Abstract: Objective: To study the effect of thrombus aspiration combined with tirofiban on muscle tissue perfusion and clinical prognosis of STEMI patients received interventional therapy. Methods: 120 cases STEMI patients received interventional therapy were enrolled and randomly divided into observation group given thrombus aspiration combined with tirofiban and control group given conventional therapy. Then myocardial enzymes and cardiac function index were detected. Results: observation group TIMI, MBG (2.42±0.34, 2.36± 0.45) ,E peak (75.22±8.39) cm/s ,E/A ratio (1.412 ±0.165), LVEDD (56.39±5.98) mm, LVEF (67.38±7.25) % were significantly higher than control group . AST, LDH, CK, CK - MB (28.1 ±4.5, 154.6 ±34.5 ,34.5 ±28, 18.4±3.3) U/L, hs - cTnT (7.92±1.01) ng/L, adverse cardiovascular events (5%) were significantly lower than that control group (P < 0.05). Conclusion: thrombus aspiration combined with tirofiban have positive clinical value for it can improve myocardialtissue perfusion and heart function |
