Objective: The purpose of this case study was to report the symptom improvement effect of integrative Korean medicine treatment based on Pyongsim Solution: Cheonwangbosim-dan in a patient with variant angina and asthma symptoms. Methods: This 68-year-old male patient was treated with Pyongsim Solution, Gamihyangsayukgunja-tang, Gwakhyangjunggi-san, acupuncture, pharmacopuncture, and cupping therapy for 24 days. The European Quality of Life-5 Dimensions-5 Levels profile, Numerical Rating Scale score, and pulse rate per minute were measured on admission, at two weeks of hospitalization, and upon discharge to assess the clinical outcomes. Results: After treatment, the "mobility" dimension profile of the European Quality of Life-5 Dimensions-5 Levels changed from 1 to 1, "self-care" changed from 1 to 1, "usual activity" changed from 3 to 2, "pain/discomfort" changed from 4 to 3, and "anxiety/depression" changed from 3 to 2. The Numerical Rating Scale score for chest pain decreased from 7 to 5, chest tightness decreased from 6 to 4, sleep disturbance decreased from 6 to 3, polydipsia decreased from 5 to 3, and stomach discomfort decreased from 5 to 3. All the profiles of these five dimensions were unchanged for 11 days in the period between the two weeks of hospitalization and discharge. There were also no changes in the profiles of either "mobility" or "self-care" throughout the entire 24-day hospitalization period. Conclusion: This case report shows that integrative Korean medicine treatment based on Pyongsim Solution can improve the symptoms of patients with variant angina and mild intermittent asthma, suggesting that Pyongsim Solution could be an important herbal medication for treatment.
