Relationship between the Level of Serum Uric Acid and Severity of Coronary Artery Atherosclerosis Determined by Coronary Angiography in Patients with Chronic Stable Angina

Background and purpose: Coronary artery disease (CAD) is the first cause of death in modern societies. It is also the first cause for individual health care cost. Multiple risk factors are mentioned for its development among which elevated uric acid is recently introduced as an inflammatory factor. This study was performed for evaluating the serum uric acid level and severity of CAD determined by coronary angiography in patients with chronic stable angina after considering and adjusting other risk factors such as age, smoking (C.S), hypertension (HTN), hyperlipidemia (HLP) and diabetes mellitus (DM). Materials and methods: This cross-sectional analytic study was performed in 200 patients with chronic stable angina to determine the relationship between the level of serum uric acid and severity of coronary atherosclerosis in angiography. Other common cardiovascular risk factors including age, DM, HTN, HLP and C.S were also considered. Results: A total of 78 women (39%) and 123 men (61%) were included in the study. There were no significant differences between sex and risk factors including DM, HTN, HLP, C.S, age and serum uric acid level. In the studied population, the mean severity of coronary atherosclerosis score measured by Gensini score was 15.8 ± 10.7 and the mean level of uric acid was 10.5±6mg/dl. Significant correlatio
