Differences in Attitudes and Barriers Towards Advance Care Planning Amongst Ischemic Heart Disease Patients: A Cross-Sectional Study

Objectives Perceptions towards advanced care planning (ACP) amongst individuals with Ischemic Heart Disease before or after a life-threatening Acute Myocardial Infarction event is underexamined and could impact the appropriate timing for ACP advocacy. This cross-sectional study assessed awareness and intentions regarding ACP in individuals with Ischemic Heart Disease, both before and after an Acute Myocardial Infarction, and explored the motivating effect of a near-fatal Acute Myocardial Infarction event on its engagement. Methods This study was conducted from 24 August 2021 through 13 March 2023, whereby patients were administered a one-time questionnaire with no follow-up required. Patients with either chronic Ischemic Heart Disease (group A) or a recent Acute Myocardial Infarction event (group B) were recruited from the outpatient National University Heart Centre, Singapore. Results 101 patients (n = 51 for Group A, n = 50 for Group B) were recruited. Mean age (SD) was 59 (10.5) years and 84 were male (83.2%). Between both groups, patients in group B reported significantly higher scores on ‘Lack of information’ and ‘Self-efficacy’ domains, and had no ACP awareness nor plans of doing an ACP compared to group A. ACP awareness was the sole significant predictor of intentions of doing an ACP in the final regression model ( P < .05). Conclusions Interestingly, this study suggests that surviving a potentially life-threatening heart condition did not result in higher intention of doing an ACP. Thus, advocacy of ACP in the community should simply start by raising awareness levels widely and may not need to be focused on individuals’ state of health.
