STE-LDDSE has a high value of detecting VM. Parallel diagnostic test for LS and LSr is the best choice in detecting VM in the patients with STEMI and is more sensitive for the patients with type 2 DM. It will be more effectively to guide the further treatment and to evaluate the prognosis of the STEMI patients.
