ObjectivesWe aimed to identify whether the availability of catheter laboratory affects clinical outcomes of out-of-hospital cardiac arrest (OHCA) complicating myocardial infarction (AMI).MethodsPatients admitted with a diagnosis of AMI and OHCA from the Myocardial Ischaemia National Audit Project (MINAP) between 2010 to 2017 were stratified into three groups based on initial hospital's catheter laboratory status: hospitals without a catheter laboratory (No-catheter lab hospitals), hospitals with diagnostic catheter laboratory (Diagnostic hospitals), and hospitals with PCI facilities (PCI hospitals). We used multivariable logistic regression to evaluate factors associated with clinical outcomes.ResultsWe included 12,303 patients of which 9,798 were admitted to PCI hospitals, 1,595 to no-catheter lab hospitals, and 910 to diagnostic hospitals. Patients admitted to PCI hospitals were more frequently reviewed by a cardiologist (96%, p < 0.001) than no-catheter lab hospitals (80%) and diagnostic hospitals (74%), and more likely to receive coronary angiography (PCI hospitals (87%), diagnostic hospitals (31%), no-catheter lab hospitals (54%), p < 0.001). They also were more likely to undergo PCI (PCI hospitals (42%), diagnostic hospitals (17%), no-catheter lab hospitals (17%), p < 0.001). After adjustment, there was no significant difference in the in-hospital mortality (OR 0.76, 95% CI 0.55-1.06) or re-infarction (OR 1.28, 95% CI 0.72-2.26) in patients admitted to PCI hospitals nor in patients admitted to diagnostic hospitals (mortality (OR 1.28, 95% CI 0.72-2.26), re-infarction (OR 1.38, 95% CI 0.68-2.82)).ConclusionThere is variation in coronary angiography use between hospitals without a catheter laboratory and PCI centres, which was not associated with better in-hospital survival.Copyright © 2021 Elsevier B.V.
