Popis: Impaired cardiac autonomic function has been linked to adverse outcomes in patients with acute coronary syndromes (ACS) but is not included in clinical risk models. This is the first study to investigate whether point-of-care testing of cardiac autonomic function by means of short-term deceleration capacity (DC) of heart rate improves risk assessment in patients with suspected ACS. 1821 patients with suspected ACS were prospectively enrolled if they were older than 17 years and in sinus rhythm. Short-term DC was automatically assessed from monitor recordings at hospital admission. The Global Registry of Acute Coronary Events (GRACE) score was used as gold standard risk predictor. Primary endpoint was the composite of intrahospital and 30-day mortality. Secondary endpoint was 180-day mortality. Of the 1,821 patients with suspected ACS, 28 (1.5%) and 60 (3.3%) reached the primary and secondary endpoints, respectively. DC was a highly significant predictor of both endpoints, yielding areas under the curve (AUC) of 0.784 (95% CI 0.714–0.854) and 0.781 (0.727–0.832) (p
