Prediction of Delayed Cognitive Impairment in Cardiac Arrest Survivors With Good Neurological Outcomes

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?
