Mild Versus Moderate Therapeutic Hypothermia in Out-of-hospital Cardiac Arrest Patients (CAPITALCHILL)
This trial is currently a single-center, randomized, double-blind investigator initiated prospective clinical trial initiated at the University of Ottawa Heart Institute (UOHI). The plan is to expand the trial shortly as a multi-center project. The patients for this study will be recruited amongst comatose survivors of out-of-hospital cardiac arrest (OHCA). The aim of this study is to determine whether neurologic outcomes at six months are improved with moderate (31 degrees Celsius) versus mild (34 degrees Celsius) therapeutic hypothermia (TH) following return of spontaneous circulation (ROSC) in patients suffering OHCA, with ROSC defined as the resumption of sustained perfusing cardiac activity.
The primary outcome will be the proportion of patients experiencing death or a poor neurologic outcome at six months after out of hospital cardiac arrest.

- Number of participants with death or poor neurologic outcome at 6 months [ Time Frame: Six months ]The primary outcome of the study will be death or poor neurologic outcome at six months. Neurologic outcome will be assessed by a specialist in rehabilitation medicine using the Disability Ratings Scale (DRS. Patients will be judged to have had a poor neurologic outcome if the score on the DRS scale is >5.
- Number of mortality [ Time Frame: 30 days and 6 months ]All cause mortality will be recorded. Mortality will be adjudicated as cardiac versus non-cardiac.
- Number of participants with stroke [ Time Frame: 30 days and 6 months ]Stroke will be classified as hemorrhagic versus non-hemorrhagic.
- Number of participants with bleeding [ Time Frame: During index hospitalization ]Bleeding will be assessed using the TIMI definition and will be scored as major or minor.
- Length of stay in the unit [ Time Frame: Admission to unit to discharge from unit ]
- Length of stay in the hospital [ Time Frame: Admission to hospital to discharge from hospital. ]
- Number of participants with cardiogenic shock [ Time Frame: During index hospitalization ]
- Number of participants with repeat circulatory arrest requiring cardiopulmonary resuscitation (CPR) [ Time Frame: Six months ]
- Number of participants with seizures [ Time Frame: During index hospitalization ]
- Number of participants with renal failure requiring renal replacement therapy [ Time Frame: During index hospitalization ]
- Number of participants with ventilator associated pneumonia [ Time Frame: During index hospitalization ]
- Number of participants with stent thrombosis [ Time Frame: Six months ]
- Number of participants discharged home [ Time Frame: Six months ]
