Objective: Through observation STEMI directly after PCI , IRA achieve TIMI flow 3 patients ECG degree of ST segment to explore the relationship between ST segment resolution and myocardial injury and cardiac contractile function . Methods: accepted in the incidence 12h treated with primary PCI TIMI flow reached 115 cases of three patients with STEMI PCI preoperative , postoperative ECG observed ST segment measured in patients before and after surgery CK , CK - MB and cTnT; postoperative determination the LVEF; follow ΣSTR different , the patients were divided into two groups: Group A : ΣSTR <50 % , a total of 21 cases of myocardial perfusion group , Group B : ΣSTR ≥ 50 % , a total of 94 cases , for the myocardial perfusion good group ; analysis of the two groups of patients with ST segment elevation degree of CK , CK - MB , cTnT and LVEF relationship . Results : 1 . Patients were age, gender , mean arterial pressure , heart rate , pre-hospital incidence of heart failure , hypertension , and diabetes prevalence , body mass index , lipid levels showed no significant difference (P> 0.05) ; 2 . patients culprit vessel parts , coronary arteries , TIMI flow grade PCI before treatment onset to PCI time difference was not statistically significant ( P > 0.05 ) . Two groups of patients before and after surgery of CK, CK- MB level , the difference was not statistically significant ( P > 0.05 ) , the two groups of patients with preoperative cTnT difference was not statistically significant ( P > 0.05 ) , postoperative cTnT different levels of group A than group B ( 1.30 ± 0.43vs1.0 ± 0.45 , P <0.05 ) . 5 . Group BLVEF higher than group A, the difference was statistically significant ( 44.13 ± 4.83vs47.93 ± 5.23 , P <0.05 ) . Conclusion : Acute STEMI directly after PCI , TIMI blood flow to 3 , patients with ST segment elevation , perhaps better degree of myocardial tissue perfusion , a lesser degree of myocardial injury , left ventricular systolic function .
