Fluid removal and sleep apnea changes in heart failure patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study follows adults hospitalized with decompensated heart failure and fluid overload to see how diuresis affects obstructive sleep apnea measured with a WatchPAT device. Sleep apnea is assessed before and after fluid removal, with neck circumference, weight, and fluid balance recorded. The study also uses routine clinical data to explore potential relationships between fluid changes and sleep-disordered breathing. Findings may clarify whether fluid management influences sleep apnea severity in this patient population.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Adults aged 18 years or older
* Hospitalized with decompensated heart failure and clinical evidence of fluid overload
* Diagnosis of heart failure (reduced or preserved ejection fraction)
* Clinically indicated for diuretic therapy
* Able to undergo sleep apnea assessment using the WatchPAT device
* Able to provide informed consent

Exclusion Criteria:

* Known central sleep apnea as the predominant sleep-disordered breathing type
* Current treatment with continuous positive airway pressure (CPAP)
* Acute respiratory failure requiring mechanical ventilation
* Conditions preventing proper use of the WatchPAT device (e.g., severe hand or finger injury)
* Hemodynamic instability precluding participation
* Pregnancy
