摘　　要：目的应用MRI建立中国成人左心室肌小梁和乳头肌质量(TPMM)的正常参考值,并探索TPMM的影响因素。方法回顾性纳入168例中国健康成人,分别应用传统和精细方法测量致密和总左心室心肌质量(LVM)。TPMM由总LVM和致密LVM的差值获得。应用独立样本t检验和方差分析探索不同性别和年龄组TPMM的差异性,应用多元线性回归分析TPMM与年龄、性别、心率、收缩压(SBP)、空腹血糖(FBG)和体质量指数(BMI)的独立相关性。结果男性较女性TPMM显著较大(P<0.001);女性高年龄组TPMM显著较大(P<0.05),而男性各年龄组TPMM无显著性差异。多元线性回归表明BMI和SBP均与TPMM呈独立正相关,而女性和心率与TPMM呈独立负相关(P<0.05)。结论本研究按照性别和年龄分层建立的中国成人TPMM正常参考值中,性别、心率、BMI和SBP均与TPMM存在独立相关性。Objective To establish normal reference values for left ventricular trabecular and papillary muscle mass(TPMM)in Chinese adults using MRI and to explore its impact factors.Methods A total of 168 healthy Chinese adults were retrospectively included,and compacted and total left ventricular myocardial mass(LVM)were measured using traditional and dedicated methods,respectively.TPMM was calculated from the difference between total and compacted LVM.Independent sample t-tests and analysis of variance were used to explore the differences in TPMM among genders and age groups,while multiple linear regression was used to explore the independent correlation between TPMM and age,gender,heart rate,systolic blood pressure(SBP),fasting blood glucose(FBG),and body mass index(BMI).Results TPMM for men was significantly larger than that for female(P<0.001).TPMM in the elderly group was significantly larger in female(P<0.05),but not in men.Multiple linear regression showed that BMI and SBP were both independently positively correlated with TPMM,and female and heart rate were independently negatively correlated with TPMM(P<0.05).Conclusion This study provides ageand gender-specific normal reference values for TPMM in Chinese adults.Gender,heart rate,BMI,and SBP are all independently associated with TPMM.
