Abnormal nocturnal oximetry common in hypertrophic cardiomyopathy

By Kelley Luckstein

Nocturnal oximetry is often abnormal in patients with hypertrophic cardiomyopathy, researchers report in the November 3rd Journal of the American College of Cardiology.


"Our study's discovery that nighttime oxygen desaturations are common in patients with hypertrophic cardiomyopathy raises the importance of screening for obstructive sleep apnea in this patient population," Dr. Mackram F. Eleid from Mayo Clinic College of Medicine, Scottsdale, Arizona, told Reuters Health in an email.


Dr. Eleid and colleagues used nocturnal oximetry to monitor 100 patients with hypertrophic cardiomyopathy and 100 age- and sex-matched controls.
