Oral Pathogen Linked to Increased Heart Attack Damage: Scientists Uncover Hidden Peril
A study from Tokyo Medical and Dental University reveals that the oral pathogen Porphyromonas gingivalis, which causes gum disease, can hinder the self-repair of cardiac myocytes after a heart attack. The bacterium disrupts the fusion of autophagosomes and lysosomes, leading to impaired heart tissue restructuring and an increased risk of heart rupture. Treating oral infections may help prevent fatal heart attacks.
