Abstract
Background and Purpose: Cerebral atherosclerosis is the leading cause of mechanical obstruction of blood flow that final event is cerebral infarction. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an inflammatory biomarkers specific for blood vessels, is an important factor predicted extent of atherosclerosis. The study aimed to assess the association between serum Lp-PLA2 concentration with carotid intimamedia thickness (IMT). Materials andMethod: The cross – sectional study, in 37 patients who presented to Department of Cardiology - Hue University Hospital and Hue Central Hospital. Vulnerability asessment of the external carotid artery into the skull through ultrasound by measuring carotid intima-media thickness. Testing serum Lp-PLA2 concentration, lipid profile, blood glucose. Results: Group of patients with thickness of carotid IMT levels of serum Lp-PLA2 was 27.73 IU/ml higher than the group with thickness normal carotid IMT was 14.35 IU/ml; p < 0.05. Total cholesterol, LDL cholestrol, triglycerid and Lp-PLA2 are the factors capable of predict the changes in size IMT; (p <0.05). There is moderate correlation between Lp-PLA2 levels and carotid intima-media thickness (r = 0.47; p < 0.05). Conclusion: Higher Lp-PLA2 levels is significantly associated with carotid intimamedia thickness in patients who have cerebral infarction. Key words: Stroke, atherosclerosis, inflammation, biomarker.
