Mouth bacteria ncrease heart attacks risks

Washington, April 1 (IANS) Scientists have found that more bacteria in the mouth greatly increase the risk of heart attacks.
The two main pathogens, Tannerella Forsynthesis and Preventella Intermedia, have a statistically significant association with greater vulnerability to heart attack.

The study, conducted by University of Buffalo (U-B), involved 386 men and women between the ages of 35 and 69 who had suffered a heart attack and 840 people free of heart trouble, who served as controls.

Samples of dental plaque were collected from 12 sites in the gums of all participants. The samples were analysed for the presence of the six common types of periodontal bacteria, as well as the total number of bacteria.

The patients harboured more of each type of bacteria than the controls, the analysis showed.

An increase in the number of different oral bacteria also increased the odds of having a heart attack, results showed.

Prospective studies - those that measure oral bacteria in participants who have had no heart problems when they enter the study, and again when a heart attack occurs in a participant - are needed to better assess this potential association, noted Oelisoa M. Andriankaja, post-doctoral researcher at the University at Buffalo School of Dental Medicine.

The study was funded by the National Institute of Dental and Craniofacial Research, said a university release.

These results will be presented during the international Association of Dental Research General Session being held in Miami April 1-4.
