Subclinical thyroid dysfunction and cardiovascular diseases: 2016 update
AbstractSubclinical thyroid dysfunction comprises subclinical hypothyroidism (SHypo), defined as elevated thyroid-stimulating hormone (TSH) by normal free thyroxine (FT4), and subclinical hyperthyroidism (SHyper) with decreased or undetectable TSH and normal FT4. Up to 10% of the elderly have SHypo, which is usually asymptomatic. Individual participant data (IPD) analyses of prospective cohort studies from the international Thyroid Studies Collaboration show that SHypo is associated with increased coronary heart disease (CHD) mortality [hazard ratio (HR) 1,58 for TSH ≥ 10 mIU/L, 95% CI 1.10–2.27), as well as increased ...

Antihypertensive treatment and risk of atrial fibrillation: a nationwide study
Conclusion Use of ACEis and ARBs compared with β-blockers and diuretics associates with a reduced risk of atrial fibrillation, but not stroke, within the limitations of a retrospective study reporting associations. This suggests that controlling activation of the renin-angiotensin system in addition to controlling blood pressure is associated with a reduced risk of atrial fibrillation.
