摘　　要：Background: High blood pressure is associated with adverse morphological and functional changes in the cardiovascular system, including left ventricular hypertrophy (LVH). Osteoprotegerin (OPG) is a member of the tumor necrosis factor receptor superfamily of cytokines. X-ray repair cross-complementing protein 3 (XRCC3) is involved in the repair pathway for double-strand breaks (DSBs). We assessed the association of osteoprotegerin and XRCC3 gene polymorphisms with the occurrence of left ventricular hypertrophy in hypertensive patients. Patients and methods: The study included 50 hypertensive patients: 25 with LVH (group A) and 25 without LVH (group B). All cases were subjected to complete history taking and clinical examination. ECG and echocardiography were done. LV mass was calculated to detect the presence or absence of LV hypertrophy. DNA was extracted from blood samples, and then, each DNA sample was amplified in PCRs, to detect osteoprotogrin and XRCC3 gene polymorphisms. Results: Mean age in the cases in group A is 63.12 years and in group B was 58.24 years with statistically significant difference between the two groups. The duration of the disease and SBP revealed statistically significant difference between the two groups. The LV mass index and E/A ratio revealed high statistically significant difference between the two groups. OPG sequence revealed no statistically significant difference between the two groups, but XRCC3 sequence revealed statistically significant difference. The age was a risk factor for LVH. Conclusion: Osteoprotogrin and XRCC3 genes polymorphism mutations may be associated with left ventricular hypertrophy in hypertensive patients.Background: High blood pressure is associated with adverse morphological and functional changes in the cardiovascular system, including left ventricular hypertrophy (LVH).
