Cognitive impairment and depression are often associated with acute myocardial infarction, however, the risk factors for their occurrence after myocardial infarction are still unclear. To determine the effect of reduced ejection fraction and demographic characteristics on the occurrence of cognitive impairment and depression after myocardial infarction. In the prospective study, the final sample consisted of 82 patients. Based on the value of the ejection fraction, the patients were divided into those with a value of < 40% and those having a value of ≥ 40%. Demographic data (age, gender, education), and data on comorbidities, were collected from the patients’ medical history. The instruments of studies were: Mini-mental test and Beck depression inventory. The occurrence of cognitive impairment and depression was not, to a significant degree, associated with the level of ejection fraction. In contrast, demographics have shown positive predictive effects. Among demographic characteristics, the age of the patient proved to be a significant predictor for the occurrence of cognitive impairment (p = 0.004). The probability of cognitive impairment increases 1.16 times for each year of life. Significant depression predictor was female gender (p = 0.014). The probability of depression was 3.5 times greater for female gender. Cognitive impairment after acute myocardial infarction is more common in older patients, and depression in more common in women.
