Each year there are 800,000 myocardial infarctions in the United States. There is an increased risk of hospitalization for acute myocardial infarction (AMI) for those with periodontal disease.

The authors’ aim was to examine the association between periodontal care and AMI hospitalization and 30 days after acute care.
