Abstract: The aim of this study was to explore the association between angiotensin-converting enzyme (ACE) gene insertion/deletion polymorphism in the 16th intron and the occurrence of left ventricular hypertrophy (LVH) in hypertensive individuals.This study included 269 patients with hypertension from Dushu Lake Hospital Affiliated to Soochow University who underwent echocardiographic examinations. Among them, 55 patients had hypertension combined with LVH, while 214 patients with hypertension did not have LVH, serving as the case and control groups, respectively. Polymerase chain reaction-restriction fragment length polymorphism was used to perform genetic testing for hypertension in all 269 patients. The Hardy-Weinberg equilibrium test was used to assess genetic equilibrium. The differences in genotype frequencies between the case and control groups were analyzed using the chi-square test. All statistical analyses were performed using SPSS software (version 27.0.1), with statistical significance set at P < 0.05.Genotype distribution in the case and control groups conformed to the Hardy-Weinberg equilibrium (P > 0.05). There was a significant difference in genotype distribution between the case and control groups.Conclusion: ACE gene polymorphism is associated with an increased risk of hypertension combined with LVH.
