Enzyme Released By Cardiac Mast Cells During Heart Attack Contributes To Arrhythmia, Weill Cornell Team Reports

... In times of cardiac crisis, mast cells in the heart secrete a powerful enzyme, renin, that indirectly triggers dangerous arrhythmias, according to a team of researchers at the Weill Medical College of Cornell University in New York City. The finding, reported in this month's issue of the Journal of Clinical Investigation, follows up on the team's recent breakthrough discovery that local cardiac mast cells produce renin... click link for more info. ...
