Recent studies have demonstrated that smokers are more likely than nonsmokers to develop heart disease  Other studies have established that smokers are more likely than others to drink caffeinated beverages
Ttherefore, even though drinking caffeinated beverages is not thought to be a cause of heart disease, there is a positive correlation between drinking caffeinated beverages and the development of heart disease
it is only among people who have a hereditary predisposition to heart disease that caffeine consumption is positively correlated with the development of heart disease
