RESUMEN

Cardiac arrest survivors develop a variety of neuropsychological impairments and neuroanatomical lesions. The goal of this study is to evaluate if brain voxel-based morphometry and lesional Magnetic Resonance Imaging (MRI) analyses performed in the acute phase of an Out-of-Hospital Cardiac Arrest (OHCA) can be sensitive enough to predict the persistence of neuropsychological disorders beyond 3 months. Survivors underwent a prospective brain MRI during the first month after an OHCA and performed neuropsychological assessments at 1 and 3 months. According to the second neuropsychological assessment, survivors were separated into two subgroups, a deficit subgroup with persistent memory, executive functions, attention and/or praxis disorders (n = 11) and a preserved subgroup, disorders free (n = 14). Brain vascular lesion images were investigated, and volumetric changes were compared with healthy controls. Correlations were discussed between brain MRI results, OHCA data and the second neuropsychological assessment. Analyses of acute ischemic lesions did not reveal significant differences between the two subgroups (p = .35), and correlations with cognitive impairments could not be assessed. voxel-based morphometry analyses revealed a global cerebral volume reduction for the two subgroups and a clear decrease of the right thalamic volume for the deficit subgroup. It was associated with a cognitive dysexecutive syndrome represented by four executive indexes according to the 'Groupe de Réflexion pour l'Evaluation des Fonctions EXécutives' criteria. The right thalamus atrophy seems to be more predictive than the vascular lesions and more specific than a global cerebral volume reduction of post-OHCA neuropsychological executive disorders.

RESUMEN

Extracorporeal cardiopulmonary resuscitation (ECPR) can be associated with increased survival and neurologic benefits in selected patients with out-of-hospital cardiac arrest (OHCA). However, there remains insufficient evidence to recommend the routine use of ECPR for patients with OHCA. A novel integrated trauma workflow concept that utilizes a sliding computed tomography (CT) scanner and interventional radiology (IR) system, named a hybrid emergency room system (HERS), allowing emergency therapeutic interventions and CT examination without relocating trauma patients, has recently evolved in Japan. HERS can drastically shorten the ECPR implementation time and more quickly facilitate definitive interventions than the conventional advanced cardiovascular life support workflow. Herein, we discuss our novel workflow concept using HERS on ECPR for patients with OHCA.

RESUMEN

BACKGROUND: Postresuscitation myocardial dysfunction (PRMD) can develop after successful resuscitation from cardiac arrest. However, echocardiographic patterns of PRMD remain unknown. This study aimed to investigate PRMD manifestations with serial echocardiography during the post-cardiac arrest period. METHODS: We enrolled non-traumatic out-of-hospital cardiac arrest patients older than 19 years who underwent successful cardiopulmonary resuscitation (CPR). We excluded patients with myocardial infarction or pre-existing cardiac disease, including heart failure or myocardial disease. Transthoracic echocardiography (TTE) was performed within 24 h, between 24 and 48 h, and between 72 and 96 h after restoration of spontaneous circulation (ROSC). RESULTS: Of 280 patients, 138 (93 men) were analysed. PRMD was observed in 45 patients (33%), including global dysfunction in 28 patients (20%), regional wall motion abnormalities (RWMA) in 10 (7%), and Takotsubo pattern in 7 (5%). There were no differences in clinical characteristics, laboratory findings, or hospital mortality according to PRMD pattern. Global left ventricular (LV) systolic function gradually improved with time and had recovered to normal by Day 3 in all patients except one with the Takotsubo pattern, which remained on follow-up echocardiography two weeks after ROSC. CONCLUSIONS: PRMD occurs in about one-third of patients resuscitated from cardiac arrest. Echocardiographic patterns of post-cardiac arrest LV dysfunction include global hypokinesia, regional wall motion abnormalities, and Takotsubo pattern.
