Sleep Disordered Breathing (SDB, eg: snoring & Obstructive Sleep apnea) are associated with abnormal Heart rhythms, impaired glucose tolerance and Insulin resistance. Now according to a recent study of 647 people with ischemic ( reduced blood flow) and non-ischemic heart failure, all who were screened for SDB, showed a 70% prevalence of SDB in people with non-ischemic heart failure and a 82% prevalence among people with ischemic heart failure. Therefore the results suggest that a routine screening for SDB should be part of the investigations for patients with heart failure.
