Heart attacks may be linked to infections: study

Oral bacteria in artery plaques may trigger heart attacks by causing inflammation.

Why it matters

  • Heart attacks might be triggered by infections, not just cholesterol.
  • This discovery could lead to new treatments and prevention methods, like vaccines.

By the numbers

  • The study involved researchers from Finland and the UK.
  • Tissue samples were obtained from individuals who died from sudden cardiac death and patients with atherosclerosis.

The big picture

  • The study challenges the traditional view of heart attack causes.
  • It suggests that oral health might be more directly linked to heart health than previously thought.
  • New diagnostic and therapeutic strategies could be developed based on these findings.

What they're saying

  • "Bacterial involvement in coronary artery disease has long been suspected, but direct and convincing evidence has been lacking." - Professor Pekka Karhunen
  • The study suggests a potential link between oral health and heart attacks.

Caveats

  • The study does not provide information on sample size.
  • Further research is needed to confirm these findings and develop new treatments.

What’s next

  • The findings could lead to the development of vaccines or antibiotics to prevent or treat heart attacks caused by bacterial infections.
