    But Heart Disease Risk Still Affected by Many Other Factors

    June 17, 2005 - Though several studies have shown that coffee may actually be good for you, new research shows that too much java may be bad for some coffee lovers' hearts.

    For a nation fueled by Starbucks, studies suggesting that coffee drinkers may be at decreased risk for several major diseases, including Parkinson's and diabetes, is welcome news.

    WebMD even recently reported on two studies from The Journal of the National Cancer Institute showing that coffee may significantly lower the risk of colon and liver cancers coffee may significantly lower the risk of colon and liver cancers.

    But there is also evidence that coffee may increase the risk of heart disease for some coffee may increase the risk of heart disease for some, and a new study from Greece seems to bolster the claim.

    Researchers from the University of Athens found that coffee drinkers had more stiffness of the major blood vessel of the body than non-coffee drinkers. Decreased elasticity of major blood vessels is a risk factor for developing heart disease like heart attack and stroke.

    The findings are reported in the June 1 issue of the American Journal of Clinical Nutrition.

    The researchers had already linked coffee drinking to increased indicators of inflammation, one of the key mechanisms to the development of heart disease. And they have also reported that combining coffee with cigarette smoking seems to be much worse for the heart than smoking alone.

    "The evidence regarding coffee is far less conclusive than it is for smoking," study researcher Charalambos Vlachopoulos, MD, tells WebMD. "But it still might be prudent for people who drink more than three cups of coffee a day to cut down, especially if they have high blood pressure or other risk factors for heart disease."

    The Research

    Previous studies evaluating coffee's role in promoting high blood pressure and heart disease have been conflicting. Though some suggest a strong link, others have found no link at all or even a health benefit to coffee drinking.

    The latest research by Vlachopoulos and colleagues included 228 healthy adults whose average age was 41. The researchers used food-frequency questionnaires to determine how much coffee each study participant drank. They took into account whether participants drank instant coffee, brewed coffee, Greek-type coffee, cappuccino, or filtered coffee. They analyzed the data to account for each cup of coffee containing 80 milligrams of caffeine.
