Context: Cardiovascular outcomes in mild thyroid dysfunction (treatment controversial) and moderate or severe dysfunction (treatment standard) remain uncertain. Objective: To examine cross-sectional and prospective associations of thyroid function with cardiovascular risk factors and events. Design: In the Atherosclerosis Risk in Communities (ARIC) Study, we measured concentrations of thyrotropin (TSH), free thyroxine (FT4), and total triiodothyronine (T3) in stored serum samples originally collected in 1990-92...

SUMMARY: Takotsubo cardiomyopathy (TC) is an atypical, severe but reversible form of acute heart insufficiency. It typically presents with left ventricular failure, transient apical and mid-segments hypokinesis, absence of significant coronary stenosis and new electrographic abnormalities and/or elevation in serum cardiac enzymes. Although TC ('broken heart syndrome') has classically been associated with emotional trauma, evidence suggests that other precipitants might exist, including iatrogenic and thyroid-mediated forms...

BACKGROUND: Whether hypothyroidism is an independent risk factor for cardiovascular events is still disputed. We aimed to assess the association between hypothyroidism and risks of cardiovascular events and mortality. METHODS: We searched PubMed and Embase from inception to 29 February 2016. Cohort studies were included with no restriction of hypothyroid states. Priori main outcomes were ischemic heart disease (IHD), cardiac mortality, cardiovascular mortality, and all-cause mortality...

Chronic myelomonocytic leukaemia (CMML) is a myelodysplastic/myeloproliferative neoplasm affecting the production and differentiation of the monocyte cell lineage. Cardiac surgery in the context of CMML poses challenges that are not routinely encountered. This is the first reported case in the literature of a patient with active CMML undergoing urgent on-pump coronary artery bypass grafting. A 68-year-old Caucasian man with a history of hypertension, hyperlipidaemia, hypothyroidism, and hypercholesterolaemia, who had been diagnosed by the haematologists with CMML a few months earlier but had remained untreated, underwent urgent surgical coronary revascularisation because of postinfarction angina following a non-ST elevation myocardial infarction associated with troponin I rise...

Myocardial and vascular endothelial tissues have receptors for thyroid hormones and are sensitive to changes in the concentrations of circulating thyroid hormones. The importance of thyroid hormones in maintaining cardiovascular homeostasis can be deduced from clinical and experimental data showing that even subtle changes in thyroid hormone concentrations - such as those observed in subclinical hypothyroidism or hyperthyroidism, and low triiodothyronine syndrome - adversely influence the cardiovascular system...

Aging is associated with increased prevalence of cardiovascular disease. Thyroid hormone deficiency during fetal life decreases myocardial tolerance to ischemia-reperfusion (IR) injury in later life. The long-term effects of fetal hypothyroidism (FH) on response to IR injury in aged rats have not been well documented. The aim of this study was therefore to compare the effect of FH on tolerance to IR injury in young and aged male rats and to determine contribution of iNOS (inducible nitric oxide synthase), Bax, and Bcl-2...

Cardiac thyroid-hormone signaling is a critical determinant of cellular metabolism and function in health and disease. A local hypothyroid condition within the failing heart in rodents has been associated with the re-expression of the fetally expressed thyroid-hormone-inactivating enzyme deiodinase type III (Dio3). While this enzyme emerges as a common denominator in the development of heart failure, the mechanism underlying its regulation remains largely unclear. In the present study, we investigated the involvement of microRNAs (miRNAs) in the regulation of Dio3 mRNA expression in the remodeling left ventricle (LV) of the mouse heart following myocardial infarction (MI)...

BACKGROUND: Coronary subclavian steal syndrome (CSSS) is defined as retrograde flow in the internal mammary artery graft, after coronary artery bypass surgery, resulting in anterior wall myocardial ischemia. If undiagnosed, it may lead to significant infarction. Its incidence has been under-reported. CASE REPORT: A 74-year-old woman presented with sudden onset of typical angina, which was associated with dyspnea, nausea, and vomiting. Her medical history was significant for coronary artery disease, with prior coronary artery bypass surgery (CABG), chronic obstructive pulmonary disease (COPD), hypertension, diabetes type 2, dyslipidemia, hypothyroidism, and depression...

BACKGROUND: Patients with rheumatoid arthritis (RA) suffer from co-morbidities that contribute to a shortened lifespan. Inflammation is important for the development of cardiovascular disease, but little is known on its relationship with other co-morbidities. We investigated the role of inflammation for the development of new comorbidities in early RA. METHODS: Since 1995, all patients with early RA in Northern Sweden are included in a prospective study on co-morbidities, with a total of 950 patients being included...

BACKGROUND: Cardiac disease is the most common cause of morbidity and mortality in the United Kingdom. Even minor changes in thyroid hormone concentration may impact adversely on the cardiovascular system. Subclinical hypothyroidism (SCH) after admission for an acute cardiac problem has been associated with an increase in cardiac mortality and overall death. We have designed protocols for a prospective observational study to assess the association of thyroid function at the time of acute myocardial infarction (AMI) with cardiovascular outcomes, and a double-blinded randomised placebo-controlled trial of levothyroxine to evaluate its effect on LV function and vascular health...

REVIEW
Avais Jabbar, Salman Razvi
Subclinical hypothyroidism (SCH) is a common condition seen in up to 10% of adults, mainly women and the elderly. Several prospective longitudinal cohort studies have shown a higher risk of cardiovascular disease in people with SCH but mainly in younger individuals. There are also a number of interventional trials that have shown that treatment of SCH with levo-thyroxine improves cardiovascular risk factors, but there is a dearth of level 1 evidence regarding cardiovascular events. In addition, there is increasing proof concerning the association of abnormal thyroid function at the time of an acute myocardial infarction with adverse cardiovascular outcomes...

A 90-year-old man was transferred to a geriatric evaluation and management (GEM) unit for management of hypoactive delirium following a pneumonia and acute myocardial infarction complicated by septic shock. He was found to have central hypothyroidism and hypoadrenalism leading to the diagnosis of hypopituitarism. Cerebral imaging confirmed this was secondary to a pituitary haemorrhage. This case illustrates the complexity of assessment of delirium and its aetiologies. Hypoactive forms of delirium in particular can be difficult to detect and therefore remain undiagnosed...

BACKGROUND: Heart failure (HF) is associated with increased atrial fibrillation (AF) risk. Accumulating evidence suggests the presence of myocardial tissue hypothyroidism in HF, which may contribute to HF development. In a recent report we demonstrated that hypothyroidism, like hyperthyroidism, leads to increased AF inducibility. The present study was designed to investigate the effect of thyroid hormone (TH) replacement therapy on AF arrhythmogenesis in HF. METHODS AND RESULTS: Myocardial infarction (MI) was produced in rats by means of coronary artery ligation...
