Cardiovascular effects of coffee: is it a risk factor? Sudano I(1), Binggeli C, Spieker L, LÃ¼scher TF, Ruschitzka F, Noll G, Corti R. Author information: (1)Department of Internal Medicine, Cardiology Unit, University Hospital ZÃ¼rich, ZÃ¼rich, Switzerland. Intake of coffee, one of the most common beverages worldwide, is often reported as a cardiovascular risk factor; however, definitive data are lacking. Acute intake of coffee or beverages containing caffeine can increase blood pressure, heart minute volumes, and cardiac index, as well as activate the sympathetic nervous system in nonhabitual coffee drinkers. Interestingly, this is not observed in habitual coffee drinkers.
