【Abstract】 AIM: To evaluate the safety and shortterm e of ultrasound angioplasty in treatment of acute myocardial infarction (AMI). METHODS: A total of 28 patients with AMI were treated by coronary ultrasound thrombolysis. The degree of stenosis was measured and analyzed with INNOVA puterized analyzing system and the changes in imaging and blood flow in IRA, CKMB value, ST segment in ECG and clinical manifestations before and after the treatment were observed to evaluate the feasibility of angioplasty with ultrasound in treating AMI. CTFC was measured immediately after essful ultrasound thrombolysis (TIMI 3). RESULTS: At least one IRA with massive thrombosis was found in all the 28 patients. The repeated angiography at the end of ultrasound thrombolysis showed no image of thrombi again and IRA achieved grade III of TIMI blood flow in 27 out of the 28 patients with AMI (potencyrecovering rate=%). The stenosis decreased significantly after the operation(± vs ±,P<) and CTFC was less than 23 count/second (mean ± count/second) in 26 patients. Disappearance of chest pain, remarkable decrease in ST segment(
± mV vs ± mV, P<) and obvious migrating forward of CKMB peak value were found in 27 patients. There were no adverse clinical events during the procedure and ho
