  1. Table 1 shows the clinical characteristics of all resuscitated patients (n = 77), cardiac control patients (n = 50) and healthy controls (n = 50) that were included into measurement of plasma selenium levels. Cause of cardiac arrest was defined as any underlying cardiac disease leading to cardiac arrest, or hospital admission, respectively (for example, coronary artery disease (chronic or acute), heart failure, rhythmic disturbances). CPR, cardiopulmonary resuscitation; CAD, coronary artery disease; PCI, percutaneous coronary intervention; VT, ventricular tachycardia; VF, ventricular fibrillation; PEA, pulseless electrical activity; GOS, Glasgow outcome scale; SOFA, sequential organ failure assessment; ROSC, return of spontaneous circulation.
