MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The association of thyroid function with coronary heart disease is well–established but not much was known about the association of thyroid function with sudden cardiac death. We conducted the study with the hypothesis that thyroid hormone levels affect cardiovascular risk factors and therefore could also affect the risk of sudden cardiac death (SCD). We were surprised to see that when we control our analyses for these cardiovascular risk factors, the association of high and high-normal thyroid function with SCD remained similar, suggesting that other pathways could play a role. Thyroid hormone has different effects on the cardiovascular systems and future studies should identify which pathway could be responsible for the increased risk of sudden cardiac death with higher thyroid hormone levels. This could lead to better assessment of individual risk and identify possible prevention targets.
