目的:调查研究1985年~1997年期间冠心病介入治疗的演变。
方法:回顾性分析比较西京医院1985年~1994年与1995年~1997年期间所有行冠心病介入治疗病历完整患者的临床资料。
结果:早期病例109例,近期266例,近期病例组年龄增大(58±10比54±11,P<0.05),不稳定性心绞痛(72%比59%,P<0.05),多支病变(66%比59%,P<0.05),B、C型复杂病变(81%比63%,P<0.05)增加,支架应用普遍(6.4%比2.7%,P<0.01)。但介入治疗病例(90%比83%,P<0.05)、病变(91%比80%,P<0.05)成功率提高,治疗后残余狭窄减轻[(6±14)%比(27±12)%,P<0.01],住院期间严重并发症发生率下降(3.0%比6.4%,P<0.25),死亡(1.5%比3.7%,P<0.25)、Q波心肌梗塞(1.9%比4.6%,P<0.25)、死亡或Q波心肌梗塞(2.6%比6.4%,P<0.10)均降低,球囊扩张后急性闭塞发生率不变(4.5%比4.6%,P=NS)。
结论:随着经验积累,例数增多和支架的广泛应用,冠心病介入治疗的适应证扩大,成功率提高,严重并发症发生率下降。但由于年手术量仍偏少,介入治疗的水平仍需进一步提高。

Objective: To investigate the evolution of percutaneous transluminal revascularization in a medical center from 1985 to 1997.
Methods: In this retrospective study, 109 consecutive treated patients with complete data in Xijing Hospital during 1985~1994 were studied and compared with 266 patients during 1995~1997.
Results: The new cohort of patients was older (58±10 vs. 54±11 years, p<0.05), and had a significantly higher proportion of unstable angina (72% vs. 59%, p<0.05), multivessel disease (66% vs. 59%, p<0.05), and complex lesions (type B and C: 81% vs. 63%, p<0.05). Intracoronary stenting was more widely used in the new cohort (64% vs. 2.7%, p<0.01). Despite these differences, the success rates were higher in the 1995~1997 cohort (lesion success rate: 91% vs. 80%, patients success rate 90% vs. 83%, p<0.05). The new patient cohort tended to have less frequent serious complications (3.0% vs. 6.4%, p<0.25), fewer Q-wave myocardial infarction (1.9% vs. 4.6%, p<0.05), fewer combined death and Q-wave myocardial infarction (2.6% vs. 6.4%, p<0.01). But the rate of abrupt closure after balloon angioplasty remained the same (4.5% vs. 4.6%, p=NS).
Conclusion: With the increase of experience and case-volume and the wide use of stents, the inhospital outcomes improved despite the greater patient acuity. However, due to still lower annual case-volume, the outcome of percutaneous coronary revascularization remains to be enhanced further.
