Study Objectives: Determine if defining two subtypes of sleep-disordered breathing (SDB) events - with or without hypoxia - results in measures that are more strongly associated with hypertension and sleepiness. Methods: A total of 1,022 subjects with 2,112 nocturnal polysomnograms (PSGs) from the Wisconsin Sleep Cohort were analyzed with our automated algorithm, developed to detect breathing disturbances and desaturations. Breathing events were time-locked to desaturations, resulting in 2 indices - desaturating (H-BDI) and non-desaturating (NH-BDI) events - regardless of arousals...

BACKGROUND: Homocysteine-lowering intervention with folate was recently shown to be able to increase day-night difference of blood pressure (BP) in humans indicating a potential relationship between homocysteine and circadian BP variation. We thus sought to investigate the association between plasma total homocysteine level (tHcy) and circadian BP variation in hypertensive adults. METHODS: We enrolled 244 eligible dipping and 249 nondipping BP status adults from 560 adults who were randomly sampled from 5,233 Chinese hypertensive adults who received ambulatory BP monitoring (ABPM)...

Previous studies have indicated that minimal exposure to light-at-night increases depression risk, even at 5 lux, in nocturnal and diurnal mammals. Although such low level light-at-night may be effective for human circadian physiology, the association between exposure to light-at-night and depressive symptoms remains uncertain. Bedroom light intensity was measured objectively and depressive symptoms were assessed between 2010-2014 in Nara, Japan. Of 863 participants (mean age, 71.5 years) who did not have depressive symptoms at baseline, 73 participants reported development of depressive symptoms during follow-up (median, 24 months)...

GOALS: We assessed the relationship between gastroesophageal reflux disease (GERD) and hypertension and whether antiacid therapy could be used to control blood pressure (BP) on hypertension in patients with GERD. BACKGROUND: Gastroesophageal reflux disease (GERD) may provoke cardiovascular disease. Many factors are involved in the development of essential hypertension, but whether GERD has a role needs further study. STUDY: Patients with essential hypertension (n=86) were studied by 24-hour continuous BP monitoring and esophageal impedance and pH monitoring...

Isolated nocturnal hypertension (INH) is characterized by normal daytime blood pressure (BP) and elevated nighttime BP diagnosed by ambulatory BP monitoring. Masked isolated nocturnal hypertension (MINH) is a subtype of INH in which office BP is normal. We studied the frequency and characteristics of INH and MINH in children and young adults. One hundred and ninety-eight subjects seen by the pediatric nephrology service were studied retrospectively. Isolated nocturnal hypertension (INH) and MINH were diagnosed according to daytime and nighttime ABP and office BP in the case of the latter...

BACKGROUND: Clinic resting heart rate (RHR), is one of the cardiovascular parameters more easily measurable. In the general population RHR has been associated with total and cardiovascular mortality and higher rate of vascular events. OBJECTIVE: The case of essential hypertension is in some ways peculiar: in the past decades has often been attributed to hypertensive subjects higher values of RHR than healthy controls as a result of the effects of the different factors leading to the development of essential hypertension itself, first of all the presence of an increased tone of the sympathetic nervous system Methods: Several excellent articles debated the issue of autonomic dysfunction in essential hypertension; nevertheless of this, after various decades of debate, this issue is to-date unresolved...

BACKGROUND: Obesity, systemic arterial hypertension (SAH) and obstructive sleep apnea (OSA) are closely related. Up to 70% of patients with OSA may be asymptomatic, and there is evidence that these patients have cardiovascular disease, especially nocturnal SAH. OBJECTIVES: The aim of this study was to evaluate 24-hour blood pressure circadian variation in asymptomatic, obese individuals with moderate-to-severe OSA and compare it with that in individuals with mild OSA or without OSA...

Patients with nondipper hypertension are known to carry a high risk of cardiovascular complications. Vitamin D deficiency is associated with hypertension. Because vitamin D deficiency activates the renin-angiotensin-aldosterone system (RAAS), we hypothesized that this vitamin would interact with the RAAS to influence blood pressure (BP) in nondipper hypertensive patients. We performed a cross-sectional analysis of 1,007 outpatients with hypertension (HTN). Dipper and nondipper patterns were detected, and the two groups were matched for clinical, laboratory, 25-hydroxyvitamin D (25OHD) levels, and ambulatory blood pressure recording...

BACKGROUND: Masked hypertension (MHTN) and lack of nocturnal dipping in blood pressure (BP) have been linked to the state of inflammation. AIMS: We aimed to assess the frequency of nocturnal patterns of BP and heart rate (HR) in patients with IBD. METHODS: Sixty-three normotensive patients with confirmed IBD during remission and 63 healthy subjects were enrolled in a case-control study. All subjects were monitored for BP and HR over a period of 24 h under ambulatory setting...

Out-of-clinic blood pressure (BP) measurement, eg, ambulatory BP monitoring, has a strong association with target organ damage and is a powerful predictor of cardiovascular events compared with clinic BP measurement. Ambulatory BP monitoring can detect masked hypertension or various BP parameters in addition to average 24-hour BP level. Short-term BP variability assessed by standard deviation or average real variability, diminished nocturnal BP fall, nocturnal hypertension, and morning BP surge assessed by ambulatory BP monitoring have all been associated with target organ damage and cardiovascular prognosis...

The authors sought to determine the association between the blunted morning blood pressure (BP) surge and nocturnal BP dipping of the "riser" pattern in 501 patients with hypertension enrolled in the ACHIEVE-ONE (Ambulatory Blood Pressure Control and Home Blood Pressure [Morning and Evening] Lowering by the N-Channel Blocker Cilnidipine) trial. The patients' sleep-trough morning BP surge and prewaking surge were calculated and then classified according to their nocturnal systolic BP reduction pattern as extreme dippers, dippers, nondippers, and risers...

BACKGROUND: Blockade of the renin-angiotensin-aldosterone system is a cornerstone in cardiovascular disease prevention and hypertension treatment. The relevance of ambulatory blood pressure monitoring (ABPM) has been widely confirmed for both increasing the accuracy of blood pressure (BP) measurements, particularly in pharmacological trials, and focusing on 24 h BP prognostic parameters. The aim of this study was to assess the effects of canrenone addition on ambulatory BP in uncontrolled hypertensive patients already treated with the highest tolerated dose of angiotensin-converting enzyme (ACE) inhibitors or angiotensin II type 1 receptor (AT1R) antagonists plus hydrochlorothiazide (HCT)...

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is related to arterial hypertension. In the present study, we test the hypothesis that patients with severe OSAS have excessive apnea induced blood pressure (BP). METHODS: We investigated 97 patients with an apnea/hypopnea index (AHI) greater than 30. Systolic BP (SBP) was continuously determined by using the pulse transit time (PTT). Apnea/hypopnea induced nocturnal BP fluctuations (NBPFs) were detected and showed phenomena of continuous increases of the SBP baseline...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired disease characterized by clonal hematopoietic stem cell disorder, with increased mortality and morbidity. Venous thrombosis is the most common cause of mortality in PNH. The relationship between PNH and cerebrovascular disease is unclear; few cases are reported in the literature, most of them related to cerebral venous thrombosis; In PNH the involvement of intracranial and extracranial arterial sites is very rare. We report a case of a 49-year-old woman who has a medical history of diabetes mellitus, hypertension, and PNH and presented multiple lacunar strokes in a routine consultation with a hematologist...
