The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Inclusion Criteria:

1. age ≥45 years;

2. diagnosis of hip fracture during working hours with a low-energy mechanism requiring surgery;

3. troponin elevation ( at least one troponin measurement above the upper limit of normal occurring from the time of hip fracture to the time of randomization); and

4. informed consent.

Exclusion Criteria:

1. taking a therapeutic dose of an anticoagulant for which no reversing agent is available and the anesthesiologist or surgeon believe surgery within 6 hours of eligibility criteria met would not be safe;

2. patients on a therapeutic vitamin K antagonist with a history of heparin induced thrombocytopenia (HIT);

3. patients with peri-prosthetic fracture, open fracture or bilateral fractures;

4. patients requiring an emergency surgery for another reason (e.g., subdural hematoma);

5. patients with acute myocardial infarction deemed to be clinically unstable, with a mechanical complication (i.e., acute papillary muscle rupture, ventricular septal defect), ST elevation myocardial infarction, or cardiogenic shock;

6. patients refusing consent; or

7. patients previously enrolled in HIP ATTACK-2.

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
