Objective  To explore the best mode of blood pressure monitoring by comparing the correlation of deferent kinds of blood pressure variability with arterial stiffness. Methods  This study was conducted among 140 hypertensive patients in Wuhou Strict, Chengdu. Baseline data was collected including demographic data, biochemical examination and brachial-ankle pulse wave velocity (baPWV) measurement and so on. A consecutive home blood pressure was also gained by the individuals themselves and the clinical blood pressure was also recorded during the visit. The correlation between baPWV and the blood pressure variability were tested. Results  The blood pressure variability measured at home in the morning was independently correlated with baPWV (r=0.313, P=0.011), the blood pressure variability measured at home in the evening was also independently correlated with baPWV (r=0.241, P=0.042), and day-to-day morning blood pressure variability measured at home was correlated with baPWV (r= 0.269, P=0.030). The correlation of month-to-month blood pressure variability and blood pressure variability gained at clinic room with baPWV was not significant (P>0.05). Conclusion  In the monitoring of blood pressure variability in hypertensive patients, the blood pressure variability monitoring at home is better than that at the clinic room; and monitoring in the morning is better than that in the evening.
