The present study focusses on the effects of the diagnostic testing environment on psychological wellbeing, cardiac symptoms and patient satisfaction during cardiac stress testing (CST) in patients who are referred to the Institute Verbeeten for SPECT myocardial perfusion imaging (MPI). The diagnostic procedure consists of two days of MPI using SPECT: day 1 of MPI involves obtaining a resting image and day 2 (typically 3 or 4 days later) a stress MPI following exercise or pharmacological challenge with adenosine. The diagnostic procedure can result in undesirable effects on psychological wellbeing, such as anxiety or psychological distress. These effects can be related to anticipatory anxiety (day 1 of MPI) and/or responses to the exercise or adenosine stress testing (day 2 of MPI). The present investigation aims to develop methods to further improve patients' experiences and wellbeing during the diagnostic process for the presence of inducible myocardial ischemia. This research project will compare four groups to establish the effect of providing information and supportive coaching: (1) care as usual, (2) information support using video materials, (3) supportive coaching during the diagnostic testing procedure, and (4) a combination of both interventions. The video-based information and supportive coaching are aimed at reducing feelings of anxiety, uncertainty and psychological distress during the diagnostic testing procedure. In addition to standardized self-report questionnaires, this project will utilize facial expression analysis software to measure emotional states during CST as well as 24- hour ambulatory assessments to evaluate autonomic nervous system activity, cardiac symptoms and psychological wellbeing during everyday life activities in the period between the two days of MPI. It is hypothesized that additional video-based information and supportive coaching during the diagnostic process for the inducibility of myocardial ischemia will result in improved psychological wellbeing (reduced acute negative emotions; primary outcome) as well as less cardiac and other physical symptoms and improved patient satisfaction (secondary outcomes) of the diagnostic clinic visit. The innovative aspect of the present proposal is its focus on emotional expression during evaluation for myocardial ischemia using FaceReader software in combination with self-reported momentary mood and perceived stress assessments. Knowledge about the interaction between psychological wellbeing and cardiac function obtained in this project will strengthen the development of future interventions aimed to reduce symptom burden and psychological distress in patients undergoing diagnostic evaluations for heart disease.

Comprises of additional visual information in the form of two videos that show details about the procedure on both days of the MPI diagnostic procedure. Each of these two videos are approximately 5 minutes long and are made available to the patients before the first day (video 1), and in between the first and second day (video 2).
Patients receive coaching from one person who is present throughout the complete diagnostic process. The coach is available for answering questions as well as comforting the patients when necessary (e.g., to reassure patients if they are anxious or stressed).
This intervention comprises additional visual information in the form of two videos and coaching throughout the diagnostic process as described above.
Institute Verbeeten
Tilburg, North Brabant, Netherlands
Psychological wellbeing - self report using Profile of Mood States
Will be assessed using self-report measures of emotional states on a scale from 0 to 10 (stressed, anxious, insecure, relaxed, worried, irritated, excited, and tired) with a higher score representing more of this emotional state.These measures of psychological well-being will be compared between the four groups.
Time frame: During the two day diagnostic process.
Psychological wellbeing - Facial expressions of emotions
Will be assessed using facial expression of emotions based on video recordings during the diagnostic testing procedure. Facial expressions will be analyzed (valence and intensity; e.g., anxiety) using FaceReader software as in our prior METC-approved research projects at Institute Verbeeten. A value between 0 and 1 will be the outcome measure for each emotion (happy, sad, angry, surprised, scared, disgusted and neutral). These measures of psychological well-being will be compared between the four groups.
Time frame: During the stress test on day 2.
Cardiac symptoms
The intensity of cardiac symptoms and other common symptoms during MPI SPECT (e.g., headache, dizziness, fatigue, nausea) will be assessed using self-report measures on a scale from 0 to 10. Higher scores represent a higher intensity of the symptoms.
Time frame: During the two day diagnostic process.
Patient experience - PSQ-18
Patient experience and satisfaction of the clinic visit, cardiac tests, and coaching will be assessed using a validated questionnaire with a higher score representing a better patient experience.
Time frame: At the end of the two day diagnostic process.
Physiological measures - heart rate
During the cardiac stress test, heart rate is routinely collected. This data will be used as a physiological measure that is relevant to emotional experiences, cardiac symptoms, and the inducibility of myocardial ischemia.
Time frame: During the cardiac stress test on the second day of the diagnostic process.
Physiological measure - blood pressure
During the cardiac stress test, blood pressure is routinely collected. This data will be used as a physiological measure that is relevant to emotional experiences, cardiac symptoms, and the inducibility of myocardial ischemia.
Time frame: During the cardiac stress test on the second day of the diagnostic process.
Ambulatory ECG monitoring
A 24-hour Holter-ECG will be used to assess heart rate variability during everyday life activities. These assessments are obtained out-of-clinic during the day between the resting and stress MPI SPECT assessment.
Time frame: For 24 hours between the first and second day of the diagnostic process.
SPECT images
As part of the patient's clinical care, single-photon emission computed tomography will be used to obtain myocardial perfusion images on the rest and cardiac stress test days. The presence or absence of ischemia can be evaluated based on these images.
Time frame: At the end of the first and second day of the diagnostic process.
