43% of heart attacks go undiagnosed, research claims

OVER 40% of heart attacks may be going undiagnosed at the time they occur, research suggested yesterday.

A Dutch team assessed more than 4,000 men and women over the age of 55 to see if any had suffered a heart attack which went undiagnosed when it happened.

They estimated that 43% of heart attacks had been clinically unrecognised.
