIVE COMPARATOR

a bolus dose of 100 U/kg Heparin was administered according to current guidelines.Additional heparinwasadministered if the post-bolus activated clotting time was less than 225 seconds.

Drug: Heparin

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients aged over 18 years.
  • Patients with ST-segment elevation MI (STEMI) undergoing late PCI 24 hours to 2 weeks after symptom onset. STEMI was defined as ST-segment elevation ≥0.1 mV in ≥2 contiguous leads or documented newly developed left bundle branch block.
  • Patients with develop Q-waves at presentation and with clear culprit vessel confirmed by angiography or other clinical evidences.
  • No any other anticoagulation therapy 12 hours before late PCI.

You may not qualify if:

  • \- STEMI patients undergoing primary PCI in 24 hours after symptom attack; patient unwilling or unable to provide written informed consent. thrombolytic therapy administered before randomization; any condition making PCI unsuitable or that might interfere with study adherence;
