Resistance to angiotensin II (Ang II)-induced hypertension in T-cell-deficient male mice with a targeted mutation in the recombination-activating gene-1 (Rag1) on the C57BL/6J background (B6.Rag1(-)(/-) -M), which was reported by 5 independent laboratories including ours before 2015, has been lost. In mice purchased from Jackson Laboratory in 2015 and 2016, the time course and magnitude increase in mean arterial pressure induced by 2 weeks of Ang II infusion at 490 ng/kg per minute was identical between B6...

PURPOSE: Most patients with primary aldosteronism (PA) show a significant decrease in kidney function after surgery. Glomerular hyperfiltration peculiar to PA can mask mild renal failure before surgery. The aim of this retrospective study was to investigate postoperative renal functional outcomes in PA patients from different viewpoints and to develop novel nomograms that can predict renal functional outcomes in PA patients after surgery. METHODS: 130 Japanese PA patients treated by unilateral laparoscopic adrenalectomy were retrospectively surveyed...

OBJECTIVE: According to the JNC7 report, prehypertension category includes subjects with systolic blood pressure between 120 and 139 mmHg and/or diastolic blood pressure between 80 and 89 mmHg that would be at risk for developing hypertension and its untoward sequelae as myocardial infarction and cerebrovascular disease. Moreover, ambulatory blood pressure monitoring made it possible to detect subjects with masked hypertension, who are at risk of greater target organ damage than those with normal ambulatory or home blood pressure...

Masked uncontrolled hypertension (MUCH) has been proven to be associated with increased cardiovascular risk in the general population. We performed the current analysis to determine its prevalence in dialysis patients and its association with pulse wave velocity (PWV). From 368 participants of another cohort study, we selected 145 subjects with controlled predialysis blood pressure (BP). All subjects underwent ambulatory BP monitoring and PWV measurement. MUCH was defined as controlled predialysis BP with daytime BP⩾135/85 mm Hg (definition-1); total ambulatory BP⩾130/80 mm Hg (definition-2); and either daytime BP⩾135/85 mm Hg or nighttime BP⩾120/70 mm Hg (definition-3)...

: The aim of the current article is to review the current evidence on the role of morning blood pressure (BP) in the management of hypertension. Morning BP surge had been and will continue to be a hot topic of hypertension research. However, more evidence is needed to prove its clinical usefulness in the management of hypertension. Masked morning hypertension, as the other forms of masked hypertension, requires more research. The concept of morning BP monitoring could be clinically relevant in the therapeutic management of hypertension and in the prevention of cardiovascular complications by defining and treating morning hypertension...

Blood pressure (BP) control is considered the most important treatment for preventing chronic kidney disease (CKD) progression and associated cardiovascular complications. However, clinic BP is insufficient to diagnose hypertension (HT) and to monitor overall BP control because it does not correlate well with ambulatory blood pressure monitoring (ABPM). We enrolled 387 hypertensive CKD patients (stages G1-G4, 58.4% male with median age 61 years) from 3 hospitals in Korea. HT of clinic BP and ABPM was classified as ≥ 140/90 and ≥ 130/80 mmHg, respectively...

Hypertension remains a major and growing public health problem associated with the greatest global rate of cardiovascular morbidity and mortality. Although numerous factors contribute to poor control of blood pressure (BP) and to pseudoresistance (eg, unawareness, lifestyle habits, nonadherence to medication, insufficient treatment, drug‑induced hypertension, undiagnosed secondary causes), true resistant hypertension (RH) is reported in 10.1% of patients treated for elevated BP. While the mechanisms underlying RH remain complex and not entirely understood, sympathetic activation involved in the pathophysiology of hypertension, disease progression, and adverse complications is further augmented in patients with drug‑resistant hypertension...

Congenital Diaphragmatic hernia (CDH) is a condition characterized by a defect in the diaphragm leading to protrusion of abdominal contents into the thoracic cavity interfering with normal development of the lungs. The defect may range from a small aperture in the posterior muscle rim to complete absence of diaphragm. The pathophysiology of CDH is a combination of lung hypoplasia and immaturity associated with persistent pulmonary hypertension of newborn (PPHN) and cardiac dysfunction. Prenatal assessment of lung to head ratio (LHR) and position of the liver by ultrasound are used to diagnose and predict outcomes...

PURPOSE OF REVIEW: Hypertension is a leading cause of cardiovascular morbidity and mortality, affecting nearly 80 million individuals in the United States alone. Accurate measurement of blood pressure (BP) is the crucial first step to reduce the associated cardiovascular risk of hypertension. For decades, clinicians have relied on office BP measurements for the diagnosis and subsequent management of hypertension. However, it has been clearly demonstrated that ambulatory BP measurements are a better predictor of cardiovascular risk and can provide clinicians with important additional information to improve BP control and reduce cardiovascular risk...

Background. Excessive exercise such as marathon running increases the risk of cardiovascular events that may be related to myocardial infarction and sudden death. We aimed to investigate that the exercise characteristics can be used as a novel indicator of masked hypertension. Methods. A total of 571 middle-aged recreational male marathoners were assigned to a high blood pressure group (HBPG; n = 214) or a normal blood pressure group (NBPG; n = 357). A graded exercise test was used to examine the hemodynamic response and cardiac events, and the personal exercise characteristics were recorded...

Blood pressure (BP) can differ substantially when measured in the clinic versus outside of the clinic setting. Few population-based studies with ambulatory blood pressure monitoring (ABPM) include African Americans. We calculated the prevalence of clinic hypertension and ABPM phenotypes among 1016 participants in the population-based Jackson Heart Study, an exclusively African-American cohort. Mean daytime systolic BP was higher than mean clinic systolic BP among participants not taking antihypertensive medication (127...

To assess the impact of short time hypnosis for retro-bulbar anesthesia on ventilation in patients undergoing ophthalmic surgery of the anterior eye chamber. In all patients, a combined continuous transcutaneous carbon dioxide tension (PtcCO2) and partial oxygen saturation (SpO2) measurement was applied in addition to routine monitoring. To enable unconscious application of retro-bulbar anesthesia, intravenous thiopental was given in one to multiple bolus doses. Transient breathing support included chin lift, Esmarch maneuver and manual hand-bag ventilation via face mask...

Hypertension remains a major and growing public health problem associated with the greatest proportion of global cardiovascular (CV) morbidity and mortality. Although numerous factors contribute to poor blood pressure (BP) control and pseudo-resistance (i.e. unawareness, life-style habits, non-adherence to medication, insufficient treatment, drug-induced hypertension, undiagnosed secondary causes etc.), it is reported that true resistant hypertension (RH) is found in 10.1 % of patients treated for elevated BP...

BACKGROUND AND OBJECTIVE: Elderly patients can be particularly susceptible to the adverse effects of excessive blood pressure (BP) lowering by antihypertensive treatment. The identification of hypotension is thus especially important. Ambulatory BP monitoring (ABPM) is a more accurate technique than office for classifying BP status. This study examined the prevalence of hypotension and associated demographic and clinical factors among very old treated hypertensive patients undergoing ABPM...

Abnormalities in activity of the endothelin (ET) system have been widely reported in a number of cardiovascular disease states such as hypertension and heart failure. Although the vascular responses to ET are well established, the interaction between ET and other important modulators of blood pressure, such as the sympathetic nervous system, are less understood. Previous reports implicate ET signaling through ET type B (ETB) receptors in increasing neuronal activity. Therefore, we hypothesized that activation of ETB receptors on sympathetic nerves would increase blood pressure through an adrenergic-mediated mechanism...
