Percutaneous coronary intervention for central sleep apnoea with ischaemic cardiomyopathy.

Central sleep apnoea is often recognized in patients with heart failure. Although the medical treatment to improve cardiac function is effective for sleep apnoea, direct evidence that improved cardiac function ameliorates sleep apnoea has not been reported due to the fact that a particular drug may affect a multitude of organs. We present a chronic heart failure patient with central sleep apnoea whose nocturnal desaturation was improved by percutaneous coronary intervention that resulted in improved cardiac function. This is the first case where percutaneous coronary intervention improved sleep apnoea, suggesting that the improved cardiac function led to amelioration of sleep apnoea.
