Abstract

Enhanced external counterpulsation (EECP) is a noninvasive, pneumatic technique that provides favourable effects in patients with coronary artery disease. The objective of this study was to describe the long-term effect of EECP on endothelial function in patients with ischaemic cardiomyopathy. The study was performed in 15 patients with ischaemic cardiomyopathy. All subjects were treated with EECP 1-h per day, 5 days a week, over 7 weeks (totally 35h). Endothelium-dependent and -independent relaxation was assessed by flow-mediated dilation (FMD) and nitroglycerine-mediated dilatation (NMD). In each patient, FMD and NMD measurements were performed before, at midcourse (day 17th) and after completion of EECP course (day 35th). In addition, FMD index was assessed 1 month after completion of EECP therapy. Results showed that EECP was associated with a significant improvement in FMD index after 35 hours of EECP (10.95+/-4.1% vs. 7.40+/-4.9% for baseline, p<0.05). NMD index didn't significantly alter during the EECP therapy. Also, 1 month after completion of EECP, FMD index returned to baseline (7.51+/-4.4% vs. 7.40+/-4.9%, respectively, p<0.05). EECP acutely improved endothelial function in ischaemic cardiomyopathic patients. Howeve...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Antianginal Drugs: Mechanisms of Action

Antianginal drugs, including nitrates, beta-blockers, and calcium channel blockers, are used in the treatment of angina pectoris. Here is the latest research on their use and their mechanism of action.
