The length of the left main coronary artery (LMA) was determined in post-mortem, non-fixed hearts of normal weight (heart weight less than 400 g, group I) and hypertrophic hearts (heart weight greater than or equal to 400 g, group II). Hearts from 76 men and 88 women in group I and 136 men and 61 women in group II were studied. The mean length of LMA in group I was 9.1 mm in men and 8.4 mm in women. Corresponding values in group II were 10.3 mm and 8.8 mm. There was no significant sex difference in the length of LMA in group I, but the sex difference in group II was significant (p less than 0.01). The difference in length of LMA between groups I and II reveals that the difference in men was significant ( less than 0.02), but insignificant in women. In the case of both sexes no significant correlation between heart weight and the length of LMA was found either in group I or group II. There was a significant correlation between the area of the left coronary ostium and the length of LMA in men in group I (p less than 0.05), but not in women. Corresponding comparisons of both sexes in group II were statistically insignificant.
在正常体重（心脏重量小于400克，I组）和肥厚性心脏（心脏重量大于或等于400克，II组）的尸检非固定心脏中测定左冠状动脉主干（LMA）的长度。研究了I组的76名男性和88名女性以及II组的136名男性和61名女性的心脏。I组男性LMA的平均长度为9.1毫米，女性为8.4毫米。II组的相应值为10.3毫米和8.8毫米。I组LMA长度在性别上无显著差异，但II组的性别差异显著（p小于0.01）。I组和II组之间LMA长度的差异表明，男性之间的差异显著（小于0.02），而女性之间不显著。在I组和II组中，无论男女，均未发现心脏重量与LMA长度之间存在显著相关性。I组男性中，左冠状动脉口面积与LMA长度之间存在显著相关性（p小于0.05），但女性中不存在。II组中两性的相应比较在统计学上无显著意义。
