Stem cells and cardiac regeneration.

Despite many advances in cardiovascular medicine, heart failure (HF) remains the leading cause of death in developed countries affecting at least 10 million people in Western Europe alone. The poor long-term prognosis of HF patients, and immense public health implications has fuelled interest in finding new therapeutic modalities. Recent observations of the beneficial effect of stem cells on the damaged heart in animal experiments have generated tremendous excitement and stimulated clinical studies suggesting that this approach is feasible, safe, and potentially effective in humans.
