ABSTRACT

Chronic ischemic heart disease (CIHD) is the leading cause of morbidity and mortality, increasing in proportion to the growth of the older population. Rehabilitative measures in patients who have undergone the myocardial revascularization, with back pain currently have insufficient evidence base. The differentiated program of medical rehabilitation (MR) at the stage of sanatorium-resort treatment is not regulated. A description of the comorbid patients' functional status will create a differentiated system of individual rehabilitation program set up. OBJECTIVE: To develop an algorithm for assessing the functional status of patients after myocardial revascularization with chronic low back pain. MATERIAL AND METHODS: The single-center cross-sectional cohort study (September 2021 - May 2022 yrs) included 50 patients after a myocardial revascularization with chronic low back pain (36 women, 14 men; median age 63.5 [55.5; 67.5] years), who were the study group and 10 patients with CIHD (5 women, 5 men; median age 65.0 [62.0; 68.0] years) who joined the control group. All patients underwent clinical (neurological and therapeutic examination), functional (clinical tests, echocardiography) and laboratory (general and biochemical blood analysis, blood cytokine levels) investigations, the functional class of impairment was defined. RESULTS: There are 4 groups with combined pain syndrome (cardiogenic and vertebrogenic) in different ratios due to different functional and laboratory status among patients after the myocardial revascularization with chronic back pain. The presence of cardiogenic pain syndrome was associated with an increase in leukocyte and peripheral blood glucose levels, interleukin-6, myocardial mass enlargement, while vertebrogenic pain syndrome correlated with personal anxiety. CONCLUSION: The evaluation of the functional status of patients according to the degree of severity of cardiogenic and vertebrogenic pain syndrome has revealed a simple method of pathogenetically based differentiation selection for individual rehabilitation program of patient development.
