目的探讨急性心肌梗死行急诊介入治疗后心肌Blush分级与左室功能恢复的影响。方法 88例成功接受急诊介入治疗的急性心肌梗死患者,根据心肌Blush分级,将所有患者分为Blush分级<2级组(n=20)和Blush分级≥2级组(n=68)。术后14d,行超声心动图检查测定左室收缩末期容积指数(LVESVI)、左室舒张末期容积指数(LVEDVI)和左室射血分数(LVEF),并进行比较。结果术后14d时,与Blush分级≥2级组比较,Blush分级<2级组LVESVI和LVEDVI增大,LVEF降低,P<0.05,差异有统计学意义。结论 PCI术后TIMI血流3级者的预后与心肌Blush分级有关,进行心肌Blush分级对临床治疗有指导价值。
Objective To investigate the effect of acute myocardial infarction on Blush grading and left ventricular functional recovery after emergency interventional therapy. Methods 88 patients with acute myocardial infarction who were successfully treated with emergency intervention were divided into two groups according to Blush grading: blush grade 2 (n = 20) and blush grade ≥ grade 2 (n = 68). At 14 days after operation, the left ventricular end-systolic volume index (LVESVI), left ventricular end-diastolic volume index (LVEDVI) and left ventricular ejection fraction (LVEF) were measured by echocardiography and compared. Results At 14th day after operation, LVESVI, LVEDVI and LVEF of Blush grade 2 were significantly higher than those of Blush grade 2 or higher (P <0.05), and the difference was statistically significant. Conclusions The prognosis of grade 3 TIMI flow after PCI is related to the Blush classification of myocardium. Blush classification of myocardium has guiding value in clinical treatment.
