[Prognostic factors for mortality due to acute arterial stroke in a North African population].

introductioncerebrovascular accident (stroke) constitutes a major public health problem due to the number of people affected and to its medical social and economic consequences. This study aims to identify poor vital prognostic factors for survival in patients with acute arterial stroke.

methodswe conducted a prospective study of patients with symptoms suggestive of stroke at the two University Hospitals of Sfax, Tunisia over a period of 4 months. Patients were followed-up for a period of 1 month.

resultswe collected data from 200 patients. After one month of follow-up, mortality was 19.9%. Poor prognostic factors were: male sex, consumption of tobacco, a history of stroke, low Glasgow score, high NIHSS, headaches, acute symptomatic epileptic seizures, Babinski's sign, mydriasis, aphasia, combined deviation of the head and the eyes, high PAS, PAD and PAM, hyperthermia, hyperglycaemia, leukocytosis, high concentration of CRP, creatinine, urea and troponin T, haemorrhagic stroke, perilesional oedema, a mass effect, commitment, total middle cerebral artery topography of ischemia, early signs of ischemia, meningeal hemorrhage, ventricular flood, hydrocephalus, the recourse to respiratory support, to anti-edematous treatment and to antihypertensive therapy, hemorrhagic transformation, vascular epilepsy, infectious, metabolic complications, complications of bed sores.

conclusionthe identification of the predictive factors for survival allows for optimisation of therapeutic procedures and better implementation of patient' management. A comparative study will be considered to measure the impact of the corrective measures.
