Incidence, risk factors, clinical presentation, and outcomes of hemorrhagic transformation in patients with ischemic stroke admitted to a tertiary hospital in kingdom of saudi arabia

Abstract

Objectives: To describe the incidence rate, clinical presentation, relevant risk factors, and outcome of hemorrhagic transformation (HT) among ischemic stroke patients. Methods: This retrospective study analyzed HT in patients with ischemic stroke admitted to King Abdullah Medical City from August 2011 to April 2019. Data were analyzed using SPSS. Patients characteristics, procedures, treatments, and outcomes were reported. Results: There were 504 ischemic stroke patients. The HT was detected in 38 patients (8%). The median age was 66.5 (54.3-77.5) years, and 24 (63%) were males. HT was classified as hemorrhagic infarction (HI) in 22 patients (58%) while 16 patients (42%) were parenchymal hematoma (PH). The most common risk factors noted were: hypertension (74%), diabetes mellitus (DM) (66%), hyperlipidemia (63%) and ischemic heart disease (IHD) (61%). Nine patients (23.6%) developed HT after receiving thrombolytic therapy. Only one patient (3%) died of HT patients. Conclusion: HT accounted for (8%) of all ischemic stroke patients. Old age, DM, hypertension, and hyperlipidemia are frequently encountered with stroke patients who developed HT. Follow up CT brain could be of value and could identify HT early to get better outcomes.
