Hashimoto's thyroiditis (HT) is the most common autoimmune thyroid disease synonymous with hypothyroidism.The link between hypothyroidism and the risk of cardiovascular diseases is of contemporary interest.Studies have indicated the prevalence of metabolic syndrome and endothelial dysfunction in HT patients.HT per se might possess a role in atherosclerosis.Association of HT with dyslipidemia and chronic inflammation leading to endothelial dysfunction has been documented.However, the role of thyroid autoimmunity in promoting cardiovascular diseases remains unclear.Further studies unraveling the causal relationship between HT and cardiovascular disease would provide greater insight into the management of atherogenic complications observed in HT patients.
