Abstract:
Objective To explore if there is a difference in blood pressure in left and right extremities.Methods A total of 20164 adults who took part in health check-up at Health Examination Center of Chinese PLA General Hospital between December 2009 and August 2011were enrolled in this study.Age,height and body weight were recorded,and blood pressure in extremities was measured in synchronous way by using an arteriosclerosis detector.Results (1) Blood pressure in upper left extremity was slightly higher than that in upper and lower right extremity ( all P =0.0001).( 2 ) Difference in diastolic blood pressure in upper left and right limbs in females (2.1±6.7) mm Hg(1mm Hg =0.133 kPa) was more significant than that in males (1.4 +6.5 ) mm Hg ( P =0.0000).In males,difference in systolic blood pressure between two lower extremities ( 2.3 ± 9.6 )mm Hg was more significant than that in females (1.9 ±13.4) mm Hg ( P =0.0225 ).( 3 ) The above mentioned differences were found in low or normal weight and over-weight/obesity populations,which was not correlated with body mess index.(4) The difference of diastolic blood pressure in left and right limbs of relatively taller adults ( ＞170 cm) was more significant than that in shorter populations ( ＜170 cm ) (P =0.001).Conclusion The differences in blood pressure in left and right extremities do exist.
