MedicalResearch.com: What is the background for this study? What are the main findings?
Dr. Devaux: Being able to predict outcome after cardiac arrest would allow tailoring healthcare and would represent a major step forward towards personalized medicine. However, available predictive tools suffer serious limitations and would benefit from novel biomarkers.
The value of microRNAs (miRNAs) as biomarkers has been investigated in various clinical contexts and initial small-scale studies suggested that miRNAs might be useful indicators of outcome after cardiac arrest.
Our work aimed at testing whether these molecules, and in particular the brain-enriched miR-124-3p, can be used to predict outcome after cardiac arrest.
We found that, indeed, circulating levels of miR-124-3p measured 48h after cardiac arrest are robust predictors of neurological outcome and mortality.
The strengths of the study are the use of a large multicenter international cohort (TTM-trial) and the collaboration between LIH and European partners (members of the TTM-trial and the Cardiolinc network) bringing complementary clinical and basic expertise.
MedicalResearch.com: What should readers take away from your report?
Dr. Devaux: MicroRNAs are found circulating in the bloodstream, thus can be easily and non-invasively obtained from patients.
Using miR-124-3p to predict neurological outcome and survival after cardiac arrest would increase accuracy of prognostication and guide clinical decisions without causing patient discomfort.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Dr. Devaux: Although the predictive value of miR-124-3p has been assessed in a multicenter international trial, further studies are required to validate our findings and define how miR-124-3p can be brought to clinical application.
MedicalResearch.com: Is there anything else you would like to add?
Dr. Devaux: It has to be kept in mind that novel biomarkers shall not be considered in isolation but included in multimodal prediction strategies, as recommended by current guidelines.
