摘要
1996～1997年间对11例内科治疗无效的不稳定心绞痛患者进行冠状动脉造影及冠状动脉内支架植入术治疗。造影发现:简单单支病变者3例(27.3％),单支多发病变者2例(18.1％),双支病变者3例(27.3％),3支病变者3例(27.3％)。平均狭窄长度(22.3±6.9)mm。平均狭窄直径(89.3±10.3)％。共植入12枚支架,LAD 10枚(83.3％),RCA 2枚(16.7％),LCX 0枚,其中1例植入2枚支架。支架植入成功率100％,无并发症发生。术后造影复查平均狭窄直径为0～10％,心绞痛较术前明显减轻或消失,心电图缺血性ST-T改变改善或恢复,术后两周运动试验均由阳性转为阴性。超声心动图提示左房内径(34.74±3.63)mm,左室内径(52.20±4.91)mm,左室射血分数0.65±0.11,明显优于术前的左房内径(39.93±3.21)mm,左室内径(56.64±5.47)mm,左室射血分数0.48±0.15。随访1～8个月均存活,仅1例经冠脉造影证实发生支架部位再狭窄。说明冠脉内支架是治疗冠状动脉狭窄,增加冠状动脉血流,保护心脏功能,提高患者生活质量的一种有效方法。
Angiography and intracoronary stent was performed in 11 patients with unstable angina in our hospital from 1996 to 1997- The group was comprised of 6 men and 5 women,mean age was (56. 6 ± 9. 7) years. All patients presented with Canadian Cardiovascular Society Class Ⅲ and Ⅳ angina. There were single vessel lesion in 5 cases,double vessel lesion in 3 cases,and triple vessel lesion in 3 cases. Mean lesion length was (22. 3 ± 6. 9)mm and average diameter of stenosis before procedure was (89. 3 ± 10. 3)%. Twelve intracoronary stents were implanted, 10 in LAD and 2 in RCA. One patient received 2 stents. The procedure success rate was 100%. After the stents implanted, average diameter of stenosis decreased to 0 ~ 10 %, ischemic ST-segment and T-wave abnormalities on ECG became improvable or normal;treadmill test changed from positive to negative;the diameter of left atrial and left ventricular on UCG were reduced,ejection fraction increased significantly. The results indicated that the elective stent placement as compared with angioplasty .had a higher clinical success rate and reduced the incidences of restenosis and for subsequent revascularization. Coronary stent provides beneficial effects in increasing coronary blood flow,preventing left ventricular function and improving patient's living quality.
