title: Dental infection and the risk of new coronary events: prospective study of patients with documented coronary artery disease.
abstract: Several recent studies have suggested that dental infections are associated with coronary artery disease. To further elucidate this association, we conducted a prospective 7-year follow-up study of 214 individuals (182 males and 32 females; mean age, 49 years) with proven coronary artery disease who had undergone a dental examination and evaluation for the classic coronary risk factors at entry. The main outcome measures were the incidence of fatal and nonfatal coronary events and overall mortality. Fifty-two patients met the endpoint criteria during follow-up. Dental health was a significant predictor of coronary events when controlled for the following factors: age, sex, socioeconomic status, smoking, hypertension, the number of previous myocardial infarctions, diabetes, body mass index, and serum lipids. Other significant predictors were the presence of diabetes, the number of previous myocardial infarctions, and the body mass index. Our results give further support to the hypothesis that dental infections are a risk factor for coronary events.
