ABSTRACT
BACKGROUND: To assess health-related quality of life (HRQL) in Kazakh patients (n=285) treated in Cardiology Department of the Emergency Hospital of Semey during 2012 with acute myocardial infarction and to compare results with HRQL measured in 21 countries (n=3,847). METHODS: Telephone interviews survey was conducted in February 2014 with the Russian translation of Minnesota Living with Heart Failure Questionnaire (MLHFQ). Descriptive statistics were used to characterize the sample according to each single item of MLHFQ and grouping them in three subset concerning physical, emotional, and social environment dimensions of patients' life. The distribution of scores was evaluated in terms of floor and ceiling effects; Cronbach's alpha coefficient was calculated for the different dimensions to assess internal consistency. RESULTS: Mean age of sample is 60.8 years, most of patients are male (71.6%) and retired (43.5%). The total MLHFQ score was generally low at a moderate degree (mean 34.7, range 0-105). Physical dimension score (mean 14.92) shows mild to moderate impairment in HRQL and a better perception than the average of the control countries (14.9 vs 16.6); emotional status (mean 4.8) is moderately adequate and better than the controls (4.8 vs 7.2); social environment (9.82) showed significant impairment of HRQL and a worse evaluation (9.82 vs 7.8). CONCLUSIONS: Kazakh patients reported better emotional and physical HRQL as consequence of the social structure where family environment promotes emotional support and improves self-care, social environment affects the total MLHFQ score that is low and related to the requested availability of free medicines.
