This study aims to investigate the impact of ACE (rs4343) and AT1R (rs 5182) genetic polymorphisms on the outcome of acute coronary syndrome (ACS) in patients on captopril. Two hundred and fifty participants with ACS were included in this study (Group 1 (120) participants on captopril 25 mg twice daily and Group 2 (130) participants received no captopril (control study)). Participants were genotyped for ACE (rs4343) and AT1R (rs5182) polymorphisms and the phenotype was determined. ACE polymorphism (rs 4343) GG and GA genotypes are more related to STEMI (OR = 1.7, 1.5 respectively) and NSTEMI (OR = 3, 3.8 respectively), and they were more prone to have Percutaneous Coronary Intervention after ACS attack (OR = 11.6, 14.1 respectively). AT1R (rs 5182) CT genotype is mildly associated with STEMI (OR = 1.1), but also prone to have PCI after ACS attack (OR = 1.6) while TT genotype has a risk to get less improvement (OR = 1.8).

A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.
An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.
A decapeptide that is cleaved from precursor angiotensinogen by RENIN. Angiotensin I has limited biological activity. It is converted to angiotensin II, a potent vasoconstrictor, after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME.
Agents that antagonize ANGIOTENSIN RECEPTORS. Many drugs in this class specifically target the ANGIOTENSIN TYPE 1 RECEPTOR.
An angiotensin receptor subtype that is expressed at high levels in fetal tissues. Many effects of the angiotensin type 2 receptor such as VASODILATION and sodium loss are the opposite of that of the ANGIOTENSIN TYPE 1 RECEPTOR.
