Abstract

Introduction: There is limited published data on the burden of cardiac disease among patients requiring emergency medical evacuation from the Great Barrier Reef, a popular tourist destination in Far North Queensland, Australia. The aim of this study was to examine the characteristics and outcomes of patients with cardiac conditions who were retrieved from the northern Great Barrier Reef to Cairns Hospital. Methods: This observational study was a planned substudy of a broader analysis of medical retrievals from the Cairns/Cooktown section of the Great Barrier Reef. It included all patients retrieved to Cairns Hospital between July 2016 and January 2020 who were assigned a cardiac diagnosis during their hospital stay. Data were collected about electrocardiograph, cardiac troponin blood test and invasive coronary angiography results as well as final hospital diagnosis. Results: During the study period, 120 patients were retrieved from the Great Barrier Reef to Cairns Hospital, of which 46 (38%) were subsequently diagnosed with a primary cardiac condition(s) or other disease process with clinically significant cardiac involvement. The most common diagnoses were type 2 myocardial infarction (20; 16.7% of all retrievals), primary cardiac arrhythmia (14; 12.5%) and acute coronary syndrome (5; 4.2%). An elevated troponin was recorded in 30% of all retrievals and in 78% of those with a cardiac diagnosis. A total of 14 (30.4%) of patients with a cardiac diagnosis died during their hospital admission. Invasive coronary angiography was performed in 18 cases, of which six patients had obstructive coronary artery disease. Four patients required percutaneous coronary intervention. Conclusion: A high proportion of patients retrieved to Cairns Hospital from the Great Barrier Reef were diagnosed with a primary cardiac condition. This data may assist tourism operators, retrieval organisations and health services to plan for, and respond to, cardiac events among visitors to the reef.
