Abstract:

Hyperhomocysteinemia and abnormal blood lipids are independent risk factors for stroke. However, whether both factors exert a synergistic effect in the onset of stroke remains unclear. The present study is a retrospective analysis of 2 089 cases of stroke and 2 089 control cases of simple inter-vertebral disk protrusion using a paired multivariate logistic regression method. Adjusting for known confounding variables including the patients’ age, gender, smoking status, alcohol consumption status, patient and family medical history, and clinical biochemical indices, elevated homocysteine level was related to the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids showed a 40.9 % increase in the risk for stroke compared to patients with normal homocysteine levels and blood lipids (odds ratio 1.409; 95% confidence interval 1.127–1.761). These results indicate that elevated homocysteine and abnormal blood lipids exert synergistic ef-fects in the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids are predisposed to stroke.
