Hello,
Any chest pain is cardiac in origin unless proved otherwise.
Chest pain can happen because of gastrointestinal
causes like GERD, esophageal spasm, peptic ulcer disease, psychogenic like anxiety and depression, neuromusculoskeletal like thoracic outlet syndrome and costochondritis, pulmonary like pulmonary embolism and involvement of pleura and cardiac causes. EKG, stress test and Stress echo need to be done to rule out any cardiac cause.
