Registry of Obstructive Sleep Apnea in Hypertensive Patients in China

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the adherence to continuous positive airway pressure (CPAP) therapy in patients with hypertension and obstructive sleep apnea syndrome (OSAS) across multiple centers in China. It will assess both short- and long-term adherence to CPAP and identify predictors that influence this adherence. Additionally, the study will explore the relationship between CPAP adherence and various health outcomes, including blood pressure control and the incidence of cardiovascular events. The research is observational and involves patients who have been diagnosed with hypertension and suspected OSAS.
