Many studies have been conducted concerning the relationship between drinking coffee and heart disease. Many of the test results were conflicting. Several reports stated that there was no connection between drinking coffee and heart disease. However, we found two studies where there was a direct connection between drinking coffee and getting heart disease. One of the problems with coffee is that it contains caffeine. Caffeine is a stimulant.

The first study started in 1957 and continued into the 1960's. This study took place in Chicago and was called the "Western Electric Study". Scientists surveyed over one thousand men while they drank coffee. The scientists observed that there was less heart disease in men who drank three or less cups of decaffeinated coffee per day. Scientists also noticed that there was more disease in men who drank five cups or more of decaffeinated or moderate caffeine coffee. The heart disease death rate was highest in men who drank more than five cups of regular coffee a day. Regular coffee has caffeine.

The second study, "The Boston Collaborative Drug Surveillance Program", took place in the 1970's. These scientists found a higher occurrence of coffee drinking among patients who had been hospitalized for heart attacks.

Many people in America have started drinking decaffeinated coffee which means the ninety-seven percent or more of its naturally occurring caffeine has been removed.
