Circulating microRNAs as biomarkers of Chagas cardiomyopathy

Frontiers in Cardiovascular Medicine

DECEMBER 18, 2023

Methods We carried out a case-control study to identify circulating miRNAs associated with CHCM. We performed a clinical, echocardiographic, and laboratory evaluation and profiled circulating miRNA in the serum samples. Results Differences between groups were observed in clinical variables and in the analysis of miRNAs.
