Abstract

Medical and Health Sciences Psychology and Cognitive Sciences coronary angiography coronary revascularisation heart disease psychological distress service use
Objective: Cardiac patients with psychological distress have a poorer prognosis than patients without distress; which may in part reflect differences in treatment. We quantified variation in coronary angiography and revascularisation procedures according to psychological distress among patients admitted with incident acute myocardial infarction (AMI) or angina. Methods: Questionnaire data (collected 2006-09) from 45 and Up Study participants were linked to hospitalisation and mortality data, to 30 June 2016. Among patients free from ischaemic heart disease at baseline and subsequently hospitalised with AMI or angina, Cox regression was used to model the association between distress (Kessler-10 scores: low [10-<12], mild [12-<16], moderate [16-<22] and high [22-50]) - assessed on the questionnaire - and coronary angiography and revascularisation procedures (percutaneous coronary intervention [PCI] or coronary artery bypass grafting [CABG]) within 30 days of admission, adjusting for personal characteristics, including physical functioning. Results: Proportions receiving angiography and PCI/CABG were 71.4% and 51.7% following AMI (n = 3749), and 61.3% and 31.3% for angina patients (n = 3772), respectively. Following AMI, age-sex-adjusted rates of PCI/CABG were lower with higher levels of distress (test for trend: p = .037), as were rates of angiography and PCI/CABG (p < .01) following admission with angina. After additional adjustment for personal characteristics, associations between distress and procedure rates attenuated substantively and were no longer significant, except that PCI/CABG rates remained lower among angina patients with high versus low distress (HR = 0.76,95%CI:0.59-0.99). Conclusion: Distress-related variation in coronary procedures largely reflects differences in personal characteristics. Whether lower revascularisation rates among angina patients with high compared to low distress are clinically appropriate or represent under-treatment remains unclear.
