risk of a heart attack, a study says.
Environmental noise, such as traffic, increased heart attack risk
twofold to threefold, a German study in the European Heart Journal
Risk appeared to be related to how loud rather than how annoying the
noise was, so current noise safety levels may need to be stricter,
say the authors.
Experts urged people not to be alarmed, saying more work was needed.Bad for hearts
Lead researcher Dr Stefan Willich, from the Charité University
Medical Centre in Berlin, said: "We seem to be looking at a
threshold at which risk occurs and remains constant above this, and
this appears to be around 60 decibels."
Sixty decibels is the level of noise typically experienced, for
example, in a busy large office.
The researchers compared over 2,000 heart attack patients with over
2,000 control patients admitted to trauma and general surgery
departments in Berlin between 1998 and 2001.
Chronic noise exposure was associated with a mildly to moderately
increased risk of heart attack.MURAD ALI BANAAga Khan University,Phone office: (92 21) 486-4759 (working days only)After office hours:Residence: (92 21) 663-2019; Cell: 0334-3056757
