Coronariography in OUt of hosPital Cardiac arrEst


Brief description of study

Prospective, multicenter, randomized clinical trial. Survivors from an out-of-hospital cardiac arrest (OHCA) without ST segment elevation in their EKG will be recruited. Potentially non-cardiac etiology of the cardiac arrest will be ruled out prior to randomization. Primary goal (treatment): to evaluate the efficacy of urgent vs deferred coronary angiography in survivors from OHCA without ST-segment elevation in the EKG.

Detailed Study Description

Prospective, multicenter and randomized clinical trial. Survivors from Out-of-Hospital Cardiac Arrest (OHCA) who do not show ST elevation in their EKG will be recruited in the present study. Potentially non-cardiac ethiology of the cardiac arrest will be ruled out prior to randomization. Afterwards, patients will be randomized to emergent or deferred (performed before discharge) coronary angiography. Both groups will receive routine care in the Acute Cardiac Care Unit, including therapeutic hypothermia.

The randomization will be in a 1:1 ratio to urgent or deferred coronary angiography.

The main objective of the study is to compare the effectiveness of an urgent coronary angiography and angioplasty if necessary versus a deferred coronary angiography in survivors from OHCA who after recovery of spontaneous circulation do not fulfill criteria for ST-elevation myocardial infarction.

The primary efficacy endpoint is a composite of in-hospital survival and six-month survival free of severe dependence, which will be evaluated by using the Cerebral Performance Category (CPC) Scale, being good prognosis represented by the categories 1 and 2.The safety endpoint will be a composite of MACE (Major Adverse Cardiac Events) including: death, reinfarction, bleeding or ventricular arrhythmias.

A total of 166 patients will be included. The estimated duration will be 36 months, with a target follow-up of 6 months. Periods will be divided as follows:

  • Inclusion Period (selection of the population and data collection): 30 months.
  • Monitoring, data analysis, statistical and clinical report: 6 months.

Clinical Study Identifier: NCT02641626
