Sleep Apnea and Cardiac Injury

 
A recent study of 136 patients who had an  acute myocardial infarction (MI) suffered less severe cardiac injury because of a potentially complex relationship between obstructive sleep apnea (OSA) and coronary artery disease.

Our study demonstrates that patients with sleep apnea have less severe cardiac injury during an acute non-fatal MI when compared to patients without sleep apnea. This may suggest a cardioprotective role of sleep apnea during acute MI via ischemic preconditioning,” the authors write. “This study highlights the potentially complex relationship between OSA and coronary artery disease.”

During this study , see http://link.springer.com/article/10.1007/s11325-012-0770-7 the link between obstructive sleep apnea and Troponine-T levels were assessed. 35%  of the patients had sleep apnea and 77% had sleep disorders.
