• 1 other identifier: 202510163RINE
• Study Type: observational
• Target: 60
• Locations: 0 countries
• Sites: N/A

Brief Summary

The goal of this observational cross-sectional study is to assess the prevalence of left ventricular diastolic dysfunction and identify associated risk factors in health-care workers of various ages and both sexes. 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.
