BIDMC cardiovascular institute researchers will lead $4 million NIH grant to study micrornas

e in cellular functions. Several years ago, scientists began to recognize that these small, noncoding RNAs were not only found inside cells, but could also be found in blood and other tissue fluids.

Using patient plasma samples from extensively characterized patients who have suffered heart attacks, the scientific team will first identify which specific microRNAs are related to poor heart remodeling. They will then use cell culture and animal models of heart disease to further prioritize which microRNAs play a functional role in disease progression. Finally, the investigators will validate these prioritized microRNAs as prognostic markers for poor health outcomes after heart attacks in a large prospective clinical trial.

"Ultimately, we think that miRNA-based tests could replace current tests to predict which patients might be at risk of complications and, therefore, be good candidates to receive an implanted defibrillator," says Das. "At the same time, we hope to be able to better predict which individuals are at less risk of complications and thereby spare them unnecessary and costly procedures."
