A study recently reported in the journal Circulation found that taking antibiotics is not an effective form of therapy for coronary heart disease, disputing two earlier studies from Argentina and England. The Utah study was conducted with 302 participants who were infected with C. pneumonia. Of those, 150 were given the antibiotic azithromycim. Researchers reported the following three possible findings: C. pneumonia does not cause coronary artery disease; azithromycin produces only a small benefit; or C. pneumonia causes coronary artery disease but the wrong antibiotic was used.
