An update on the role and mechanisms of periodontitis in cardiovascular diseases.

Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Despite extensive studies into the causes and therapies for CVDs, their incidence and prevalence continue to increase. Periodontitis is a multifactorial, chronic inflammatory disease related to systemic health. Current research suggests that periodontitis may be an unconventional risk factor for CVDs and it may increase the risk of CVDs such as atherosclerosis, coronary heart disease, myocardial infarction, hypertension, heart failure as well as cardiomyopathy. For all these reasons, it is quite plausible that prevention of periodontitis has an impact on the onset or progression of CVDs. Therefore, in this review, we investigated the association between periodontitis caused by oral microorganisms and different CVDs. In addition, we discuss the various mechanisms by which periodontitis contributes to the onset and progression of CVDs. Our review aims to raise global awareness of periodontitis, particularly its role in CVDs, provide a basis for the prevention and treatment of CVDs and offer potential therapeutic targets.
