Objective:To investigate myocardial viability post primary percutaneous coronary intervention(PCI) in patients with acute myocardial infraction(AMI) in terms of TIMI myocardial perfusion grade(TMP).

Methods A total of 57 consecutive acute myocardial infarction patients with ST-segment elevation were divided into two groups:anterior wall and inferior wall,all the patients undergoing PCI within 6 h~12 h,the ST-segment elevation and TIMI myocardial perfusion(TMP)of 57 patients with AMI before PCI and after PCI wer.

Changes of myocardial perfusion levels after percutaneous coronary intervention in coronary artery disease patients with different stenosis degrees;

Selecting of reference data from database for quantitative analysis of myocardial perfusion computed tomography;

Establishment of quantitative analysis reference database for myocardial perfusion computed tomography;

Objective: To investigate the effect of plasma levels of IL-8,sICAM-1 on myocardial reperfusion with patients of acute myocardial infarction after PCI.

Myocardial reperfusion evaluated by myocardial blush grade after thrombolysis in acute myocardial infarction;

CAG shows that the blood flow under the second branch of LAD is interrupted and the blood flow is of TIMI 0 grade.

Hypotension effects after protamine administration during myocardial reperfusion period in open heart surgery;
