Uric Acid Levels and Endothelial Functions

August 8, 2016 updated by: Amir Lerman, Mayo Clinic

Clinical Follow-up of Patients With Assessment of Endothelial Dysfunction/Coronary Spasm

Uric acid is a risk factor for coronary artery disease (CED) in postmenopausal women but the association with inflammation and coronary microvascular endothelial dysfunction is not well-defined. The aim of this study was to determine the relationship of serum uric acid, inflammatory markers and CED.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Women With CED
All subjects had blood work with included measurement of C-reactive protein, complete blood count with differential, basic chemistry panel, and uric acid level. All subjects completed a standardized questionnaire to assess baseline characteristics. All subjects underwent comprehensive coronary endothelial function assessment. Subjects completed a questionnaire of overall health several years after the index coronary angiogram and endothelial function study.
Other: Questionnaire of overall health
The standardized questionnaire was used to assess occurrence of major adverse cardiovascular events including stroke, re-hospitalization, myocardial infarction or death. Responses were verified by medical record review conducted by an investigator blinded to the results of the standardized questionnaire.
