15-year survival of comatose OHCA patients according to initial rhythm

Abstract

Abstract Introduction Long-term outcome of comatose survivors of out-of-hospital cardiac arrest (OHCA) is largely unknown. We therefore investigated 15-year survival of consecutive patients who were admitted to our hospital after reestablishment of spontaneous circulation (ROSC) on the field. Methods and results Between January 2003 and January 2022, 851 patients with shockable and 247 patients with non-shockable rhythms were admitted. Patients with shockable rhythm were significantly younger (61.5±13,3 versus 66.8±14.8 years), had more often bystander life support (64% versus 35%), shorter delay to emergency team arrival (7.3±5.1 versus 8.3±5.9 minutes), shorter time from advanced life support to ROSC (16.6±15.27 versus 18.5±14.3) and more aggressive hospital treatment including hypothermia (89% versus 74%), coronary angiography/PCI strategy (81% versus 52%) and more IABP/ECMO support (18% versus 10%). Survival with good neurological outcome in patients with shockable rhythm decreased from 51% at hospital discharge to 35% at 15 years (Figure 1). In patients with non-shockable rhythm, survival decreased from 14% at hospital discharge to 8% at 15 years. Conclusion If comatose OHCA patient survives to hospital discharge, annual death rate during the following 15 years is 1.07% for shockable and 0.40 for non-shockable rhythms indicating good long-term outcome.
