Calcium pills increase risk of heart attack
www.gdaguru.com today reports that calcium supplements taken by many older people could be increasing their risk of a heart attack, research shows. 10-08-2010
The study, in the British Medical Journal, said people who took supplements were 30% more likely to have a heart attack. The reason for the increased risk of heart attack is not clear but it is thought the extra calcium circulating in the blood could lead to a hardening of the arteries. Data from 11 trials also suggested the medicines were not very effective at preventing bone fractures. Almost 3m people in the UK are thought to have osteoporosis and many take calcium pills to prevent fractures. The study recommends doctors review their use of calcium supplements for managing osteoporosis. The National Osteoporosis Society said most people should be able to get enough calcium through their diets, rather than reaching for the medicine cabinet.
Dr Alison Avenell, from the University of Aberdeen which did the research with colleagues in New Zealand and the US, said:
"It is a balance of risks - people should consider the risks involved and how they apply to their own circumstances and discuss the matter with their GP." With thanks to www.bbc.co.uk.
