The multicellular organismal process by which the heart decreases in volume in a characteristic way to propel blood through the body. The process by which the secretion of epinephrine into the bloodstream or released from nerve endings modulates the force of heart muscle contraction. Any process that modulates the extent of heart contraction, changing the force with which blood is propelled. Any process that increases the force with which the cardiac muscles of the heart pump blood through the circulatory system as a result of the presence of epinephrine or norepinephrine in the bloodstream or released from the nerve endings. Any process that modulates the frequency, rate or extent of heart contraction. Heart contraction is the process by which the heart decreases in volume in a characteristic way to propel blood through the body. Any process that activates or increases the frequency, rate or extent of an organismal process, any of the processes pertinent to the function of an organism above the cellular level; includes the integrated processes of tissues and organs. The regulation of the force of heart muscle contraction mediated by chemical signaling, hormonal, autocrine or paracrine. Any process which increases the force of heart muscle contraction mediated by chemical signaling, hormonal, autocrine or paracrine. The process by which the secretion of norepinephrine into the bloodstream or released from nerve endings modulates the force of heart musclecontraction. Any process that activates or increases the frequency, rate or extent of heart contraction.
