摘要：目的：：探讨冠心病病人心功能不全改善前后血清Ⅲ型前胶原(PCⅢ)、层粘连蛋白(LN)、透明质酸(HA)的含量变化及其临床意义。方法：将78例冠心病病人分为观察组和对照组, 观察组行冠状动脉造影及左心室造影和超声心动图检查，并测定左室功能，术后每天用异舒吉20mg, 共用14d，治疗结束后再次行超声心动图检查测定左心室功能。两组病人于治疗前后分别测定血清PCⅢ、LN、HA的浓度变化。结果：观察组病人的血清PCⅢ、LN、HA浓度较对照组明显增加(t=14.17～16.69,P<0.01)，观察组病人治疗后血清PCⅢ、LN、HA浓度较治疗前明显下降(t=2.352～4.271,P<0.05,0.01)。结论：血清PCⅢ、LN、HA在冠心病心功能不全的发生、发展中起重要的作用, 具有一定的临床参考价值。

    Abstract：Objective： To explore the effect and clinical signification of changes in serum procollagen typeⅢ(PCⅢ),laminin(LN)and hyaluronic acid(HA) levels in patients with heart dysfunction. Method： 78 patients with dysfunction were divided into observed group and control group. The observed group undergone coronary angiography (CAG) , left ventricular angiography and echocardiography to observe the function of left v entricular. The postoperative patients were treated with isoket 20 mg iv drip, qd for 14 days. The morning venous blood was collected to determine the PCⅢ、LN、HA in these patients one day after therapy, and the echocardiography were undergone again to observe the function of left ventricular. Result：The observed group compared with controlled group. The PCⅢ、LN、HA levels in blood serum increased significantly (t=14.17～16.69,P<0.01). The PCⅢ、LN、HA levels observed group after therapy were significantly lower than those before therapy(t=2.352～4.271,P<0.05). Conclusion： PCⅢ、LN、HA in blood serum play important roles in occurance and development of coronary heart disease and heart dysfunction. ......
