Periodontal disease and coronary plaque vulnerability-Insights from the the ATHERODENT
Study

The role of periodontal disease (PD) as a mediator of systemic
inflammation has beenwell established. At the same time, PD
has been recognized to play a significant role in progression
of cardiovascular diseases, being associated with the severity
of coronary artery lesions. However, its association with high-
risk atheromatous plaque in the coronary arteries has not
been elucidated so far. The purpose of the ATHERODENT trial
(ClinicalTrials.gov Identifier: NCT03395041) was to evaluate
the interrelation between severity of periodontal disease (PD)
and coronary plaque vulnerability, in patients with unstable
angina.
Methods:
So far, 52 patients with unstable angina were
enrolled in the ATHERODENT clinical trial, who underwent:
(1) complex dental examination for assessment of periodontal
diseases as expressed by periodontal index (PI) and (2)
coronary computed tomography angiography for analysis of
morphology, composition and vulnerability features of the
culprit coronary plaques causing myocardial ischemia.
Results:
ThetotalPIwasdirectlycorrelatedwiththetotalamount
of calcium in the coronary arteries, as expressed by coronary
calcium score (r=0.45, p=0.0008). Coronary calcium score was
significantly higher in patients with hight PI (505.29±478.64
vs 93.82±233.0,p=0.0001). Similarly, patients with high PI
presented a significantly higher plaque volume in lesions causing
ischemia (p=0.019), and a larger volume of non-calcified plaque
(p=0.002). At the same time, we assessed several features of
high risk in coronary plaques such as positive remodeling, low
density atheroma, spotty calcification and napkin-ring sign.
Interestingly, patients with high risk atheormatous plaques
presented more severe PD as expressed by the loss of gingival
attachments (3.6±2.91 vs. 1.66±1.8, p=0.009), papillary bleeding
index (4.5±3.06vs. 2.04±1.96, p=0.002) and total PI (28.20±13.34
vs. 18.71±11.31, p=0.001) than those with low risk plaques.
Conclusions:
Presence of periodontal disease is associated
with a more vulnerable phenotype of the atheromatous
plaques causing an acute coronary event. Patients with
high-risk features of the culprit coronary plaques present an
increased severity of the PD as compared to patients with
low-risk atheromatous lesions. These indicate that PD could
represent a maker of increased risk in patients with coronary
artery disease.
