Dear Matt,

Hello! You are correct--caffeine has a stimulatory effect on cardiac muscle function. From what data that I can find, coffee consumption does not appear to increase the risk for heart attacks (see SA Rosner, Am. J Epidemiology vol. 165, p. 288, 2007) and a history of coffee drinking seems to improve your chances of recovery from a heart attack (myocardial infarction)(see KJ Mukamel, Am. Heart Journal vol. 157, p. 495, 2009). You can access abstracts of these articles by going to a website called and typing in the author name and year associated with the article.
