Lagedala R, Elfwénb L, Jonssonc M, et al. - Researchers conducted a retrospective study of out-of-hospital cardiac arrest patients to delineate coronary artery findings after cardiac arrest in relation to ECG and comorbidity. They assessed ECG and angiography information of 1,133 patients (mean age: 64 years). and identified a shockable rhythm in 79%. Among cardiac arrest patients without ST-elevation who underwent coronary angiography, the total incidence of any significant stenosis was 71% within 28 days. In patients with normal ECG, the incidence of any stenosis was 62.1% and in patients with LBBB, 59.3%. PCI attempts were made in 47.1% and 42.4% among patients with ST-depression or RBBB, respectively, compared with 33.3% in patients with normal ECG. Among patients without ST-elevation, at least one significant stenosis was observed in 84.8% with diabetes mellitus and in 71.5 of those with initial shockable rhythm. Findings thereby suggest the significance of evaluation of ECG patterns and comorbidities in out-of-hospital cardiac arrest patients without ST-segment elevation for recognizing those with a high risk of coronary artery lesions that could benefit from early revascularization.
