目的：利用双源CT探讨生理性心室肌脂肪化的影响因素。方法排除一些原发性心脏疾病共纳入887例受试者，将心室肌分为9个部位，对心肌进行脂肪化评分，同时记录每位患者的临床资料。并用相应的统计方法进行统计分析，p＜0.05差异有统计学意义。结果887例患者当中，有204(204/887，23.0%)例出现心室肌脂肪化，右心室心肌脂肪化发生率明显大于左心室(168/204,82.4%)。平均脂肪积分为2.7±3.2，生理性心肌脂肪化好发于女性(P＜0.0001)，年龄大于65岁(P=0.0109)、BMI≥25 kg/m2(P=0.0119)及高血压的患者(P=0.0135)。结论双源CT可以很好的探测到生理性脂肪化的心肌，女性、年龄≥65、BMI≥25、高血压是导致心室肌生理性脂肪化的主要因素。

Objective To study the related influential factors of physiological fatty change of ventricular muscle by dual-source computed tomography (CT). Methods 887 cases without primary heart diseases were enrolled. The ventricle muscle was divided into 9 parts, and the fatty change of ventricular muscle and clinical information of patients was scored and statistically analyzed by relative statistical method. p<0.05 was considered as the standard for judging statistically significant. Results We observed myocardial fatty change in 204(204/887,23.0%) patients. The muscle fatty change incidence of right ventricle was obviously higher than the left ventricle(168/204, 82.4%). The average fat score was 2.7±3.2. Physiological myocardial fatty change had a prediction to involve female(P<0.0001), more than 65 years old(P=0.0109), BMI ≥25(P=0.0119), and HBP patients(P=0.0135). Conclusion Physiological myocardial fatty change can be well detected by dual-source CT. The main factors of myocardial fatty change were female,≥65 years old, BMI≥25 and HBP.
