Rosenberg et al. (1980) conducted a case-control in Myocardial infarction (n=1,590). Cigarette smoking vs. Never smoked was evaluated on Myocardial infarction (RR 6.9, p=<0.001). Cigarette smoking significantly increased the risk of myocardial infarction in women aged 30 to 49, with an estimated relative risk of 6.9 for those smoking 35 or more cigarettes per day.
