NCT05830422

Brief Summary

The objective of this observational study is to provide basic data for predicting and analyzing the occurrence and causes of delayed cognitive impairment, an important factor in the quality of life, among discharged patients who have received targeted temperature management therapy and experienced favorable neurological outcomes after out-of-hospital cardiac arrest. The main questions it aims to answer are:

  • Can we identify abnormal areas in the brains of patients with delayed cognitive impairment using Brain MRI or positron emission tomography (PET) imaging?
  • Is it possible to predict delayed cognitive impairment using biomarkers?

Outcome Measures

Primary Outcomes (1)

  • Change in cognitive impairment

    Through the Seoul Neuropsychological Screening Battery (SNSB), attention, language and related functions, visuospatial function, memory, frontal lobe and executive function, and other related functions can be assessed. The test is conducted by a specialist clinical psychologist for 1 hour and 30 minutes to 2 hours, and the results are analyzed by Professor Oh Eung-Seok, a neurologist.

    at 10-14 days, 3 months, and 6 months after return of spontaneous circulation

Study Arms (1)

Good neurological outcome

Patients who showed good neurological outcomes with CPC scores of 1-2 at discharge

Other: nothing

Interventions

nothingOTHER

Follow-up observation was conducted without any intervention in an outpatient setting.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

For subjects who survived after out-of-hospital cardiac arrest, the prognosis was evaluated 10-14 days after ROSC using CPC. For CPC 1-2, neurological prognosis was evaluated as good, and for CPC 3-5, neurological prognosis was evaluated as poor. Only cases of CPC 1-2 between 10 and 14 days after ROSC were included in this study.

You may qualify if:

  • Patients who visited the hospital emergency room due to cardiac arrest within 60 months after Institutional Review Board (IRB) approval
  • Patients with Glasgow Coma Scale (GCS) less than 8 points after spontaneous circulation recovery
  • Patients who are 18 years old or older
  • Patients who underwent targeted temperature management (TTM)
  • Patients who showed good neurological outcomes with CPC 1-2 points after evaluating the prognosis on days 10-14 after ROSC

You may not qualify if:

  • Under 18 years of age
  • cardiac arrest cause is trauma
  • Patients who have not undergone targeted temperature management
  • Patients treated with extracorporeal membrane oxygenation (ECMO)
  • Patients who were not able to undergo SNSB testing
  • Patients who could not be followed up until 6 months after ROSC

Biospecimen

Retention: SAMPLES WITHOUT DNA

Blood was collected 10-14 days, 3 months, and 6 months after ROSC by venipuncture, and the obtained blood was collected in an SST bottle without anticoagulant and centrifuged (3,000 rpm, 10 minutes or more) within 60 minutes. Divided into tubes, and pre-treated tubes are stored frozen at -70 degrees.
