Abstract

Objective. Studies in 13 countries have revealed an association between malignant neoplasms (ZN) and an increased risk of cardiovascular diseases (CVD). Assessment of the effect of different localization of malignant neoplasm on the course of coronary heart disease, treatment tactics and outcomes.

Material and methods. 136 patients with coronary artery disease and coronary artery disease who underwent myocardial revascularization were examined. The study identified groups of patients with coronary heart disease and malignant tumors of various localization: gastrointestinal tract (GIT), respiratory organs (RO), endocrine organs (EO) and urinary system (US). The clinical parameters, medical history, the nature of coronary artery damage, methods and complications of myocardial revascularization, as well as the treatment features of oncopathology were analyzed.

Results. Patients with EO were older (73.6 years old), with a high incidence of obesity, hyperlipidemia, and aggravated heredity. Smoking, hypertension, and physical inactivity were common in all groups. The function of the left ventricle was normal, but patients with gastrointestinal tumors had a slightly decreased LVEF. In terms of coronary artery damage, a significant difference was observed in the lesion of the envelope branch of the LCA – it was much less common in MVS tumors. The choice of the revascularization method depended on the location of the tumor: PCI and CABG were used approximately equally for gastrointestinal tumors, and PCI was mainly performed for tumors of the endocrine organs and US. The incidence of complications after myocardial revascularization was highest in patients with gastrointestinal (22.5%) and RO (19.8%) tumors and significantly lower in patients with EO (3.6%) and US (4.7%) tumors. Complications in the gastrointestinal tract group are mainly associated with surgical treatment.

Conclusion. Localization of the malignant neoplasm has a significant impact on the course of coronary heart disease and the choice of treatment method. Surgical revascularization was more often used for gastrointestinal tumors, while endovascular treatment was mainly used for endocrine and urinary tumors. Tumor localization is associated with the risk of complications after myocardial revascularization – with gastrointestinal and RO tumors, complications are more common. The results emphasize the need for an individual approach to patients with cardioncological pathology, which will improve treatment outcomes.
