Foundation:

The epidemiological behavior of cerebral infarction leads to the need for studies aimed at characterizing the prognosis of patients, and establishing factors correlated with evolution, summarized in models that allow directing treatment actions towards these determinants.

Objective:

to describe the main prognostic, clinical and epidemiological factors in patients with total cerebral infarction of anterior circulation.

Methods:

descriptive study, in adult patients (N=35) with total cerebral infarction of previous circulation, admitted to the Stroke Unit, of the Arnaldo Milián Castro Hospital, from March 2017 to March 2018. Clinical-demographic variables were analyzed and related to ischemic injury, and were associated with the overall prognosis of patients. The Independence Test based on the Chi-square Distribution and the Student t-test were applied.

Results:

81.82 % of patients between 75 and 85 years evolved unfavorably, and the probability of a worse prognosis in older patients was higher (X2 = 10.59; p = 0.007). In those who presented higher levels of mean blood pressure and longer time with oxygen saturation less than 90 % during sleep, the probability of an unfavorable final prognosis was higher (p =0.000). None of the factors associated with ischemic injury was significantly related to the prognosis (p>0.05).

Conclusion:

age, average mean blood pressure, and oxygen saturation time of less than 90 % during sleep in the acute phase of stroke are associated with a higher probability of presenting an unfavorable overall prognosis.
