BACKGROUND: Catheter-based renal denervation (RDN) is a novel treatment for resistant hypertension (RH). A recent meta-analysis reported that RDN did not significantly reduce blood pressure (BP) based on the pooled effects with mild to severe heterogeneity. The aim of the present study was to identify and reduce clinical sources of heterogeneity and reassess the safety and efficacy of RDN within the identified homogeneous subpopulations. METHODS: This was a meta-analysis of 9 randomized clinical trials (RCTs) among patients with RH up to June 2016...

Left ventricular (LV) properties in hypertension (HTN) could be deteriorated by pressure overload, especially in endocardium, resulting in hypertensive heart failure (HHF). We sought to noninvasively examine LV systolic and diastolic functions at three myocardial layers in HTN and elucidate features of HHF by speckle-tracking echocardiography (STE) with high volume rates. We examined normotensive controls (n = 54), HTN patients without LV hypertrophy (LVH) (n = 50), and HTN patients with LVH (n = 40) and HHF patients (n = 45)...

OBJECTIVE: Resting heart rate (RHR) possibly has a hereditary component and is associated with longevity. We used the classical biometric twin study design to investigate the heritability of RHR in a population of middle-aged and elderly twins and, furthermore, studied the association between RHR and mortality. METHODS: In total, 4282 twins without cardiovascular disease were included from the Danish Twin Registry, hereof 1233 twin pairs and 1816 'single twins' (twins with a non-participating co-twin); mean age 61...

Data regarding the effects of selective serotonin reuptake inhibitors (SSRIs), which are a common type of antidepressants, on cardiovascular autonomic function are inconsistent. The present study was conducted to determine the effects of chronic fluoxetine, an SSRI, on blood pressure, cardiac autonomic nervous activities and baroreflex control of heart rate. Male Sprague-Dawley rats were treated with fluoxetine (10mg/kg·day, p.o.) or saline for 14 weeks. Baroreflex function was determined by the sigmoid logistic method based on the heart rate responses to changes in blood pressure elicited by phenylephrine or sodium nitroprusside infusions...

CONTEXT: Hypertension is a common and costly risk factor for cardiovascular disease, but just over half of all adults with hypertension have their blood pressure controlled nationally. In Minneapolis-St Paul, Minnesota, the rate of hypertension control is approximately 70% despite a rate of hypertension control similar to the national average as recently as the first half of the 1990s. OBJECTIVE: The purposes of this study were to identify factors in Minneapolis-St Paul and state-level policies and programs in Minnesota that may have contributed to the more rapid increase in blood pressure control there than that in the rest of the nation and to identify factors that can potentially be replicated in other jurisdictions...

Cardiovascular disease (CVD) is the leading global cause of death, accounting for 17.3 million deaths per year. Preventive treatment that reduces CVD by even a small percentage can substantially reduce, nationally and globally, the number of people who develop CVD and the costs of caring for them. This American Heart Association presidential advisory on dietary fats and CVD reviews and discusses the scientific evidence, including the most recent studies, on the effects of dietary saturated fat intake and its replacement by other types of fats and carbohydrates on CVD...

Background: We previously demonstrated the effectiveness of renal denervation (RDN) to lower blood pressure (BP) at least partially via the reduction of sympathetic stimulation to the kidney. A number of adipocyte-derived factors are implicated in BP control in obesity. Aim: The aim of this study was to examine whether RDN may have salutary effects on the adipokine profile in patients with resistant hypertension (RH). Methods: Fifty seven patients with RH undergoing RDN program have been included in this study (65% males, age 60...

Nitric oxide is one of the major endothelial-derived vasoactive factors that regulate blood pressure (BP), and the bioactive lipid mediator S1P (sphingosine-1-phosphate) is a potent activator of endothelial nitric oxide synthase through G protein-coupled receptors. Endothelial-derived S1P and the autocrine/paracrine activation of S1PR (S1P receptors) play an important role in preserving vascular functions and BP homeostasis. Furthermore, FTY720 (fingolimod), binding to 4 out of 5 S1PRs recently approved by the Food and Drug Administration to treat autoimmune conditions, induces a modest and transient decrease in heart rate in both animals and humans, suggesting that drugs targeting sphingolipid signaling affect cardiovascular functions in vivo...

In clinical practice, circadian rhythms play a prominent role in pharmacokinetics and cell responses to therapy, hence necessitating in designing a defined protocol for drug administration. Clinical evidence for chronopharmacological behavior of cardiovascular active drugs in human subjects has been limited for amlodipine. Hence, the present study was undertaken to study the chronopharmacokinetic and chronopharmacodynamic phenomena of amlodipine and evaluate the effect of time of dosage in hypertensive subjects...

Extracellular fluid volume overload and its inevitable consequence, hypertension, increases cardiovascular mortality in the long term by leading to left ventricular hypertrophy, heart failure, and ischemic heart disease in dialysis patients. Unlike antihypertensive medications, a strict volume control strategy provides optimal blood pressure control without need for antihypertensive drugs. However, utilization of this strategy has remained limited because of several factors, including the absence of a gold standard method to assess volume status, difficulties in reducing extracellular fluid volume, and safety concerns associated with reduction of extracellular volume...
