Introduction. Conscious implementation of a therapeutic plan immediately after discharge from hospital is pivotal in myocardial infarction survivors. Obesity and overweight are known as factors increasing the risk of adverse cardiovascular events and worsening long-term clinical outcome. The aim of the study was to assess the knowledge regarding cardiovascular diseases in patients with myocardial infarction undergoing in-hospital brochure-based education in relation to the prevalence of overweight and obesity. Patients and methods. A prospective, single-centre, cohort, observational study was conducted in 228 patients hospitalised due to myocardial infarction (women n = 52, men n = 176). A dedicated questionnaire containing 20 single-choice questions was applied for the knowledge assessment. Patients were divided into three groups depending on the BMI level (normal, overweight, obesity). Results. Comparison of patients’ knowledge at baseline and on the day of discharge revealed a significant increase of overall result (p = 0.0264) and of knowledge about prophylaxis (p = 0.0115). Multivariate analysis showed education level (-5.82 ± 2.576, p = 0.025) and BMI (-4.54 ± 1.771, p = 0.011) as independent factors determining the overall increase in patients’ knowledge. Conclusions. Educational interventions in overweight and obese patients should be intensified. The brochure is an effective educational tool.
