4Triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C) ratio (TG/HDL-C) has been suggested as a simple method to identify unfavorable cardiovascular outcomes in the general population. The effect of the TG/HDL-C ratio on essential hypertensive patients is unclear. About 900 consecutive essential hypertensive patients (mean age 52.9AE12.6 years, 54.2% male) who visited our outpatient hypertension clinic were analyzed. Participants were divided into quartiles based on baseline TG/HDL-C ratio and medical records were obtained periodically for the occurrence of fatal events and composite major adverse cardiovascular events (MACEs) including transient ischemic attack, stroke, aortic dissection, acute coronary syndrome, and death. Participants were followed for a median of 40 months (interquartile range, 35-44 months). Overall, a higher quartile of TG/HDL-C ratio at baseline was significantly linked with higher incidence of fatal and nonfatal cardiovascular events. Using multivariate Cox regression analysis, plasma TG/HDL-C ratio was independently associated with increased risk of fatal events (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.13-1.37; P≤.001] and MACEs (HR, 1.13; 95% CI, 1.06-1.21; P≤.001). Increased plasma TG/HDL-C ratio was associated with more fatal events and MACEs in essential hypertensive patients.

Early morning blood pressure surge (MBPS) is a risk factor for cardiovascular events (CVEs), but the relationship with uric acid is not well understood. The authors aimed to determine the association between MBPS and increased uric acid and the effect of elevated MBPS and uric acid combination on CVEs. A total of 921 patients underwent 24-hour ambulatory blood pressure monitoring and were followed for a median of 40 months. During this period, 103 (11.2%) CVEs occurred. There was a significant relationship between increasing quartiles of serum uric acid level and increasing values of MBPS (P<.0001). Patients in the highest quartile stratified by elevated MBPS and serum uric acid level had a 3.55 odds of major CVE compared with patients in the lowest quartile. Serum uric acid is associated with MBPS and development of new CVEs. J Clin Hypertens (Greenwich). 2014;16:530-535. ª2014 Wiley Periodicals, Inc.

Developing contrast-induced nephropathy (CIN) after primary percutaneous coronary intervention (pPCI) has a negative impact on survival and morbidity. We assessed the predictive value of serum uric acid (SUA) for the development of CIN in patients with ST-segment elevation myocardial infarction (STEMI) who underwent pPCI. Contrast-induced nephropathy was defined an increase of ≥25% or ≥0.5 mg/dL in creatinine concentrations within 72 hours after pPCI. Patients were divided into 2 groups according to admission median SUA level. Serum uric acid level was <5.4 mg/dL (group 1; n = 222) and ≥5.4 mg/dL (group 2; n = 228). Compared to group 1, development of CIN (12% vs 20%, P < .001) was significantly greater in group 2. Using a cut point of >5.45 mg/dL, the SUA level predicted development of CIN with a sensitivity of 70% and specificity of 67%. In multiple logistic regression analysis, SUA level, diabetes mellitus, left ventricular ejection fraction <50%, contrast volume, estimated glomerular filtration rate, and C-reactive protein level emerged as independent predictors of CIN. In conclusion, elevated SUA is an independent risk factor for the development of CIN after pPCI in patients with STEMI.

In patients with newly diagnosed and untreated essential HT, increased EFT thickness and hs-CRP level are significantly related to impaired LV diastolic function independent from other factors, including age, waist circumference, and 24-h systolic blood pressure.
