Background Hypertension is a major risk factor for cardiovascular mortality, as it acts through its effects on target organs, such as the heart and kidneys. Hyperuricemia increases cardiovascular risk in patients with hypertension. Objective To assess the relationship between serum uric acid and target organ damage (left ventricular hypertrophy and microalbuminuria) in untreated patients with essential hypertension. Patients and methods: A cross-sectional study was carried out in 130 (85 females, 45 males) newly diagnosed, untreated patients with essential hypertension. Sixty-five healthy age- and sex-matched non-hypertensive individuals served as controls for comparison. Left ventricular hypertrophy was evaluated by cardiac ultrasound scan, and microalbuminuria was assessed in an early morning midstream urine sample by immunoturbidimetry. Blood samples were collected for assessing uric acid levels. Results Mean serum uric acid was significantly higher among the patients with hypertension (379.7±109.2 μmol/L) than in the controls (296.9±89.8 μmol/L; P<0.001), and the prevalence of hyperuricemia was 46.9% among the hypertensive patients and 16.9% among the controls (P<0.001). Among the hypertensive patients, microalbuminuria was present in 54.1% of those with hyperuricemia and in 24.6% of those with normal uric acid levels (P=0.001). Similarly, left ventricular hypertrophy was more common in the hypertensive patients with hyperuricemia (70.5% versus 42.0%, respectively; P=0.001). There was a significant linear relationship between mean uric acid levels and the number of target organ damage (none versus one versus two: P=0.012). Conclusion These results indicate that serum uric acid is associated with target organ damage in patients with hypertension, even at the time of diagnosis; thus, it is a reliable marker of cardiovascular damage in our patient population.

Abstract Funding Acknowledgements TSGH 108-11 Background Elevated serum uric acid (SUA) is associated with cardiac fibrosis and hypertrophy. A growing body of evidence showed the positive correlation between hyperuricemia (HUA) and left ventricular hypertrophy (LVH), but most studies defined LVH by a single method such as electrocardiogram or echocardiogram; the former is generally used in massive screen but the latter take advantage of the accuracy of LVH. Purpose We conducted this study to concomitantly investigate the association between SUA and electrocardiographic and echocardiographic LVH. Methods We initially enrolled 17,913 healthy individuals, who routinely underwent an annual health exam at our hospital between 2016/1/1∼2016/12/31. Of them, 347 individuals received transthoracic echocardiography because of abnormal results in their electrocardiogram. Amplitudes of 12-lead electrocardiogram were artificially measured by a study assistant under the supervision and by artificial intelligence. HUA is defined as an SUA level of ≥7 mg/dl in men and ≥6 mg/dl in women. Electrocardiographic LVH is defined by the criteria of Cornel voltage and product and Sokolow-Lyon and the Minnesota Code ECG classification. Echocardiographic LVH is defined by LV mass index ≥115g/m² in men or ≥95g/m² in women. Results The HUA group (n = 233) vs. normouricemic group (n = 114) was older and predominant male with greater values of body mass index, systolic and diastolic blood pressure and laboratory biomarkers, including non-high density total cholesterol, fasting glucose impairment, creatinine clearance, and haemoglobin. The two groups had comparable lifestyle choices, including tobacco use, alcohol intake, and physical activities per week. The HUA group compared with the normouricemic group had greater values of S amplitude of V1 plus R amplitude of V5 (3031 ± 2055 uV vs. 2566 ± 1021 uV, P = 0.005), R amplitude in lead I plus S amplitude in lead III (842 ± 443 uV vs. 696 ± 386 uV, P = 0.002) and LV mass index (95 ± 23 g/m² vs. 85 ± 30 g/m², P = 0.001). The prevalence of electrocardiographic and echocardiographic LVH was greater in the HUA group than the normouricemic group (7.0% vs. 2.1%, P = 0.034 for electrocardiographic LVH and 15.8% vs. 7.7%, P = 0.025 for echocardiographic LVH). In multivariate logistic regression analyses, elevated SUA was associated with LVH after the confounders were fully adjusted (OR: 1.38, 95% CI: 1.07-1.77, P = 0.012 for electrocardiographic LVH and OR: 1.58, 95% CI 1.15-2.17, P = 0.004 for echocardiographic LVH). Conclusion Elevated SUA is independently associated with the prevalence of both electrocardiographic and echocardiographic LVH in healthy individuals from Taiwan. Future studies might evaluate urate-lowering effects on the regression of LVH.

Abstract Background and Aims The association between serum uric acid (UA) and left ventricular hypertrophy (LVH) is controversial in chronic kidney disease, whereas in hemodialysis (HD) patients has not been studied until now. Thus, we evaluated the relationship of baseline and time-averaged UA with echocardiographic LVH over a 5-year period in HD patients. Method This longitudinal study was conducted on 225 prevalent HD patients over a 5-year period. Patients were stratified into 3 groups according to their baseline and time-averaged UA levels: lower group (UA&lt;400µmmol/l), intermediate/reference group (UA between 400-450µmol/l) and higher group (UA&gt;450µmol/l). Echocardiography was performed on a non-dialysis day and the presence of LVH was defined based on the left ventricular mass index (LVMI) &gt;131 and &gt;100 g/m2, for men and women, respectively. The patients were followed during a 60 month period. Results During the 5-year follow-up, 81 patients died (36%), and the main causes of death were cardiovascular (CV) related (70%). Survival analysis show that patients with time-averaged UA&lt;400 µmmol/l had a significantly higher all cause (log rank, p=0.003) and CV mortality (log rank, p=0.004) rate, compared to those with time-averaged UA between 400-450 µmmol/l and time-averaged UA&gt;450µmol/l, but this difference was not statistically significant in terms of baseline UA level. A negative correlation was observed between LVH and time-averaged UA (r=-0.26, p=0.001), but not with LVH and baseline UA. Patients in lower time-averaged UA group had significantly higher LVMI compared to patients in intermediate and higher group (153.10± 59.89, 131.62±40.99, 131.19±44.49 g/m2, p=0.029), but from the lowest to the highest baseline UA levels, LVH was not significantly different (146.99±59.20, 141.38±37.52, 126.85±42.48 g/m2, p=0.07). Unadjusted odd ratio of LVH risk in the lower time-averaged UA compared to the reference time-averaged UA group was 3.11 (95% CI=1.38-7.05; p=0.006); and after adjustment for age, gender, diabetes and CV disease, ORs for LVH persisted significant only in the lower time-averaged UA group (OR = 2.82, 95% CI = 1.16–6.88, P = 0.002). On the contrary, baseline UA did not affect unadjusted and adjusted LVH. Conclusion In HD patients the prolonged exposure to hypouricemia is associated with LVH. This paradoxical association can only be explained by the hypothesis that uremic milieu in HD patients changes the influence of uric acid. However, these results should be the subject of further research.

Background.Although the relation between serum uric acid (SUA) and left ventricular hypertrophy (LVH) has been studied for decades, however, their association remains debatable.Methods.This is a retrospective study in which a total of 435 hospitalized Chinese patients with type 2 DKD were enrolled. The subjects were stratified into quartiles according to SUA level. LVH was assessed by two-dimensional guided M-mode echocardiography.Results.There was a significant increase in the prevalence of LVH in patients with type 2 DKD across SUA quartiles (28.9, 26.5, 36.1, and 49.5%;p<0.001). The Spearman analysis indicated that SUA was positively correlated to LVMI and negatively correlated to eGFR. The logistic regression analysis revealed that the odd ratio for LVH in the highest SUA quartile was 2.439 (95% CI 1.265–4.699;p=0.008; model 1) or 2.576 (95% CI 1.150–5.768;p=0.021; model 2) compared with that in the lowest SUA quartile. However, there was no significant increased risk of LVH in the subjects with the highest SUA quartile after adjusting the eGFR (OR = 1.750; 95% CI 0.685–4.470;p=0.242; model 3).Conclusions.In selected population, such as type 2 DKD, the elevated SUA level is positively linked with the increased risk of LVH, but this relationship is not independent of eGFR.
