Fig 1: Decade of age and the presence of detectable plasma CD39.*P<0.001 based on Fisher exact test.
Fig 2: Summary of the key study findings.Study findings support an inverse relationship between plasma ectonucleotidases, stress myocardial blood flow (CD39), and myocardial flow reserve (CD73). CAC indicates coronary artery calcium; and PET, positron emission tomography.
Fig 3: Catabolic activity of CD39 and CD73 produces anti‐inflammatory adenosine.CD39 catabolizes ATP and ADP, generating inorganic phosphate and AMP, the latter of which is then catabolized by CD73 to form adenosine. Adenosine is known to have vasorelaxant and antithrombotic properties. PET indicates positron emission tomography; and Pi, inorganic phosphate.
