ABSTRACT Background: BPV is one of the recognized risk factor for different types of cardiovascular diseases. Circadian patterns of blood pressure and heart rate gets alterd as a function of job type. Night shift workers have altered circadian pattern of blood pressure and heart rate. Due to this variation, night shift worker suffers from various cardiovascular disorders and hormonal disturbances. Methods: The Present Study Was Aimed to Investigate the Effects of Circadian Blood Pressure and Heart Rate in males as a function of work type on 24 hours BP/HR .Total 57 healthy professionals, aged 20-55 year, performing day and night shift duties were taken. Out of 57 males, eight were shift workers performing 10 hrs job , eighteen were students ( hrs) and thirty one were day workers(8hrs). Circadian Mesor, amplitude and Acrophase of SBP, DBP, MAP, DP and Heart Rate in males were calculated. Results: Ambulatory BP and HR were recorded at every 30 min intervals in day time and each hour in night time synchronically during their duties. Highly Significant difference was found in double amplitude (2DA) of blood pressure between night and day shift (p<0.001). In night shift, hyperbaric index (HBI) of mean systolic blood pressure was found to be increased at 12-03 am (midnight) while during day shift, peak was found at 06-09 am. Conclusions: The present study concluded that variabilities in BP may be associated with factor type to some extend.
