Long-term continuous positive airway pressure (CPAP) treatment is likely to prevent the development of cardiomyopathy and congestive heart failure in patients with severe obstructive sleep apnea, researchers found.
Six months of CPAP in a group of 32 patients resulted in a drop in left atrial ventricular index from 45 mL/m2 at baseline to 31.75 mL/m2 (P<0.001), according to Saleh Al-Mutairi, MD, and colleagues from the University of Manitoba in Winnepeg.
Moreover, left ventricular end-diastolic dimension decreased from 58.70 mm to 51.21 mm (P<0.001), the researchers reported at the annual meeting of the Associated Professional Sleep Societies.
Accumulating scientific evidence has suggested a strong link between obstructive sleep apnea and cardiac morbidity and mortality, most likely because of left ventricular remodeling.
