Insulin resistance and reduced cardiac autonomic function in older adults: the Atherosclerosis Risk in Communities study

Background Prior studies have shown insulin resistance is associated with reduced cardiac autonomic function measured at rest, but few studies have determined whether insulin resistance is associated with reduced cardiac autonomic function measured during daily activities. Methods We examined older adults without diabetes with 48-h ambulatory electrocardiography ( n = 759) in an ancillary study of the Atherosclerosis Risk in Communities Study....
