Variant angina causes chest pain due to abnormal coronary vasospasms. A 60-year-old male who was diagnosed with variant angina was admitted to the Oriental Medicine Hospital and treated with herbal medicines, including Pyungjinsujeom-san and Simjeok-hwan. After treatment, the frequency of chest pain and use of nitroglycerin decreased. Subjective symptoms of chest pain measured using a numerical rating scale (NRS) also decreased. These improvements persisted throughout the hospitalization period. In conclusion, Korean medicines, including Pyungjinsujeom-san and Simjeok-hwan, can be effective for patients with chest pain due to variant angina.
