    AbstractThe prognostic role of the angiotensin-converting enzyme (ACE) insertion/deletion (I/D) genetic polymorphism in patients with acute myocardial infarction (AMI) is controversial and inconsistent across various study populations. This study evaluated the predictive validity of the ACE I/D variant based on 12-month all-cause mortality in Vietnamese patients after AMI. This was an observational, prospective study conducted among AMI patients at Cho Ray Hospital between January 2020 and September 2021. All participants were identified for ACE I/D polymorphism using the polymerase chain reaction method, with follow-up on survival status at 12 months from the date of admission. The proportions of II, ID, and DD genotypes of the ACE I/D variant were 49.5%, 35.9%, and 14.6%, respectively. All-cause mortality after 12 months occurred in 58 cases (10.6%). The ACE I/D polymorphism did not affect all-cause mortality in the dominant (P = .196), recessive (P = .827), homozygous (P = .515), and heterozygous (P = .184) models. A subgroup analysis by usage status of angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker (ACEI/ARB) showed that in the non-ACEI/ARB group, patients with the DD genotype had a lower cumulative survival probability than patients with the II/ID genotypes (hazard ratio [HR] = 3.97, 95% confidence interval [CI]: 1.21-13.04; P = .023). Among patients with Global Registry of Acute Coronary Events (GRACE) scores below the median (153.5 points), those with DD genotype had a higher risk of mortality than those with the II/ID genotypes (HR = 3.35, 95% CI: 1.01-11.11; P = .049). The ACE I/D genetic polymorphism was found not to be associated with 12-month all-cause mortality in Vietnamese patients with AMI. However, it was associated with mortality in patients who did not use ACEI/ARB and also whose GRACE scores were below 153.5 points.Copyright © 2023 the Author(s).
