Résumé
The association between subclinical thyroid dysfunction and cardiovascular outcomes has been recently clarified with the publication of three individual participant data (IPD) analyses from the Thyroid Studies Collaboration. We identified original cohort studies with a systematic review and pooled individual data from over 70'000 participants to obtain a more precise estimate of the risks of cardiovascular outcomes associated with subclinical thyroid dysfunction. Subclinical hypothyroidism and subclinical hyperthyroidism, defined as normal thyroxine (FT4) levels with increased or decreased Thyroid-Stimulating Hormones (TSH or thyrotropin) respectively, are associated with increased risk of cardiovascular outcomes compared to euthyroid state, particularly in those with a more pronounced thyroid dysfunction. Specifically, subclinical hypothyroidism is associated with an increased risk of coronary heart disease (CHD) events, CHD mortality and heart failure (HF) events in individuals with higher TSH levels, particularly in those with TSH levels ≥10.0 mIU/L. Conversely, subclinical hyperthyroidism is associated with an increased risk of total mortality, CHD mortality, HF and atrial fibrillation, particularly in those with suppressed TSH levels
