INTRODUCTION: Regular exercise is confirmed as a lifestyle treatment option for all obstructive sleep apnea (OSA) patients. It has beneficial effects other than weight loss, although the mechanisms remain unclear. Autonomic function imbalance plays an important role in OSA, so that it is meaningful to observe the effect of exercise on autonomic function. METHODS: Seventy mild to moderate OSA patients were divided into two groups. The exercise group received a 12-week exercise program prescribed according to their first cardiopulmonary exercise tests, while the control group kept previous lifestyle...

BACKGROUND: Ketorolac is used for pediatric analgesia after surgery despite its known platelet inhibition via the arachidonic acid (AA) pathway. The degree of platelet inhibitory effect after cardiac surgery is not well characterized. Thromboelastography with platelet mapping (TEG-PM) is emerging as a frequently used test to evaluate platelet inhibition via the AA pathway. METHODS: Post hoc analysis of a data set collected in a prospective observational cohort study evaluating platelet inhibition in children after congenital heart surgery with cardiopulmonary bypass (CPB)...

Endurance exercise training (ET) stimulates eccentric left ventricular hypertrophy (LVH) with left atrial dilation. To date, the biochemical correlates of exercise-induced cardiac remodelling (EICR) remain incompletely understood. Collegiate male rowers (n = 9) were studied with echocardiography and maximal-effort cardiopulmonary exercise testing (MECPET) before and after 90 days of ET intensification. Mid-regional pro-atrial natriuretic peptide (MR-proANP), N-terminal pro B-type natriuretic peptide (NT-proBNP), and high-sensitivity troponin T (hscTn) were measured at rest, peak MECPET, and 60 minutes post-MECPET at both study time points...

Brain damage is a leading cause of death in patients with cardiac arrest (CA). The accumulation of succinate during ischemia by succinate dehydrogenase (SDH) is an important mechanism of ischemia-reperfusion injury. It was unclear whether inhibiting the oxidation of accumulated succinate could also mitigate brain damage after CA. In this study, rats were subjected to a 6 min of CA, and cardiopulmonary resuscitation (CPR) was performed with administration of normal saline or dimethyl malonate (DMM, a competitive inhibitor of SDH)...

Aortic valve surgery is the definitive treatment for aortic stenosis (AS). No specific recommendation is available on how exercise training should be conducted and evaluated after aortic valve replacement (AVR). This study aimed to examine the effect of aerobic exercise training on exercise capacity following AVR. In addition to our primary outcome variable, peak oxygen uptake (peakVO2 ), the effect on submaximal cardiopulmonary variables including oxygen uptake kinetics (tau), oxygen uptake efficiency slope (OUES) and ventilatory efficiency (VE/VCO2 slope) was evaluated...

BACKGROUND: The mechanism of mitochondrial dysfunction following cardiopulmonary bypass (CPB) in diabetics lacks understanding. We hypothesized that impaired beta-oxidation of fatty acids leads to worsened stress response in this patient population after cardiac surgery. METHODS: After IRB approval, right atrial tissue samples were collected from 35 diabetic and 33 non-diabetics pre- and post-CPB. Patients with HbA1c ≥ 6.0 and a clinical diagnosis of diabetes mellitus were considered to be diabetic...

The 6-minute walk test (6MWT) is a standardised, feasible and reliable measure of sub-maximal exercise capacity that has never been fully validated in systemic sclerosis (SSc). A variety of data suggest that many non-pulmonary aspects of SSc contribute to the test results, thus blunting the ability of the 6MWT to measure changes in lung function. Sources of variability are a training effect, technician experience, subject encouragement, medication, other activities on day of testing, deconditioning and the effects of musculoskeletal conditions and pain...

Owing to significant medical advances, it is now estimated that more than 90% of persons born with congenital heart disease (CHD) will reach adulthood. Medically appropriate physical activity represents an opportunity to improve physical functioning as well as quality of life and psychosocial outcomes. By reviewing published CHD research and clinical recommendations, herein we first summarize how adults with CHD are known to be less physically active and have reduced exercise capacity compared with healthy peers...

BACKGROUND: Prior studies suggested that myocardial deformation is superior to conventional measures for assessing ventricular function. This study aimed to evaluate right ventricular (RV) myocardial deformation in response to increased afterload. Patients with the RV in the systemic position were compared with patients with the RV in the sub-pulmonic position with normal or only slightly elevated systolic right ventricular pressure. Correlations between global longitudinal strain (GLS), radial strain, atrioventricular plane displacement (AVPD), and exercise capacity were evaluated...

Cardiopulmonary bypass (CPB) featuring complete heart isolation and continuous cardiac perfusion is a very promising approach for solving the problem of efficient gene delivery. In the technique presented here, separate pumps are used for the systemic and cardiac circuits. This system permits continuous isolated arrested heart perfusion through optimizing a number of delivery parameters including temperature, flow rate, driving pressure, ionic composition, and exposure time to the cardiac vessels. During complete cardiac isolation, the blood vector concentration trended from 11...

Background Exercise intolerance, obesity, and low hemoglobin (hemoglobin<13 and <12 g/dl, men/women, respectively) are common features of heart failure. Despite serving as potent contributors to metabolic dysfunction, the impact of obesity and low hemoglobin on exercise intolerance is unknown. This study tested the hypotheses, compared with non-obese (NO) heart failure with normal hemoglobin, (a) counterparts with low hemoglobin and obesity or non-obesity will demonstrate reduced peak exercise oxygen uptake; (b) obese with normal hemoglobin will demonstrate decreased peak exercise oxygen uptake; (c) compared across stratifications, obese with low hemoglobin will demonstrate the sharpest decrement in peak exercise oxygen uptake...

BACKGROUND: Exercise training has been shown to be beneficial for persons with multiple sclerosis (MS). Adapted exercise modalities are needed to accommodate those with severe mobility impairment (Expanded Disability Status Scale [EDSS] scores 5.5-6.5). Functional electrical stimulation (FES) cycling is one such exercise modality; however, few studies have examined the feasibility and potential benefits of FES cycling for people with MS with severe mobility impairment. OBJECTIVE: Determine the feasibility of FES cycling exercise for people with MS with severe mobility impairment, and the efficacy of FES cycling exercise for improving mobility and physiological fitness...
