Virulence of Helicobacter pylori appears to be a key factor in the ulcer-causing bacteria's association with heart disease.
In a new study, Italian researchers have described 88 patients with ischemic heart disease and a control group of 88 patients matched by body mass index and socioeconomic levels. Almost two thirds, or 62%, of the people with heart disease also were infected with H pylori. However, the infection rate was 40% among people in the control group.
