Enhanced External Counterpulsation Treatment Has No Lasting Effect on ABP

BACKGROUND:

Enhanced external counterpulsation (EECP) has been reported to reduce blood pressure (BP) using clinic BP readings. The aim of this study was to assess the effect of a course of EECP on BP using ambulatory BP (ABP) measurements.

HYPOTHESIS:

EECP has a lasting BP lowering effect.

METHODS:

Patients referred for EECP due to refractory angina pectoris were consecutively included in the study. The ABPs were measured for 24 hours using a Spacelabs Ultralite 90217 device at 5 time points during the study period: 2 months before the EECP course, just before the EECP course, just after the EECP course, and at 3 and 12 months after EECP. Antihypertensive medication was held constant during the study period. Changes in BP were tested by repeated measures analysis.

RESULTS:

Fifty patients were included in the study. The mean age was 63 years, and 72% were male. The Canadian Cardiovascular Society Angina Grading Scale class improved from a mean of 2.6 to 1.5. The mean daytime ABPs were 114/69, 114/70, 115/71, 114/70, and 116/71 mm Hg and the mean nighttime ABPs were 107/63, 108/63, 106/62, 108/63, and 107/62 mm Hg at 2 months before the EECP course, just before the EECP course, just after the EECP course, and at 3 and 12 months after EECP, respectively (all P > 0.10). Further, when controlling for quartiles of baseline ABP level, no significant change in ABP was found.

CONCLUSIONS:

Enhanced external counterpulsation treatment has no lasting effect on ABP.

「體外反搏治療並未對 動態血壓 (ABP)有持久的降壓效應」

背景

據報導,體外反搏治療(EECP)可以通過臨床血壓測量降低血壓(BP)。本研究旨在使用 動態血壓 (ABP)測量評估EECP療程對血壓的影響。

假設

EECP具有持久的降壓效應。

方法

連續納入因難治性心絞痛而接受EECP治療的患者。使用Spacelabs Ultralite 90217設備在研究期間的5個時間點進行24小時的ABP測量:EECP療程前2個月、EECP療程前、EECP療程後、EECP後3個月和12個月。研究期間,抗高血壓藥物保持不變。通過重複測量分析檢測血壓的變化。

結果

共納入50名患者,平均年齡為63歲,其中72%為男性。加拿大心血管學會心絞痛分級表的等級由平均2.6改善至1.5。白天平均ABP值為114/69、114/70、115/71、114/70和116/71 mm Hg,夜間平均ABP值為107/63、108/63、106/62、108/63和107/62 mm Hg,分別對應於EECP療程前2個月、EECP療程前、EECP療程後,以及EECP後3個月和12個月。此外,在控制基線ABP水平的四分位數的情況下,未發現ABP有顯著變化。

結論

體外反搏治療對ABP沒有持久的影響。
