The aim of this study was to assess the quality of angiograms obtained using 4 Fr catheters compared with 6 Fr catheters, the ease of use of the 4 Fr catheters, and the safety of patient mobilization 1 hr following 4 Fr angiography. Details of catheter performance and procedural details were recorded at the time of the angiogram. The angiographic images were scored on the quality and completeness of vessel opacification throughout systole and diastole. A total of 410 patients were recruited. There was no difference between 4 and 6 Fr for procedural variables. All angiograms were considered to be of diagnostic quality. The angiographic scores for the right coronary artery and left ventricular injections were no different between 4 and 6 Fr. However, the angiographic scores for the left anterior descending and circumflex arteries were lower with 4 than with 6 Fr (both P < 0.05). Patients who had 4 Fr angiography mobilized safely at 1 hr and reported significantly less discomfort and bruising than 6 Fr patients. Good-quality diagnostic coronary angiograms can be achieved using 4 Fr catheters with the advantage of earlier postprocedural mobilization and reduced discomfort and bruising for the patient.
本研究的目的是评估使用4F导管与6F导管获得的血管造影照片的质量、4F导管的易用性以及4F血管造影术后1小时患者活动的安全性。在血管造影时记录导管性能细节和操作细节。根据整个收缩期和舒张期血管显影的质量和完整性对血管造影图像进行评分。共招募了410名患者。在操作变量方面，4F和6F之间没有差异。所有血管造影照片均被认为具有诊断质量。4F和6F在右冠状动脉和左心室注射的血管造影评分上没有差异。然而，4F时左前降支和回旋支动脉的血管造影评分低于6F（均P<0.05）。接受4F血管造影的患者在1小时时能够安全活动，且与6F患者相比，报告的不适和瘀伤明显更少。使用4F导管可以获得高质量的诊断性冠状动脉造影照片，其优点是术后能更早活动，且患者的不适和瘀伤减少。
