Periodontal Diseases and Heart Diseases: A Systemic Review.

Introduction: 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. Materials and Methods: 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. Results: 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). Conclusion: 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.
