陳柏堅醫師之口腔細菌多 罹患心臟病機率高

（路透華盛頓1日電）
美國研究人員今天報告說，口腔裡面細菌最多的人，最可能罹患心臟病。研究人員表示，他們比較心臟病患與身體健康的志願者，發現心臟病患口中細菌數量比較高。

越來越多證據顯示，口腔衛生與整體健康有關聯

紐約州立大學水牛城分校（University at Buffalo）學者安德利安卡雅（Oelisoa Andriankaja）及同僚試圖找出，是否有某種特定的細菌可能導致心臟病。他們檢驗386名心臟病患及840名健康人士，顯示心臟病患口腔常見Tannerella forsynthesis及Prevotellaintermedia 兩種細菌。他們在國際牙醫學研究學會（International Association of Dental Research）邁阿密會議上指出，更驚人的是，口腔內存在最多種細菌的人，最可能罹患心臟病。

醫界不確定細菌如何導致心臟病，但是多項研究已經顯示，牙齦疾病與心臟病有關連。細菌可能引發全身發炎，接著導致發生血栓。

Germy mouths linked to heart attacks, study finds

WASHINGTON (Reuters) - People with the germiest mouths are the most likely to have heart attacks, U.S. researchers reported on Wednesday.

A study that compared heart attack victims to healthy volunteers found the heart patients had higher numbers of bacteria in their mouths, the researchers said.

Their findings add to a growing body of evidence linking oral hygiene with overall health.

Oelisoa Andriankaja and colleagues at the University at Buffalo in New York were trying to find if any particular species of bacteria might be causing heart attacks.

Their tests on 386 men and women who had suffered heart attacks and 840 people free of heart trouble showed two types -- Tannerella forsynthesis and Prevotella intermedia -- were more common among the heart attack patients.

But more striking, the people who had the most bacteria of all types in their mouths were the most likely to have had heart attacks, they told a meeting of the International Association of Dental Research in Miami.

"The message here is that even though some specific periodontal pathogens have been found to be associated with an increased risk of coronary heart disease, the total bacterial pathogenic burden is more important than the type of bacteria," Andriankaja, now at the University of Puerto Rico, said in a statement.

"In other words, the total number of 'bugs' is more important than one single organism."

Doctors are not sure how bacteria may be linked with heart attacks but several studies have shown associations between gum disease and heart disease. Bacteria may set off general inflammation that in turn causes blood to clot.
