ACUTE CORONARY SYNDROME WITHOUT HEMODYNAMICALLY SIGNIFICANT ATHEROSCLEROTIC STENOSIS OF THE CORONARY ARTERIES: POTENTIAL ROLE OF AUTONOMIC IMBALANCE AND THE STATE OF VASCULAR ENDOTHELIUM
The study examined a subgroup of patients who have failed to identify hemodynamically significant narrowing of the coronary arteries due to atherosclerotic process mainly causing the development of acute coronary insufficiency. It is found that these patients had significantly more pronounced abnormalities of endothelial function, considering the control group, than in the presence of coronary artery stenosis.
