The multicellular organismal process by which the heart decreases in volume in a characteristic way to propel blood through the body. Any process that modulates the extent of heart contraction, changing the force with which blood is propelled. Any process that modulates the frequency, rate or extent of a system process, a multicellular organismal process carried out by any of the organs or tissues in an organ system. The regulation of the force of heart muscle contraction mediated by chemical signaling, hormonal, autocrine or paracrine. 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 modulates the frequency, rate or extent of any biological process, quality or function. Any process that modulates the frequency, rate or extent of a biological quality. A biological quality is a measurable attribute of an organism or part of an organism, such as size, mass, shape, color, etc.
