Coffee can often trigger heart attack
Indo-Asian News Service
New York, Aug 16 (IANS) A cup of coffee may trigger a heart
attack in some people within an hour of drinking it, reveals a
new study.
Ana Baylin and colleagues at the Brown University School of
Medicine in Providence, Rhode Island, studied 503 cases of
non-fatal heart attacks in Costa Rica. They
surveyed participants about their coffee consumption in the
hours and days before their heart attack and also studied their
lifestyle and medical history.
The researchers found that for people with multiple risk factors
for a heart attack and those who have a sedentary lifestyle, a
cup of coffee could be the final straw, reported
the online edition of health magazine WebMD.
The researchers suggest that caffeine causes short-term increase
in blood pressure and sympathetic nervous activity that could
trigger a heart attack. "It can trigger a heart
attack within an hour in some people," said Baylin.
They said moderate coffee drinkers (those who consumed two-three
cups a day) raised their risk of having a heart attack by 60 per
cent.
.
Light drinkers increased their risk of heart attack by more than
four times with one cup, the study observed. Little effect was
seen among heavy coffee drinkers (those who
drank four or more cups per day).
Further, coffee drinkers who have three or more risk factors for
heart disease more than doubled their risk of sustaining a heart
attack after downing a cup.
Although the study was conducted in Costa Rica, the researchers
say the results are relevant to people who have similar caffeine
habits.
