Although the incidence of myocardial bridge (MB) has been defined in different femoral access conventional coronary angiography (FACCA) studies, the frequency of MB on radial access coronary angiography (RACA) is unknown. The aim of this study was to determine the difference in the incidence of MB between patients undergoing RACA and FACCA.
A total of 2500 consecutive patients who underwent RACA and a total of 1455 consecutive patients who underwent FACCA were retrospectively investigated to detect the presence of MB. The incidences of the groups were calculated separately and compared. The clinical and angiographic features of the patients with MB were analyzed.
MB was detected at an incidence of 10.2%, in 255/2500 patients who underwent RACA, and 1.8% in 27/1455 patients who underwent FACCA (p < 0.001). In both RACA and FACCA patients, the most involved coronary artery was the left anterior descending artery (LAD) (86.9% and 93.1%) and the mid-segment (84.9% and 88.9%) was the most affected section. Co-involvement of multiple coronary arteries by MB was 7.8% in patients who underwent RACA and 7.4% in patients who underwent FACCA. Coronary artery disease (CAD) was determined in 111 (35.7%) of the coronary arteries with MB, of which 81.9% were proximal to the MB. No significant CAD was detected in any of the vessels of 69.8% (178/255) of the patients who underwent RACA for different clinical indications.
These data demonstrated that the incidence of myocardial bridge able to be detected on RACA was much higher than FACCA.
尽管心肌桥(MB)的发生率已在不同的股动脉常规冠状动脉造影(FACCA)研究中确定,但桡动脉入路冠状动脉造影(RACA)中 MB 的频率尚不清楚。本研究旨在确定 RACA 和 FACCA 患者之间 MB 发生率的差异。
回顾性调查了 2500 例连续接受 RACA 和 1455 例连续接受 FACCA 的患者,以检测 MB 的存在。分别计算各组的发生率并进行比较。分析了 MB 患者的临床和血管造影特征。
在接受 RACA 的 2500 例患者中,MB 的检出率为 10.2%(255/2500),而在接受 FACCA 的 1455 例患者中,MB 的检出率为 1.8%(27/1455)(p<0.001)。在 RACA 和 FACCA 患者中,最常受累的冠状动脉是左前降支(LAD)(86.9%和 93.1%),最常受累的节段是中段(84.9%和 88.9%)。MB 多支冠状动脉同时受累的发生率在接受 RACA 的患者中为 7.8%,在接受 FACCA 的患者中为 7.4%。在 255 例接受 RACA 的 MB 患者中,111 例(35.7%)的冠状动脉有冠心病(CAD),其中 81.9%位于 MB 近端。在因不同临床指征接受 RACA 的 255 例患者中,81.9%(209/255)的冠状动脉无明显 CAD。
这些数据表明,在 RACA 上能够检测到的 MB 发生率远高于 FACCA。
