This study aimed to investigate the association between periodontal disease severity, coronary calcifications, and unstable plaque features in patients with unstable angina. Patients with high periodontal index had larger plaque and noncalcified plaque volume. Vulnerability features in atheromatous plaques were significantly correlated with periodontal index. Gingival attachment loss and papillary bleeding index were strongly associated with high-risk plaques. Periodontal index correlated significantly with coronary calcium score, but not with traditional markers of subclinical atherosclerosis. Subgroup analysis showed that patients with advanced periodontal disease and unstable angina presented with a higher amount of coronary calcium and a more vulnerable plaque phenotype.
The present study aimed to investigate the link between the severity of periodontal disease (PD), coronary calcifications and unstable plaque features in patients who underwent coronary computed tomography for unstable angina (UA). Fifty-two patients with UA, included in the ATHERODENT trial (NCT03395041), underwent computed tomographic coronary angiography (CCTA) and dental examination. Based on the median value of the periodontal index (PI), patients were assigned to the low periodontal index (LPI) group (PI < 22) and a high periodontal index (HPI) group (PI > 22). Patients with HPI had higher plaque volume (p = 0.013) and noncalcified plaque volume (p = 0.0003) at CCTA. In addition, the presence of vulnerability features in the atheromatous plaques was significantly correlated with PI (p = 0.001). Among periodontal indices, loss of gingival attachment (p = 0.009) and papillary bleeding index (p = 0.002) were strongly associated with high-risk plaques. PI significantly correlated with coronary calcium score (r = 0.45, p = 0.0008), but not with traditional markers of subclinical atherosclerosis. Overall, this subgroup analysis of the ATHERODENT study indicates that patients with advanced PD and UA present a higher amount of calcium in the coronary tree and have a more vulnerable phenotype of their culprit plaques.
