Effectiveness Evaluation in Thrombus Aspiration in Patients With STEMI and High Thrombotic Load

Effectiveness Evaluation in Thrombus Aspiration in Patients With STEMI and High Thrombotic Load

This study intends to evaluate thrombus on the basis of different methods for evaluating thrombus load The effect of aspiration on the prognosis of STEMI patients with high thrombotic load Provide a basis for the standardized use of aspiration; at the same time, discover the best benefit groups for thrombus aspiration
