Background There is evidence that atherosclerosis begins in childhood. There is also evidence that inflammatory markers measured in middle and old age predict risks of cardiovascular disease. In this report, we test whether an inflammatory marker measured in young adult men is associated with risk of myocardial infarction in middle age. Methods During Swedish national conscription tests from 1969 through 1978, the erythrocyte sedimentation rate, as a measure of inflammation, was measured in 433,577 young Swedish men. The cohort was observed for subsequent myocardial infarction events through December 2009. Results During an average follow-up time of 35 years, a total of 8,081 first-time myocardial infarctions occurred within the cohort. After adjustments for potential confounders and known risk factors for myocardial infarction, men with an elevated erythrocyte sedimentation rate (>= 15 mm/h) had a 1.7 times increased risk of myocardial infarction during follow-up (95% CI 1.4-2.1) compared with men with an erythrocyte sedimentation rate of 1 mm/h. This relationship was dose dependent for each unit increase in erythrocyte sedimentation rate (P for trend < .001). Conclusions In this cohort of young Swedish men, the erythrocyte sedimentation rate was associated with risk of myocardial infarction 35 years later after control of the available data on other coronary risk factors. These data add important relevant information to the existing evidence that atherosclerosis begins in childhood.
