Acute effects of CPAP on diastolic function in patients with compensated heart failure (CHF) are unknown. The investigators hypothesized that acutely CPAP improves diastolic function, which is associated with increases exercise tolerance.
Objective: To evaluate the acute effects of CPAP on functional capacity and diastolic indices of patients with CHF. This is a randomized trial including 44 patients with compensated heart failure (functional classes II or III, NYHA). Patients will be allocated in CPAP(CPAP with 10cmH2O) or simulated CPAP (null pressure) after computed randomization, in a 1:1 ratio. All subjects shall complete a 6-minute walk test (6MWT) before and after CPAP (30 minutes; 10 cm H2O pressure). Doppler-echocardiogram will be performed before and at the end of CPAP. Wilcoxon or paired t tests were used to compare results, with significance level at p < 0.05.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Diagnostic

The purpose of this study is to see if treatment of OSA with the CPAP device makes a difference to insulin resistance and heart disease.
This study will evaluate whether treating sleep apnea while in the hospital would help heart failure, and assist recovery from the worsening of the heart function more than the current cl...
The objective of this study is to evaluate whether CPAP delivered by bubble CPAP resulted in a greater proportion of infants being successfully extubated when compared with management with...
Heart failure affects approximately 5-6 million North Americans and is increasing in prevalence. Sleep-related disorders, such as obstructive sleep apnea (OSA) often coexist (11-37% incid...
The prevalence of OSA (Obstructive sleep apnea，OSA) is 2%-4% in general population and 16%-47% in surgical-heart failure patients. Our previous study found that OSA was associated with t...
Barriers in heart failure self-care contribute to heart failure hospitalizations, but geographic differences have not been well-studied. We aimed to compare self-care barriers in heart failure patient...
Long-term data on outcomes of participants hospitalized with heart failure (HF) from low and middle-income countries are limited.
The primary aim of the TRIAGE-HF trial was to correlate cardiac implantable electronic device-generated heart failure risk status (HFRS) with signs, symptoms, and patient behaviours classically associ...
Recognizing the rising prevalence of heart failure in China, patients with heart failure have substantial palliative needs. This review highlights recent evidence on the epidemic of heart failure, ide...
Heart failure is an increasing reason for hospitalization and the leading cause of death in patients with adult congenital heart disease (ACHD). Recently, the European Society of Cardiology and the Am...
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.
Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).
