RELATIONSHIP BETWEEN PLASMA XANTHINE OXIDOREDUCTASE ACTIVITY AND LEFT VENTRICULAR EJECTION FRACTION AND HYPERTROPHY AMONG CARDIAC PATIENTS.

Relationship between plasma xanthine oxidoreductase activity and left ventricular ejection fraction and hypertrophy among cardiac patients.

Background and purposeXanthine oxidoreductase (XOR), which catalyzes purine catabolism, has two interconvertible forms, xanthine dehydrogenase and xanthine oxidase, the latter of which produces superoxide during uric acid (UA) synthesis.An association between plasma XOR activity and cardiovascular and renal outcomes has been previously suggested.We
