(1) Background: Infective endocarditis (IE) is a disease of the endocardial surface of the heart, caused by infection of the native or prosthetic valve or an indwelling cardiac device. Apart from IE predisposing risk factors that include heart conditions and medical procedures, the novel trajectories from demographic factors to perceived stress conditions have been under investigation in recent years. The aim of the present study was to evaluate the associations between perceived stress and demographic characteristics as well as clinical forms of IE among survivors of IE in Kaunas, Lithuania. (2) Methods: A cross-sectional study among IE cases (n = 135) at the Lithuanian University of Health Sciences Kaunas Clinics Cardiology department during the period 2014-2017 was performed. Data about IE clinical features, sociodemographic characteristics and perceived stress level (Perceived Stress Scale (PSS-10)) upon diagnosis were collected. Package "SPSS 25.0" was used in the statistical analysis. Logistic regression analysis was performed including gender, previous occupation, place of residence and clinical forms of IE in the analysis of perceived stress among survivors of IE. The STROBE checklist for cross-sectional studies was used in this study. (3) Results: Perceived stress was experienced by 54.8 percent of the respondents. In the final model, the OR (odds ratio) of perceived stress for females was 2.07 as compared to men; for rural residents, the OR was 2.25 as compared to urban residents. These results were statistically significant. A tendency for increased OR of perceived stress for low-skilled workers as compared to high-skilled ones and classical IE clinical form as compared to non-classical form was observed, but these results were not statistically significant. (4) Conclusions: The present study is an attempt to focus the attention of IE researchers on the effects of psychological state in the disease development. Differences in perceived stress and some demographic characteristics, as well as tendencies of IE clinical forms, were observed among survivors of IE in Kaunas, Lithuania.
