A new study has revealed that drinking coffee increases heart attack risks in people with high blood pressure. One U.S. expert, cardiologist David Friedman, said, "Patients with known heart disease, who are at elevated risk, should limit their intake of daily caffeine products."
Moderate coffee drinking was defined as one to three cups of the caffeinated beverage per day, while heavy consumption was defined as four or more cups daily. The research team, which was led by Lucio Mos of Hospital of San Daniele del Friuli in Udine, Italy, found that compared to those participants who did not drink coffee, the risk of these events was four times higher among the heavy coffee drinkers and three times higher in moderate coffee drinkers.
Experts note that these study findings are preliminary. Friedman said, "Although some limitations exist with this type of study, this association, especially in heavier coffee drinkers, cannot be totally discounted."
The study was presented in London at the annual meeting of the European Society of Cardiology.
