verify Relationship of noninvasive assessment of central arterial blood pressure with 10 years Atherosclerotic Cardiovascular disease (ASCVD) in Subclinical hypothyroidism

Subclinical hypothyroidism (SCH), characterized by elevated thyrotropin (TSH) levels with normal free thyroxine (T3,T4) concentrations, is a prevalent disorder affecting approximately 10% of the adult population. It has been increasingly recognized for its potential impact on cardiovascular health. A 10-year follow-up study highlighted a significant association between elevated serum TSH levels and increased cardiovascular (CV) risk, independent of conventional risk factors. And it demonstrated its association with hypercholesterolemia and atherosclerosis as the leading risk of CVD. Moreover, in a recent meta-analysis, subclinical hypothyroidism was shown actually be correlated with an increased risk of CVD and mortality. Monitoring thyroid function underscores the potential importance of cardiovascular (CV) risk assessment, for patients with subclinical hypothyroidism (SCH). Incorporating thyroid function tests, such as TSH and free thyroxine (FT4) levels, alongside non-invasive central arterial blood pressure monitoring, provides a comprehensive understanding of a patient's CV risk. This integrated approach enables early identification and targeted interventions, ultimately improving patient outcomes and reducing the incidence of CVD among those with SCH. One of the earliest functional changes underlying ASCVD is Arterial stiffening it reflects a variety of pathologies, including atherosclerosis. As an important determinant of cardiovascular health, arterial stiffness can contribute to increased blood pressure and reduces vessels' capacity to buffer the pulsatile flow when the heart contracts, which are significant risk factors for predicting ASCVD. For continuous non-invasive central arterial blood pressure monitoring, the auscultatory method or The Oscillometric technique can be used. These methods provide valuable insights into the health of the central arteries, which are crucial in understanding the cardiovascular risk profile of patients with SCH.
