We thank Dr. BaHammam for showing interest in our study.1 Regarding the higher prevalence of obstructive sleep apnea observed in our study when compared with his, there are fundamental differences between the two studies. In the study by BaHammam et al,2 apart from being limited by a much smaller sample size (n = 50), patients with both acute myocardial infarction (n = 34) and unstable angina (n = 16) were included. There was no mention of the treatment administered (ie, revascularization vs medical therapy). On the other hand, all patients recruited into our study had ST-segment elevation myocardial infarction and were successfully treated with primary percutaneous coronary intervention. A direct comparison between the two studies, in our opinion, is inappropriate.
