Multidimensional physiological burden of nocturnal respiratory events improves the prediction of cardiovascular mortality in obstructive sleep apnoea
Obstructive sleep apnoea (OSA) is a prevalent cardiovascular (CV) risk factor, yet the clinical reliance on the apnoea-hypopnoea index (AHI) is increasingly questioned. The AHI is a crude frequency count that ignores the physiological heterogeneity of respiratory events, such as their duration, intensity, and tem...
