The factors of quality of life among patients after myocardial infarction in Poland: a cross-sectional study. The quality of life among patients after myocardial infarction.

The quality of life (QoL) is now recognised as a central indicator of the effectiveness of interventions especially in patients after myocardial infarction (MI). The QoL may be important predict poor outcomes in cardiac patients.The present work aims to increase knowledge of the level of QoL in patients after MI. Moreover, the paper analyses the QoL in relation to sociodemographic factors and the degree of functioning in chronic disease. The study was conducted among 231 patients who were hospitalized due to MI within the period of June 2021 to June 2022 in the Hospital in Racibórz in Poland. The WHO Quality of Life Questionnaire and the Chronic Disease Functioning Scale were used. The analysis showed a statistically significant correlation (coefficient value 0.5 <|r/rho|≤ 0.7) between general functioning in chronic disease and the average QoL (rho = 0.56; p < 0.001)and somatic QoL levels(rho = 0.52; p < 0.001), as well as a moderately strong positive correlation with the QoL level on the psychological domain (rho = 0.50; p < 0.001), social domain(rho = 0.48; p < 0.001) and environmental domain (rho = 0.43; p < 0.001). The results of this study suggested that healthcare workers adopts appropriate policies for the implementation of quality of life, which can reduce the number of repetitive referrals to the hospital and costs imposed on the health system.
