miR-208a
rnamiR-208a is released early from damaged myocardium during acute MI, providing an early detection window for cardiomyocyte injury.
Pathway placement
Cascade stepMyocardial injury (shared endpoint)
Confidencehigh
RationaleCardiac-specific, early-release miRNA; detects acute MI before troponin rise.
