OBJECTIVES: It is unclear whether blood pressure (BP) without target organ damage should be decreased in patients in the emergency department (ED). It is also uncertain whether any certain class of medications has an advantage over the other in this setting. This study addressed both these questions. METHODS: In this retrospective cohort study, all patients attending a tertiary care ED with elevated BP were evaluated. All patients with target organ damage as well as those with significant active co-morbidities, such as myocardial ischemia, were excluded...

The fawn-hooded hypertensive (FHH) rat serves as a genetic model of spontaneous hypertension associated with glomerular hyperfiltration and proteinuria. However, the knowledge of the natural course of hypertension and kidney disease in FHH rats remains fragmentary and the underlying pathophysiological mechanisms are unclear. In this study, over the animals' lifetime, we followed the survival rate, blood pressure (telemetry), indices of kidney damage, the activity of renin-angiotensin (RAS) and nitric oxide (NO) systems, and CYP450-epoxygenase products (EETs)...

The vascular endothelial growth factor (VEGF) family is important for establishing normal pregnancy, and related single nucleotide polymorphisms (SNPs) are implicated in abnormal placentation and preeclampsia. We evaluated the association between preeclampsia and several VEGF SNPs among Filipinos, an ethnically distinct group with high prevalence of preeclampsia. The genotypes and allelic variants were determined in a case-control study (191 controls and 165 preeclampsia patients) through SNP analysis of VEGF-A (rs2010963, rs3025039) and VEGF-C (rs7664413) and their corresponding receptors VEGFR1 (rs722503, rs12584067, rs7335588) and VEGFR3 (rs307826) from venous blood DNA...

Human serum paraoxonase 1 (PON1) is carried by high-density lipoprotein in blood circulation and is shown to be effective in preventing oxidized phospholipids carried by low-density lipoprotein particles, thus it acts as an antioxidant. Polymorphism in this gene has been investigated for many metabolic diseases, but it is not thought to be a genetic risk factor for essential hypertension. The aim of this study was to determine whether there was an association between PON1 gene polymorphisms and concentration with essential hypertension...

BACKGROUND: Arteriosclerosis evaluated by arterial stiffness is the basic pathophysiological change during the development of hypertension. Cardio-ankle vascular index (CAVI) is an index of arterial stiffness. Hyperhomocysteinemia (HHcy) is an independent risk factor for vascular diseases. However, there was little research about the relationship between CAVI and homocysteine (Hcy) in hypertension subjects with HHcy. METHODS: A total of 330 subjects (M/F 133/197) from Vascular Medicine of Peking University Shougang Hospital were divided into four groups: control group (group 1, normotensive with normal Hcy, n = 149), hypertension group (group 2, n = 113), HHcy group (group 3, n = 30), and hypertension with HHcy group (group 4, n = 38)...

Experimental models recently suggested an interaction between aldosterone and adipose tissue, but clinical investigation has been limited. We studied the effects of eplerenone compared to hydrochlorothiazide (HCTZ) on blood pressure (BP), glucose, and lipid levels in 50 patients with essential hypertension (EHT) and type 2 diabetes mellitus whose BP failed to reach target levels with 8 mg of candesartan alone. BP improved similarly in both groups over the 12-month study period, but BMI, waist circumference, and LDL-cholesterol were decreased in the eplerenone group, while glycohemoglobin was elevated in the HCTZ group...

The aim of our study is to explore the involvement of PPARα and PPARγ in Ang II-induced endothelial injury. We found that Ang II significantly elevated the oxidative stress in HUVECs, causing apoptosis and cellular impairment in a time-dependent pattern. Activation of either PPARα by docosahexaenoic acid (DHA) or PPARγ by rosiglitazone protected the endothelial cells. Interestingly, a more significant effect was observed when DHA and rosiglitazone were administrated together. Moreover, we found that this protection was mediated through the PI3K/Akt pathway...

Although endogenous estrogen is known to offer cardiac and vascular protection, the involvement of estrogen receptors in mediating the protective effect of estrogen on hypertension-induced cardiovascular and renal injury is not fully explained. We aimed to investigate the effects of estrogen receptor (ER) agonists on oxidative injury, cardiovascular and renal functions of rats with renovascular hypertension (RVH). Female Sprague-Dawley rats were randomly divided as control and RVH groups, and RVH groups had either ovariectomy (OVX) or sham-OVX...

The behavioral defense coping response (DefS) as a measure of coping with emotional stress may increase alcohol intake (gamma glutamyl transferase (γGT)), the risk for coronary artery disease (CAD) and insulin sensitivity (homeostasis model assessment, HOMA). We assessed associations between coping and cardiometabolic risk markers in a bi-ethnic cohort (N = 390) from South Africa. Ambulatory blood pressure (BP) and ECG, fasting blood and coping scores were obtained. Africans, and mostly when utilizing DefS, showed higher 24h BP, a low-grade inflammatory state, central obesity, increased HOMA [4...
