Abstract Purpose Perivascular epicardial adipose tissue (PEAT) has been linked to underlying coronary artery disease (CAD) and proposed to modulate adjacent atherosclerotic plaque formation. In vitro and ex vivo studies support bilateral influence of adipose tissue and vessel wall. Therefore, we quantified PEAT volume and composition and its dynamics in a low coronary risk patient cohort with a semi-automate software in serial CT exams. Methods and materials We retrospectively included 120 patients (27% females) from a tertiary care hospital who underwent serial cardiac CT angiographies with a low cardiovascular risk profile. All coronary CTs were evaluated in a standardized approach: epicardial adipose tissue (EAT) volume and attenuation was quantified in total, in the atrioventricular (RCA, LCX) or interventricular (LAD) sulcus and in a 5mm radius for each coronary artery (PEAT). Coronary plaques were quantified using a semi-automated software and compared to progression, stability of regression between the two scans. The measurements were compared on a per-patient and per-vessel basis between plaque-naïve and diseased vessels. Results Of 120 patients (32% female), 59.2%) had atherosclerotic plaque formation. After 36 months mean follow-up, 22 (18.3%) showed a CAD regression plaques, 39 (32.5%) had stable coronary arteries and 49 (40.8%) progressive CAD. Total EAT volume decreased by −15.6±37.2 mm3 in the regressive group, increased by 2.7±30.6mm3 in the stable group and by 24.3±37.1mm3 in the progressive CAD group (p=0.003). Per-vessel analysis showed a significant decrease of perivascular EAT attenuation in patients with CAD regression (−3.8±7.6 HU) compared to CAD stable (1.2±9.1 HU) and CAD progressive patients (3.5±8.2 HU, p<0.0001). Mean sulcus EAT attenuation did not show a significant change at follow-up (p=0.135) Conclusion Epicardial adipose tissue volume is mutually changing with the progression or regression of coronary artery disease. Perivascular but not epicardial attenuation levels correlated to adjacent plaque and support a direct bilateral influence.

ABSTRACT Introduction: It is often believed that chest pain relieved by nitroglycerin is indicative of coronary artery disease origin. Objective: To determine if relief of chest pain with nitroglycerin can be used as a diagnostic test to help differentiate cardiac chest pain and non-cardiac chest pain. Design: Prospective observational cohort study with a 4-week follow-up of patients enrolled. Setting: Academic tertiary care hospital, with 60 000 visits/year. Inclusion criteria: Adult patients presenting to the emergency department with active chest pain who received nitroglycerin and were admitted for chest pain. Exclusion criteria: Patients with acute myocardial infarction diagnosed after obtaining an ECG, patients whose chest pain could not be quantified, those for whom no cardiac work-up was done, or those who received emergent cardiac catheterization. Results: 270 patients were enrolled. Nitroglycerin relieved chest pain in 66% of the subjects. The diagnostic sensitivity of nitroglycerin to determine cardiac chest pain was 72% (64%–80%), and the specificity was 37% (34%–41%). The positive likelihood ratio for having coronary artery disease if nitroglycerin relieved chest pain was 1.1 (0.96–1.34). Telephone follow-up at 4 weeks was performed, with a 95% follow-up rate. Conclusions: Relief of chest pain with nitroglycerin is not a reliable diagnostic test and does not distinguish between cardiac and non-cardiac chest pain.
