Determinants and Evolution of Obstructive Sleep Apnea Syndrome After Myocardial Infarction

Cardiorespiratory monitoring was performed within 72 hours from the occurrence of an acute coronary syndrome. An elevated rate of moderate-severe obstructive sleep apnea syndromes was detected, which was related to the severity of the coronarographic score. Twenty-three patients underwent a new polygraphic study 3 months after the acute event. All showed a reduced number of hypo-apnoeic events. The OSA severity at baseline did not predict a worse cardiac function at 3 months.
