THIS SHOULD LEAD TO NEW TREATMENTS FAIRLY QUICKLY: Heart Mystery Solved: Scientists Discover Unexpected Source of Cardiac Inflammation. “Researchers have discovered a surprising trigger for heart damage after a heart attack: surviving heart cells near the damaged area become inflamed due to mechanical stress, not immune cells as previously believed. These heart cells rupture and leak DNA, which sparks a damaging immune response. This breakthrough challenges long-held assumptions and offers fresh strategies for preventing heart failure by calming these stressed heart cells and blocking specific inflammatory signals.”
