The risk of myocardial infarction among Finnish farmers seeking medical care for an infection

Am J Public Health. 1996 Oct;86(10):1440-2. doi: 10.2105/ajph.86.10.1440.


Objectives: This study determined whether people visiting a doctor because of infection had an increased risk of myocardial infarction.

Methods: For 83 case patients and 249 matched control patients nested in a cohort of 3172 Finnish male farmers, comparisons were made on the basis of visits to a doctor because of infection.

Results: Infections of the upper respiratory tract were statistically significantly associated with coronary artery disease. The odds ratio was 3.2 (95% confidence interval = 1.2, 8.5) for patients visiting a doctor four or more times because of infection of upper respiratory tract compared with patients with three or fewer visits.

Conclusion: Men in this sample with recurrent or chronic infections of the upper respiratory tract exhibited a pronounced risk for myocardial infarction.
