Fluid Shifts in Heart Failure Might Cause Sleep Apnea Nocturnal Rostral Fluid Shift : A Unifying Concept for the Pathogenesis of Obstructive and Central Sleep Apnea in Men With Heart Failure

  • Published 2010
Methods: 57 men with stable HF, NYHA class I to III, and ejection fraction (EF) ≤45 were studied. Leg fluid volume (LFV) was measured by bioelectric impedance; right calf and neck circumference were measured (with lines drawn to ensure consistency) before and after sleep. Patients with predominant OSA (≥ 50% obstructive events) and apnea-hypopnea index (AHI… CONTINUE READING
