A short-term survival analysis of severe patients with acute vascular event admitted on intensive care unit department

Abstract

The study evaluated the short-term survival during hospitalization period of the patients admitted on the intensive care unit department with an acute vascular event in comparison with other pathologies. We developed a retrospective cohort study with longitudinal design on 178 subjects admitted in an intensive care unit department. The patients were divided according the presence (33 patients) or absence (145 patients) of an acute vascular event (myocardial infarction or stroke). The survival during the hospitalization period was evaluated also considering the presence of diabetes (58 patients) or diabetes with complications (54 patients). The survival was presented as probability to survive during hospitalization period and median survival time. Logrank test was used to compare the groups. Patients with myocardial infarction had the average age of 60.57±7.97 years old, with 100% mortality during the hospitalisation period and a median survival time of 16 days. The patients with stroke were 66.34±14.12 years old with 46.15% survival probability and median survival time of 26 days; respectively patients without vascular event were 65.52±15.81 years old, had a survival probability of 46.89% and a median survival time of 28 days. Considering all the patients with vascular events, survival probability was 36.36%. Diabetes, the presence of arterial hypertension or diabetic complications does not influence significantly the survival in this sample (Logrank test, p>0.05). Survival of patients with acute vascular event is comparable with that of the patients admitted on intensive care unit for other health condition. A poor prognostic was observed for myocardial infarction.
