目的分析健康体检人群左室重量指数(LVMI)的相关因素。方法健康体检者968例分为两组:A组,857例,LVMI正常(男性LVMI<125g/m~2,女性LVMI<120g/m~2);B组,111例,LVMI超重(男性LVMI>125g/m~2,女性LVMI>120g/m~2)。比较两组BMI、SBP、DBP、HDL-C、LDL-C、TC、TG、FBG、肌酐(Cr)、尿素氮(BUN)、尿酸(UA)、左室射血分数(LVEF)等检测结果。结果 18~39岁体检者LVMI超重率低于40~59岁体检者(P<0.01);≥60岁体检者LVMI超重率高于40~59岁体检者(P<0.01)。A组SBP、LDL-C、TC、TG、Cr低于B组(P<0.01);A组LVEF高于B组(P<0.01)。多因素Logistic回归分析显示,高血压病和高脂血症是LVMI超重的独立危险因素(P<0.05)。结论 LVMI与高血压病和高脂血症密切相关;应重视LVMI对心功能的影响。
Objective To analyze the related factors of left ventricular mass index (LVMI) in healthy physical examination population. Methods A total of 968 healthy subjects were divided into two groups: group A (n = 857), normal LVMI (LVMI <125g / m 2, LVMI 120g / m 2) > 125g / m ~ 2, female LVMI> 120g / m ~ 2). The results of BMI, SBP, DBP, HDL-C, LDL-C, TC, TG, FBG, Cr, BUN, UA and LVEF were compared between the two groups . Results The LVMI overweight rate of 18-39 year-olds was lower than that of 40-59-year-olds (P <0.01). The overweight rate of LVMI in ≥60-year-olds was higher than that of 40- 59s (P <0.01). The SBP, LDL-C, TC, TG and Cr in group A were lower than those in group B (P <0.01). The LVEF in group A was higher than that in group B (P <0.01). Multivariate Logistic regression analysis showed that hypertension and hyperlipidemia were independent risk factors of LVMI overweight (P <0.05). Conclusion LVMI is closely related to hypertension and hyperlipidemia; the influence of LVMI on cardiac function should be emphasized.
