A new study published in Circulation reveals how changes in the organized cell membrane network of heart muscle leads to heart failure. Colchicine, a drug used for gout treatment, protects normal heart function by reducing microtubule density, while taxol accelerates damage during heart failure.
A systematic review of 49 studies found that patients with heart failure and their families often lack basic knowledge about the condition, leading to confusion, delays in seeking help, and uncertainty about long-term care. This lack of understanding can decimate quality of life and is a major reason seniors end up in emergency rooms.
