SUBARACHNOID HEMORRHAGE, ANEURYSM RUPTURED, ANEURYSM
The original cohort of this study consisted of patients with aSAH who were treated in a French university hospital's neuro-ICU between 2010 and 2015, with the following inclusion criteria: (I) patients with aSAH hospitalized in the neuro-ICU for mechanical ventilation between January 2010 and December 2015; (II) aged ≥18 years, regardless of sex; (III) subarachnoid hemorrhage due to aneurysm rupture confirmed by computed tomography angiography (CTA); (IV) ST-segment elevation myocardial infarction; and (V) informed consent obtained from the patient or family. The exclusion criteria of the original cohort were as follows: (I) patients with medically induced aneurysm rupture, (II) patients lost to follow-up, and (III) patients with loss of essential clinical features (≥1) after admission and before discharge from the hospital.In the current study, we performed a post hoc analysis of the dataset shared by Chalard et al. We have added the following exclusion criteria based on the objectives of the study (loss of information is the primary exclusion criterion): missing location of the responsible aneurysm (Of the 204 patients, 77 were male and 127 were female, and 91 were aged <55 years and 113 were aged ≥55 years; admission World Federation of Neurosurgical Societies (WFNS) grade was III, IV, and V for 19, 81, and 104 patients, respectively, and admission Fisher scores were grades I, II, II, and IV for 1, 4, 37, and 162 patients, respectively.To develop and validate the clinical prognostic model, 204 patients were randomized using R Studio statistical software in a 7 : 3 ratio to the training group (144 patients) and the verification group (60 patients).
