摘要

Abdominal visceral adipose tissue (AVAT) is associated with the incidence of cardiovascular events (CVEs). We retrospectively evaluated the association between AVAT and the incidence of CVEs in 602 patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI). Patients were divided into four groups according to the quartiles of AVAT areas using computed tomography. The incidence of CVEs (cardiovascular death, ACS recurrence and stroke) during the follow-up period (median 49.5 months) was evaluated. Cox analysis adjusting for cardiovascular risk factors revealed that the AVAT quartile classification exhibited a significant association with the incidence of CVEs. The risk in quartile 3 (moderate AVAT areas, ≥ 106.0 to < 142.6 cm2) was significantly lower than in quartiles 1 (low AVAT areas, < 71.0cm2; P < 0.01; hazard ratio [HR], 5.06), 2 (mild AVAT areas, ≥ 71.0 to < 106.0 cm2; P < 0.01; HR, 4.25) and 4 (severe AVAT areas, ≥ 142.6 cm2; P < 0.01; HR, 4.52). Polynomial analyses revealed that quadratic model was the most appropriate to illustrate the relationship between AVAT area and the hazard ratios for CVEs (corrected Akaike's information criterion, 49.2; R2, 0.47). The AVAT area and the incidence of CVEs exhibited a U-shaped relationship in patients with ACS undergoing PCI independent of conventional cardiovascular risk factors. The risk of CVEs was the lowest in patients with moderate AVAT areas. Evaluating AVAT may provide additional information for the assessment of long-term prognosis in patients with ACS.
