If a patient has heart pain on inspiration, the first thing to consider is high-risk chest pain, such as acute coronary syndrome, tension pneumothorax, and pulmonary embolism aortic coarctation, all of which are described above. These diseases have a low incidence but high mortality rate and are usually the first to get attention. In addition, for diseases of the respiratory system, such as large lung infections, traffic pneumothorax, open pneumothorax, pleurisy, acute bronchitis, in this case, the precordial region will also have a sharp pain on inspiration. For some patients with intercostal neuralgia and shingles pain, the precordial region may also be painful after inspiration. For diseases of cardiac origin, such as coronary artery disease, unstable angina, acute myocarditis, pericardial compression and other conditions, the heart will also have compression symptoms and pain during inspiration.
