Key result
PCI for acute MI is linked to ~84% lower illness perception scores versus non-PCI.
Why the study?
Patients receiving PCI for AMI have low attendance at cardiac rehabilitation, hypothesized to stem from a benign perception of their coronary disease that had not been quantitatively investigated.
Does percutaneous coronary intervention alter illness perceptions in patients with acute myocardial infarction attending cardiac rehabilitation?

Absolute Event Rate: 1.62% vs 9.94%
p-value: p=0.027
Patients receiving PCI for acute myocardial infarction have a more benign perception of their disease compared to non-PCI patients, which may contribute to poor cardiac rehabilitation attendance.
PCI for AMI was associated with more benign illness perceptions; hypothesis-generating for effects on rehabilitation attendance, needing prospective confirmation.
PURPOSE: Patients who receive percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) have been found to have low attendance at cardiac rehabilitation (CR). It has been suggested that this is because PCI patients have a benign perception of their coronary disease; however, this has never been quantitatively investigated. The aim of this prospective study was to evaluate the illness perceptions (IP) of patients with AMI treated with PCI. METHODS: The Heart Health Illness Perception Questionnaire (modified version of the Brief Illness Perception Questionnaire) and the Cardiac Beliefs Questionnaire were used to assess patients' IP and cardiac disease misconceptions, respectively. Patients in phase 2 of CR were recruited from the Royal Alexandria Hospital, Paisley, UK. One hundred two patients were identified from the cardiac unit database over a 16-week period and sent questionnaires. RESULTS: Fifty-six patients returned questionnaires suitable for analysis (54.9% response rate). There was a significant difference in the IP scores of the 3 groups [primary-PCI (pPCI) = 0.18 ± 1.44, elective-PCI = 5.27 ± 15.65, non-PCI = 9.94 ± 11.19; P = 0.046]. PCI patients had a significantly lower IP score than non-PCI patients (PCI = 1.62 ± 12.76, non-PCI = 9.94 ± 11.19; P = 0.027). pPCI patients had a significantly lower IP score than non-pPCI patients (pPCI = 0.18 ± 11.44, non-pPCI = 8.04 ± 13.11; P = 0.021). Of the PCI patients 22.9% agreed they were 'fixed for life' and a lower IP score was found to predict this opinion (P = 0.032). CONCLUSION: PCI patients, particularly pPCI patients, perceive their coronary disease to be relatively benign. Further research is required to investigate if this predicts poor attendance at CR.

McCallum et al. (2023) conducted an observational in Acute myocardial infarction (n=56). Percutaneous coronary intervention (PCI) vs. No percutaneous intervention (non-PCI) was evaluated on Illness perception (IP) score (p=0.027). Patients treated with PCI for acute myocardial infarction had significantly lower illness perception scores than non-PCI patients (1.62 vs 9.94; P=0.027), perceiving their disease as more benign.
