To characterize microvascular function, candidate risk pathways, and metabolic syndrome prevalence in women with cardiac syndrome X, 52 nondiabetic women with angiographically normal epicardial arteries but >1 mm of planar ST depression during exercise testing (patients) and 24 healthy controls of similar age were recruited. In addition to fasting blood samples and anthropometric measurements, forearm cutaneous microvascular function after iontophoresis of acetylcholine and sodium nitroprusside was assessed by laser Doppler imaging. Despite body mass index correction and a larger proportion on statin therapy, patients had high levels of insulin (p=0.016), triglycerides (p=0.018), intercellular adhesion molecule-1 (p=0.021), von Willebrand factor (p=0.005), and leptin (p=0.005) and lower levels of high-density lipoprotein cholesterol (p=0.042) compared with controls. Consistent with these data, 30% of patients but only 8% of controls fulfilled criteria for the metabolic syndrome as defined by the National Cholesterol Education Program (p=0.015). Endothelium-dependent and -independent microvascular functions were markedly impaired in patients (p
