Myokardinfarkt kann eine infektiöse Erkrankung sein: Die Studie zeigte das Vorhandensein von DNA aus mehreren oralen Bakterien innerhalb atherosklerotischer Plaques. Das Immunsystem des Körpers reagierte auf diese Bakterien und löste eine Entzündung aus, die die cholesterinbeladene Plaque baute.

I’ve linked to the press release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:
**Myocardial infarction may be an infectious disease**
A pioneering study by researchers from Finland and the UK has demonstrated for the first time that myocardial infarction may be an infectious disease. This discovery challenges the conventional understanding of the pathogenesis of myocardial infarction and opens new avenues for treatment, diagnostics, and even vaccine development.
“Bacterial involvement in coronary artery disease has long been suspected, but direct and convincing evidence has been lacking. **Our study demonstrated the presence of genetic material – DNA – from several oral bacteria inside atherosclerotic plaques**,” Karhunen explains.
The findings were validated by developing an antibody targeted at the discovered bacteria, which unexpectedly revealed biofilm structures in arterial tissue. Bacteria released from the biofilm were observed in cases of myocardial infarction. **The body’s immune system had responded to these bacteria, triggering inflammation which ruptured the cholesterol-laden plaque**.
That’s a fascinating angle on heart disease. It suggests that oral health and infections might play a more direct role in triggering heart attacks than previously thought. If bacteria can invade plaques and spark inflammation, it could help explain why some people have heart attacks even without classic risk factors. It also underscores the importance of good oral hygiene as part of overall cardiovascular health.
So.. can you treat it with penicillin or antibiotics?
Makes total sense to me! Especially the Oral-Cardiac link.
For years, we have known about the link between bad oral health and potential cardiac issues. Now we have more evidence to support the correlation and causation! Dentists are enjoying this unfortunate vindication right now, haha
