Cardiac Muscle

Also known as:  Heart Muscle;  Muscle of the Heart;  Myocardial Muscle

Cardiac Muscle is a type of Muscle located in the (Myocardium [middle layer]) of the Heart.  Cardiac Muscle is distinguished from Skeletal Muscle and Smooth Muscle by being thicker than Smooth Muscle and falling under the control of the Autonomic Nervous System.  Histamine H2 Receptors are located in Cardiac Muscle.

Amino Acids

 By normalizing Potassium flow into and out of Cardiac Muscle cells, Taurine may normalize the electrical excitability of the Cell Membranes of Cardiac Muscle and may enhance the contractile strength of the Cardiac Muscle.  Taurine may also modulate the activity of cyclic AMP within the Cardiac Muscle.  ^[1]

Carbohydrates

 Ribose may increase Energy production in Cardiac Muscle.  ^[2]

Hormones

 Supplemental (exogenous) Human Growth Hormone (hGH) may increase Cardiac Muscle strength (in Congestive Heart Failure patients).  ^[3]
