Objective To observe blood pressure variability(BPV) and analyze the correlation between BPV and carotid artery-intima media thickness (CA-IMT) in elderly hypertension. Methods Totally 156 patients with primary hypertension were divided into 3 groups:patients aged 45-59years (48 cases) 60-79 years (52 eases),and 80-94 years (56 cases).24 h ambulatory blood pressure monitoring (24 h ABPM) was used to measure 24 h mean systolic blood pressure (24 hSBP),24 h SBP standard deviation (24 h SBPSD),and to calculate 24 h SBP coefficient of variation (24 hSBP CV).Meanwhile,SBP of daytime (DSBP) and nighttime (NSBP),DSBPSD and NSBPSD were measured,and DSBPCV and NSBPCV were calculated.CA-IMT was examined by ultrasound.Spearman rank correlation coefficient was employed to assess the relationship between above indicators and CA-IMT,age. Results No differences were found in 24 h SBP,DSBP and NSBP among the groups.24 hSBPSD( 14.3 ± 3.1),24 h SBPCV ( 11.5 ± 2.1 ),DSBPSD ( 13.8 ± 3.8),DSBPCV ( 10.7 ± 2.6),NSBPSD (13.4±3.3)of patients aged 80-90 years were higher than those of patients aged 60-79 years (12.2±2.5,10.1±2.0,11.6±2.6,9.5±2.3,11.9±2.8)and patients aged 40-59 years (11.7±2.8,9.4±1.9,10.9±3.1,8.4±1.8,11.6±3.0) (P<0.05).NSBPCVof patients aged 80-90years was increased as compared with patients aged 40-59 years (10.9±2.7 vs.9.6±2.4,P<0.05).24 h SBPSD,24 h SBPCV were associated with CA-IMT and age(r=0.26,0.39;0.28,0.42,all P<0.01). Conclusions SBPSD and SBPCV of 24 h ABPM are higher in very older patient with hypertension and could be the useful markers for assessment of BPV.
