[In-hospital mortality from cerebrovascular accidents in an urban center in Argentina].

Abstract

Introduction: In-hospital mortality is influenced by various factors. Despite the trend toward decreased mortality from acute stroke in the Northern Hemisphere, reports in our region show variable figures. This study reports in-hospital mortality for the second time from a medical center in Ciudad de Buenos Aires. Factors associated with mortality in these patients were also identified.

Materials and methods: A retrospective study was conducted using data from the FLENI Stroke Database between 2010 and 2019, analyzing clinical characteristics, risk factors, complications, and mortality of hospitalized patients. Univariable and multivariable statistical analyses were used to identify risk factors associated with in-hospital mortality.

Results: Data from 1645 patients were analysed, of which 1476 (90%) had ischemic stroke, 95 (6%) had hemorrhagic stroke, and 74 (4%) had aneurysmal subarachnoid hemorrhage (aSAH). There were 45 in-hospital deaths (2%): 26 deaths (1%) from ischemic stroke, 11 deaths (11%) from hemorrhagic stroke, and 8 deaths (10%) from aSAH. Factors associated with mortality include advanced age, low hemoglobin levels at admission, higher scores on the NIHSS scale at admission, and a history of diabetes mellitus.

Discussion: In-hospital mortality from stroke remains low in our institution, with differences between ischemic and hemorrhagic stroke. Factors such as stroke severity, hemoglobin levels, and a history of diabetes mellitus are independent predictors of mortality.
