Background: Endothelial dysfunction is recognized as one of the early markers of cardiovascular disorders. It is supposed to be a potential predictor of cardiovascular complications in patients receiving adjuvant and neoadjuvant chemotherapy. Aim: To estimate the prevalence of endothelial dysfunction in solid cancer patients compared to that in individuals without any malignancies. Materials and methods: This observational study included 74 patients with solid malignancies, mostly gastrointestinal. Prior to polychemotherapy, all patients were examined for endothelial function of small and large arteries (AngioScan-01, Fiton, Russia) and peripheral artery stiffness (pulse wave contour analysis and occlusion test). The results were compared with those of the Russian population trials of endothelial dysfunction Meridian-RO (Ryazan region) and trial in the rural population of the Krasnodar region. Results: Compromised vasodilation and smaller arteries tone were found in 64.9% (48/74) of the cancer patients, while impaired vasodilation of larger muscular arteries was present in 94.6% (70/74) of the patients. According to the Meridian-RO trial in the Ryazan region, endothelial dysfunction had been found in 51.2% (n = 341) of women and 52.4% (n = 300) of men, whereas the Krasnodar regional population data had shown it in 68.4% (n = 353) of women and 71.7% (n = 253) of men. Conclusion: The prevalence of endothelial dysfunction in the patients with solid malignancies, who have not undergone any chemo- or radiation therapy, is significantly higher than in the population of comparable age, conventional cardiovascular risk factors, and comorbidities. No significant increase of vascular stiffness was identified.
