AHA Committee Report. Risk factors and coronary disease. A statement for physicians.

Clinical, laboratory and epidemiological studies show that certain readily identifiable lifestyles and biological features characterize those persons who are at high risk to develop coronary heart disease (CHD). The first AHA document on this subject, dealing with primary prevention of the atherosclerotic diseases, was published in 1964. It was based in part on earlier AHA statements on smoking (1959) and diet (1961). This information is incorporated into the 1968 statement, "Risk Factors and Coronary Disease." New research information has been accumulated about risk factors in the intervening 12 years, and continues to show that no single risk factor is etiologic--multiple causal factors play interrelated roles in CHD.
