Introduction: In this study, we aimed to explore the effect of sleeplessness on right heart function in medical employees who have night-shift work.Patients and Methods: Fifty-two employees who work nightshifts were included in this study. Right ventricle tissue Doppler imaging (TDI), myocardial performance index (MPI), tricuspid annular plane systolic excursion (TAPSE) and pulmonary artery stiffness (PAS) were calculated using maximal frequency shift (MFS) and acceleration time (AcT) in addition to routine echocardiographic examination of all individuals.Results: When comparing right ventricular functions before and after a night shift, there was reduction of tricuspid E wave velocity after sleeplessness was determined (p
