Short term doxycycline treatment induces sustained improvement in myocardial infarction border zone contractility. [PDF]

open access: yes, 2018
Decreased contractility in the non-ischemic border zone surrounding a MI is in part due to degradation of cardiomyocyte sarcomeric components by intracellular matrix metalloproteinase-2 (MMP-2).
