Heart attack risk 'more inherited than stroke'

Heart attack risk 'more inherited than stroke'
27th July 2011

People are much more likely to inherit a vulnerability to heart attack than to stroke, according to new research.

A study published in journal Circulation: Cardiovascular Genetics revealed that among men with acute heart ailments, 30 per cent had one parent who had experienced a heart attack and 21 per cent had at least one sibling who had had a heart attack.

In addition, seven per cent had two or more siblings who had experienced the cardiovascular conditions while five per cent had two parents with heart attack.

Comparatively, among patients with stroke or transient ischemic attacks, 21 per cent had one parent to who had had a stroke, while two per cent had two parents.

Senior author Peter M Rothwell, of Oxford University, said: "We found that the association between one of your parents having a heart attack and you having a heart attack was a lot stronger than the association between your parent having a stroke and you having a stroke."

This follows research published in journal Stroke which found that optimistic people could be at a lower stroke risk than their more negative peers.
