Inflammatory changes in small blood vessels in the endomyocardium of cardiac syndrome X in female patients with increased C-reactive protein.

Abstract

The pathogenesis and pathohistological changes of CSX, a syndrome characterized by anginal chest pain and normal coronary arteries on coronary angiography, is poorly understood. The purpose of this study was to analyse morphological changes in small blood vessels of the CSX patients with increased CRP levels (above 5 mg/l). EMB was performed for diagnostic purposes in 31 female patients with CSX, and EMB specimens were histologically and immunohistochemically analysed. Increased CRP was found in 18 (58.1%) female patients with CSX. Signs of inflammation in the walls of small blood vessels were demonstrated in 13 (76%) and TUNEL-positive endothelial cells in 3 (17%) women with increased CRP. Morphological analysis of small blood vessels in EMB in CSX female patients with increased CRP levels revealed signs of inflammation and apoptosis of endothelial cells, indicating the role of inflammation in the pathogenesis of CSX.
