Hypothesis
The study aims to assess the long-term outcome of EECP treatment in relieving angina in patients with chronic refractory angina pectoris.
Conclusion
EECP is a safe treatment for highly symptomatic patients with refractory angina, with beneficial effects sustained during a 12-month follow-up period.
Supporting Evidence
- 79% of patients improved their CCS class after EECP treatment.
- 73% of patients who improved did so by one CCS class, while 22% improved by two CCS classes.
- The improvement in CCS class persisted for 12 months after treatment.
Takeaway
EECP is a treatment that helps people with severe chest pain feel better, and it keeps helping them for a long time after the treatment ends.
Methodology
55 patients were treated with EECP, and their CCS class, medication use, and clinical events were recorded before, after treatment, and at six and twelve months follow-up.
Potential Biases
The improvement in CCS class could be influenced by the special attention given to patients during follow-up.
Limitations
The study lacks a control group, which means a placebo effect cannot be excluded.
Participant Demographics
55 patients (47 male, 8 female) aged 45-89 with chronic stable refractory angina.
