ABSTRACT
SUMMARY OBJECTIVE With the adoption of optical coherence tomography (OCT), this study targets the impacts on plaque characteristics brought about by impaired glucose tolerance (IGT) in patients with coronary artery disease. METHODS For this study, 150 patients with coronary artery disease were recruited. Regarding glycosylated hemoglobin (HbAlc), the patients were sectioned into normal glucose tolerance (NGT), impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and diabetes mellitus (DM) groups. Coronary angiography (CAG) and OCT were conducted for 150 patients. RESULTS There were 186 plaques discovered in 150 patients (37, 40, 44, and 65 in the NGT, IFG, IGT, and DM groups, respectively). Compared to the NGT group, the lipid core size, which is presented as the average angle of the lipid arc, was markedly larger in the IFG,IGT and DM groups ( 135.7 ± 32.7 Ê, 161.2 ± 55.7 Ê, 162.5 ± 55.8 Ê, and 170.2 ± 59.7 Ê, respectively, all P values< 0.05). Meanwhile, the fibrous cap over the lipid core in the NGT group was remarkably thicker than that in the IFG, IGT, and DM groups (115.7 ± 47.7 μm vs. 77.7 ± 23.5 μm, 75.1 ± 23.2 µm, 71.2 ± 22.1 µm, all P values<0.05). CONCLUSION Coronary plaques in coronary artery patients with NDT are more stable than in those with IGT and DM.
RESUMO
RESUMO OBJETIVO Com a adoção da tomografia de coerência óptica (OCT), o presente estudo visa as características dos impactos na placa trazidos pela tolerância diminuída à glicose (IGT) em pacientes com doença na artéria coronária. MÉTODOS Cento e cinquenta doentes com doença arterial coronária foram recrutados para este estudo. De acordo com a hemoglobina glicosilada (HbAlc), os pacientes foram divididos em grupos tolerância normal à glicose (NGT), diminuição da glicemia de jejum (IFG), diminuição da tolerância à glicose (IGT) e diabetes mellitus (DM). Angiografia coronária (CAG) e OCT foram conduzidas para 150 doentes. RESULTADOS Existem 186 placas descobertas em 150 doentes (37, 40, 44 e 65 nos grupos NGT, IFG, IGT e DM, respectivamente). Em relação ao grupo NGT, o tamanho do núcleo lipídico, que é apresentado como o ângulo médio do arco lipídico, foi significativamente maior nos grupos IFG, IGT e DM (135,7 ± 32,7 Ê, 161,2 ± 55,7 Ê, 162,5 ± 55,8 Ê, e 170,2 ± 59,7 Ê, separadamente, os valores de P<0,05). Entretanto, a tampa sobre o núcleo de lipídios fibrosos no grupo NGT estava bem mais grossa do que nos grupos IFG, IGT e DM (115,7 ± 47,7μm vs. 77,7 ± 23,5 μm, 75,1 ± 23,2 µm, 71,2 ± 22,1 µm, todos os valores de P<0,05). CONCLUSÃO Placas coronárias na artéria coronária de pacientes com NDT são mais estáveis do que em doentes com IGT e DM.
