title: The important role of fitness determination and stress testing in predicting coronary incidence.
abstract: The question of whether there is some effect of status of cardiorespiratory fitness and exercise ECG abnormalities on occurrence of CHD other than their effect on the risk factors of serum cholesterol, blood pressure, glucose, and smoking seems to have been answered in the affirmative by this study. The relative prognostic importance of the measures considered here, the role of exercise, and the interrelationships between fitness, exercise, other risk factors, and CHD provide many interesting hypotheses for continued study. A future investigation will involve a large prospective study in which the risk function to be derived would include stress ECG and treadmill performance as predictor variables. The retrospective approach reported in this paper had certain limitations. It did, however, permit demonstration of new results because, essentially for the first time, all of the important risk factors are measured in the study population and can be evaluated simultaneously.
