2. Untreated Sleep Apnea
Scientists are uncovering more and more evidence that sleep apnea, a disorder in which breathing periodically stops during sleep, is strongly linked to cardiovascular disease. It’s not easy to sort out cause and effect, especially when people with sleep apnea are more likely to have other risk factors for heart disease like obesity and diabetes. But doctors at La Fe University and Polytechnic Hospital in Valencia, Spain, recently found that when sleep apnea in elderly patients was treated, their odds of cardiovascular death returned to normal.
