Study summary

The HIP ATTACK-2 trial is a multicentre, international, parallel group randomized controlled trial to determine whether accelerated surgery for hip fracture in patients with acute myocardial injury is superior to standard care in reducing death at 90 days after randomization. The trial will also assess secondary outcomes at 90 days after randomization: inability to independently walk 3 metres, time to first mobilization (first standing and first full weight bear), composite and individual assessment of major complications (e.g., mortality, non-fatal myocardial infarction, acute congestive heart failure, and stroke), delirium, length of stay, pain, and quality of life.

No

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

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 occurring from the time of hip fracture to the time of randomization); and
  4. .

Exclusion criteria

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.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Individual participant data

Plan to share: No — The Population Health Research Institute (PHRI) is the sponsor of this trial. The PHRI believes the dissemination of clinical research results is vital and sharing of data is important. PHRI prioritizes access to data analyses to researchers who have worked on the trial for a significant duration, have played substantial roles, and have participated in raising the funds to conduct the trial. PHRI balances the length of the research study, and the intellectual and financial investments that made it possible with the need to allow wider access to the data collected. Data will be disclosed only upon request and approval of the proposed use of the data by a Review Committee.

Started Nov 2021 (actual). Primary completion is estimated for Aug 2027, 69 months after the start.

Of 221 non-industry interventional studies with no phase under Hip Fractures, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 55. This study's planned 69 months is above that.

Counting every sponsor, half of 237 studies reached it within 29 months; a quarter within 10 and three quarters within 57.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 26, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
