Hypertrophic cardiomyopathy (HCM) is a heart muscle disorder and is the most common form of Mendelianinherited heart disease, affecting approximately 0.2% of the global population. In adults the disease is often inherited as an autosomal dominant trait caused by mutations, mainly in one of the 23 cardiac sarcomere protein genes.

Dilated cardiomyopathy (DCM) is chronic heart muscle disease characterized by progressive ventricular enlargement and contractile dysfunction involving either left or both ventricles. It is considered one of the leading causes of heart failure with reduced ejection fraction (HFrEF) worldwide

The presentation of thyroid disease is on a spectrum with clinical presentations and disease severity ranging from subclinical to critical. The principal function of the thyroid gland is to produce T3 (triiodothyronine) and T4 (thyroxine). The hypothalamus and pituitary glands release thyrotropin releasing hormone (TRH) and thyroid stimulating hormone (TSH) respectively, and this stimulates the release of T3 and T4 directly from the thyroid gland.

A 59-year-old man presents to the hospital following a syncopal episode after a low-speed car accident without visible injuries. He was diagnosed with stress cardiomyopathy and severe triple-vessel coronary artery disease. The case was complicated by complete heart block that culminated in refractory cardiogenic shock. Literature and current approach are reviewed.

The incidence and prevalence of papillary thyroid cancer (PTC) are increasing worldwide and it is the 5th most common endocrine cancer in females.
