The acute electrocardiographic changes during apneic episodes in patients with sleep apnea are well known. Long-term electro-cardiographic changes in these patients are not well studied. We conducted a retrospective case-control study to assess the electrocardiographic changes in African-American patients with established obstructive sleep apnea syndrome (OSA). A significant percentage of patients with OSA had abnormal EKGs as compared to the control group. The effect of sleep apnea on the cardiovascular system is more complex in African-Americans due to higher prevalence of co-morbid conditions. Seventy-three percent of our patients with OSA had metabolic syndrome.
