Coffee May Trigger Heart Attacks in Some People

New research is suggesting that coffee can trigger heart attacks in some people, within an hour. The report, which comes in the September issue of Epidemiology, says that those highest at risk are "light" coffee drinkers (those who drink only 1 cup a day). Other people at risk include inactive, couch potato types.

Based upon these findings, if you find yourself in one of these highest risk factors, you may want to consider quitting coffee completely.

It has long been demonstrated that caffiene causes short term increases in blood pressure, and also activity in the nervous system. Both of these conditions can contribute to a heart attack.
