Values are given as the mean ± SD, No. (%), or median (IQR). AHI = apnea-hypopnea index; HDL = high-density lipoprotein; IQR = interquartile range; LDL = low-density lipoprotein; LVEF = left-ventricular ejection fraction measured within 1 wk after myocardial infarction; MI = myocardial infarction; minSao2 = nocturnal nadir oxygen saturation; OSA = obstructive sleep apnea; PCI = percutaneous coronary intervention; T90Sao2 = percentage of total sleep time associated with oxyhemoglobin saturation ≤ 90%.
a
P < .016, no OSA vs mild OSA.
b
P < .016, no OSA vs moderate to severe OSA.
