Abstract Introduction A minimal delay from symptom onset to reperfusion therapy is essential in the management of acute myocardial infarction (AMI). The patient's response to initial symptoms (patient delay) substantially affects the delay. Nevertheless, predictors of patient-related delays are less clear. The aim of the study was to compare knowledge and awareness of heart attack symptoms and reactions to it in a general Polish population. Methods In this cross-sectional study, 1 376 persons aged 18 years or older enrolled in an Internet survey (computer assisted web interview, CAWI). Heart attack knowledge, self-efficacy for recognizing and responding to heart attack symptoms, and perceived risk for a future heart attack were measured. Primary exclusion criteria were: prior MI or family history of MI. The survey was carried out as a part of the nationwide “Heart attack – time is life” Campaign. Results Based on the Polish Registry on Acute Coronary Syndromes (PL-ACS) the median total ischemic time in Poland is 260 minutes, whereas the median patient delay is 142 minutes. The main factors associated with long time delays include interhospital transfers, symptoms presentation during the night, age >65 years, inhabitants of rural areas, diabetes mellitus, first-ever MI, female sex. The survey demonstrated that 73.8% of respondents recognize that chest pain may be associated with MI, but only 22.2% of them would call the emergency medical services. Age-, sex-, income-, and education-related responses are depicted in the Figure. Only 23% of these respondents would make the call immediately, whereas 31.7% would wait at least 3–4 hours (in some cases event until the next day). 66.4% of the surveyed population would ignore the chest pain main reason being “nothing serious” or “a result of extreme emotions”. Notwithstanding, the majority of the surveyed population is aware of the seriousness of the AMI-related complications (heart failure, disability, rehospitalizations, death). Conclusions These findings highlight the urgent need to develop effective, tailored campaigns to close the knowledge gap and, primarily, to educate the Polish society about the correct response to chest pain. Young age, higher education, and high income were not predictors of common sense and correct responses.
