PURPOSE OF REVIEW: Obstructive sleep apnea (OSA) is a highly prevalent condition that has been associated with cardiovascular morbidity and mortality, impaired glucose metabolism and daytime functional impairment. Compared with nonrapid eye movement sleep, rapid eye movement (REM) sleep is associated with higher sympathetic activity and cardiovascular instability in healthy individuals and more so in patients with OSA. RECENT FINDINGS: Recent studies have indicated that REM OSA is independently associated with prevalent and incident hypertension, nondipping of nocturnal blood pressure, increased insulin resistance and impairment of human spatial navigational memory...

BACKGROUND: Obesity has been found to be a predictor of left ventricular hypertrophy (LVH). However, studies which divide obesity into metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) to study the effect of obesity on LVH have been rare. The present study aims to make clear the effects of various obese phenotypes and metabolic abnormalities on LVH. METHODS: A total of 10,804 participants were involved in this cross-sectional study. "Obesity" and "metabolically healthy" were defined as BMI ≥ 25kg/m(2) and having none of the metabolic factors respectively...

BACKGROUND: Sleep apnea is accompanied by some cardiovascular complications. It has even been hypothesized that sleep apnea, itself, can induce some of these complications. Given such controversies, we assessed the left ventricular mass index (LVMI) and systolic pulmonary artery pressure in patients with sleep apnea. METHODS: Through convenience sampling, 56 patients with the obstructive sleep apnea syndrome (OSAS) were included in the present descriptive cross-sectional study...

OBJECTIVE: Menopause can affect the physiological timing system, which could result in circadian rhythm changes and development of napping habits. Whether longtime napping in postmenopausal women is associated with cardiovascular disease is, however, still debated. The present study aims to investigate this association. METHODS: We conducted a population-based study in 4,616 postmenopausal Chinese women. Information on sleep duration was self-reported. The Framingham General Cardiovascular Risk Score was calculated and used to identify participants at high risk of coronary heart disease (CHD)...

The aim of this study was to evaluate the association between sleep duration and blood pressure using a cross-sectional and longitudinal approach. As part of a population-based cohort, 1403 adolescents were evaluated at 13 and 17 years old. Sleep duration was estimated by the difference between self-reported usual bedtime and wake-up time. Blood pressure was measured using the auscultatory method. Regression coefficients (β) and respective 95% confidence intervals were computed to evaluate the association between sleep duration and blood pressure, using linear regression models adjusted for practice of sports and body mass index at 17 years old...
