Heart pain and asthmatic symptoms in the form of dyspnea often occur with osteochondrosis of the thoracic and cervical divisions. The examination does not reveal cardiac pathologies. Painful sensations can be quite long, without causing changes in the myocardium. Cardiac pains are a consequence of inflammation of the nerve roots innervating the organs located in the chest cavity. They have a number of differences from the true pains in the heart:

Pain syndrome can last from several weeks to several months.
The pain periodically intensifies (within 3-4 days), then again subsided.
They can not be stopped with the use of cardiac drugs.
Pain does not lead to anxiety, fear and does not pose a threat to life.
When the spine column is affected, the intensity of sensations increases.
The mechanisms of development of cardiac pain in osteochondrosis are as follows:

Violation of the innervation of the heart. In this case, pain sensations appear as a result of the spread of impulses to the center of sympathetic innervation of the cardiac muscle.
Reflex mechanism. Osteochondrosis leads to disruption of the innervation of the tissues of the shoulder girdle. As a result, receptors in these regions do not receive enough pulses and influence the innervation centers of the heart. From the side of the central nervous system, such impulses begin to be perceived as painful, which leads to the appearance of cardialgia.
