Differences of Lipid Profile Among Ischemic and Hemorrhagic Stroke Patients in a Tertiary Hospital in Riyadh, Saudi Arabia: A Retrospective Cohort Study.

Abstract

ObjectiveThis study aims to compare the serum lipid profiles of patients with ischaemic and hemorrhagic strokes.Study designThis was a retrospective, comparative study.Place and duration of the studyThe study was conducted at Military Hospital, Riyadh, from January 1, 2018, to December 31, 2020.MethodologyPatients with a diagnosis of stroke who presented to the emergency department and was confirmed to have ischemic or hemorrhagic strokes by computed tomography (CT) from January 1, 2018, to December 31, 2020. This study was based on data extracted from an electronic hospital information system (BESTCare) of patients presenting to King Abdulaziz Medical City, National Guard Health Affairs, which is a tertiary medical center in Riyadh, Saudi Arabia. Patients who lack lipid profile reading within six months before the incident or had a traumatic hemorrhagic stroke were excluded from the study. All these variables were included in the study: age, gender, height, weight, date of the incident, date of last lipid profile results, type of stroke, comorbidities, on a statin or not, and lipid profile including (high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol, and triglycerides). Microsoft Excel 2019 (Microsoft Corporation, Redmond, WA) was used for data entry and data cleaning, and Statistical Package for the Social Sciences (SPSS) version 23 (IBM Corp., Armonk, NY) was used for data analysis and visualization of the results.ResultsThe mean age of presentation of stroke was 68±13, 59% of patients were males, and 41% were females. BMI ranged from 30±8. Obesity (BMI 30 or above) was predominant in both stroke subtypes. Among all patient comorbidities, hypertension was the most predominant. Diabetes was present in 71% of the population. Of the participants in this study, 114 had ischemic stroke and 87 had a hemorrhagic type. A comparison of the serum lipid profile of two categories of strokes showed no statistical significance in serum values of total cholesterol, triglycerides, and LDL-C in ischemic and hemorrhagic stroke patients.
