A number of observational and population studies suggest that drinking a moderate amount of coffee may reduce the risk of cardiovascular disease, including certain arrythmias (such as atrial fibrillation), and death from heart attack.

High intakes of caffeinated coffee are also associated with an increased risk of dementia. Get the details, including whether coffee consumption affects risk of high blood pressure and arterial stiffness.
