Abstract:
Objective To study the probability of evaluating myocardial tissue perfusion by corrected TIMI frame count (CTFC) after successful percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods Sixty-three patients with their first acute myocardial infarction (AMI) who accepted primary coronary intervention were recruited. All these patients got TIMI 3 grade flow. CTFC was measured after successful PCI in these patients. Wall Motion Score Index (WMSI) assessed by two-dimensional echocardiography before and one month after PCI and the correlation studied between CTFC and WMSI. Results According to CTFC the patients were divided into two groups. Improvement of WMSI in the TIMI 3 fast group was significantly greater than that of the TIMI 3 slow group. CTFC had a significant correlation with the change in WMSI. Elapsed time from the onset of symptoms to reperfusion in the TIMI slow group was significantly longer than that of the TIMI fast group. Conclusion CTFC is a quantitative, and reproducible index of coronary blood flow. Lower CTFC is associated with greater functional recovery and could supply evidence for additional adjunctive treatment.
