Research on adherence of elder patients with cardiovascular diseases to surgical treatment and assessment of the endovascular treatment clinical efficacy [Исследование приверженности пациентов с сердечно-сосудистыми заболеваниями старших возрастных групп хирургическому лечению и оценка клинической эффективности рентгенэндоваскулярного лечения]

Background. Patients with cardiovascular diseases (CVD) older than 70 years have low adherence to surgical treatment. Aim. To investigate the adherence of elder patients with CVD to surgical treatment and evaluate the effectiveness of endovascular care. Material and methods. In 2016-2020 on the basis of the vascular surgery department of the Central Clinical Hospital “Russian Railways-Medicine” (Moscow) and the Peoples' Friendship University of Russia standardized clinical interviewing of patients with surgical CVD (n=422, average age 76.11±7.2 years) was conducted. Patients were considered adherent to surgical treatment if more than in 90% of cases they agreed to undergo cardiovascular surgery. Endovascular operations were performed (100%). Evaluation of the endovascular treatment effectiveness was carried out according to the following criteria: reducing the degree of ischemia, the duration of hospital treatment, the frequency of hospitalizations during the year caused by the CVD progression, and two-year survival. The duration of patients' supervision was 24 months. We compared the results of the years 2016-2017 (the period of mainly conservative treatment, group A, n=106) and the years 2018-2019 (the period of high surgical activity for CVD, group B, n=422 which included 106 patients from group A). Differences between the compared indicators were considered significant at p
