Low Yield Cigarettes and the Risk of Nonfatal Myocardial Infarction in Women

Abstract
Newer brands of cigarettes with reduced yields of nicotine and carbon monoxide have been promoted as being less hazardous than others. We evaluated the effect of smoking "low yield" cigarettes on the risk of nonfatal myocardial infarction in women under 65 years of age. The data were obtained in a case-control study of 910 women with a first myocardial infarction and 2375 hospital controls.
