Why the study?
Although OSA is linked to increased cardiovascular risk and arrhythmia, it has paradoxically been associated with lower short-term mortality in acute cardiac settings, but data in contemporary PCI populations remain limited.
Explores arrhythmia risk in patients with sleep apnea undergoing PCI, suggesting a possible paradox in outcomes.
Obstructive sleep apnea (OSA) is common among patients with coronary artery disease and is associated with obesity, hypertension, diabetes, and heightened sympathetic tone, which increase cardiovascular risk and predispose to arrhythmia. Paradoxically, emerging data from cardiovascular cohorts suggest that patients with OSA and related high-risk phenotypes may exhibit lower short-term mortality in acute cardiac settings, a pattern partly attributed to ischemic preconditioning and the obesity paradox, but data in contemporary PCI populations remain limited.
