Insights
Enhanced external counterpulsation (EECP) significantly improved heart function and prognostic markers in patients with coronary artery disease (CAD) and heart failure (HF). This noninvasive therapy offers a safe and effective treatment option for improving clinical outcomes in these patients.
Area of Science:
- Cardiology
- Noninvasive Cardiovascular Therapies
Background:
- Coronary artery disease (CAD) and heart failure (HF) are significant cardiovascular conditions.
- Enhanced external counterpulsation (EECP) is a noninvasive treatment option for patients with CAD and HF.
Purpose of the Study:
- To investigate the clinical effects of EECP therapy in patients with symptomatic CAD and chronic HF.
- To determine if EECP therapy impacts prognostic markers of HF.
Main Methods:
- Prospective cohort study design.
- Enrolled 68 patients with symptomatic CAD and chronic HF; 47 received EECP, 21 served as controls.
- Statistical analysis included t tests, Mann-Whitney U, Chi-square, and Fischer exact tests.
Main Results:
- EECP significantly improved New York Heart Association functional class and left ventricular ejection fraction.
- EECP therapy led to significant improvements in B-type natriuretic peptide and uric acid levels.
- Post-intervention analysis showed improvements in free-T3/free-T4 ratio and mitral annular E velocity with EECP.
Conclusions:
- EECP treatment significantly enhances clinical parameters in patients with symptomatic CAD and chronic HF.
- The therapy positively affects biochemical markers, many of which are prognostic indicators for HF.
- EECP demonstrates efficacy in improving prognostic markers, supporting its role in managing symptomatic CAD and chronic HF.
Objective:
Enhanced external counterpulsation (EECP) is a noninvasive treatment that is proven safe and effective in patients with coronary artery disease (CAD) and heart failure (HF). The aims of this study are to investigate the clinical effects of EECP therapy in patients with symptomatic CAD and chronic HF, and to find out an answer to the question: Does EECP therapy have any effect on the prognostic markers of HF?
Methods:
This study was designed as a prospective cohort study. A total of 68 consecutive patients with symptomatic CAD and chronic HF referred to EECP therapy were enrolled in this study between November 2007 and December 2010; 47 patients (39 males and 8 females, 65 ± 7, years), have undergone EECP treatment, and 21 patients (20 males and 1 female, 62 ± 10 years), who did not want to participate in the EECP program comprised the control group. Statistical analysis was performed using t tests for dependent and independent samples, Mann-Whitney U test, Chi-square and Fischer exact tests.
Results:
EECP therapy resulted in significant Improvement in post-intervention New York Heart Association functional class (p<0.001), left ventricular ejection fraction (p<0.001), B-type natriuretic peptide levels (p<0.003), uric acid levels (p<0.05), free-T3/free-T4 ratio (p<0.034) and mitral annular E (p<0.05) velocity, compared with baseline, a finding not evident in the control group.
Conclusion:
EECP treatment significantly improved clinical and some biochemical parameters, which are mostly prognostic markers in patients with symptomatic CAD and chronic HF.
