Purpose: The purpose of this study is to report the prevalence of treatable CAD and outcomes for resuscitated patients without STE at hospital admission.
Methods: Retrospective OHCA database analysis from 2005 to 2015 in a tertiary care center. All OHCA patients > 18 years with presumed cardiac cause and sustained ROSC without STE at admission were included. Primary endpoint was defined as good neurological survival at 30 days after ROSC.
Based on coronary arteries examination results, patients were categorized in ‘manifest CAD’ or ‘no manifest CAD’.
Results: During the study period 645 (55.1%) out of 1170 screened patients could be included. Coronary angiography was done in 343 (53.2%) patients. Manifest CAD was found in 214 (62.4%) patients. Coronary intervention, thrombus aspiration or coronary artery bypass grafting were feasible in 152 (71.0%) patients. Detailed baseline characteristics are expressed in table 1.
The highest survival rates were found in the ‘no manifest CAD’ group (90.7%), although survival for patients with ‘manifest CAD’ (76.6%, p<0.001) was also higher than without CAG (44.7%, p<0.001).
Conclusions: The high prevalence of CAD and a rather high rate of successful coronary interventions emphasizes the recommendations to catheterize all patients without ST-elevations in the absence of obvious non-cardiac causes immediately.
