One of the downsides of percutaneous coronary intervention (PCI) is stent failure which could be related to stent underexpansion. Hence, PCI based on an accurate coronary artery size obtained from intracoronary imaging is tremendously important. Until now, there is no data about all coronary artery dimensions in the Southeast Asian population performed by intravascular ultrasound (IVUS). The coronary artery size of 153 patients with chronic coronary syndrome (CCS) in acute or chronic settings who underwent percutaneous coronary intervention (PCI) with IVUS was examined. The mean artery size and its predictors were analyzed.
There were 153 patients with 633 coronary artery segments: the mean left main (LM) external elastic membrane (EEM) diameter and cross-sectional area (CSA) were 5.02 ± 0.43 mm and 19.93 ± 3.48 mm, proximal left anterior descending artery (LAD) 4.25 ± 0.42 mm and 14.34 ± 2.85 mm, the mid-LAD 3.86 ± 0.39 mm and 11.70 ± 2.24 mm, the distal LAD 3.32 (2.83-4.30) mm and 8.77(6.23-14.99) mm, the proximal left circumflex artery (LCX) 3.91 ± 0.42 mm and 12.07 ± 2.53 mm, the distal LCX 3.51 ± 0.47 mm and 9.90 (5.09-14.20) mm, the proximal right coronary artery (RCA) 4.50 ± 0.48 mm and 16.14 ± 3.43 mm, the mid-RCA 4.16 ± 0.420 mm and 13.74 ± 2.72 mm, the distal RCA 3.81 ± 0.41 mm and 11.59 ± 2.46 mm, respectively. Body surface area (BSA) is an independent predictor for the majority of epicardial coronary arteries with a positive linear relationship.
The mean artery size of the Indonesian population was comparable with previous studies. The knowledge of coronary artery size will help the clinician to have a reference for intervention, especially when no intravascular imaging is available.
经皮冠状动脉介入治疗（PCI）的一个缺点是支架失败，这可能与支架扩张不足有关。因此，基于从冠状动脉内成像获得的准确冠状动脉大小进行PCI极为重要。到目前为止，尚无关于东南亚人群通过血管内超声（IVUS）测量的所有冠状动脉尺寸的数据。对153例急性或慢性环境下患有慢性冠状动脉综合征（CCS）并接受IVUS引导下经皮冠状动脉介入治疗（PCI）的患者的冠状动脉大小进行了检查。分析了平均动脉大小及其预测因素。
153例患者共有633个冠状动脉节段：左主干（LM）的平均外弹力膜（EEM）直径和横截面积（CSA）分别为5.02±0.43mm和19.93±3.48mm，左前降支近端（LAD）为4.25±0.42mm和14.34±2.85mm，LAD中段为3.86±0.39mm和11.70±2.24mm，LAD远端为(3.32(2.83 - 4.30)mm)和(8.77(6.23 - 14.99)mm)，左旋支近端（LCX）为3.91±0.42mm和12.0(7±2.53mm)，LCX远端为3.51±0.47mm和9.90((5.09 - 14.20)mm)，右冠状动脉近端（RCA）为4.50±0.48mm和16.14±3.43mm，RCA中段为4.16±0.420mm和13.74±2.72mm，RCA远端为3.81±0.41mm和11.59±2.46mm。体表面积（BSA）是大多数心外膜冠状动脉的独立预测因素，呈正线性关系。
印度尼西亚人群的平均动脉大小与先前的研究相当。了解冠状动脉大小将有助于临床医生在进行干预时有所参考，尤其是在没有血管内成像的情况下。
