9、肿瘤可有胸部闷痛。Associated features影响胸痛的因素Angina Pectoris is often indused by tension. It can be released by taking nitroglycerin tablets. Myocardial infarction can be indentified with continuing pain which is not to be released by taking nitroglycerin tablets.心绞痛常于用力或精神紧张时诱发，呈阵发性，含服硝酸甘油片迅速缓解；心肌梗死常呈持续性剧痛，虽

10、含服硝酸甘油片仍不缓解Cardiac neurosis is often the reason of chest pain. It can be relieved by movement.心脏神经官能症所致胸痛则常因运动反而好转The chest pain of pleurisy, pneumothorax, and pericarditis can often be exacerbated by cough or deep breathing 胸膜炎、自发性气胸、心包炎的胸痛常因咳嗽或深呼吸而加剧Associated features影响胸痛的因素Neuromusculoskeletal C
