How is LAD angina differnt from RCA angina ?
Can we localise the “Angina related artery ” from the the type of chest pain ?
Patients with stable angia many times have multivessel CAD. There has been some correlation with radiation of anginal pain and the culprit artery.If the angina spreads to jaw or neck it is possibleit might indicate RCA(RIGHT coronary angina) but rarely it indicates LAD/LCX lesions. if the angina radiates to left shoulder it virtually ruels out a RCA disease

good evening sir,
nice article. After reading your article i have gone through few of articles in net on neurocardiology. This I have seen at one site and iam just pasting the same here hoping this wil help.
“The heart is innervated by two groups of sensory neurons. The first group are in the nodose ganglia and they project to the heart via the vagus. The second group are present in the thoracic dorsal root ganglia and project via the cardiac nerves to the heart. This project would identify the terminals of both these groups of neurons in the heart, using anterograde tracing techniques. The goal would then be to identify subgroups of the sensory neurons and relate each group tp specific targets within the heart. By this means, it should be possible to identify the function or sensory modality of each subtype of sensory neuron. An extension of this project would be to examine cardiac sensory neurons in aged animals, as there is evidence that some types of sensory neurons are lost during aging, leading to “silent” heart attacks”.
