Key result
Obstructive sleep apnea is linked to higher sudden cardiac death risk, potentially driven by ventricular arrhythmias.
Why the study?
Obstructive sleep apnea is increasingly recognized as an independent risk factor for sudden cardiac death, but the mechanism involving ventricular arrhythmias is not well defined.
May inform SCD risk assessment; leaves open whether OSA treatment reduces ventricular arrhythmias or mortality.
Obstructive sleep apnea is a growing problem and it has attracted everyone’s attention due its effect on various chronic medical conditions like atrial fibrillation, insulin resistance, chronic kidney disease and coronary artery disease. There is new evidence associating obstructive sleep apnea with sudden cardiac death as an independent risk factor. The most common rhythm causing sudden cardiac death or arrest is a ventricular arrhythmia. It is possible that the increased risk of ventricular arrhythmia due to obstructive sleep apnea could explain the increased risk of sudden cardiac death in patients with obstructive sleep apnea.

A 2010 study conducted a review in Obstructive sleep apnea. Obstructive sleep apnea was evaluated. Obstructive sleep apnea is associated with an increased risk of sudden cardiac death, which may be explained by an increased risk of ventricular arrhythmias.
