OBJECTIVE: Rheumatoid arthritis (RA) is a systemic autoimmune inflammatory disorder which further doubles the risk of developing cardiovascular disease. Some studies suggest that in RA patients, the prevalence of hypertension increases due to prednisolone use, clinical status, genetic factors, and physical inactivity. On the other hand, dipper and non-dipper status in RA patients compared to non-RA subjects has not been investigated to our knowledge. Purpose of the study is to investigate whether non-dipper status is more deteriorated in RA patients...

Alexandra Haw, Harold I Palevsky
Pulmonary hypertension has emerged as a major cause of morbidity and mortality in patients with hemoglobinopathies and chronic hemolytic anemias. These hematological diseases include - but are not limited to - sickle cell disease (SCD), thalassemia, paroxysmal nocturnal hematuria, and hereditary spherocytosis. Although most studies have been based on the use of echocardiography as a screening tool for pulmonary hypertension as opposed to the gold standard of right heart catheterization for definitive diagnosis, the association between chronic hemolytic anemia and pulmonary hypertension is evident...

REVIEW
Jacquie Baker, Kurt Kimpinski
Cardiovascular diseases account for approximately one third of all deaths each year. Of this, hypertension accounts for approximately 9.4 million deaths. Melatonin, the primary circadian hormone, has been substantiated as an effective and safe adjunct anti-hypertensive agent. In support of this, melatonin receptors have been identified within the central and peripheral nervous system, as well as the cardiovascular system, including various vascular tissues. Therefore, it is not surprising that recent research has emerged highlighting a key role of melatonin in autonomic regulation of blood pressure...

Purpose: Episodic nocturnal hypercapnia (eNH) caused by rapid eye movement (REM) sleep-related hypoventilation is often noted in patients with advanced COPD. The purpose of this study was to clarify the clinical significance of eNH and the effectiveness of eNH-targeted noninvasive positive pressure ventilation (NPPV). Patients and methods: We enrolled patients with stable, severe, or very severe COPD with daytime arterial partial oxygen pressure PaO2 ≥55 mmHg and daytime arterial partial carbon dioxide pressure PaCO2 <55 mmHg, who underwent overnight transcutaneous carbon dioxide pressure (PtcCO2 ) monitoring from April 2013 to April 2016...

Central alveolar hypoventilation is rarely encountered. This case report describes a young woman who was recently diagnosed with hypertension and ischemic heart disease. She presented to the emergency room with hypercapnic respiratory failure, for which she was mechanically ventilated. This was preceded by an acute upper respiratory tract infection. She was initially suspected to have Guillain-Barré syndrome, but further investigations ruled out neuromuscular or autoimmune disorders. Sleep-related hypoventilation was suspected after she experienced recurrent apneas at night that resulted in re-intubation...

INTRODUCTION: Non-dipper and extreme dipper blood pressure (BP) profiles are associated with a worse cardiovascular prognosis. The relationship between nocturnal BP profile and hypertensive retinopathy (HR) is not fully established. AIM: To assess the association between the prevalence and severity of HR and nocturnal BP. METHODS: We prospectively studied hypertensive patients who underwent 24-hour ambulatory BP monitoring. The population was divided into two groups according to the presence or absence of lesions and compared according to baseline characteristics, nocturnal BP profile (dippers, non-dippers, inverted dippers/risers and extreme dippers) and mean nocturnal systolic (SBP) and diastolic (DBP) BP values...

PURPOSE: Obstructive sleep apnea syndrome (OSAS) can induce dramatic blood pressure (BP) fluctuations during sleep and it can be associated with hypertension. We investigated the properties and associated influential factors of BP fluctuation in severe OSAS with and without hypertension. METHODS: Two hundred one severe OSAS subjects were divided into hypertensive and normotensive groups. BP was continuously monitored via measurement of pulse transmit time (PTT)...

We investigate the impact of dipper status on cardiac structure with cardiovascular magnetic resonance (CMR). Ambulatory blood pressure monitoring and 1.5T CMR were performed in 99 tertiary hypertension clinic patients. Subgroup analysis by extreme dipper (n = 9), dipper (n = 39), non-dipper (n = 35) and reverse dipper (n = 16) status was performed, matched in age, gender and BMI. Left ventricular (LV) mass was significantly higher for extreme dippers than dippers after correction for covariates (100 ± 6 g/m2 vs 79 ± 3 g/m2 , P = ...

Intrarenal renin-angiotensin system (RAS) activation plays an important role in the development of hypertension and renal damage. However, the association between daytime and night-time intrarenal RAS activation and renal structural damage in normotensive IgA nephropathy patients is unclear. We investigated the relationships between urinary angiotensinogen (U-AGT) excretion, which reflects intrarenal RAS activity, and renal structural damage (i.e., endocapillary and mesangial cell hypercellularity, arteriolar hyalinosis and arteriosclerosis levels, and global glomerulosclerosis and tubulointerstitial fibrosis percentages) in 27 normotensive IgA nephropathy patients (age 39...

BACKGROUND: Endostatin, cleaved from collagen XVIII in the extracellular matrix, is a promising circulating biomarker for cardiovascular damage. It possesses anti-angiogenic and anti-fibrotic functions and has even been suggested to be involved in blood pressure regulation. Less is known if endostatin levels relate to circadian blood pressure patterns. In the present paper we studied the association between circulating levels of endostatin and nocturnal dipping in blood pressure. METHODS: We used the CARDIPP-study, a cohort of middle aged, type 2 diabetics (n = 593, 32% women), with data on both 24-hour and office blood pressure, serum-endostatin, cardiovascular risk factors, and incident major cardiovascular events...

The abnormalities of blood pressure (BP) nocturnal decline have been found to be predictive for carotid plaque and lacunar infarction in patients with hypertension. In this study, BP dipping patterns in postmenopausal females with hypertension were investigated. The nocturnal decline of systolic BP (SBP) was evaluated using 24-hour ambulatory BP monitoring (ABPM). A total of 163 postmenopausal females were eventually included in our study. The prevalence of reverse-dipper BP pattern was 32.3% in females with menopause age in their 40s and 40% in their 50s...

Background: Cognitive fluctuations refer to alterations in cognition, attention, or arousal occurring over minutes to hours, most commonly in patients with dementias associated with advanced Lewy body pathology. Their pathophysiologic underpinning remains undetermined. Case presentation: We documented serial blood pressure (BP) measurements in an 86-year-old man with Parkinson's disease dementia experiencing cognitive fluctuations during an office visit. This patient's associated dysautonomia included labile BP with orthostatic hypotension and nocturnal hypertension...

The impact of a nondipping blood pressure (BP) pattern, defined as (awake systolic BP - sleep systolic BP)/awake systolic BP < 0.1, on cardiovascular events in populations with different degrees of carotid atherosclerosis is uncertain. The authors hypothesized that a nondipping BP pattern would show differential predictive power for cardiovascular events, including total cardiovascular death, sudden death, nonfatal cardiovascular events, and nonfatal stroke, between populations with and without carotid atherosclerosis...
