COMPARATIVE ANALYSIS OF LIPID PROFILE IN PATIENTS WITH HEMORRHAGIC VERSUS ISCHEMIC STROKE: A CROSS-SECTIONAL STUDY

Abstract

Objective: Stroke is a major cause of morbidity and mortality worldwide resulting from either an ischemic insult or rupture of a blood vessel in the brain. It not only leads to significant physical disability but also imposes emotional and economic burdens on patients and their families. Assessing the lipid profile in stroke patients is crucial, especially in ischemic stroke, where dyslipidemia plays a key role in atherosclerosis development. Elevated low-density lipoprotein (LDL) and triglycerides (TG) are important modifiable risk factors, and managing these can reduce the incidence and recurrence of strokes. Comprehensive lipid management should be a core component of stroke prevention and treatment strategies.

Methods: This was a cross-sectional study in which 80 adult stroke patients (40 ischemic and 40 hemorrhagic strokes) were included on the basis of a predefined inclusion and exclusion criteria. The diagnosis of stroke was made on the basis of imaging and neurological examination. A comprehensive medical history, physical measurements (including body mass index), and lipid profiles (total cholesterol [TC], LDL, High-density lipoprotein [HDL], and TG) were recorded for all participants. Blood samples were taken after overnight fasting to ensure accuracy. Statistical analysis using SPSS version 21.0 compared lipid levels between the groups. An unpaired t-test and Chi-square test were used, with significance defined as a p<0.05.

Results: There was a significant difference in lipid profiles between ischemic and hemorrhagic stroke patients. Ischemic stroke patients had markedly higher levels of LDL with a mean of 129.84±36.54 mg/dL compared to 106.32±26.68 mg/dL in hemorrhagic stroke patients (p=0.0015). TC levels were also significantly elevated in ischemic stroke patients, averaging 236.22±56.26 mg/dL versus 196.48±46.24 mg/dL in hemorrhagic stroke patients (p=0.0009). Total TG were higher in ischemic stroke patients (158.54±44.68 mg/dL) compared to hemorrhagic stroke patients (128.62±39.16 mg/dL, p=0.0021). HDL levels were slightly lower in ischemic stroke patients (34.54±8.26 mg/dL) compared to hemorrhagic stroke patients (38.12±9.12 mg/dL), although this difference was not statistically significant (p=0.0696).

Conclusion: There were significant differences in lipid profiles between ischemic and hemorrhagic stroke patients. Ischemic stroke patients had higher levels of LDL, TC, and TG, indicating a stronger association with dyslipidemia and atherosclerosis. These findings highlight the importance of aggressive lipid management in ischemic stroke patients to reduce recurrence risk and improve outcomes.
