RT Journal Article SR Electronic T1 Role of precision medicine in obstructive sleep apnoea JF BMJ Medicine JO bmjmed FD BMJ Publishing Group Ltd SP e000218 DO 10.1136/bmjmed-2022-000218 VO 2 IS 1 A1 Yu Liu A1 Ali Abdul Ghafoor A1 Mohammadreza Hajipour A1 Najib Ayas YR 2023 UL http://bmjmedicine.bmj.com/content/2/1/e000218.abstract AB Obstructive sleep apnoea is a substantial clinical and public health problem because it contributes to harmful effects on quality of life, daytime symptoms, road traffic incidents, and cardiometabolic disease. Increasingly, obstructive sleep apnoea is recognised as a heterogeneous disease, and patients have varied susceptibility to long term complications and different responses to treatment. This narrative review summarises the current knowledge of precision medicine in obstructive sleep apnoea, particularly the role of symptom clusters, polysomnogram phenotypes, physiological endotypes, and circulating biomarkers in defining subtypes. In the near future, the prognostic accuracy of these measures in predicting long term complications in obstructive sleep apnoea will likely be improved, together with better matching of treatments to disease subtypes.
