Background: While short-term prognosis of cardiac arrest (CA) patients has been extensively studied, less is known regarding the mid- and long-term outcome of survivors.
Aims: The aim of the DESAC study was to describe mid- and long-term survival and neurological status of CA survivors, and to assess the influence of pre- and intra-hospital therapeutic strategies on these outcomes.
Methods: Between Jul 2015 and Oct 2018, patients over 18 years who were discharged alive from intensive care units in Paris and suburbs (France) after a non-traumatic CA were included and interviewed every 6 months during at least 24 months and up to 48 months in this multicentric study. Factors associated with Cerebral Performance Category (CPC) scale at 24 months were assessed with logistic regression, with CPC 1 or 2 level considered as a favorable neurological outcome. Trajectories of CPC were derived by mixed linear model in survivors with at least 3 evaluations.
Results: Out of 593 survivors, 525 had a 24 months follow-up (mean age 57.6 +/-15.3, 79% men). CA occurred in public location in 251/525, with an initial shockable rhythm in 392/525. Prognostic factors independently associated with a favorable neurological outcome at 24 months were initial shockable rhythm (OR= 3.53 (1.65; 7.58)) and previous practice of sport (OR= 3.12 (1.20 ; 8.11)), whereas older age (OR per 10 years= 0.52 (0.40; 0.68)) and previous ischemic cardiomyopathy (OR= 0.34 (0.15 ; 0.77)) were poor prognostic factors. Therapeutic hypothermia or coronary procedures were not related to prognosis. Five trajectories of CPC could be derived among the 514 patients. Overall, 64% remained in CPC1, 13% in CPC2, 11% improved from CPC2 to CPC 12% died either early or lately (Figure 1).
Conclusions: In this multicentric and prospective study, practice of sport and shockable rhythm were strongly associated with a favorable neurological recovery at 24 months. Furthermore, two thirds of the survivors remained in CPC 1 over time.
