Marathon runner 'died of heart failure', says doctor

The doctor who performed the post-mortem on Claire Squires, who died during last year's London Marathon, has told an inquest that she died of heart failure, likely complicated by the supplement DMAA.

The caffeine-like stimulant was in the runner's drink, and has since been banned in the UK.
