MI – myocardial infarction, CVA – cerebrovascular accident, Supraventricular arrhythmia – atrial fibrillation or atrial flutter, Ventricular arrhythmia – ventricular tachycardia or fibrillation, Renal failure – increase of serum creatinine > 80 mmol/l with or without need for temporary dialysis, Infection – infection of respiratory or urinary system, Cognitive impairment – psychomotor agitation with the necessity of therapeutic intervention, Ventilation problems – symptoms of partial and/or global respiratory failure with or without need for reintubation, ICU – intensive care unit.
