ABSTRACT
BACKGROUND: Vascular disease remains the prime contributor to the pathogenesis of stroke, but dyslipidemia has not been clearly established as a risk factor for stroke the same way it has been for coronary artery disease. There is no case-controlled study on the contribution of serum lipids to stroke in Nigerians. This study aimed at assessing the possibility of serum lipids as risk factor for stroke in Nigerian patients. METHOD: The demography, blood pressure, fasting plasma glucose and fasting serum lipids of 87 consecutive patients with first-ever stroke managed at the University of Benin teaching hospital between January and December 2005 were analyzed and compared with those of age- and sex-matched controls. RESULTS: Eighty-seven stroke patients (55 males and 32 females; mean age 61.25 +/- 14.77 years) were compared with age- and sex-matched controls. Ischemic stroke constituted 64.37%, while the rest had hemorrhagic stroke. There were no significant differences in the serum cholesterol, HDL-C and LDL-C levels of stroke patients and controls (p > 0.05), but the serum triglyceride level was higher among the stroke patients (p < 0.001) with a significant relative risk (RR = 1.77; p < 0.01). CONCLUSION: In this cross-sectional case-control study, there is no significant difference in the serum lipids of Nigerian patients with stroke with the exception of serum triglyceride, which seems to confer significant stroke risk.
