Functional performance status and risk of cardiovascular events and mortality following endovascular repair of thoracic and abdominal aortic pathology.

OBJECTIVE: To characterize the association of preoperative functional performance status based on Eastern Cooperative Oncology Group (ECOG) scoring with the risk of adverse cardiovascular events, vascular events, and mortality in patients undergoing EVAR and TEVAR. METHODS: Retrospective review of the Society for Vascular Surgery Vascular Quality Initiative, a large, multi-center, registry database was performed. All individuals undergoing EVAR (n = 18,730) and TEVAR (n = 6595) for non-ruptured aortic pathologies between 2014 and 2018 were eligible for analysis. Multivariable logistic regression was used to determine the association of pre-procedure ECOG functional performance status on risk of in-hospital adverse cardiovascular events, vascular events, and mortality. RESULTS: The number of operations complicated by adverse cardiovascular and vascular events was 480 (2.6%) and 190 (1.0%) for EVAR and 733 (11.1%) and 219 (3.3%) for TEVAR, respectively. There were 118 (0.6%) and 240 (3.6%) in-hospital deaths following EVAR and TEVAR, respectively. Patients with ECOG grades 3 or 4 undergoing EVAR were at increased risk of cardiovascular events (OR = 1.62; 95% CI = 1.09, 2.41) and one-year mortality (HR = 2.62; 95% CI = 1.92, 3.57) compared to those with ECOG grade 0. Patients undergoing TEVAR with ECOG grade 3 or 4 were at increased risk for both inpatient death (OR = 2.77; 95% CI = 1.56, 4.9) and one-year mortality (HR = 3.27, 95% CI = 2.06, 5.21). ECOG status was not associated with an increased risk of adverse vascular events following either EVAR or TEVAR. CONCLUSIONS: Poor preoperative functional status as assessed by ECOG score is associated with an increased risk of adverse postoperative cardiovascular events following EVAR and a higher mortality risk following both EVAR and TEVAR. Functional status assessment may be useful for risk stratification and determining procedural candidacy prior to EVAR and TEVAR.

Epicardial adipose tissue volume as a marker of coronary artery disease severity in patients with diabetes independent of coronary artery calcium: findings from the CTRAD study.

AIMS: The association between epicardial adipose tissue (EAT) volume and coronary artery disease (CAD) severity was evaluated, independent of traditional risk factors and coronary artery calcium (CAC) scores, in patients with diabetes type 2 (DM-2) using cardiac computed tomography angiography (CTA). METHODS: A multivariate analysis was utilized to assess for an independent association after calculating EAT volume, CAD severity, and calcium scores in 92 patients with DM-II from the CTRAD study. We graded CAD severity as none (normal coronaries), mild-moderate (<70% stenosis), and severe (70% or greater stenosis). RESULTS: A total of 39 (42.3%) asymptomatic patients with diabetes did not have CAD; 30.4% had mild/moderate CAD; and 27.1% had severe CAD. Mean EAT volume was highest in patients with severe CAD (143.14 cm(3)) as compared to mild/moderate CAD (112.7 cm(3)), and no CAD (107.5 cm(3)) (p = 0.003). After adjustment of clinical risk factors, notably, CAC score, multivariate regression analysis showed EAT volume was an independent predictor of CAD severity in this sample (odds ratio 11.2, 95% confidence interval 1.7-73.8, p = 0.01). CONCLUSIONS: Increasing EAT volume in asymptomatic patients with DM-II is associated with presence of severe CAD, independent of BMI and CAC, as well as traditional risk factors.

Comparison of epicardial adipose tissue volume and coronary artery disease severity in asymptomatic adults with versus without diabetes mellitus.

Epicardial adipose tissue (EAT) has been shown to have important effects on the development of coronary artery disease (CAD) through local paracrine influences on the vascular bed. We compared a cohort of asymptomatic patients with type II diabetes mellitus (DM) without known CAD to an age- and gender-matched group of asymptomatic patients without DM from the CTRAD (Cardiac CT's Role in Asymptomatic Patients with DM-II) study in which patients underwent a cardiac computed tomography angiogram, for early detection of CAD. Mean EAT volumes of 118.6 ± 43.0 and 70.0 ± 44.0 cm(3) were found in the DM and non-DM groups, respectively. When stratified by the presence and severity of CAD, it was found that in the DM (p = 0.003) and non-DM groups (p <0.001), there was a statistically significant increase in EAT volume as the patients were found to have increasingly severe CAD. After adjusting for age, race, gender, DM, hypertension, insulin use, body mass index, and coronary artery calcium (CAC) score, the presence of >120 cm(3) of EAT was found to be highly correlated with the presence of significant CAD (adjusted odds ratio 4.47, 95% confidence interval 1.35 to 14.82). We found that not only is EAT volume an independent predictor of CAD but that an increasing volume of EAT predicted increasing severity of CAD even after adjustment for CAC score.
