Coronary Catheterisation Does Not Lead to Retinal Artery Emboli in Short-Term Follow-Up of Cardiac Patients

对心脏病患者的短期随访研究发现:冠状动脉导管插入术并未导致视网膜动脉栓塞

Abstract

摘要

Background and Purpose— There is emerging evidence that coronary catheterization can cause cerebrovascular embolization. We aimed to assess the proportion of cardiac patients with retinal emboli before coronary catheterization and the proportion with newly developed retinal embolism shortly after coronary catheterization.

背景和目的——最近一些新证据认为,冠状动脉导管插入术会引起脑血管栓塞。我们的研究目的是评估心脏病患者在冠状动脉导管插入术前视网膜动脉栓塞的比例,以及在冠状动脉导管插入术后短期内新发生视网膜动脉栓塞的比例。

Methods— Ninety-seven patients attending Westmead Hospital for coronary catheterization between December 2005 and February 2006 were recruited. Medical history, physical examination, and pre- and postcatheterization photography of 5 retinal fields was performed. The proportion of patients with new retinal emboli was assessed by comparing post- and precatheterization retinal photographs.

方法——将2005年12月~2006年2月在Westmead医院接受冠状动脉导管插入术的97名患者纳入研究。收集所有患者的病史、体格检查和导管插入术前术后5个视网膜区的影像资料。通过比较术前和术后的视网膜图像来确定新发视网膜动脉栓塞的患者比例。

Results— Before catheterization, retinal emboli were observed in 5 patients (5.2%) and were significantly associated with higher body mass index (P=0.007). The presence of angiographic coronary artery disease was not significantly associated with preexisting retinal emboli. In 97 patients, we found no new emboli within the 16-hour (median: range 4 to 45 hours) postcoronary catheterization period.

结果——导管插入术前,有5名患者(5.2%)存在视网膜动脉栓塞,与高体重指数显著相关 (P=0.007)。血管造影证实为冠心病与术前是否存在视网膜动脉栓塞无明显相关性。冠状动脉导管插入术后中位数时间16小时(4~45小时)内,我们在97名患者中未发现1例新发视网膜动脉栓塞。

Conclusions— Asymptomatic retinal emboli are relatively common in patients being assessed for coronary artery disease. We found no evidence suggesting coronary catheterization contributes to retinal embolism shortly after the procedure.

结论——无症状的视网膜动脉栓塞在明确冠心病的患者中相对常见,我们没有发现冠状动脉导管插入术与术后短期内视网膜动脉栓塞有关的证据。

冠状动脉导管插入术导致脑血管栓塞的证据不足

最近一些新证据认为,冠状动脉导管插入术会引起脑血管栓塞。澳大利亚悉尼大学Westmead医院的研究人员在8月《Stroke》杂志上发表文章称,无症状视网膜动脉栓塞在冠心病患者中相对常见,他们没有发现冠状动脉导管插入术与术后短期内视网膜动脉栓塞有关的证据。(Stroke 2007 38: 2370 - 2352)

研究人员纳入了2005年12月~2006年2月在Westmead医院接受冠状动脉导管插入术的97名患者。收集所有患者的病史、体格检查和导管插入术前术后5个视网膜区的影像资料。通过比较术前和术后的视网膜图像来确定新发视网膜动脉栓塞的患者比例。

导管插入术前,有5名患者(5.2%)存在视网膜动脉栓塞,与高体重指数显著相关 (P=0.007)。血管造影证实为冠心病与术前是否存在视网膜动脉栓塞无明显相关性。冠状动脉导管插入术后中位数时间16小时(4~45小时)内,97名患者中未发现1例新发视网膜动脉栓塞。

因此,作者认为,无症状视网膜动脉栓塞在明确冠心病的患者中相对常见,目前还无足够证据认为冠状动脉导管插入术与术后短期内视网膜动脉栓塞有关。
