Relationships between related gene polymorphisms and antihypertensive effect of irbesartan in the senile hypertensive patients
Objective To investigate the effects of related gene polymorphisms on the antihypertensive effect of irbesartan in the senile hypertensive patients. Methods 150 senile hypertensive patients with mild or moderate hypertension were treated with irbesartan for 8 weeks. At the same time, the ACE gene I/D polymorphism, AGT gene M235T polymorphism and AT1R gene A1166C polymorphism were detected by PCR-RFLP. Results Compared with senile hypertensive patients with ACE II genotype, patients with ID and DD genotype showed a greater reduction in blood pressure after taking the medication and the difference was statistically significant (P<0.05). However, the AGT gene and AT1R gene polymorphisms were not related to the the reduction of blood pressure. Conclusions ACE gene I/D polymorphism was related to the reduction of blood pressure after taking irbesartan in the senile hypertensive patients.
