PS 02-55 PREVALENCE OF WHITE COAT HYPERTENSION IN MEDICAL PERSONNEL

Objective: To study the prevalence of White Coat Hypertension in Medical personnel through ambulatory blood pressure monitoring, to study the Determinants of White Coat Hypertension in Medical personnel and to study the Blood pressure variability patterns (Dipping status) in Medical subjects. Design and Method: In this study, we initially explained the whole procedure in detail including benefits of this screening study to the subjects and take their consent in written. Then we took clinical blood pressure of medical subjects with a properly calibrated barometric sphygmomanometer of calibration between 0–300mmHg. Two readings each by a trained nurse and then by us were taken at a 5 minute interval and average of the readings was noted. Results: Comparing the mean ABPM parameters of two groups, t test revealed significantly different and higher day time SBP (118.78 ± 11.74 vs. 133.29 ± 13.65, t = 3.92; p < 0.001) and DBP (68.84 ± 8.15 vs. 82.90 ± 5.99, t = 6.28; p < 0.001) both in hypertensive group as compared to WCH group. Further, the day time SBP and DBP both found 10.9% and 17.0% higher respectively in Hypertensive group as compared to WCH group. Similarly, the night time SBP (107.36 ± 10.18 vs. 130.29 ± 10.43, t = 7.48; p < 0.001) and DBP (62.07 ± 6.65 vs. 80.22 ± 5.23, t = 9.79; p < 0.001) both in hypertensive group was also found significantly different and 17.6% and 22.6% higher respectively as compared to WCH group. Conclusions: High percentage of Non- dippers were found to be present in White coat hypertensive group. However significant association of non dippers with either White coat hypertensive's or true hypertensives was not seen. Reverse Dippers were found to be significantly associated with true hypertensive's (23.5%).
