Gender-related association of serum uric acid and left ventricular hypertrophy in hypertension.
BACKGROUND
The aim of the present study was to determine whether sex differences contribute to the association of serum uric acid and left ventricular hypertrophy in individuals with hypertension.


RESULTS
Seventy participants with essential hypertension (34 men, 36 women; 54.4 +/- 1.6 years old) were enrolled to undergo echocardiography to calculate the left ventricular mass index (LVMI). Twenty-four-hour ambulatory blood pressure monitoring was done to assess blood pressure level precisely. The LVMI was significantly correlated with serum uric acid (r = 0.295, p = 0.013) in all participants. After controlling for factors such as age, sex, mean 24-h systolic blood pressure, creatinine clearance, and duration of hypertension, serum uric acid was still found to be significantly and independently associated with LVMI. Because serum uric acid was significantly higher in men than in women (6.8 +/- 0.3 and 5.1 +/- 0.2 mg/dl, respectively), subsequent analysis was performed by gender. Multiple regression analysis revealed that the LVMI was significantly and independently associated with serum uric acid in women, but not in men.


CONCLUSIONS
The potential effect of uric acid on LV hypertrophy is more pronounced in female than in males with essential hypertension.
