Abstract/OtherAbstract:
BACKGROUND: Metabolic syndrome (MetS) is associated with adverse cardiovascular events and mortality, where acute coronary syndrome significantly impacts on mortality and morbidity. In contrast, evidences have accumulated that the lipid-rich plaque might play a critical role in acute coronary syndrome.
METHODS AND RESULTS: The study population consisted of 94 patients with suspected angina pectoris who underwent multi-detector computed tomography (MDCT). Of those, we identified 41 with MetS. In MDCT analysis, low-density plaque volume (LDPV) (42 ± 28 vs 24 ± 18 mm(3), P=0.0003), moderate-density plaque volume (105 ± 41 vs 82 ± 33 mm(3), P=0.003), total plaque volume (164 ± 70 vs 118 ± 59 mm(3), P=0.0008) and %LDPV (24.2 ± 10.0 vs 18.3 ± 7.1%, P=0.01) were significantly increased in the MetS group compared to the non-MetS group. Multivariate linear regression analysis after adjusting for confounding variables revealed that MetS was significantly correlated with an increase in %LDPV (β=0.48, P=0.0001). Multivariate logistic regression analysis for lipid-rich plaque after adjusting for confounding variables indicated that MetS was significantly associated with lipid-rich plaque (odds ratio: 5.99, 95% confidence intervals: 1.94-18.6, P=0.002).
CONCLUSIONS: Patients with MetS were strongly related to having a lipid-rich composition in their coronary plaque, as detected by MDCT.
