The phenomenon of complete treatment refusal in patients with acute cerebrovascular accident (according to the LIS-2 registry)

Aim. To describe and analyze a series of cases of absolute non-adherence to treatment (ANA), as well as to study the relationship of the phenomenon of refusal of treatment with long-term adverse outcomes in patients with acute cerebrovascular accident (ACVA), according to the LIS-2 registry (Lyubertsy Mortality Study 2).Material and methods. The study analyzed the results of two stages of prospective follow-up of patients with acute cerebrovascular accident included in the LIS-2 registry (n=960). After 2.8 [2.1; 3.5] years, an examination, a survey, and an assessment of treatment adherence according to the original questionnaire were conducted in 370 patients. After 6.9 [6.1;7.7] years, the outcomes of these patients were evaluated. The survival analysis included death from all causes, nonfatal myocardial infarctions and repeated ACVA, and emergency hospitalization for cardiovascular diseases also. These are the components of the primary combined endpoint.Results. According to the results of the questionnaire, 23 (6,2%) patients replied that they did not take prescribed medications, i.e. they were absolutely not adherent to treatment. Absolutely non-adherent patients smoked more often (p=0.004), were less comorbid, and had statistically significant difference in hypertension and coronary heart disease (CHD) (p
