Abstract

Objective: This study aimed to investigate the association between coronary angiography (CAG) with and without percutaneous coronary intervention (PCI) after out-of-hospital cardiac arrest (OHCA) and neurological recovery and to determine the influence of primary electrocardiogram or patient age on the effects of CAG. Methods: Adult patients with OHCA with cardiac etiology who were admitted to PCI-capable hospitals from 2016 to 2017 were enrolled in this study from the nationwide OHCA registry of Korea. Coronary intervention was categorized into three groups: No CAG, CAG without PCI, and CAG with PCI. The endpoint was good neurological recovery. Multivariable logistic regression and interaction analyses (intervention × electrocardiogram and intervention × age) were conducted by calculating adjusted odds ratios (aORs) and 95% confidence intervals (CI). Results: Of a total of 6,802 eligible OHCA patients, 1,218 (17.9%) underwent CAG without PCI and 1,136 (16.7%) underwent CAG with PCI. The CAG without PCI and CAG with PCI groups were more likely to have good neurological recovery than the No CAG group (57.4% vs. 61.6% vs. 16.3%; 3.39 [2.83–4.06] for CAG without PCI and 3.32 [2.74–4.01] for CAG with PCI). Interaction analysis showed that although the effect size differed according to patient characteristics, both CAG groups were associated with an increased likelihood of good neurological recovery, regardless of primary electrocardiogram and age group. In younger patients, CAG with PCI had greater outcome benefits than CAG without PCI (8.54 [4.31–16.95] vs. 4.10 [2.69–6.24]), whereas CAG without PCI had a larger effect size than CAG with PCI in elderly patients (4.46 [2.59–7.68] vs. 2.92 [1.80–4.73]) (p value for interaction 0.02). Conclusions: Post-resuscitation CAG with and without PCI are associated with better neurological recovery in patients with OHCA, regardless of primary electrocardiogram and patient age.
