Anti-diabetes drugs, which lower blood-sugar levels, increase the risk of heart failure by 14 per cent, say researchers from the University Health Network. This is an average increased risk over placebo, and some raise the risk even higher.
Overall, the drugs have a seven per cent increased risk of heart failure for every kilogram of weight gained on the drug.
The researchers discovered the risk when they analysed 14 drug trials, involving 95,502 diabetic patients. Four per cent of patients suffered heart failure during the lifetime of one of the studies, and nearly 10 per cent had "a major cardiovascular event".
A better strategy is to lose weight, which doesn't have any adverse effect on heart health.
