The objective of this research was to analyze and correlate the length of the left main coronary artery (LMCA) with significant clinical parameters using multi-slice CT (MSCT).
1500 patients (851 males and 649 females; mean age 57.38 ± 11.03 [SD]; age range: 5-85 years) who underwent MSCT scans from September 2020 to March 2022 were retrospectively included. The data were applied to generate three-dimensional (3D) simulations of a coronary tree using the syngo.via post-processing workstation. The reconstructed images were then interpreted, and the collected data were subjected to statistical analysis.
The results showed 1206 (80.4%) cases with medium LMCA, 133 (8.9%) with long LMCA, and 161 (10.7%) with short LMCA. The average diameter of LMCA at its midpoint was 4.69 ± 0.74 mm. The most frequent type of division of LMCA was bifurcation in 1076 (71.7%) cases; in 424 (28.3%) cases, the LMCA was divided into three or more branches. The dominance was right in 1339 (89.3%), left in 78 (5.2%), and co-dominant in 83 (5.5%) cases. There was a positive correlation between the length and branching patterns of LMCA, χ2 = 113.993, P = 0.000 (< 0.05). Other variables like age, sex, diameter of LMCA, and coronary dominance did not show any significant correlation.
This study has demonstrated a significant association between the length and the branching pattern of LMCA, which may be essential in diagnosing and treating coronary artery patients.
本研究旨在通过多层螺旋 CT（MSCT）分析和关联左主干冠状动脉（LMCA）的长度与显著的临床参数。
回顾性纳入 2020 年 9 月至 2022 年 3 月间进行 MSCT 扫描的 1500 例患者（851 名男性和 649 名女性；平均年龄 57.38±11.03[标准差]；年龄范围：5-85 岁）。应用该数据在 syngo.via 后处理工作站上生成冠状动脉树的三维（3D）模拟。然后对重建图像进行解释，并对收集的数据进行统计分析。
结果显示 1206 例（80.4%）为中等 LMCA，133 例（8.9%）为长 LMCA，161 例（10.7%）为短 LMCA。LMCA 中点的平均直径为 4.69±0.74mm。LMCA 最常见的分支类型为 1076 例（71.7%）的分叉；424 例（28.3%）的 LMCA分为三支或更多分支。右优势型 1339 例（89.3%），左优势型 78 例（5.2%），共同优势型 83 例（5.5%）。LMCA 的长度与分支模式之间存在正相关，χ2=113.993，P=0.000（<0.05）。其他变量如年龄、性别、LMCA 直径和冠状动脉优势与 LMCA 长度和分支模式无显著相关性。
本研究表明 LMCA 的长度与分支模式之间存在显著关联，这对于诊断和治疗冠状动脉患者可能至关重要。
