Abstract

BACKGROUND: Consciousness disturbance is one of the major clinical signs associated with shock state, but its prognostic value has not been previously evaluated in cardiovascular shock patients. We aimed to evaluate the prognostic value of neurological status for 30-day mortality in cardiovascular shock patients without out-of-hospital cardiac arrest (OHCA). Methods and Results: Patients with out-of-hospital onset cardiovascular shock were recruited from the Japanese Circulation Society Shock Registry. Neurological status upon hospital arrival was evaluated using the Japan Coma Scale (JCS). Patients were divided into 4 groups according to the JCS: alert, JCS 0; awake, JCS 1-3 (not fully alert but awake without any stimuli); arousable, JCS 10-30 (arousable with stimulation); and coma JCS 100-300 (unarousable). The primary endpoint was 30-day all-cause death. In total, 700 cardiovascular shock patients without OHCA were assessed. The coma group was associated with a higher incidence of 30-day all-cause death compared with other groups (alert, 15.3%; awake, 24.4%; arousable, 36.8%; coma, 48.5%, P<0.001). Similar trends were observed in etiologically divergent subgroups (acute coronary syndrome, non-ischemic arrhythmia, and aortic disease). On multivariate Cox regression analysis, arousable (hazard ratio [HR], 1.82; 95% CI: 1.16-2.85, P=0.009) and coma (HR, 2.72; 95% CI: 1.76-4.22, P<0.001) (reference: alert) independently predicted 30-day mortality.

CONCLUSIONS: Neurological status upon hospital arrival was useful to predict 30-day mortality in cardiovascular shock patients without OHCA.
