title: [Post-anoxic encephalopathy after an episode of aborted sudden cardiac death].
abstract: OBJECTIVE
  The presence of post-anoxic encephalopathy after an episode of aborted sudden cardiac death is a serious medical and social problem.
  
  
  METHODS
  Of 193 patients admitted to the coronary unit during a 12-year period with aborted sudden cardiac death, 104 died (54%) and 89 survived the episode (46%). We compared the characteristics and 6-month prognosis between survivors according to the presence or absence of post-anoxic encephalopathy.
  
  
  RESULTS
  Of 89 survivors, 38 patients were discharged alive with post-anoxic encephalopathy (42%) and 51 were discharged without neurological disturbances (58%). Patients with post-anoxic encephalopathy were older (65 13.6 vs. 59 12.9 years; p = 0.04). Mean time to care for cardiac arrest was 11.14.9 min in the post-anoxic encephalopathy group, versus 3.43 min (p < 0.01). The first documented rhythm was VF/VT in 57% and asystolia in 29% in the post-anoxic encephalopathy group, vs. 88% and 3% (p = 0.02). More than half (58%) of the patients in the post-anoxic encephalopathy group had coronary artery disease, vs. 49% (p = NS). Slightly more than half (52%) of the patients in the post-anoxic encephalopathy group had infectious complications, vs. 21% (p = 0.01). After 6 months of follow-up, mortality in patients discharged with post-anoxic encephalopathy was 62%, vs. 10% (p < 0.01); 21% of then showed significant functional improvement and 18% remained neurologically stable.
  
  
  CONCLUSIONS
  Most patients admitted to a coronary unit with aborted sudden cardiac death died during hospitalization. Almost half of the survivors had post-anoxic encephalopathy at discharge; of these patients, 62% died within the following 6 months, and functional status improved only in a minority of them.
