Features of ambulatory blood pressure in aged patients with hypertension complicated coronary heart ;disease / 心血管康复医学杂志

ABSTRACT

Objective:To observe features of ambulatory blood pressure in aged patients With hypertension complicated coro-nary heart disease (CHD)and explore the relationship betWeen abnormal ambulatory blood pressure and coronary athero-sclerosis.Methods:According to coronary angiographic results,a total of 220 aged patients With hypertension (>60 years) Were divided into hypertension+ CHD group (n=124)and single hypertension group (n=96).Both groups received 24h ambulatory blood pressure monitoring (ABPM),24h blood pressure (BP),BP variability,pulse pressure and circadian rhythm of blood pressure Were recorded.Results:Compared With single hypertension group,there Were significant increase in 24h,daytime,nighttime mean systolic blood pressure (SBP),SBP variability [dSSD (14.01±4.26)vs. (17.54± 5.51),nSSD (15.05±4.01)vs. (19.32±3.71)],pulse pressure [dPP (56.66±7.43)mmHg vs. (66.32±13.62) mmHg,nPP (55.71±6.62)mmHg vs. (63.86±7.52)mmHg] (P<0.05 all)and percentage of non-dipper rhythm (60.32% vs.82.45%)in hypertension+CHD group,P<0.01.Conclusion:There are significant increase in systolic blood pressure,SBP variability and pulse pressure,percentages of abnormal circadian rhythm in aged patients With hyper-tension complicated coronary heart disease, these abnormality may be related to occurrence and development of coronary atherosclerosis in aged patients With hypertension.
