Myocardial infarction may be an infectious disease (tuni.fi)

Article summary

Researchers from Tampere University and other institutions have found that an infection may trigger myocardial infarction, with bacteria forming a biofilm in atherosclerotic plaques that can lead to inflammation and rupture of the plaque. The study suggests that bacterial involvement in coronary artery disease has long been suspected, but direct evidence was lacking. The findings may pave the way for novel diagnostic and therapeutic strategies for myocardial infarction. The research was conducted using tissue samples from individuals who had died from sudden cardiac death and patients with atherosclerosis.

What commenters say

• The title of the article is misleading, as the bacteria are not the sole cause of myocardial infarction, but rather a potential trigger.
• The study provides evidence that bacterial biofilms in atherosclerotic plaques can lead to inflammation and rupture, causing myocardial infarction.
• Not all myocardial infarctions are caused by infectious disease, and other factors such as congenital conditions or thickening of the heart tissue can also contribute.
• The relationship between HPV and cervical cancer is complex, and while HPV is a major cause, there may be other factors at play, including spontaneous mutations or other infections.
• The study's findings are significant, but more research is needed to fully understand the mechanisms behind myocardial infarction and to develop effective treatments.
• The flu can exacerbate existing cardiovascular conditions, leading to serious cardiac events, including heart attacks.
• The concept of 'infectious disease' is nuanced, and the presence of bacteria in atherosclerotic plaques does not necessarily imply a direct causal link to myocardial infarction.
• The study's use of a custom antibody to identify bacterial biofilms in atherosclerotic tissue provides strong evidence for the role of bacteria in myocardial infarction.
