Patients reporting nocturnal asthma-like symptoms may really have obstructive sleep apnoea, Australian research suggests.

The findings have led the authors to call for those who have woken at least once in the past 12 months with a feeling of tightness in the chest, shortness of breath or asthma together with clinical features of obstructive sleep apnoea (OSA) to be screened for the disease.

The researchers gave lung-function tests and questionnaires to nearly 800 people (mean age 50) in the Tasmanian Longitudinal Cohort Study — a cohort that includes asthma patients.

The study found 33% of the cohort were at high risk for OSA, judged by the results on the STOP-bang questionnaire.
