Cathepsin K-deficiency impairs mouse cardiac function after myocardial infarction.
Extracellular matrix metabolism and cardiac cell death participate centrally in myocardial infarction (MI). This study tested the roles of collagenolytic cathepsin K (CatK) in post-MI left ventricular remodeling.
METHODS AND RESULTS:
Patients with acute MI had higher plasma CatK lev…
Accelerated collagen turnover in women with angina pectoris without obstructive coronary artery disease: An iPOWER substudy
Collagens are major cardiac extracellular matrix components, known to be actively remodelled and accumulated during diffuse myocardial fibrosis. We evaluated whether accelerated collagen turnover described by neo-epitope biomarkers reflecting collagen formation and degradation separates patie…
