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.
