Sympathetic afferent fibers originate from a visceral organ, course
in the thoracolumbar rami communicantes, have cell bodies located
in dorsal root ganglia, and terminate in the gray matter of the
spinal cord. Sympathetic afferent fibers from the heart transmit
information about noxious stimuli associated with myocardial
ischemia, i. e. angina pectoris. Previous reviews have described
the characteristics of cardiovascular sympathetic afferent fibers
(Bishop et al. 1983; Malliani 1982). This review summarizes that
work and focuses on the neural mechanisms underlying the
complexities of angina pectoris. In order to understand anginal
pain, cells forming the classical pain pathway, the spinothalamic
tract (STn, were chosen for study. These cells were chosen to
address questions about anginal pain because they transmit
nociceptive informa of pain. Antidromic tion to brain regions that
are involved in the perception activation of STT cells provided a
means of identifying cells involved with trans mission of
nociceptive information in anesthetized animals. Other ascending
pathways may also transmit nociceptive information, but many
studies show that the STT plays an important role. Visceral pain is
commonly referred to overlying somatic structures. The pain of
angina pectoris can be sensed over a wide area of the thorax: in
the retrosternal, precordial anterior thoracic, and anterior
cervical regions of the chest; in the left or sometimes even the
right shoulder, arm, wrist, or hand; or in the jaw and teeth
(Harrison and Reeves 1968)."
