Key result
Sleep-disordered breathing affects 80% of patients with DCM, far exceeding rates in HCM.
Why the study?
Sleep-disordered breathing may adversely affect heart function and contribute to heart failure progression in patients with idiopathic cardiomyopathy.
Cross-Sectional (n=35)
No
Absolute Event Rate: 80% vs 47%
Sleep-disordered breathing is highly prevalent in idiopathic cardiomyopathy, with central sleep apnea being common in DCM and obstructive sleep apnea associated with higher BMI in both DCM and HCM.
No takes yet. Share an insight, caveat, or question.
High SDB prevalence in idiopathic cardiomyopathy supports targeted screening studies; leaves open whether treatment modifies progression in DCM or HCM.
Banno et al. (2004) conducted a cross-sectional in Idiopathic Cardiomyopathy (n=35). Dilated cardiomyopathy (DCM) vs. Hypertrophic cardiomyopathy (HCM) was evaluated on Prevalence of sleep-disordered breathing. Sleep-disordered breathing was highly prevalent, affecting 80% of patients with dilated cardiomyopathy and 47% of patients with hypertrophic cardiomyopathy.
