Abstract

Aim To evaluate dynamics of biomarkers for endothelial dysfunction (ED), including endothelin-1 (ET-1) and von Willebrand factor (VWF) in patients with stomach cancer (adenocarcinoma) before and after polychemotherapy (PCT); to compare these results with respective values in healthy volunteers and patients with cardiovascular diseases (CVD); to study correlations of the ED biomarkers with indexes of instrumental evaluation of endothelial dysfunction.Material and methods The study included 75 participants, including 25 healthy volunteers (control group), 25 patients with documented CVDs (arterial hypertension + ischemic heart disease), and 25 patients of the main group with histologically documented stage II-IV stomach cancer (adenocarcinoma) who received different courses of PCT with platinum-based agents (oxaliplatin, cisplatin) and fluoropyrimidines (5 fluorouracil, capecitabin). Laboratory measurement of ED biomarkers, computerized nailfold video capillaroscopy (CNVC), and finger laser photoplethysmography (PPG) (methods for noninvasive evaluation of vascular wall and ED), electrocardiography, 24-h ECG Holter monitoring, and echocardiography (EchoCG) were performed for all patients of the main group prior to PCT and within o...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
