NCT05322395

Brief Summary

The primary objective of this study is to assess the feasibility and impact of implementing the ESC 0-1 hour high sensitive troponin pathway in clinical practice and with specific reference to the 0-3 hour pathway currently in use. The principal outcome measure will be the safety of the 0-1 hour protocol (which is less established and has limited data on safety when implemented in clinical practice)

Outcome Measures

Primary Outcomes (2)

  • percentage safe discharge by 4 hours. safety defined as type 1 MI and CV deah

    We will compare safe discharge by each strategy (ie the ESC 0-1 hour pathway versus 0-3 pathway) and the proportion actually discharged by each pathway at 4 hours. The exact definition of safety will be percentage (of cohort randomised to each pathway) safely discharged by 4 hours of presentation to accident and emergency (Safety will be judged by type 1 myocardial infarction, cardiovascular death by 4 weeks with sensitivity \>98% - the study will be powered on safety to establish whether 0-1-hour performance is equivalent to 0-3-hour sampling by means of a non-inferiority analysis- see statistics). (Type 1 myocardial infarction is due to acute coronary atherothrombotic myocardial injury with either plaque rupture or erosion and, often, associated thrombosis. A separate analysis will also be undertaken with inclusion of type 2 MI as well as type 1 MI as an endpoint

Secondary Outcomes (9)

  • Type 1 myocardial infarction

  • All cause death, type 1 myocardial infarction and urgent or emergency revascularisation. This analysis will be repeated incorporating both type 1 and 2 MI definition. (prespecified secondary analysis)

  • Proportion with rule-out or rule-in MI in the 0-1 hour and 0-3 hour

  • HEART ≤3 and a modified HEART score for rule-out MI at 30 days

Study Arms (2)

ESC 0/1 pathway

EXPERIMENTAL

A two-arm parallel group, two-centre pragmatic randomised controlled trial of 0-1-hour high sensitivity troponin T (hs cTnT) compared to a 0-3-hour pathway as rules for rapid discharge of suspected ACS. (both incorporating single presentation sample limit of detection (LOD) high sensitive troponin as a rule for discharge, or cut-off selected by manufacturer). The power of the study is on safety rather than percent discharge achieved by 4 hours as this is the primary focus for clinicians and health care institutions. (By virtue of the earlier sampling the 0-1 hour troponin sampling is likely to allow greater discharges by 4 hours and the sample size for safety easily accommodates this aspect).

Diagnostic Test: ESC 0/1 hour troponin pathway

ESC 0/3 hour pathway

Eligibility Criteria

Age18 Years+
Sexall(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Chest pain with moderate or high suspicion chest pain (see chest pain evaluation chart at end) or any patient the clinician deems suspicious for myocardial ischaemia thus requesting a troponin sample (between daytime hours 0800hrs to 1800hrs)
  • Presentation \<12 hours since onset of chest pain (or unknown duration)
  • Age \>18 years of age

You may not qualify if:

  • ST elevation myocardial infarction (STEMI) infarct on the presenting electrocardiogram (ECG)
  • Symptoms considered definitely non-cardiac
  • Trauma
  • Pregnancy
  • Comorbid conditions requiring hospital admission
  • Coronary artery bypass graft surgery (CABG) \<1 month
  • coexistent clinical conditions likely to preclude follow-up.
