The Cohort Study of East Chinese Takayasu's Arteritis (ECTA-cohort Study)
The Takayasu arteritis (TA) is a rare inflammatory large vessel arteritis which often occurs women in Aisa, one of which is China. The rare cases restricted the development of intervention strategy, especially in female patients who plan to be pregnant. So investigators try to recruit as many TA participants as possible to build a TA cohort so that investigators could manage patients much more professionally and standardized and explore the better interventional strategy for a better outcome as well, with full use of blood and vascular tissues.
