All cases of initial myocardial infarctions (MI) diagnosed among men below age 40 in Göteborg during 1970-1977 have been studied. The cases have been compared with a random sample from the general population in Göteborg with respect to socio-economic factors and conventional risk factors. The MI-cases showed a special socio-economic pattern prior to the infarction and were more often single and of foreign origin, had more previous sickness benefit days and were more often registered for alcohol abuse than contemporaries in the general population. Moreover, the surviving MI-cases were found to be heavily burdened with the conventional risk factors smoking, cholesterolemia and high blood pressure.
对1970 - 1977年期间在哥德堡40岁以下男性中诊断出的所有初发心肌梗死（MI）病例进行了研究。就社会经济因素和传统风险因素而言，已将这些病例与哥德堡普通人群的随机样本进行了比较。心肌梗死病例在梗死前呈现出一种特殊的社会经济模式，他们更常为单身且来自外国，有更多既往疾病津贴天数，并且比普通人群中的同龄人更常被登记为酗酒。此外，发现存活的心肌梗死病例承受着吸烟、胆固醇血症和高血压等传统风险因素的沉重负担。
