Coronary stenting in women has been associated with worse results in terms of morbidity, mortality, and restenosis rate in the bare-metal stent era, possibly due to higher risk profile and smaller coronary vessels. Although drug-eluting stents have equalized clinical results, no data are available on long-term outcomes between sexes.
To evaluate the role of sex in acute, mid-term, and long-term clinical outcome after sirolimus-eluting stent (SES) implantation.
We retrospectively evaluated 1186 patients, 970 (81.8%) male and 216 (18.2%) female, treated with SES implantation between April 2002 and December 2005.
Women were older (P=0.049), more likely to have hypertension (43.5 vs. 33.7%, P=0.006), single-vessel disease (63.9 vs. 42.5%, P=0.03), and unstable angina (16.6% vs. 9.2%, P=0.001) and more frequently received small (≤ 2.75 mm) vessel stenting (39.3 vs. 28.2%, P=0.001). The two groups were similar for lesion and procedural characteristics. Overall, the stent thrombosis rate was 0.4% (0.5% in women vs. 0.3% in men, P=not significant). At 6-month follow-up, no significant difference in major adverse cardiac event was observed. Long-term follow-up (median time 33.2 months), available in 180 (83.3%) women and 720 (75%) men, showed higher angina recurrence rate (17.7 vs. 11%, P=0.013), percutaneous coronary re-intervention (16.1 vs. 8.7%, P=0.001) and target vessel revascularization (3.9 vs. 0.9%, P=0.001) in women compared with men. Late stent thrombosis, need for coronary artery bypass grafting, and mortality were similar in both groups.
No sex difference was observed in acute and 6-month outcome after SES implantation despite older age, more unstable clinical presentation, and more frequent small vessel stenting in women. However, long-term clinical follow-up (up to 5 years) in women showed higher symptom recurrence and target vessel revascularization rate but no difference in overall major adverse cardiac events.
在裸金属支架时代,女性冠状动脉支架置入术在发病率、死亡率和再狭窄率方面的结果较差,这可能是由于女性具有更高的风险特征和更细小的冠状动脉血管。尽管药物洗脱支架使临床结果趋于均衡,但尚无关于两性长期预后的数据。
评估性别在西罗莫司洗脱支架(SES)植入术后急性、中期和长期临床结局中的作用。
我们回顾性评估了2002年4月至2005年12月期间接受SES植入术的1186例患者,其中男性970例(81.8%),女性216例(18.2%)。
女性年龄更大(P = 0.049),更易患高血压(43.5%对33.7%,P = 0.006)、单支血管病变(63.9%对42.5%,P = 0.03)和不稳定型心绞痛(16.6%对9.2%,P = 0.001),并且更频繁地接受小(≤2.75 mm)血管支架置入术(39.3%对28.2%,P = 0.001)。两组在病变和手术特征方面相似。总体而言,支架血栓形成率为0.4%(女性为0.5%,男性为0.3%,P无统计学意义)。在6个月随访时,未观察到主要不良心脏事件有显著差异。180例(83.3%)女性和720例(75%)男性有长期随访数据(中位时间33.2个月),结果显示女性心绞痛复发率(17.7%对11%,P = 0.013)、经皮冠状动脉再次干预率(16.1%对8.7%,P = 0.001)和靶血管血运重建率(3.9%对0.9%,P = 0.001)均高于男性。两组的晚期支架血栓形成、冠状动脉旁路移植术需求和死亡率相似。
尽管女性年龄更大、临床表现更不稳定且更频繁地接受小血管支架置入术,但在SES植入术后的急性和6个月结局中未观察到性别差异。然而,女性的长期临床随访(长达5年)显示症状复发率和靶血管血运重建率更高,但总体主要不良心脏事件无差异。
