Changes of Ambulatory Blood Pressure Monitoring in High Altitude Hypertension

Abstract

Objective To research the characteristic and changing regulation of ambulatory blood pressure monitoring in high altitude hypertension.Methods The builders in plain entered into elevation 4 800 m area after they were examined normal by medicine,36 person of them who had high altitude hypertension adoped standard ambulatory blood pressure monitoring.Results The elevation of diurnal blood pressure and diastolic pressure is of great value in high altitude hypertension,the percentage of the diastole high altitude hypertension is higher than systole high altitude hypertension(P0.01),its circadian rhythm is curve like ladle shape,but the rate of nocturnal blood pressure's decreasing is still less than 10%,the heart rate has positive related relation with the systolic pressure,diastolic pressure,mean arterial pressure and the heart rate-blood pressure product(all P0.01).Conclusion The body consuming oxygen degree has influence on dynamic rhythm of the high altitude hypertension greatly,it is also to say that it is related to the hypoxia pressure reaction,its focal point of prevention and cure should still be put into decreasing oxygen consuming and amliorativing the hypoxic state.
