Abstract
Objective: Comparison between the central and brachial blood pressure values in elderly patients treated in A1 Department, 108 Military Central Hospital. Subject and method: This prospective, described and cross-sectional study, assessed 120 elderly patients, selected in the period from June 2017 to August 2017, compared central and brachial SBP using a Centron cBP301 (Centron Diagnostis, UK). Result: 120 patients in the study, with an average age of 73 ± 7 years, men (100%), artery system hypertension (50%). Brachial systolic pressure (bSP) is higher than central systolic pressure (cSP) in patients with hypertension and normal blood pressure (153 ± 17mmHg versus 140 ± 17mmHg and 120 ± 11mmHg with 108 ± 12mmHg, p<0.05). There is no difference in Δ(bSP-cSP) between hypertensive and normal blood presure groups (12 ± 6mmHg versus 12 ± 7mmHg). This difference increases with age. There is a similarity between central diastolic pressure and brachial diastolic pressure in both hypertensive and normal blood pressure (87 ± 11mmHg versus 88 ± 11mmHg and 74 ± 8mmHg vs 75 ± 8mmHg). Δ(bSP-cSP) is positive correlated with age, height, negative correlated with heart rate. Conclusion: Brachial systolic pressure is higher than central systolic pressure in patients with hypertension and normal blood pressure. There is no difference in Δ(bSP-cSP) between hypertensive and normal blood pressure groups. Δ(bSP-cSP) is positive correlated with age, height and negative correlated with heart rate.
