Detailed information on heart cells did not win thanks to new research in nano technology have been able to see how heart failure affects the surface of individual cells of the heart muscle in detail, a technique using nanoscale revisited. The results can lead to improved design of beta-blockers, drugs that can slow the development of heart failure, and improvements in current therapeutic approaches for the treatment of heart failure and abnormal heart rhythms.
