The recognition of sex differences in cardiovascular disease, particularly the manifestations of coronary artery disease (CAD) in post-menopausal women, has introduced new challenges in not only understanding disease mechanisms but also identifying appropriate clinical means of assessing the efficacy of management strategies. For example, the majority of treatment algorithms for CAD are derived from the study of males, focus on epicardial stenoses, and inadequately account for the small intramyocardial vessel disease in women. However, newer investigational modalities, including stress perfusion cardiac magnetic resonance imaging and positron emission tomography are providing enhanced diagnostic accuracy and prognostication for women with microvascular disease. Moreover, these investigations may soon be complemented by simpler screening tools such as retinal vasculature imaging, as well as novel biomarkers (e.g. heat shock protein 27). Hence, it is vital that robust, sex-specific cardiovascular imaging modalities and biomarkers continue to be developed and are incorporated into practice guidelines that are used to manage women with CAD, as well as gauge the efficacy of any new treatment modalities. This review provides an overview of some of the sex differences in CAD and highlights emerging advances in the investigation of CAD in post-menopausal women.

It is not known in detail whether postprandial lipaemia is associated with coronary artery disease (CAD) in women. To investigate this, we administered an oral vitamin A/squalene/fat meal to 24 post-menopausal women with angiographically proven CAD who were not taking hormone replacement therapy, and to 30 healthy controls (18 without and 12 with hormone replacement therapy) to evaluate the effects of CAD on postprandial lipoprotein metabolism. This was done by assessing squalene, triacylglycerols, retinyl palmitate and apolipoprotein B-48 (apoB-48) during the subsequent 24 h. The subjects with CAD had significantly higher fasting concentrations of squalene and apoB-48 in triacylglycerol-rich lipoproteins (TGRL) compared with the controls. The postprandial areas under the incremental curve of TGRL apoB-48, chylomicrons, very-low-density lipoprotein (VLDL) and TGRL squalene, and of retinyl palmitate in VLDL only, were significantly higher in women with CAD than in controls. Adjustment for fasting values did not eliminate the differences in postprandial squalene and apoB-48 between CAD and controls. The postprandial responses of control subjects were not influenced by hormone replacement therapy. The peaks of squalene and retinyl palmitate of the controls, but not of the women with CAD, occurred significantly earlier (P < 0.01 for both) in chylomicrons than in VLDL. The findings suggest that lipoproteins that accumulate postprandially are labelled by dietary squalene, and that these lipoproteins may be atherogenic in post-menopausal women.

We studied a population of post-menopausal women with persistent chest pain (PChP) in order to investigate the relationship between myocardial perfusion at rest and during a stress test using magnetic resonance imaging (MRI). Our goals were to document whether transient myocardial perfusion is induced by dipyridamole infusion and if perfusion defects are also present at rest. The study population consisted of 45 consecutive women (mean age 57.6±8.7 years), who reported chest pain symptoms. PChP was defined as self-reported continuing chest pain after one year. We compared the results of the perfusion MRI studies in subgroups with and without obstructive coronary artery disease (CAD). The latest tools and technologies of Synapse™ Cardiovascular – Fujifilm’s cardiovascular (CV) image and information management system – helped us to achieve clear and comprehensive outcomes. In the group of women with PChP and non-obstructive CAD, 16 of 34 (48%) showed a well-evident left ventricular perfusion defect at baseline (four in one segment; eight in two segments and four in three or more segments). The localisation of the perfusion defects – seen using Synapse Cardiovascular – were anteroapical (n=6); septal (n=10); and inferoor inferolateral (n=4). These defects were ‘permanent’ or ‘fixed’, i.e. were present at rest and were neither induced nor modified by the administration of dipyridamole. In any of the women with CAD we found these anomalies. ‘Fixed’ perfusion defects at MRI – probably due to permanent damage of the coronary microcirculation – suggest a disease state typical for post-menopausal women with PChP.
