Hypothesis
Can the outcome of enhanced external counter pulsation (EECP) treatment for refractory angina pectoris be predicted by analyzing baseline factors?
Conclusion
EECP is a safe and effective treatment for patients with refractory angina pectoris, particularly beneficial for those with severe angina.
Supporting Evidence
- 79% of patients improved at least one CCS class after EECP treatment.
- 61.5% of initial responders maintained improvement at 12 months.
- 29% maintained improvement at 24 months.
- Diabetes and calcium channel antagonists were more common among non-responders.
Takeaway
This study shows that a special treatment called EECP can help people with severe chest pain feel better, especially if their pain is really bad.
Methodology
86 patients were treated with EECP and followed for two years, with assessments of CCS class and medication usage at multiple time points.
Potential Biases
The possibility of mass significance in the analysis of background factors associated with treatment failure cannot be ruled out.
Limitations
The study lacks a control group, which may affect the interpretation of the results due to potential placebo effects.
Participant Demographics
70 male and 16 female patients, with a mean age of 66 years.
