Abstract

We conducted a prospective investigation of the effect of coffee consumption on coronary heart disease in 1130 male medical students who were followed for 19 to 35 years. Changes in coffee consumption and cigarette smoking during follow-up were examined in relation to the incidence of clinically evident coronary disease in comparisons of three measures of coffee intake — base-line intake, average intake, and most recent intake reported before the manifestation of coronary disease. Clinical evidence of coronary disease included myocardial infarction, angina, and sudden cardiac death. In separate analyses for each measure of coffee intake, the relative risks for men drinking five or more cups of coffee per day, as compared with nondrinkers, were approximately 2.80 for all three measures in the univariate analyses (maximum width of 95 percent confidence intervals, 1.27 to 6.51). After adjustment for age, current smoking, hypertension status, and base-line level of serum cholesterol, the estimated relative risk for men drinking five or more cups of coffee per day (using the most recent coffee intake measure), as compared with those drinking none, was 2.49 (maximum width of 95 percent confidence interval, 1.08 to 5.77). The association between coffee and coronary disease was strongest when the time between the reports of coffee intake and the coronary event was shortest. These findings support an independent, dose-responsive association of coffee consumption with clinically evident coronary heart disease, which is consistent with a twofold to threefold elevation in risk among heavy coffee drinkers. (N Engl J Med 1986; 315:977–82.), Coffee consumption has long been suspected to be a contributing factor in the development of coronary heart disease, but strong, independent risks associated with coffee drinking have not yet been documented in well-designed prospective studies. Indeed, early case–control studies linking coffee intake to myocardial infarction1,2 have not been consistently supported by several relevant case–control3 4 5 6 and prospective7 8 9 10 11 12 13 investigations with diverse design features. Nevertheless, it has not been possible to exclude coffee drinking as a potential coronary risk factor because of important methodologic differences among the various studies. In addition, recent epidemiologic evidence linking heavy coffee consumption to elevations in total serum…
