【摘要】 目的探讨肌钙蛋白T(CTNT)对不稳定型心绞痛预后的临床价值。方法为我院83例不稳定型心绞痛患者检测肌钙蛋白T及肌酸激酶同工酶(CK-MB)水平,并比照两组阳性与阴性患者发生心脏病变的几率。结果所有患者中,合计56例肌钙蛋白T为阳性、27例为阴性。肌钙蛋白T阳性组病变率为21.43%,显著高于肌钙蛋白T阴性组的14.81%,差异有统计学意义(P<0.05)。所有患者中,合计45例CK-MB为阳性、38例为阴性。CK-MB阳性组病变率为20%,与CK-MB阴性组的18.42%相比,差异无统计学意义(P>0.05)。结论不稳定型心绞痛患者化验肌钙蛋白T水平其诊断特异性及精度优于肌酸激酶同工酶,可有效判定患者的预后。更多还原

【Abstract】 Objective To explore the clinical value of cardiac troponin T(CTNT) on the prognosis of unstable angina pectoris. Methods 83 patients with unstable angina pectoris who were admitted to our hospital were tested CTNT and CK-MB levels, and the ratios of cardiac abnormalities for patients of positive and negative results were compared. Results Of all patients, 56 showed positive CTNT results and 27 negative. The ratio of abnormalities in the group of positive CTNT results was 21.43%, significantly higher than that of 14.81% in the negative group, and the difference was statistically significant(P < 0.05). Of all patients, 45 showed positive CK-MB results and 38 negative. The ratio of abnormalities in the group of positive CK-MB results was 20%, which was not significantly different from that of 18.42% in the negative group(P > 0.05). The difference was not statistically significant. Conclusion The diagnostic specificity and precision of CTNT test for patients with unstable angina pectoris are better than those of CK-MB test. CTNT test is effective in determining patients’ prognoses.更多还原
