简要总结

Chronic viral cardiomyopathy is a disease where the cardiac muscle is attacked by a virus and this may result in a reduction in the output of the heart (pump function) thereby causing complaints such as chest pain, shortness of breath and palpitations.

Betaferon (interferon beta-1b) is marketed for the treatment of Multiple Sclerosis already, but until now, it has not been proven whether it is also effective in patients with chronic viral myocardial disease.

This study will be conducted to examine the efficacy and safety of Betaferon in patients with this disease. The aim of the treatment is to eliminate the virus from the heart so that the heart function and clinical status can gradually improve.

详细描述

The study has previously been posted by Schering AG, Germany. Schering AG, Germany has been renamed to Bayer Schering Pharma AG, Germany.

Bayer Schering Pharma AG, Germany is the sponsor of the trial.
