In patients with intractable angina who were symptomatic after medical and invasive strategies, several novel techniques are considered including EECP. In patients with refractory angina due to coronary anatomy specific information, CABG or PCI are also up despite anti-ischemic drug therapy are still symptomatic, other treatments including EECP is used. EECP produces an acute hemodynamic effect that is presumed to be similar to that produced by the invasive intra-aortic balloon pump. By applying a series of compressive cuffs sequentially from the calves to the thigh muscles upon diastole and rapidly deflating the cuffs in early systole, an increase in diastolic and decrease in systolic pressure is created. The purpose of this study was finding relationship between the therapeutic effects of enhanced external counterpulsation on refractory angina in patients, unsuitable for invasive interventions.Materials & Methods: In an Intermediary study, 50 consecutive patients (34 male, 16 female) were treated with EECP and followed for one year post treatment. Canadian cardiovascular society (CCS) class was analyzed, and medication and adverse clinical events were assessed prior to EECP, at the end of the treatment, and at 1 and 12 months thereafter. Any differences in background factors were recorded and analyzed.Results: The mean age of the 50 patients of this study was 62.18±8.67 years. A significant difference was found in score of life quality questionnaire between pre and after EECP treatment (p=0.010). Differences between EF pre and after treatment were significant (p=0.038). Differences between angina severity (CCS Score) pre and after EECP treatment were significant (p SP - 7 EP - 14 AU - Aslan Abadi, Naser AU - Salehi, Rezvaneyeh AU - Alizadeh, Azin AU - Eslamiyan, Fariba AU - Ahmadzadeh Pournaky, Ahmad AU - Taban Sadeghi, mohamad Reza AD - Tabriz University of Medical Sciences, Tabriz, Iran KW - Enhanced external counterpulsation KW - Refractory angina KW - Coronary artery disease UR - http://umj.umsu.ac.ir/article-1-1236-en.html ER -
