Evaluation of left ventricular global function in healthy young and middle-aged people with MSCT during coronary CTA
Abstract：Objective To setup the normal range of left ventricular ( LV) global function parameters in healthy young and middle-aged people,and to explore the relationship between the gender ,age,body mass index(BMI)and LV global function parameters .All these cases did not detect any abnormalities about coronary and heart when having coronary artery CTA with 256 slice CT.Methods To the 410 normal cases, end-diastolic volume ( EDV), end-systolic volume ( ESV), stroke volume(SV),ejection fraction(EF),cardiac output(CO), myocardial mass(MM),end-diastolic volume index(EDVI), end-systolic volume index(ESVI),stroke volume index(SVI),cardiac output index(CI),myocardial mass index(MMI) were measured .The difference of the parameters between the two genders ,the relationship between the LV global function parameters and BMI,age were evaluated.Resu lts The normal range of left ventricular ( LV) global function are:male,ESV47.10 ~55.33ml,EDV143.15~154.56ml ,SV 94.49~102.96ml,CO 6162.59~6734.39ml/min,MM 129.78~146.00g,EF 64.17~67.69%.Female:ESV 39.62~45.33ml,EDV 126.49~136.26ml,SV 85.43~92.35ml,CI 5590.52~6129.45ml/min, MM 101.98~113.87g,EF 65.87%~69.00%.EDV,ESV,SV,CO,MM in male group are significantly higher than those in female group( P <0.05).Wheras,for the standardized parameters,only MMI in male group is larger than that in female group ( P <0.05).There is no correlation between BMI and EF ( P =0.194),while there are definitive correlation between BMI and EDV,ESV,SV,CO,MM ( P =0.002,0.000,0.000,0.038,0 .000, r =0.293,0.424,0.335,0.199,0.482 ).After standardization,only MMI is correlated with BMI,( P =0.04, r =0.276).Age is significantly correlated with ESV and EDV ( P =0.017,0.003,r =-0.362,-0.436) before standardization.But,after standardization,there is no correlation between the age and all parameters .Conclusion It is convenience to get the normal range of left ventricular ( LV) global function parameters in healthy young and middle-aged people when having coronary CTA with 256-slice CT.There is certain correlation between these parameters and genders ,age,as well as BMI .
