Contribution of periodontal health in cardiovascular secondary prevention: Analyses on hospitalized patients in cardiology units

Aim To investigate the association between dental health and incident cardiovascular disease (CVD) in secondary prevention setting. Materials and Methods A total of 888 patients with known CVD hospitalized in the cardiology unit were prospectively enrolled. We assessed the association between missing teeth and three variables of periodontitis and major adverse cardiovascular events (MACE), defined as a composite of cardiac death, acute myocardial infarction, stroke and hospital re‐admission for congestive heart failure. Results During a median (Q1, Q3) follow‐up of 4.6 (1.4, 6.7) years, an additional missing tooth was associated with a 3% (95% confidence interval [CI]: 1%–5%) higher hazard of MACE (p = .004). Compared with patients with 0 to ≤4 missing teeth, periods free from MACE (95% CI) by 5 years of follow‐up were, on average, shorter by 0.17 (−0.04 to 0.37) years, 0.26 (0.04–0.49) years and 0.59 (0.34–0.85) years in patients with 5 to ≤7, 8 to ≤13 and >13 missing teeth, respectively. No significant associations were observed between periodontal measures and MACE incidence. Conclusions In hospitalized patients with existing CVD, the total number of missing teeth was associated with incident MACE.
