Abstract 17524: Outcome After Resuscitation From Out-of-Hospital Cardiac Arrests During Sport
Background: Out-of-hospital cardiac arrest (OHCA) remains associated with a poor prognosis with 10% being alive after 30 days. Cardiac arrests occurring during sport frequently draw the attention of the media and some may thus refrain from exercising although sport generally is considered to be part of a healthy life style. This study reports the Copenhagen experience with OHCA occurring during sport.
Methods: During an 8½-year period a total of 1,393 consecutive patients with OHCA were admitted with return of spontaneous circulation (ROSC) or on-going resuscitation at hospital arrival after treatment by the physician based Emergency Medical Service in Copenhagen. Pre-hospital data based on Utstein-criteria and data on in-hospital post-resuscitation care were collected by thoroughly reviewing all individual medical charts.
Results: A total of 91 (7%) patients suffered OHCA during sport, 76 (84%) of those were younger than 40 years and 20 (22%) patients younger than 30 years. Mean age was 60±13 vs. 65±15 years in patients with OHCA in general, p<0.001. Patients with OHCA during sport were frequently male (97% vs. 69%, p<0.001), had shorter time to ROSC (10 min (IQR: 5-19) vs. 15 (10-22), p<0.001) and the primary rhythm was more frequently shock-able (79% vs. 47%, p<0.001) compared to patients with OHCA in general. Cardiac etiology was the predominant cause of OHCA during sport (88 (97%) vs. 980 (80%), p<0.001) with 54 (61%) vs. 474 (39%) (p<0.001) patients suffering from acute myocardial infarction. One-year mortality was 25% vs. 65% (p<0.001), Figure 1, corresponding to an adjusted hazard ratio (HR) for OHCA during sport of 0.27 (95%CI: 0.14-0.50, p<0.001).
Conclusion: OHCA occurring during sport is associated with a significantly lower mortality even after adjusting for confounding factors. Even though cardiac arrest can occur during sport our study shows that the prognosis after OHCA is significantly better compared to patients suffering arrests in other situations.
