Relationship of thyroid dysfunction with cardiovascular diseases: updated review on heart failure progression.

Relationship of thyroid dysfunction with cardiovascular diseases: updated review on heart failure progression. Hormones (Athens). 2020 Jun 02;: Authors: Abdel-Moneim A, Gaber AM, Gouda S, Osama A, Othman SI, Allam G Abstract Heart disease remains the leading cause of death globally. Heart failure (HF) is a clinical syndrome that results from impairment of the ability of the ventricle to fill with or eject blood. Over the past two decades, accumulated evidence has revealed the contribution of thyroid hormones to cardiovascular (CV) events, exerting their action through genomic and non-genomic pathways within the cardiomyocytes. The pivotal role of thyroid hormones in maintaining cardiac homeostasis has been observed in previous investigations which suggest that the CV system is adversely impacted by fluctuations in thyroid hormone levels, such as those that occur in hypothyroidism, hyperthyroidism, and low triiodothyronine syndrome (LT3S). Thyroid dysfunction has direct effects on myocardial contractility, systolic and diastolic blood pressure, heart mass, heart rate, ejection fraction, and heart output, which may ultimately lead to HF. Recent clinical data have shown that thyroid hormone replacement therapy for hypothyroid patients appears to provide the potential for reducing CV events. Therefore, this review aims to address the impact of thyroid hormone dysfunction on pathophysiological mechanisms contributing to the development and progression of HF. ...

Conclusion: The prevalence of functional deficit was high among children and adolescents with congenital heart disease after cardiac surgery. Higher surgical risk, longer duration of invasive mechanical ventilation, longer intensive care unit stay and younger age were correlated with worse functional status.

Conclusion: The risk of severe maternal cardiac complications during pregnancy in women with congenital heart disease is low. In this largest analysis to date with a focus on parity in 307 women, the risk classification predicts the maternal outcome more than parity per se. If the first pregnancy is uneventful, the OR is 5.5 for an uneventful second pregnancy if CARPREG I and mWHO scores remain unchanged.Cardiology

"Is there any reason to treat subclinical hypo and hyperthyroidism?" Ann Endocrinol (Paris). 2020 Mar 04;: Authors: Biondi B Abstract Subclinical thyroid disease represents an early stage of thyroid dysfunction, which is usually asymptomatic and biochemically defined; its diagnosis can be performed thanks to the high sensitivity of the hypothalamic-pituitary-thyroid axis. The approach to this disorder requires correct diagnosis, clinical assessment and treatment. Cardiovascular diseases (e.g. atrial fibrillation, heart failure, and coronary heart disease), bone loss and fractures, and dement...

Authors: Sun J, Yao L, Fang Y, Yang R, Chen Y, Yang K, Tian L Abstract BACKGROUND: Evidence on the association between subclinical thyroid dysfunction and the risk of cardiovascular outcomes are conflicting. METHODS AND RESULTS: PubMed, EMbase, Web of Science, Cochrane Library, and China Biology Medicine (CBM) databases were searched from inception to July 10, 2016. A total of 16 studies were included for meta-analysis. We found that subclinical hypothyroidism was not correlated with coronary heart disease (CHD) (RR = 1.17; 95% CI, 0.91-1.52), total mortality (RR = 1.02; 95% CI, 0.93...

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 incre...
