Periodontal Diseases and Heart Diseases: A Systemic Review.

Abstract

Up to 50% of people worldwide are affected by periodontal disease (PD); cardiovascular diseases are a serious concern for the major portion of the world's population. Observational data have shown a connection between PD and CVD. The current systemic review investigates the incidence of the CVD in individuals with PD through various designs of the previous research. An extensive online search in the various databanks of EMBASE, Medline, Pubmed, and Scopus was conducted. The keywords searched were: "PD, CVD, myocardial infarction, coronary heart disease (CHD), and stroke; technique of diagnosis and the degree of PD were assessed clinically or by self-report." The studies selected were longitudinal research design and randomized trials. To ascertain the risk of mortality due to cardiac issues in periodontal diseases, meta-analysis, and meta-regression were carried out. The diagnosis techniques for periodontal diseases, severity, and impact of gender, were also examined. After full-text screening, 32 longitudinal cohort studies were included. PD patients had a significantly greater risk of CVD than non-PD patients (RR: 1.20). Clinical and self-reported PD diagnoses did not differ in CVD risk (RR = 0.97). Men were at increased risk for both severe PD (RR: 1.25), and CVD (RR: 1.16). The risk of stroke was the highest among all forms of CVD (RR = 1.24), and the risk of CHD was significantly elevated (RR = 1.14). Current review showed that populations with PD consistently and modestly have an elevated risk of CVD. Men and those with severe PD are at higher CVD risk, which suggests population-targeted therapies may be helpful.
