Abstract
Objective To study the changes and clinical significance of 24 hour ambulatory blood pressure monitoring (ABPM) in patients with congestive heart failure (CHF). Methods 57 patients with CHF were divided into three gropus: group A(n=17, heart function class Ⅱ), group B(n=19, heart function class Ⅲ), group C (n=21, heart function class V). According to different causes, these patients were divided into group D (n=19, dilated cardiomyopathy) and group E(n=41,non-dilated cardiomyopathy). All patients were monitored by 24 hour ABPM. Mean systohc pressure, night systolic pressure drop rate (nsBPR) and 24 hours mean systolic pressure variability (24 h sBPV) were compared. Results Mean systolic pressure in group C were slightly lower than those group A and group B. But there were not significant differences among group A, B and C (P>0.05). Mean systolic pressure in group D were significantly lower than that in group E (P<0.05). The nsBPR in group A, B and C were 58. %, 88.3%, and 95.2%. There were significantly differences in nsBPR between the group A and B or C (P<0.05 and <0.01). The 24 h sBPV in group A, B and C was 9.7,8.8 and 8.7. There were significantly differences between group A and group B or C (P<0.01). Conclusion Mean systolic pressure with CHF decreases. Day and night rhythms of blood pressure with CHF were reduced or disappeared. 24 h sBPR was reduced. These changes were positively correlated with the degree of CHF.关键词
