| 摘 要： | 目的 :应用血管内多普勒导丝测量血流速度评价冠状动脉造影血流TIMI分级 (TIMI FG)及其计帧值 (TIMI FC)准确性。方法 :在 11只猪右冠状动脉狭窄动物模型和 36例冠状动脉造影及 17例行血管介入治疗患者中 ,比较TIMI FG和TIMI FC与血流速度相关性。结果 :①随动物模型充盈球囊造成血管狭窄程度加重 ,血流速度减慢、TIMI FG下降、TIMI FC变大。② 17例患者 2 5支血管介入治疗后 ,血流速度增加 ,TIMI FG上升、TIMI FC变小。③TIMI FC与血流速度呈中度负相关 ;而TIMI FG和TIMI FC变化值与血流速度变化值相关性提高。结论 :冠状动脉造影TIMI FC判断血流速度具有一定准确性 ,尤其对血流速度变化更佳

| Abstract: | Purpose:To investigate the relationship between coronary angiographic thrombolysis in myocardial infarction trial blood flow grade (TIMI FG) or TIMI frame count (TIMI FC) and intracoronary Doppler flow velocity(V).Methods: In swine coronary stenosis model (n=11), 36 patients with coronary arteriography, 17 patients with percutaneous transluminal coronary angioplasty (PTCA), TIMI FG, TIMI FC and V were measured. Results: Angiographic TIMI FC was negatively correlated with V in patients and animal.Conclusion: TIMI FC can be used for assessing coronary artery flow. |
