The Assessment of Acute /Chronic Phase in Patients With Ischemic Cerebral Stroke Using TCM Diagnostic Tools

Attending Physician, Department of Chinese Medicine

Cerebral infarction is the second cause of death and the third cause of disability. More than 13.7 million patients worldwide are diagnosed with stroke every year, and the number of deaths is 5.5 million, of which ischemic stroke is the major type, accounting for 87%. Sequelae of stroke are problems that require long-term medical care. If we can intervene and assist with Traditional Chinese Medicine (TCM) at early stage, it will be a great boon for patients. In clinical practice, TCM collects data as the basis for diagnosis through the four diagnostic methods-look, listen, question, and feel the pulse. Among these, tongue diagnosis and pulse diagnosis belong to the categories of look and feel the pulse. At present, the objective examination instruments of TCM developed are mainly tongue diagnostic instruments and pulse diagnostic instruments. Therefore, we hope to utilize tongue and pulse diagnoses as the main reference to analyze the changes in ischemic stroke stages. The data of this study are collected from China Medical University Hospital and YuanRung Hospital-for further statistical analysis. Ischemic stroke patients (ICD-10: I63) who were hospitalized within 1 week from the date of diagnosis were eligible to join this research project. Tongue and pulse examinations were collected once per week within 1 month. A total of 4 tongue-pulse examinations were collected in each case, which were categorized into acute stage (24 hours to 1 week), subacute stage (1 to 3 weeks) and chronic stage (more than 3 weeks). [30] This research is to study the changes of tongue and pulse diagnoses in acute, subacute and chronic stages among ischemic patients who receive TCM diagnosis and treatment. Through utilizing objective evaluation of Chinese and Western medical examination instruments, we hope to establish clear diagnostic standards for TCM syndrome types, so as to evaluate the efficacy of clinical diagnosis and treatment. The goal is to improve the quality of TCM care and to provide Chinese and Western integrated treatment for stroke patients in the future. This research can also serve as a reference for related TCM research and development.
