The functional status of ischemic heart disease (IHD) is currently assessed using the Seattle Angina Questionnaire (SAQ), a tool for monitoring and predicting the patient’s prognosis. Illness perceptions (IP) are associated with IHD behavioral risk factors. The aim of the study was to find whether different IP, as evaluated by the IP Questionnaire (IPQr), can predict any of the features of the SAQ, i.e., to determine whether the SAQ is influenced and/or biased by illness perceptions. Moreover, whether New York Heart Association class and Ejection Fraction (EF%) are predictors of IHD severity measured as need of subsequent stenting procedures was also assessed. Eighty IHD patients eligible for percutaneous coronary intervention (PCI) and drug-eluting stent implant were asked to complete the IPQr and the SAQ. Laboratory analyses, echocardiography, and coronary diagnostic and interventional procedures were performed concurrently. Physical limitations of the SAQ are predicted by IPQr emotional representation. Ischemic heart disease functional status is regulated by illness perceptions and beliefs. Thus, some of the inferences drawn from the SAQ regarding IHD prognosis and even interventional indications may be biased and compromise the prognostic reliability of the SAQ information on physical function. This can also have consequences for therapeutic indications.
