This document presents the results of a study on the relationship between thyroid hormone status and blood pressure. The study divided participants into three groups: hypothyroid patients, hyperthyroid patients, and healthy controls. The study found that resting systolic blood pressure was significantly higher in hyperthyroid patients compared to the other groups. The study suggests that elevated levels of thyroid hormone can increase cardiac output, leading to higher blood pressure. The study concludes that maintaining normal thyroid hormone levels is important for preventing the negative effects of elevated blood pressure. [Extracted from the article]

Introduction: Hypothyroid or Hyperthyroid state affects all the physiological systems including cardiovascular system, central nervous system, digestive system, blood, etc. Despite increasing knowledge of thyroid physiology and better means for investigation of thyroid functions, we still are at preliminary stage of understanding the pathophysiology of these disorders Objectives: The present study was carried out to compare body T3, T4 and TSH levels in newly diagnosed patients of hypothyroidism, hyperthyroidism and age and gender matched euthyroid subjects Materials and methods: The present study was carried out in 90 female subjects in the age group of 30 to 45. Diagnosis of hypothyroidism and hyperthyroidism was based on both clinical and biochemical criteria. Subjects were divided in euthyroid, hypothyroid and hyperthyroid groups with each group containing 30 subjects. T3, T4 & TSH levels were measured in all the groups. Results: Hyperthyroid group had significantly higher T3 and T4 levels as compared to euthyroid and hypothyroid groups. Hypothyroid group had significantly higher TSH as compared to euthyroid and hyperthyroid groups. Conclusion: T3 and T4 levels are significantly higher in hyperthyroidism and they are significantly lower in Hypothyroidism as compared to euthyroid premenopausal women. TSH levels are significantly higher in hypothyroid subjects, while TSH levels are significantly lower in hyperthyroid subjects. Regular monitoring of T3, T4 and TSH especially in women is recommended. [ABSTRACT FROM AUTHOR]
