The purpose of this study was to explore whether and how TSH regulates the expression of SERCA2a in neonatal rat cardiomyocytes. One such protein, cardiac sarcoplasmic reticulum calcium ATPase (SERCA2a), is a crucial for both cardiac contractility and the restoration of cytosolic calcium concentration during relaxation. These abnormalities often stem from changes in calcium homeostasis caused by altered expression or function of calcium transport or binding proteins. Moreover, exposure to slightly elevated TSH levels may, over time, contribute to systolic and diastolic abnormalities in sTH. described how long-term increases in serum TSH concentration contribute to the development of sHT TSH alone negatively impacted cardiac function, independent of HT. Conventional echocardiography and videodensitometric analysis confirmed that myocardial contractility is reduced and both the active and passive phases of diastole are dysregulated in sHT, as indicated by the following: (a) a lower cyclic variation index (CVI) in sHT indicated altered myocardial intrinsic contractility (b) lower systolic strain and strain rate revealed an impairment of myocardial regional deformability (c) an increase in peak A and decrease in peak E mitral flow velocity that resulted in a decline in left ventricular diastolic function. Similarly, sHT is also associated with diastolic dysfunction, characterized by impaired early ventricular filling and slowed myocardial relaxation at rest that becomes more pronounced during exercise. In sHT, the most common cardiac abnormality is an impairment in LV systolic function, characterized by increases in mean aortic acceleration and pre-ejection/ejection time ratio both at rest and during exercise.

Interestingly, we found that the risk of these cardiovascular events is also increased in subclinical hypothyroidism (sHT), which is defined by elevated serum TSH with normal free thyroid hormone levels. Some of these cardiovascular symptoms result from the impact of thyroid hormone on the cardiovascular system. Several studies show that hypothyroidism changes myocardial oxygen consumption, cardiac output, and cardiac contractility, resulting in decreased heart output along with a prolonged isovolumic relaxation phase. Hypothyroidism is characterized by elevated serum thyroid stimulating hormone (TSH) concentrations and reduced concentrations of free T4.
