When amiodarone-induced thyroiditis meets cardiomyopathy with excessive trabeculation: a case report.

Introduction: Amiodarone is a potent antiarrhythmic medication used to treat life-threatening ventricular arrhythmias; however, its well-established adverse effect is a thyroid disorder. Amiodarone-induced thyroiditis (AIT), a clinical entity involving two types with different etiopathology and treatment approaches, may occur at the beginning or even several years after amiodarone treatment discontinuation. The toxicity profile of amiodarone becomes especially important in young patients with lifelong cardiac disorders, which are often refractory to other antiarrhythmic drugs.

Study of vitamin D receptor gene polymorphisms in a cohort of myocardial infarction patients with coronary artery disease.

Background: Vitamin D deficiency is associated with cardiovascular diseases, including coronary artery diseases (CAD). As vitamin D manifests its biological function through its vitamin D receptor (VDR), VDR gene polymorphisms potentially affect VDR functionality and vitamin D activity. Therefore, the objective of this study was to analyze three well-studied VDR gene polymorphisms-Fok1 (rs2228570), BsmI (rs1544410) and Taq1 (rs731236)-in a cohort of CAD patients after acute myocardial infarction.

Vitamin D-binding protein (rs4588) T/T genotype is associated with anteroseptal myocardial infarction in coronary artery disease patients.

Background: Cardiovascular diseases (CVD) are among leading causes of death worldwide and amongst CVD, coronary artery disease (CAD) accounts for almost half of all cardiovascular deaths as the most common cause of death in the developed world. Vitamin D and the vitamin D-binding protein (VDBP) have been studied as possible CAD pathogenesis factors but literature data provide opposing evidence on their role in CAD. Herein we aimed to present novel evidence on the association of two VDBP polymorphisms (rs4588) and (rs7041) with CAD in patients after acute myocardial infarction and study possible correlations of these polymorphisms with 25-hydroxyvitamin D [25(OH)D] serum levels.

Correlation between immunological-inflammatory markers and endothelial disfunction in the early stage of coronary heart disease.

Classical risk factors for endothelial dysfunction (ED), such as age, gender, total cholesterol, high-density lipoprotein cholesterol, systolic blood pressure, and smoking history are utilised for the Framingham score and Systemic Coronary Risk Estimation (SCORE) for evaluation of the 10-year cardiovascular risk in routine practice. Nonetheless, pro-inflammatory mediators are deeply involved in the initiation and the progression of ED and coronary artery disease (CAD), and act additionally or independently of metabolic factors before clinical manifestations of the disease appear. C-reactive protein, a marker of intimal thickening of the myeloid-related protein 8/14 heterodimer, monocyte chemotactic protein 1, interleukin-15, the cytotoxic mediator, granulysin, and the matrix metalloproteinase 9 could be valuable, single, fast, and non-invasive laboratory tools for ED deterioration degree assessment.
