Why the study?
What is the prevalence and what are the clinical correlates of sleep-disordered breathing in patients hospitalized with acute decompensated heart failure and LV systolic dysfunction?
Population
105 consecutive patients with LV ejection fraction < 50% hospitalized with acute decompensated heart failure
Design
Cross-sectional
Key result
Sleep-disordered breathing was present in 67% of patients hospitalized with acute decompensated heart failure and left ventricular systolic dysfunction, and was significantly correlated with high BMI and elevated left ventricular filling pressure.

What is the prevalence and what are the clinical correlates of sleep-disordered breathing in patients hospitalized with acute decompensated heart failure and LV systolic dysfunction?
Sleep-disordered breathing, particularly central sleep apnea, is highly prevalent in patients hospitalized with acute decompensated heart failure and correlates with elevated filling pressures (E/e') and loop diuretic use.
Suda et al. (2018) conducted a cross-sectional in Acute decompensated heart failure with left ventricular systolic dysfunction. Sleep-disordered breathing was evaluated on Prevalence of sleep-disordered breathing. Sleep-disordered breathing was present in 67% of patients hospitalized with acute decompensated heart failure and left ventricular systolic dysfunction, and was significantly correlated with high BMI and elevated left ventricular filling pressure.
