Background: Hypertension is a prevalent health concern in Indonesia, with a high percentage of patients unresponsive to ACE inhibitor treatment. Methods: This multicenter case-control study investigated the correlation between ACE I/D and captopril effectiveness in Indonesian hypertensive patients. Hypertensive patients were divided into control (n = 69) and case (n = 73) groups. ACE I/D was identified using PCR and electrophoresis.Results: No significant differences in genotype frequencies or allele distribution were observed. The difference of blood pressure reduction among the three genotypes also lacked statistical significance.Conclusion: ACE I/D is not significantly associated with blood pressure reduction following captopril therapy in Indonesian hypertensive patients. These results underscore the limited predictive utility of ACE I/D in managing hypertension with captopril.
