Early research links a gum disease bacterium to heart valve calcification

Preliminary research at an American Heart Association meeting examined valve tissue from valve-replacement patients and found the gum disease bacterium Porphyromonas gingivalis among the biggest differences in calcified aortic valves; in mice, repeated exposure caused valve calcification. It is not yet peer-reviewed and shows an association, not proof of cause; a human study is under way.
