摘要：Background: Adiponectin is associated with many cardiovascular risk factors. Thus, a relation between adiponectin and subsequent coronary heart disease has been hypothesized. However, the results of prospective studies have been conflicting. Methods: In this nested case-control study, blood samples were collected from 5243 of 12 490 community residents enrolled in the Jichi Medical School Cohort Study. The samples were taken between 1992 and 1995 and stored until 2007, at which point the plasma adiponectin level was measured. Results: During an average of 9.4 years of follow-up, 38 patients with myocardial infarction and 89 controls matched for age, sex, and community were identified. Plasma adiponectin concentration did not significantly differ between cases and controls (geometric mean 7.6 [interquartile range, 5.0–12.2] versus 7.4 [5.4–11.0] mg/L, respectively, P = 0.57). The odds of myocardial infarction in the lowest tertile of adiponectin concentration was not significantly different from that in the highest tertile, after adjustment for age and sex (OR 1.33; 95% CI, 0.50–3.55) or after further adjustment for other cardiovascular risk factors (OR 1.68; 95% CI, 0.45–6.25). Similarly, there was no significant difference in odds of myocardial infarction between the lowest and highest quartiles of adiponectin concentration. Conclusion: The results do not support an association between hypoadiponectinemia and myocardial infarction.
