Efficacy of enhanced external counterpulsation: our experience

Aims: Enhanced external counterpulsation therapy is a non-invasive, non-pharmacological outpatient treatment option for refractory angina pectoris. Our aim is to evaluate its efficacy in Nepalese refractory angina pectoris patients. Materials and methods: It was single centre prospective study conducted from 2010 August to 2013 December. All thirty one (n=31) consecutive patients, referred for and received 35 hours of treatment were included in this study. The distance covered in six minute walk test before and after the treatment was recorded and compared. Patients were followed each with the questionnaires about their anginal symptoms before and after the treatment. Results: In our study 19(61.3%) were male and 12(38.7%) female. The mean age was 65.7±9.3 years. Most patients had multi vessel disease. Twelve patients had previous history of revascularization. In 6 minute walk test there was significant difference in mean distance covered before and after the treatment. Most patients experienced decrease in the angina symptom. They had decreased in severity and frequency of angina, resulting in decreased use of sublingual nitrates. Conclusion: EECP can be safe and effective treatment option for patients with RAP.
