Evaluation for the Relationship Between Normal Serum Level of Thyroid Hormones and Left Ventricular Systolic and Diastolic Dysfunction

Background: Thyroid hormones play an important role in cardiac tissue function. Therefore, it is to understand the relationship between thyroid hormone levels and disorders. Objectives: The present study aimed assess normal serum level of left ventricular systolic diastolic dysfunction. Methods: In this cross sectional descriptive retrospective study, 391 patients were selected. They referred Rajaie Cardiovascular Research Center, Tehran, Iran from 2019 2021. After extracting echocardiographic laboratory data clinical records, parameters affecting dysfunction analyzed using statistical software. Results: mean age was 41 ± 12.8 years. Among them 58.1% all female. Tricuspid regurgitation (TR) severity had a significant with stimulating (TSH) (P = 0.02). End interventricular septum thickness (IVSD) inversely associated thyroxin4 (T4) 0.04). Mitral valve inflow deceleration time (MVDT) correlated thyroxin3 (T3) Left ejection fraction (LVEF) related TSH end right internal diameter (RVIDd) directly 0.05). Conclusions: range can be tricuspid severity, (RVIDd), mitral (MVDT), and. (IVSD). Due high prevalence heart disorders, information on helpful identification timely treatment these
