摘要 目的探讨中高海拔地区汉族与藏族人群冠状动脉畸形的差异。方法入选2010至2015年所有在青海省心脑血管病专科医院行冠状动脉CT血管成像且居住在青海高原(海拔1800—7720m)的成年人7028名,进行回顾性分析。其中,汉族6391名,藏族637名。通过分析冠状动脉CT血管成像结果,比较汉族与藏族人群的冠状动脉畸形特征差异。结果(1)汉族人群的冠状动脉畸形发生率为1.596%(102/6391),藏族人群的冠状动脉畸形发生率为4.239%(27/637),差异有统计学意义(P〈0.001)。(2)汉族的冠状动脉畸形患者中男性占64.7%(66/102),藏族的冠状动脉畸形患者中男性占74.1%(20/27),差异无统计学意义(P:0.359)。(3)汉族患者中冠状动脉畸形发生在左侧占64.4%(67/104),藏族患者中冠状动脉畸形发生在左侧占55.6%(15/27),差异无统计学意义(P=0.396)。(4)汉族人群的良性冠状动脉畸形发生率为0.720%(46/6391),藏族人群的良性冠状动脉畸形发生率为2.200%(14/637),差异有统计学意义(P〈0.001);汉族人群的潜在危险冠状动脉畸形发生率为0.876%(56/6391),藏族人群的潜在危险冠状动脉畸形发生率为2.041%(13/637),差异有统计学意义(P=0.004)。(5)共发现冠状动脉畸形10种,其中,左冠状动脉起源于右冠状动脉窦[汉族为0.046%(3/6391)、藏族为0.471%(3/637),P=0.012]、左回旋支起源于右冠状动脉窦[汉族为0.046%(3/6391)、藏族为0.471%(3/637),P=0.012]、右冠状动脉开口于左冠状动脉窦或左前降支[汉族为0.704%(45/6391)、藏族为1.570%(10/637),P=0.018]的发生率汉族和藏族之间差异有统计学意义。结论中高海拔地区藏族人群的冠状动脉畸形发生率高于汉族人群,良性冠状动脉畸形的发生率也高于汉族人群。 Objective To analyze the differences of coronary artery anomalies between Han and Tibetan nationality living in middle and high altitude. Methods A total of 7 028 adults living in the Qinghai Plateau ( 1 800--7 720 m altitude) , who underwent coronary CT angiography in Qinghai Cardio- cerebro-vascular Disease Special Hospital between 2010 to 2015, were included in this study. There were 6 391 cases of the Han nationality and 637 cases of the Tibetan nationality. The differences of coronary artery anomalies between klan and Tibetan nationality were analyzed retrospectively. Results ( 1 ) Incidence of coronary artery anomalies was lower in Han nationality than in the Tibetan nationality ( 1. 596% ( 102/6 391 ) vs. 4. 239% (27/637) ,P 〈 0. 001 ). (2) There was 64. 7% (66/102) male residents with coronary artery anomalies in Han nationality, and 74. 1% (20/27) male residents with coronary artery anomalies in Tibetan nationality ( P = 0. 359 ). ( 3 ) Left side coronary artery anomalies in Han nationality was similar as in Tibetan nationality (64.4% (67/104) vs. 55.6% (15/27) , P =0. 396). (4) Incidence of benign coronary artery anomalies was significantly lower in Han nationality than in Tibetan nationality (0. 720% (46/6 391 ) vs. 2. 200% ( 14/637 ) , P 〈 0. 001 ) . Incidence of potentially dangerous coronary artery anomalies was also significantly lower in Han nationality than in Tibetan nationality (0. 876% (56/6 391 ) vs. 2.041% (13/637) , P =0. 004). (5)Ten kinds of coronary artery anomalies were found in this study. There were significant differences between Han and Tibetan nationality in left coronary artery originated from right coronary sinus(O. 046% (3/6 391 ) vs. 0. 471% (3/637) ,P =0. 012), in left circumflex branch originated from right coronary sinus ( 0. 046% ( 3/6 391 ) vs. 0. 471% ( 3/637 ), P = 0. 012 ), and opening of right coronary artery in left coronary sinus or left anterior descending (0. 704% (45/6 391 )vs. 1. 570% (10/637) ,P = 0. 018). Conclusion The incidences of coronary artery anomalies and benign coronary artery anomalies were significantly lower in Han nationality residents than that of the in Tibetan nationality residents living in middle and high altitude.
