In pursuit of the causes of cardiac hypertrophy

Specific genes are responsible for determining cell growth and differentiation during the early stages of cardiac development. Reactivation of these genes later in life can lead to an abnormal thickening of the heart muscle. ...

Can cancer itself damage the heart?

Research presented today at EuroEcho-Imaging 2015 raises the possibility that cancer itself may damage heart muscle irrespective of exposure to cancer drug therapies. Researchers from the UK's first dedicated cardio-oncology ...

Cardiac muscle

Cardiac muscle is a type of involuntary striated muscle found in the walls of the heart, specifically the myocardium. Cardiac muscle cells are known as cardiac myocytes (or cardiomyocytes). Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. The cells that comprise cardiac muscle are sometimes seen as intermediate between these two other types in terms of appearance, structure, metabolism, excitation-coupling and mechanism of contraction. Cardiac muscle shares similarities with skeletal muscle with regard to its striated appearance and contraction, with both differing significantly from smooth muscle cells.

Coordinated contraction of cardiac muscle cells in the heart propel blood from the atria and ventricles to the blood vessels of the circulatory system. Cardiac muscle cells, like all tissues in the body, rely on an ample blood supply to deliver oxygen and nutrients and to remove waste products such as carbon dioxide. The coronary arteries fulfill this function.
