Application of 24h ambulatory blood pressure monitoring in aged patients with hypertension / 心血管康复医学杂志

ABSTRACT

Objective: To explore application of 24h ambulatory blood pressure monitoring (ABPM) in aged patients with hypertension. Methods: A total of 223 aged patients with hypertension treated in our hospital from Feb 2013 to Feb 2015 were selected. According to age, patients were divided into young age group (60～79 years, n=137) and advanced age group (≥80 years, n=86). Another 80 normotensive aged people undergoing physical examination in our hospital simultaneously were regarded as healthy control group. The 24h systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP) were measured and compared between three groups. Results: Ambulatory blood pressure compared with healthy control group, there were significant rise in 24h mean blood pressure (BP) [24hSBP (117. 63±11. 53) mmHg vs. (132. 04±11. 23) mmHg vs. (144. 26±12. 87) mmHg], daytime BP [dSBP (119. 85±13. 20) mmHg vs. (134. 26±13. 52) mmHg vs. (146. 83±10. 64) mmHg]and nighttime BP [nSBP (115. 48±9. 74) mmHg vs. (128. 76±10. 85) mmHg vs. (141. 67±13. 42) mmHg]in young age group and advanced age group (P＜0. 05 or＜0. 01). Compared with young age group, there were significant reductions in 24h DBP, dDBP and nDBP, and significant rise in 24h SBP, dSBP, nSBP, 24h PP, dPP and nPP in advanced age group (P＜0. 05 or ＜0. 01). Conclusion: The 24h ABPM can effectively display the blood pressure abnormal fluctuations in aged patients with hypertension, and the higher age is, the greater blood pressure abnormal fluctuation is.
