Myocardial infarction
A number of acute and chronic infections including "Chlamydophila pneumoniae", influenza, "Helicobacter pylori", and "Porphyromonas gingivalis" among others have been linked to atherosclerosis and myocardial infarction. As of 2013, there is no evidence of benefit from antibiotics or vaccination, however, calling the association into question. Myocardial infarction can also occur as a late consequence of Kawasaki disease.
