Key result
Severe obstructive sleep apnea affected 36.4% of patients with significant coronary artery disease versus 3.8% without, and higher AHI independently predicted higher SYNTAX scores (B=0.329).
Why the study?
Is obstructive sleep apnea severity associated with greater anatomical complexity of coronary artery disease in patients undergoing coronary angiography?
Is obstructive sleep apnea severity associated with greater anatomical complexity of coronary artery disease in patients undergoing coronary angiography?
No takes yet. Share an insight, caveat, or question.
Obstructive sleep apnea is highly prevalent in patients undergoing coronary angiography and its severity independently predicts the anatomical complexity of coronary artery disease.
Kowalik-Pandyra et al. (2026) studied this question. Severe obstructive sleep apnea affected 36.4% of patients with significant coronary artery disease versus 3.8% without, and higher AHI independently predicted higher SYNTAX scores (B=0.329).
