The relationship of serum uric acid to hypertension and ischemic heart disease in Hisayama population, Japan.

The association of serum uric acid (SUA) with hypertension, ischemic ECG change, diabetes mellitus, and drinking and smoking habits was studied by multivariate analysis among 1871 residents aged 40 and over in Hisayama, Japan. Blood pressure level and history of hypertension did not correlate with an increased level of SUA when other factors such as serum creatinine, obesity, beta-lipoprotein and leucineaminopeptidase were taken into account. Antihypertensive medication was a significant factor influencing SUA. The association of SUA with Minnesota code 4.1-3 (S-T depression) was insignificant in men and significant in women when other factors influencing SUA were taken into account. Glycosuria was negatively correlated with SUA, while alcohol ingestion has positive correlation. There was no correlation between the amount of tobacco smoked and the level of SUA.
