Highly prevalent sleep disordered breathing (SDB) has been recognized as an independent cardiovascular disease (CVD) risk factor. Although these two entities often coexist, there is a shortage of sufficiently-powered studies testing the interplay between the course of sleep apnea and CVD pharmacotherapy. The mutual relationship between treated/untreated obstructive sleep apnea (OSA) with ongoing cardiovascular pharmacotherapies is an evident gap in clinical expertise. Areas covered: In this article, the authors review the available evidence and outline future research directions concerning the reciprocal relationship between the pharmacological treatment of CVD and SDB...

INTRODUCTION: Sleepiness and cardiovascular disease share common molecular pathways; thus, genetic risk factors for sleepiness may also predict cardiovascular disease risk. This study explored the associations between subjective sleepiness and single-nucleotide polymorphisms (SNPs) in candidate genes within oxidative stress, inflammatory, and neuronal pathways, which may contribute to sleepiness and downstream cardiovascular disease risk: Cytochrome B-245, Alpha Polypeptide (CYBA), Cytochrome B-245, Beta Polypeptide (CYBB), Neutrophil Cytosolic Factor (NCF2), Tumor Necrosis Factor-Alpha (TNFA), and Phosphodiesterase 4D (PDE4D)...

 Obstructive sleep apnea (OSA) and Alzheimer's disease (AD) are highly prevalent conditions with growing impact on our aging society. While the causes of OSA are now better characterized, the mechanisms underlying AD are still largely unknown, challenging the development of effective treatments. Cognitive impairment, especially affecting attention and executive functions, is a recognized clinical consequence of OSA. A deeper contribution of OSA to AD pathogenesis is now gaining support from several lines of research...

Cardiovascular diseases are the first cause of death in women. Their frequency is underestimated because of their atypical feminine clinical presentation. The pathway "heart, arteries and women", initiated at Lille's hospital center in 2013, was designed to improve pluridisciplinar approaches for women. Thus, obstructive sleep apnea (OSA), known as a metabolic risk factor, was studied in several works. In post-menopausal women with cardiovascular risk, frequency of OSA seems underestimated. Clinical presentation of OSA in feminine patients can be misleading, and its screening seems essential, in light of its major cardiovascular impact...

BACKGROUND: Chronic intermittent hypoxia (CIH), an important basis of the pathogenesis of organ damage induced by obstructive sleep apnea syndrome (OSAS), is associated with myocardial injury, such as left ventricular dysfunction, apoptosis, and oxidative stress. Endogenous hydrogen sulfide (H2 S) plays an important role in maintaining cardiovascular functions. Many studies have demonstrated that exogenous H2 S has protective effects against myocardial injury induced by various cardiovascular diseases, and inhibiting the generation of endogenous H2 S has opposite effects...

The so-called "metabolic syndrome" (MS), constitutes a cluster of metabolic and cardiovascular abnormalities, including fasting glucose, blood pressure, triglycerides, high density lipoprotein cholesterol (HDL-C), and waist circumference that arise from insulin resistance. Obstructive sleep apnea (OSA) syndrome is characterized by recurrent episodes of partial or complete obstruction of the upper airway, involving cessation or significant decreased airflow, with intermittent hypoxemia, frequent arousals from sleep and recurrent oxyhemoglobin desaturations that interfere with normal sleep patterns generating difficulty falling asleep, unrefreshing sleep and loud snoring...

Study Objectives: While obstructive sleep apnea (OSA) is associated with overall cardiovascular disease and mortality, the association with atherosclerotic cardiovascular disease is less clear, especially in women. Recently, it has been suggested that OSA during REM sleep, associated with long apneas and deep desaturations, could have severe cardio-metabolic consequences. The aim of this study was to investigate whether OSA during REM sleep is associated with early signs of atherosclerosis in a population-based sample of women...

PURPOSE: During sleep, respiratory events readily modulate the autonomic nervous system (ANS). Whether such modulation is caused by the respiratory event itself or the cortical arousal that follows and whether these influences differ across sleep stages are not clear. Thus, we aimed to study the independent and combined effects of respiratory events and cortical arousals on the ANS across sleep stages. METHODS: We recruited 22 male patients with sleep apnea-hypopnea syndrome (SAHS) and analyzed the differences in the indices of heart rate variability among normal respiration (NR), pathological respiratory events without cortical arousals (PR), cortical arousals without respiratory events (CA), and the coexistence of PR and CA (PR&CA), by sleep stage...

RATIONALE: The association between obstructive sleep apnea (OSA) and cardiovascular disease (CVD) is complex, bi-directional, and may vary across groups. Understanding what cardiovascular risk factors vary in their relationship to OSA across population groups may improve the knowledge of the OSA-related CVD susceptibility. OBJECTIVE: To better understand the heterogeneity of associations, we assessed whether associations of OSA with cardiovascular risk factors vary by age, sex, and race/ethnicity...

Women are less likely than men to be diagnosed with obstructive sleep apnea (OSA). We examined contemporary gender differences in symptoms, health status, and quality of life associated with diagnosed OSA and OSA symptoms in a population-based sample. A 2015 postal/on-line questionnaire of 2889 active participants of The North West Adelaide Health Study (response rate = 54%, male n = 704; female n = 856; age 30⁻100 years) assessed previously diagnosed OSA, OSA symptoms, insomnia, doctor-diagnosed medical conditions, and the SF-36...

STUDY OBJECTIVES: Longitudinal studies support the usage of positive airway pressure (PAP) therapy in treating obstructive sleep apnea (OSA) to improve cardiovascular disease. However, the anticipated benefit is not ubiquitous. In this study, we elucidate whether PAP therapy leads to immediate improvements on endothelial function, a subclinical marker of cardiovascular status, by examining the effect of circulating exosomes, isolated from patients before and after PAP therapy, on naive endothelial cells...

Sleep-disordered breathing (SDB) is a risk factor for cardiovascular disease including acute coronary syndrome and acute myocardial infarction, and treating SDB prevents their development and recurrence and improves a patient's prognosis. Therefore, SDB is considered a therapeutic target for cardiovascular disease. In 2010, the Japanese Circulation Society published guidelines for the diagnosis and treatment of SDB in patients with cardiovascular disease. However, therapeutic intervention for patients with SDB was recently reported not to suppress the development or deterioration of cardiovascular disease in three middle- to large-sized randomized clinical trials: the SERVE-HF trial, which examined the effects of adaptive servo-ventilation (ASV) on patients with chronic heart failure (CHF) and central sleep apnea; the CAT-HF trial, which examined the effects of ASV therapy on patients with CHF after acute deterioration; and the SAVE study, which examined the secondary preventive effect of continuous positive airway pressure (CPAP) on patients with ischemic heart disease who had mild to moderate obstructive sleep apnea...

BACKGROUND: Watch-PAT 200, a novel portable sleep device worn on the wrist, has been validated against polysomnography. Although sleep disordered breathing (SDB) screening is recommended in patients with cardiovascular disease, no study has reported a comparison of results from Watch-PAT 200 and level III portable devices.  Methods: Patients (n=140) admitted with a first ST-segment elevation myocardial infarction (STEMI) participated in a hospital-based sleep study using the Watch-PAT 200 and a level III portable device (Embletta Gold) simultaneously within five days of admission...

Objectives: Obstructive sleep apnea syndrome (OSAS) is associated with increased cardiovascular morbidity and mortality. The aim of this study was to assess whether the 10-year risk for cardiovascular disease in newly diagnosed patients with OSAS is increased. Materials and Methods: Recently diagnosed, with polysomnography, consecutive OSAS patients were included. The Systematic Coronary Risk Evaluation (SCORE) and the Framingham Risk Score (FRS) were used to estimate the 10-year risk for cardiovascular disease...

Chronic obstructive pulmonary disease (COPD) is associated with an increased cardiovascular risk, although the pathophysiological mechanisms responsible for this interdependence are not completely known. For instance, the increased sympathetic activity may be implied. The severity of COPD correlates with various arrhythmic manifestations such as atrial fibrillation, atrial flutter, and either sustained or nonsustained ventricular tachycardia. COPD and obstructive sleep apnea syndrome may increase the overall cardiovascular risk, especially in elderly patients...

Bariatric surgery became consensual after the NIH consensus of 1991 and the appearance of laparoscopic approach. This type of operation has a functional role (improvement of quality of life, locomotion and digestive symptoms as gastro-esophageal reflux disease), a prevention role (increase in life expectancy, reduction of risk of cancer and cardiovascular disease) and a curative role (remission of diabetes mellitus, obstructive sleep apnea syndrome and arterial hypertension). The laparoscopic approach for bariatric surgery led to a major reduction of postoperative morbi-mortality...

Patients with obstructive sleep apnea syndrome (OSAS) showed higher prevalence in cardiovascular diseases due to aberrant hypoxia and oxidative stress. However, not all OSAS patients end up with cardiovascular disorders, and identification of novel biomarker will be invaluable for differentiating patients at risk. Here we tested the serum matrix metalloproteinase-9 (MMP-9) levels in 47 untreated OSAS patients and found that the MMP-9 level was positively correlated with severity of OSAS, which was consistent with hypoxia degree and duration...

OBJECTIVE: Untreated obstructive sleep apnea (OSA) is a risk factor for cardiovascular disease including myocardial infarction (MI), congestive heart failure (CHF), and atrial fibrillation (AF). Continuous positive airway pressure (CPAP) is an effective treatment for OSA; however, compliance with CPAP can be challenging for some patients. The objective of this study was to investigate whether uvulopalatopharyngoplasty (UPPP) reduced the risk of cardiovascular complications for patients with OSA...

PURPOSE: We aimed to develop a novel index, the hypoxia burden index (HBI), that reflects the degree and duration of oxygen desaturation, and to determine whether this index is better than the apnea hypopnea-index (AHI) for evaluating obstructive sleep apnea (OSA) and cardiovascular diseases morbidities. METHODS: We retrospectively analyzed 459 adult subjects who underwent overnight polysomnography (PSG) in this study. The HBI was calculated by dividing the total desaturation area of SpO2 below 90% by the TST measured in seconds...
