According to World Health Organization estimates, 16.7 million people die of cardiovascular diseases each year. By the year 2010, it is estimated that cardiovascular disease will become the leading cause of death in developing countries and by 2020 it will contribute to nearly 25 million deaths worldwide. Although therapies including drugs, lifestyle modification and revascularisation procedures have been demonstrated in clinical trials to be beneficial, they are under-utilised. Paradoxically, in spite of the under-use of evidence-based therapies, patients actively seek complemen- tary and alternative medicine (CAM) treatments. While many alternative therapies involve oral vitamin and mineral supple- ments that are unlikely to cause harm, chelation therapy is one of the most aggressive and intensive CAM modalities.
