One in 100 healthy people carries heart-condition gene

British researchers say 1% at risk of heart failure under abnormal stress, such as pregnancy or alcoholism

Researchers at Imperial College London and the MRC Clinical Sciences Centre say 1% of the population are at risk from heart failure when the organ is placed under abnormal stress - such as through pregnancy or alcoholism - even if they appear otherwise healthy.
