Abstract
AIMS Cardiovascular outcomes of women with coronary artery disease (CAD) are perceived as relatively worse when compared to men. Amygdalar metabolic activity has recently been shown to independently predict cardiovascular events in patients without known cardiovascular disease. Given that traditional algorithms for risk prediction perform worse in women than in men, we sought to assess sex-specific associations between amygdalar metabolic activity and cardiac dysfunction with suspected or known CAD. METHODS AND RESULTS This retrospective study included 302 patients (mean age 66.8 ± 10.2 years, 29.1% women) selected for evaluation of CAD, malignant, or inflammatory disease. All patients had undergone both, myocardial perfusion imaging by single photon emission computed tomography (MPI-SPECT) and whole-body fluoro-18-deoxyglucose (18F-FDG) positron emission tomography (PET), within 6 months. 18F-FDG resting amygdalar uptake was significantly increased in women with abnormal MPI scans (standardized uptake value 33.4 ± 6.5 vs. 30.4 ± 4.7, P = 0.043), while no such difference was observed in men (P = 0.808). In women, but not in men, a negative association between 18F-FDG resting amygdalar activity and left ventricular ejection fraction (LVEF) was observed (Pearson r = -0.308, P = 0.004). Accordingly, either LVEF [B-coefficient (standard error, SE) = -0.232 (0.109), P = 0.045] or abnormal MPI [B-coefficient (SE) = 8.264 (2.449), P = 0.003] were selected as significant predictors of high amygdalar 18F-FDG uptake in a fully adjusted linear regression model in women, and a first order interaction term consisting of sex and LVEF or sex and abnormal MPI was significant (P = 0.035 and P = 0.001, respectively). CONCLUSION Resting amygdalar metabolic activity is associated with abnormal cardiac function and perfusion in women, suggesting a link between emotional stress and cardiovascular disease in women.

Abstract
BACKGROUND Inflammation plays a fundamental role in mediating all stages of atherosclerosis. Given the higher prevalence of inflammatory rheumatologic conditions in women and the female propensity towards worse cardiovascular outcomes, refined strategies are needed to better identify the high-risk female cardiovascular phenotype. OBJECTIVES This article aims to assess sex-specific links between inflammatory processes and the development and progression of ischemic heart disease. PATIENTS AND METHODS The relationship between vertebral bone marrow metabolism-a marker of inflammation-and myocardial injury was retrospectively assessed in 294 patients (28.6% women, mean age: 66.9 ± 10.0 years) who underwent 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) and 99mTc-tetrofosmin single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI). RESULTS A significant increase in 18F-FDG bone marrow uptake was observed in women with impaired myocardial perfusion (SPECT-MPI) as compared to women with normal myocardial perfusion (standardized uptake value [SUV]: 2.2 ± 1.2 vs. 1.7 ± 0.5, p = 0.013), while no such difference was observed in men (SUV: 1.6 ± 0.8 vs. 1.6 ± 0.4, p = 0.372). Furthermore, a significant inverse correlation between left ventricular ejection fraction (LVEF) and bone marrow metabolism was seen in women (r = -0.229, p = 0.037), but not in men (r = -0.075, p = 0.289). Accordingly, in women, but not in men, bone marrow activity was identified as an independent predictor of both, reduced LVEF (β-coefficient, -4.537; p = 0.040) and impaired myocardial perfusion (β-coefficient, 0.138; p = 0.014). CONCLUSION A strong link between bone marrow metabolism and impaired myocardial function and perfusion was observed in women, but not in men. Our data suggest that novel biomarkers of inflammation might help to identify women at risk for ischemic cardiomyopathy and to tailor disease management to the female cardiovascular phenotype.
