Objectives: The research conducted at the Department of Neurology, University Hospital Center Split aims to determine the proportion of patients with typical intracerebral hemorrhage who have been diagnosed with arterial hypertension. It investigates patient adherence to antihypertensive therapy and analyzes the number of newly diagnosed cases of arterial hypertension during hospitalization. The study compares mortality rates between patients with high adherence wth those who have low adherence. Patients and methods: A retrospective study was conducted at the Department of Neurology, University Hospital Center Split. It included patients hospitalized from March 1st, 2021. to March 1st, 2023. who experienced a typical intracerebral hemorrhage. The data collection process encompassed demographic information, habits, chronic diseases and therapy. The study analyzed four key outcome variables: the presence of arterial hypertension, patient adherence to antihypertensive therapy, newly diagnosed arterial hypertension and a comparison of mortality rates between regular and irregular users of antihypertensive therapy. Results: Out of the 4180 hospitalized patients, 51.03% experienced a stroke. Among those who had a stroke, 10.45% had intracerebral hemorrhage, with 50.67% of them occurring at a typical location. The average age of the patients was 72.99 years. The analysis shows that men had a significantly higher incidence of newly diagnosed hypertension (χ2=7.54; P<0.001). The mortality rate was highest among patients who were not taking hypertension medication (52.94%). Conclusion: The proportion of patients with previously diagnosed hypertension upon hospitalization was higher than the proportion of patients with newly diagnosed hypertension. There was no statistically significant association found between medication adherence and survival, nor between medication adherence and educational level. There was no statistically significant difference in mortality outcomes between patients with pre-diagnosed hypertension who were not taking medication compared to those who were taking medication.
