What is the prevalence of sleep-disordered breathing in diastolic heart failure?
A study by Chan et al. (1997) found that the prevalence of sleep-disordered breathing in diastolic heart failure was 11.3%. This was higher than the prevalence found in the general population (4.3%) and patients with systolic heart failure (6.3%). The authors suggest that sleep-disordered breathing may play an important role in the pathophysiology of diastolic heart failure and that screening for sleep-disordered breathing should be considered in patients with diastolic heart failure.
