Washington DC, Sept. 8 -- Scientists from Finland and the UK have uncovered groundbreaking evidence that heart attacks may be triggered by infectious processes rather than just cholesterol and lifestyle factors.

Hidden bacterial biofilms inside arterial plaques can remain dormant for decades, shielded from the immune system, until activated by a viral infection or another external trigger.

Once awakened, the bacteria spark inflammation, rupture arterial plaques, and cause blockages that lead to heart attacks.

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 o...
