Through the multiple stepwise regression analysis, the duration of the disease and serum GH level were the main influencing factors of acromegalic cardiomyopathy. 2 Ejection fraction and fractional shortening, were decreased, compared to control group, they still remained in normal range. 3 Isovolumic relaxation time and E wave descending time, were delayed apparently compared to control group, indicating the damage of cardiac relaxation. 4 Subgroup analysis in acromegalic: The comparison between patients with diabetes mellitus and impaired glucose tolerance and patients without DM/IGT showed that there was no significant difference in terms of the parameters in the two groups, in spite of an mild increase of IVST in the former group.

经多元逐步回归分析，病程和血清生长激素浓度为心肌肥厚的主要影响因素。2实验组射血分数和左心室短轴缩短率虽较对照组低，但仍在正常范围。3实验组左心室等容舒张时间和二尖瓣减速时间较对照组明显延长。4实验组中继发糖尿病／糖耐量减低组与非DM/IGT组进行比较，前者仅室间隔有较明显增厚，其余各项参数2组间差异均无统计学意义。

The parameters showing left ventricular systolic function, such as ejection fraction and fractional shortening in acromegaly group were no significant difference, compared with those in control group.

反映心脏收缩功能的参数，射血分数和左室短轴缩短率，早期肢端肥大症患者与对照组比较无显著性差异。
