Abstract

Abstract : The distribution characteristics of Methylenetetrahydrofolate Reductase (MTHFR) gene C677 T polymorphism and its influence on early morning blood pressure in elderly female patients with H-type hypertension are investigated. A total of 220 elderly female patients with hypertension who received diagnosis and treatment in our hospital from March to September 2021 are selected. All patients received serum index detection in our hospital and are grouped according to blood homocysteine (Hcy) level. Patients with Hcy>10 μ mol/L are classified as H-type hypertension and included in H-type hypertension group ( n = 166). Patients with Hcy≤10 μ mol/L are included in the non-H-type hypertension group ( n = 54). Both groups underwent 24-hour ambulatory blood pressure monitoring. Base frequency and allele distribution of MTHFR gene C677 T locus are compared between the two groups, and the relationship between different bases of MTHFR gene C677 T locus and morning blood pressure and Hcy level is analyzed. The risk factors of morning hypertension in patients with H-type hypertension are analyzed by binary logistic regression. Binary logistic regression analysis shows that smoking history, drinking history, high-salt diet, MTHFR gene C677 T genotype, and abnormal 24 h systolic blood pressure are the risk factors for the occurrence of morning hypertension in H-type hypertension patients. The frequency of TT homozygous mutation at the C677 T site of the MTHFR gene is high in patients with H-type hypertension, and the mutation of the C677 T site of the MTHFR gene had an effect on systolic blood pressure and Hcy level.
