AGTR1 A1166C gene polymorphism is associated with the effectiveness of valsartan monotherapy in Chinese patients with essential hypertension: A retrospective analysis

Objective: To investigate whether angiotensin II type 1 receptor (AGTR1 A1166C) gene polymorphism was associated with the effectiveness of valsartan monotherapy in Chinese patients with essential hypertension. Methods: This retrospective analysis included 198 patients (⩾18 years of age) who received valsartan monotherapy (80 mg/day) for newly developed essential hypertension at the authors’ center between January 1, 2020 and December 31, 2023. Genotyping for AGTR1 A1166C gene polymorphism was done by polymerase chain reaction (PCR)-melting curve analysis of genomic DNA from peripheral blood samples. A dominant genetic model for AGTR1 A1166C (AA genotype versus AC + CC genotype) was used. Multivariate regression analysis of baseline variables and AGTR1 polymorphism was conducted to identify predictors of target blood pressure attainment (
