The main questions it aims to answer are:

What is the prevalence of diastolic dysfunction among healthcare workers? Which occupational, lifestyle, or clinical factors are associated with abnormal diastolic function in this population?
Researchers will compare health-care workers who dont need night shift with those who have to.
Participants will:
Complete questionnaires regarding demographic information, work schedules, lifestyle factors, and medical history.
Undergo echocardiographic examination to assess diastolic function. Receive basic vital sign by ambulatory blood pressure monotoring.

What does the primary outcome measure?
diastolic dysfunction (time frame: 2026/01~ 2026/12). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
