The Relationship between Apelin and Angiotensin II in Paroxysmal Supraventricular Tachycardia

Background: We aimed to investigate apelin and angiotensin II serum levels in patient whit paroxysmal supraventricular tachycardia. Methods: This was a cross-sectional study on 38 patients with paroxysmal supraventricular tachycardia (PSVT), and 38 age- and sex-matched healthy individuals. Blood samples were taken from these people, and angiotensin II/apelin levels were measured using enzyme-linked immunosorbent assay (ELISA). To analyze the data, descriptive statistics were used. Results: Apelin levels were lower in PSVT group compared to control group; but the difference was not significant (P = 0.302). Angiotensin II levels were significantly lower in PSVT groups compared to controls (P = 0.003). Conclusion: Like similar studies, this study showed that apelin serum levels were lower in PSVT groups, but this difference was not significant. However, mean serum levels of angiotensin II was significantly lower in PSVT groups. This could be due to the consumption of calcium blockers in these patients.
