Secondly, consider for real heart pain, common causes are myocarditis or coronary atherosclerotic heart disease and other causes: a. Non-cardiac diseases: commonly there are various chemical and physical factors that stimulate intercostal nerve sensory fibers, posterior spinal root afferent fibers, sensory fibers innervating the heart and aorta, vagus nerve sensory fibers innervating the trachea and bronchus and esophagus, or sensory fibers of the phrenic nerve when they can cause chest pain. If excessive movement leads to damage to the intercostal nerve or lesions in the trachea and bronchus in the chest cavity, patients can be mistaken for heart pain. Second, heart disease: 1, myocarditis: common cause because of viral infection, the onset of acute and slow varying, the milder can be completely asymptomatic, the heavier even appear cardiogenic shock and sudden death, a few were fulminant leading to acute pump failure or sudden death. The symptoms are precordial tingling, palpitations or cardiac arrest, which require timely treatment; 2, coronary atherosclerotic heart disease: referred to as coronary heart disease, there will be myocardial ischemia, paroxysmal angina and other conditions, the patient feels a crushing pain in the forehead, suffocating sensation, burning sensation, occasionally accompanied by a sense of imminent death.
