Patients with cardiac neurosis often have common symptoms of the cardiovascular system, including chest tightness, chest pain, palpitations, panic, abnormal shortness of breath, etc. The symptoms of patients are often obvious, but there is no organic disease basis through systematic examination, and patients are often accompanied by tension, anxiety and depression. The symptoms of chest tightness and chest pain in patients with cardiac neurosis are obvious, but often improve after exercise, suggesting that myocardial ischemia in patients with cardiac neurosis is a functional change rather than an organic change. Patients with anxiety can be treated symptomatically with alprazolam, and those with both anxiety and depression can be treated symptomatically with haloperidol and melitrexin.
