Abstract

Abstract : Aims: We aimed to analyze genetic polymorphism of estrogen receptor (ESR) 1 and ESR2 in a series of postmenopausal women with Takotsubo syndrome (TS). Methods: In total, 81 consecutive white women were prospectively enrolled: 22 with TS (TS group; mean age 71.2 ± 9.8 years), 22 with acute myocardial infarction (MI group; mean age 73.2 ± 8 years), and 37 asymptomatic healthy controls (CTRL group; mean age 69 ± 4.2 years). Genotyping of ESR1 −397C>T (rs2234693) and −351A>G (rs9340799) and ESR2 −1839G>T (rs 1271572) and 1082G>A (rs1256049) genetic variants was performed. We estimated the odds ratio (OR) between the genotype of each examined locus with the occurrence of TS or MI. Results: The risk of experiencing TS was higher for those study participants carrying the T allele at the rs2234693 locus of the ESR1 gene [OR: 2.0, 95% confidence interval (CI): 0.973–4.11, P = 0.04, TS vs. MI + CTRL; OR: 2.79, 95% CI: 1.17–6.64, P = 0.016, TS vs. MI alone]. Women carrying a T allele at the rs1271572 locus of the ESR2 gene demonstrated an even higher risk (OR: 3.23, 95% CI: 1.55–6.73, P = 0.0019, TS vs. MI + CTRL; OR: 9.13, 95% CI: 2.78–29.9, P = 0.0001, TS vs. MI alone). Conclusion: The study reports preliminary findings suggesting a possible link between ESR polymorphisms and the occurrence of TS. Larger studies are needed to confirm our results.
