Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Questionnaire of overall health

Intervention Type OTHER

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.
