Cyanidin-3-rutinoside (C3R) possesses anti-oxidant, anti-inflammatory and anti-glycation properties. Methylglyoxal (MG), a highly reactive dicarbonyl aldehyde by-product of glycolysis, is a precursor of advanced glycation end products and contributes to vascular dysfunction, particularly during hyperglycemia. We investigated the possible inherent vasoactivity of C3R, and its effectiveness against MG-induced vascular abnormalities in isolated blood vessel preparations from male Wistar Kyoto rat. C3R induced vasorelaxation concentration-dependently in aortic rings (92% maximum relaxation; EC50: 2...

The optimal target blood pressure (BP) in the treatment of hypertensive patients remains controversial. Recently, the systolic blood pressure trial (SPRINT) has proposed that a target systolic blood pressure of < 120 mmHg provides prognostic benefit in elderly hypertensive patients at high cardiovascular risk. The results of SPRINT contrast with several other intervention trials which have investigated the effect of intense BP lowering (Secondary Prevention of Small Subcortical Strokes [SPS3], Action to Control Cardiovascular Risk in Diabetes [ACCORD], Heart Outcomes Prevention Evaluation [HOPE]-3)...

The enzyme 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) has an essential role in aldosterone target tissues, conferring aldosterone selectivity for the mineralocorticoid receptor (MR) by converting 11β-hydroxyglucocorticoids to inactive 11-ketosteroids. Congenital deficiency of 11β-HSD2 causes a form of salt-sensitive hypertension known as the syndrome of apparent mineralocorticoid excess. The disease phenotype, which ranges from mild to severe, correlates well with reduction in enzyme activity. Furthermore, polymorphisms in the 11β-HSD2 coding gene (HSD11B2) have been linked to high blood pressure and salt-sensitivity, major cardiovascular risk factors...

OBJECTIVES: A goal SBP 120 mmHg or less reduced mortality in high-risk Systolic Blood Pressure Intervention Trial patients; however, mortality implications of concomitant DBP lowering in coronary artery disease (CAD) are uncertain. We examined the relationship between DBP lowering and all-cause mortality with lower achieved SBPs in a large cohort. METHODS: We categorized 17 131 hypertensive patients from the INternational VErapamil-trandolapril STudy US cohort, aged at least 50 years with CAD, by mean achieved SBP (<120, 120 to <130, 130 to <140, and ≥140 mmHg) and DBP tertiles (low, middle, and high per SBP category) during active follow-up...

Abnormally high glycated hemoglobin (Hb) (HbA1c) is significantly associated with oxidative stress and an increased risk of cardiovascular disease (CVD). Serum total bilirubin (T-B) may have a beneficial role in preventing oxidative changes and be a negative risk factor of CVD. Limited information is available on whether serum T-B is an independent confounding factor of HbA1c. The study subjects were 633 men aged 70 ± 9 (mean ± standard deviation (SD)) years and 878 women aged 70 ± 8 years who were enrolled consecutively from among patients aged ≥40 years through a community-based annual check-up process...

Rationale: Lisdexamfetamine is a prodrug of D-amphetamine used for the treatment of attention-deficit/hyperactivity disorder (ADHD). Lisdexamfetamine is thought to have a prolonged pharmacokinetic profile compared with oral D-amphetamine, possibly associated with lower drug liking and a lower risk of oral misuse. However, differences in the pharmacokinetics and pharmacodynamics of lisdexamfetamine and D-amphetamine have not been directly compared. Methods: Equimolar doses of D-amphetamine (40 mg) and lisdexamfetamine (100 mg), and placebo were administered in 24 healthy subjects in a randomized, double-blind, placebo-controlled, cross-over study...

The association between glomerular hyperfiltration and cardiovascular events is not well known. To investigate whether glomerular hyperfiltration is independently associated with risk of adverse outcome we analyzed 8794 participants, average age 52 years enrolled in 8 prospective studies. Of these, 89% had hypertension. Using the 5th and 95th percentiles of the age- and sex-specific quintiles of CKD-EPI-calculated estimated glomerular filtration rate (eGFR), we identified three participant groups with low, high and normal eGFR...
