Coronary artery diseaseAngiographic Characteristics of Coronary Disease and Postresuscitation Electrocardiograms in Patients With Aborted Cardiac Arrest Outside a Hospital
Section snippets
Methods
This retrospective study was performed at University Medical Center, Ljubljana and complied with the Declaration of Helsinki. The research protocol was approved by the Slovenian national ethics committee. Consecutive patients with out-of-hospital cardiac arrest of presumed cardiac origin and re-establishment of spontaneous circulation (ROSC) in the field who underwent urgent coronary angiography from January 1, 2003 through December 31, 2008 were investigated. Decision for urgent coronary
Results
During the study period 335 consecutive patients who had been resuscitated after out-of-hospital cardiac arrest were admitted (Figure 2). Because of exclusion criteria 158 of 179 patients with STEMI (88%) and 54 of 156 patients with non-STEMI (35%) underwent urgent coronary angiography. The 2 groups were comparable in general characteristics except for a greater incidence of previous coronary disease in patients without STEMI who had also a longer interval from collapse to advanced life support
Discussion
Our study confirmed the high incidence of obstructive coronary artery disease and the presence of ≥1 coronary occlusion in patients with aborted sudden cardiac death.1, 2, 5, 10, 11, 12 Because STEMI on postresuscitation ECG was associated with the presence of a presumed acute culprit lesion in almost 90% of cases, false-positive findings were uncommon. However, an acute lesion was found also in 24% in the absence of STEMI, which argues for an urgent invasive coronary strategy in this subgroup.
