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.
目前使用西雅图心绞痛问卷（SAQ）评估缺血性心脏病（IHD）的功能状态，这是一种用于监测和预测患者预后的工具。疾病认知（IP）与IHD行为危险因素相关。本研究的目的是确定通过疾病认知问卷（IPQr）评估的不同疾病认知是否能够预测SAQ的任何特征，即确定SAQ是否受到疾病认知的影响和/或偏差。此外，还评估了纽约心脏协会分级和射血分数（EF%）是否是衡量后续是否需要进行支架置入手术的IHD严重程度的预测指标。80名符合经皮冠状动脉介入治疗（PCI）和药物洗脱支架植入条件的IHD患者被要求完成IPQr和SAQ。同时进行实验室分析、超声心动图检查以及冠状动脉诊断和介入手术。IPQr情绪表征可预测SAQ的身体限制。缺血性心脏病功能状态受疾病认知和信念调节。因此，从SAQ得出的关于IHD预后甚至介入指征的一些推论可能存在偏差，并损害SAQ关于身体功能信息的预后可靠性。这也可能对治疗指征产生影响。
