dc.description.abstract Background The 5-year follow-up results for the 1202 middle-aged men prospective study of CHD incidence were published in 1980. This paper extends the follow-up, relating the development of CHD to ten risk factors. Methods The population studied comprised all men born in aged 45-64 years at baseline who were registered in six group practices in Belfast. Some 1202 CHD-free men entered the study. Study endpoints included: (a) the development of CHD, (b) of myocardial infarction, (c) of angina pectoris (d) death from myocardial (d) death from other causes. The men were followed for an average of 6.9 years and the influence of ten risk factors was assessed by Cox’s proportional hazards model in a competing risk framework. Results The analysis first major CHD event identified 4 risk factors – diastolic blood pressure, serum cholesterol, T wave abnormality and tobacco index. First myocardial depended on diastolic blood pressure, ST abnormality and tobacco index, while time to first angina pectoris depended on serum cholesterol, T abnormality, tobacco index and age at entry. These findings do not support the hypothesis of a common risk factor profile in the myocardial infarction and angina pectoris groups. The sensitivity of all models was poor. Discussion The study confirms the role of known risk factors in the development of first CHD event. It also suggests that the risk factors involved in developing myocardial infarction and angina pectoris differ. The poor sensitivity of models suggests the presence of unmeasured risk factors in the aetiology of CHD. en_US
