Abstract： Objective It was designed to investigate the significance of head-up tilt test in medical evaluation of aircrew with hypertension. Methods The 85°head-up tilt test for 20 min was performed in 203 aircrew. The changes in blood pressure and heart rate during head-up tilt test were statistically analyzed according to the groups of aircrew with normal blood pressure(n=178), higher blood pressure(n=15) during head-up tilt and treated hypertension(n=10) respectively. Results During head-up tilt, DBP and pulse rate significantly increased and SBP just increased during the initial period in normal blood pressure group(P<0.01)and the average values were all in the normal limits. The changes in blood pressure and pulse rate during head-up tilt in higher blood pressure group were similar to normal blood pressure group, but the average values of DBP and SBP during the initial period were all higher than the normal maximum limits. The blood pressure and pulse rate were all normal during supine in treated hypertension group, only pulse rate increased significantly(P<0.01)and the increased responses in DBP and SBP disappeared during head-up tilt. Conclusions Aircrew with early hypertension or body postural hypertension could be detected and the treatment effect on hypertension could be evaluated by application of head-up tilt test.
