Obesity, OSA, Cardiac evaluation

The objective of this study was to analyze the associations between temporomandibular disorders (TMDs) and metabolic syndrome (MetS) components, consequences, and related conditions. This research analyzed data from the Dental, Oral, Medical Epidemiological (DOME) records-based study which integrated comprehensive socio-demographic, medical, and dental databases from a nationwide sample of dental attendees aged 18-50 years at military dental clinics for 1 year. Statistical and machine learning models were performed with TMDs as the dependent variable...

INTRODUCTION: The indications for postoperative admission after tonsillectomy in children >3 years of age are less well defined than for children <3 years old, and typically include severe obstructive sleep apnea (OSA), obesity, comorbidities, or behavioral factors. Inpatient care after tonsillectomy typically consists of respiratory monitoring and support, as respiratory compromise is the most common complication after pediatric tonsillectomy. We aim to evaluate risk factors associated with postoperative oxygen supplementation and to identify high risk populations within the admitted population who use additional resources or require additional interventions...

BACKGROUND: Obesity is a global issue with a major impact on cardiovascular health. This study explores how obesity influences nocturnal cardiac electrophysiology in suspected obstructive sleep apnea (OSA) patients. METHODS: We randomly selected 12 patients from each of the five World Health Organization body mass index (BMI) classifications groups (ntotal  = 60) while keeping the group's age and sex matched. We evaluated 1965 nocturnal electrocardiography (ECG) samples (10 s) using modified lead II recorded during normal saturation conditions...

Background: Nocturnal hypoxemia has been linked to increased cardiovascular morbidity and mortality. Several common diseases, such as sleep-disordered breathing (SDB), heart failure (HF), obesity, and pulmonary disease, coincide with an elevated nocturnal hypoxemic burden with and without repetitive desaturations. Research question: This study aimed to evaluate the association of relevant common diseases with distinctive metrics of nocturnal hypoxemic burden with and without repetitive desaturations in patients undergoing coronary artery bypass grafting surgery...

Catheter ablation is a well-established rhythm control therapy in atrial fibrillation (AF). Although the prevalence of AF increases dramatically with age, the prognosis and safety profile of index and repeat ablation procedures remain unclear in the older population. The primary endpoint of this study was to assess the arrhythmia recurrence, reablation and complication rates in older patients. Secondary endpoints were the identification of independent predictors of arrhythmia recurrence and reablation, including information on pulmonary vein (PV) reconnection and other atrial foci...

Patients with obstructive sleep apnea (OSA) and pulmonary hypertension (PH) have a reduced functional capacity and potential survival. Continuous positive airway pressure (CPAP) is the primary treatment for OSA, and this improves sleep parameters, functional activity, and possibly pulmonary artery pressures (PAPs). This literature review summarizes the available studies that have measured changes in PAPs in patients with sleep apnea following the institution of CPAP. The PubMed.gov database was searched with a combination of keywords including: "Pulmonary Hypertension," "Obstructive Sleep Apnea," and "Continuous Positive Airway Pressure...

Obesity-hypoventilation syndrome (OHS) is associated with many comorbidities. The aim of this study was to evaluate the association between previous continuous positive airway pressure (CPAP) and the prevalence of comorbidities in OHS associated with obstructive sleep apnea (OSA). We performed a retrospective, single-center study at the University Hospital of Martinique, the referral hospital for the island of Martinique. A total of 97 patients with OHS associated with severe OSA on non-invasive ventilation (NIV) were included; 54 patients (56%) had previous treatment of OSA with a positive airway pressure (PAP) device before shifting to NIV (PAP group) and 43 (44%) had no previous treatment of OSA with a PAP device before initiating NIV PAP (no PAP group)...

Background: Obstructive sleep apnea (OSA) is a condition with a high prevalence, linked to an increased risk of cardiovascular disease as well as increased morbidity and death. CPAP is currently considered the "gold standard" treatment for OSA, but more thorough research and testing are required to assess its efficacy on cardiopulmonary function. Objectives: To evaluate pulmonary function of OSA patients, cardiopulmonary exercise tolerance test (CPET) performance, cardiac magnetic resonance imaging (MRI) parameters, and polysomnographic changes before and after 3 months of CPAP therapy...

BACKGROUND: We evaluated heterogeneity in clinical phenotypes among patients with obstructive sleep apnea syndrome (OSAHS) using photoplethysmography (PPG) in cluster analysis. METHODS: All enrolled patients underwent polysomnography (PSG) monitoring while wearing a PPG device. Pulse wave signals were recorded with a modified pulse oximetry probe in the PPG device. The pulse wave-derived cardiac risk composite parameter (CRI) and eight derived signal parameters were used to assess OSAHS phenotype...

Obstructive sleep apnea (OSA) is a common but largely undiagnosed clinical condition, which is turning into a serious public health issue. Of note is that its prevalence is gradually increasing in parallel with the obesity and type 2 diabetes mellitus (T2DM) epidemics. The aim of this article is to comprehensively review the literature in order to evaluate the cardiovascular (CV) risk among patients with OSA and prediabetes or T2DM. OSA seems to be an independent risk factor for the development as well as the progression of T2DM, whereas it is associated with T2DM-related macrovascular and microvascular complications...

Both obstructive sleep apnea(OSA) and obesity can cause myocardial remodeling and cardiac insufficiency via corresponding pathophysiological pathways. Therefore, it is speculated that the superposition of OSA and obesity may cause more severe impairment of cardiac function. The objective of our study was to evaluate the early changes of left ventricular systolic function in obese patients with OSA with three-dimensional speckle tracking echocardiography(3D-STE). This study was conducted with 33 obese OSA, 46 non-obese OSA, and 20 healthy subjects...

STUDY OBJECTIVES: Obstructive sleep apnea syndrome (OSAS) is associated with alterations in heart rate variability (HRV) in relation to chronic autonomic dysfunction. We tested the ability of the deep breathing technique-a simple way to evaluate HRV-to identify patients with OSAS. METHODS: Consecutive patients referred for suspected OSAS (without obesity, diabetes, and heart diseases) were included. They underwent a measure of HRV at rest and of heart rate oscillations during expiration vs inspiration (DeltaHRDB ) when breathing deeply at the resonant frequency of 6 cycles per minute (deep breathing technique) while sitting awake, followed by a nighttime polysomnography...

Background Obstructive sleep apnea (OSA) is often present in coronary artery disease patients and confers a high risk of complications following percutaneous coronary interventions (PCI). The impact of two commonly associated comorbid conditions, chronic obstructive pulmonary disease (COPD) and obesity hypoventilation syndrome (OHS, Pickwickian syndrome) in OSA patients undergoing PCI has never been studied. Methods The National Inpatient Sample (NIS; 2007-2014) was queried using the International Classification of Diseases, Clinical Modification 9 (ICD-9-CM) codes to compare baseline characteristics, comorbidities, and outcomes in adults undergoing PCI with OSA, COPD-overlap syndrome, and OSA+OHS...

Objective: The current study was to evaluate the association of office blood pressure (OBP) and 24h ambulatory blood pressure (ABP) with left ventricular (LV) structure and function in hypertensive patients. Whether the association was modified by sex was also evaluated. Methods: A total of 694 hypertensive patients without cardiovascular disease were retrospectively included from the inpatient clinic. Regression analysis was performed to evaluate the association of OBP and 24h ABP parameters with LV mass index (LVMi), e' velocity and left ventricular hypertrophy (LVH) with adjustment for covariates including age, obesity, diabetes mellitus, obstructive sleep apnea, estimated glomerular filtration rate and antihypertensive drugs...

BACKGROUND: The impact of comorbid disease states on the development of atrial and ventricular arrhythmias in patients with hypertrophic cardiomyopathy (HCM) remains unresolved. OBJECTIVE: Evaluate the association of comorbidities linked to arrhythmias in other cardiovascular diseases (e.g., obesity, systemic hypertension, diabetes, obstructive sleep apnea, renal disorders, tobacco and alcohol use) to atrial fibrillation (AF) and sudden cardiac death (SCD) events in a large cohort of HCM patients...

Obstructive sleep apnea (OSA) is characterized by recurrent complete and partial upper airway obstructive events, resulting in intermittent hypoxemia, autonomic fluctuation, and sleep fragmentation. Approximately 34% and 17% of middle-aged men and women, respectively, meet the diagnostic criteria for OSA. Sleep disturbances are common and underdiagnosed among middle-aged and older adults, and the prevalence varies by race/ethnicity, sex, and obesity status. OSA prevalence is as high as 40% to 80% in patients with hypertension, heart failure, coronary artery disease, pulmonary hypertension, atrial fibrillation, and stroke...

BACKGROUND: There is paucity of information on obstructive sleep apnoea (OSA) and cardiac diseases among Aboriginal Australian patients. This study evaluates the association of various cardiac disease profiles among Aboriginal patients undergoing a diagnostic polysomnography (PSG). METHOD: In this 5-year retrospective study demographics, clinical characteristics, medical and cardiac -conditions were analysed. RESULTS: There were total of 340 eligible patients included in the study...

BACKGROUND: Overweight and obesity are considered to be a global pandemic. Its associations with hypertension, diabetes and hyperlipidemia are important risk factors for cardiovascular diseases. METHODS: This was a retrospective, observational chart review of obese patients who were seen in our outpatient clinic for cardiovascular clearance prior to an intended bariatric surgery between 2004 and 2020. Data from patient's demographics, risk factors, presence of coronary artery disease (CAD) and other cardiovascular diseases were collected from medical charts...

BACKGROUND: Intermittent hypoxia (IH) is the major feature of obstructive sleep apnea syndrome, well-known to induce cardiometabolic complications. We previously demonstrated that IH induces hyperinsulinemia and associated altered insulin signaling in adipose tissue, liver, and skeletal muscle, but impact of IH on cardiac insulin signaling and functional/structural consequences remains unknown. Therefore, the aims of this study were to investigate in both lean and obese mice the effects of chronic IH on the following: (1) cardiac insulin signaling and (2) cardiac remodeling and function...

INTRODUCTION: The safety of bronchoscopy in obese patients and those with obstructive sleep apnea (OSA) is unclear. Our objective was to evaluate the incidence of complications during bronchoscopy under moderate sedation in obese patients and to assess the impact of OSA, body mass index (BMI), and duration of the procedure. METHODS: We performed a retrospective study in adult patients undergoing bronchoscopy from January 2010 to August 2019. All patients with BMI > 30 kg/m2 were included...
