Obstructive sleep apnea (OSA), a condition that impedes normal breathing during sleep, can lead to an increased risk of cardiovascular disease and death, according to a new study. In the study, 1 645 participants had their blood tested and underwent a sleep study to evaluate the effect of OSA on high intensity troponin T, a marker for early damage to heart muscle, and peptide, a marker for increased ventricular wall stress. No participants suffered from coronary heart disease or heart failure at the beginning of the study. The results? Researchers found that severe OSA was linked to higher troponin T levels at baseline. After a median follow-up of 12.4 years, there were 222 total deaths, 122 new cases of heart failure and 212 new cases of coronary heart disease. Within each OSA level, higher troponin T levels were associated with higher risk of all three conditions, especially heart failure. Protect your heart with these 5 New Rules for a Healthy Heart
