Interaction between low-density lipoprotein-cholesterolaemia, serum uric level and incident hypertension

Previous evidence suggest that high low-density lipoprotein cholesterol (LDL-C) and serum uric acid (SUA) levels are risk factors for endothelial dysfunction and vascular ageing. The aim of our study was to evaluate the short-term interaction between SUA, LDL-C and incident hypertension in a sample of overall healthy individuals.In January 2018, we selected from the general database of the Brisighella Heart Study four groups of age and sex-matched nonhypertensive individuals with different levels of LDL-C and SUA level and examined during the 2008 population survey. Incident hypertension has been defined as the increase of SBP values over 140 mmHg and/or of DBP over 90 mmHg and or the beginning of an antihypertensive treatment.In a model adjusted for age, sex, baseline blood pressure, family history of hypertension, smoking status, BMI and physical activity intensity, hazard rations for hypertension development compared with individuals with baseline normal LDL-C and SUA levels are 1.14 [95% confidence interval (95% CI) 0.87-1.55] for individuals with isolated high LDL-C level, 1.55 (95% CI 0.96-2.48) for individuals with isolated high SUA level and 1.57 (95% CI 1.20-2.15) for individuals with both high SUA and LDL-C levels.In an overall healthy population sample, the contemporary presence of suboptimal LDL-C and SUA values is associated with an increased risk to develop hypertension.
