Abstract:
Objective To investigate the diagnostic value of 1.5T magnetic resonance imaging(MRI) in the left ventricular structure and cardiac function of the patients with primary dilated cardiomyopathy(IDCM).Methods Sixty-seven patients with ID-CM(IDCM group) in this hospital from January to December 2016 were selected and contemporaneous 45 healthy volunteers served as the control group.The left ventricular structure parameters[end diastolic diameter(EDD),end systolic diameter(ESD),densifying thickness (C),trabecular thickness (NC),interventricular septal basement thickness (IVS),short axis shortening rate (△D),wall thickening rate(△T)],and cardiac function status[left ventricular end diastolic blood volume(EDV),end-systolic blood volume (ESV),ejection fraction(EF),stroke volume(SV) and cardiac output(CO)] were analyzed in the two groups.Results The levels of NC,NC/C,IVS,EDD,ESD,TDD,ESV and EDV in the IDCM group were higher than those in the control group,while C,C/IVS,△D,△T,MM,TSD,CO,EF and SV were smaller than those in the control group,except for C and IVS,the difference in the intergroup comparison was statistically significant(P＜0.05).In the IDCM group,compared with the grade Ⅰ-Ⅱ,ESV and EDV in the grade Ⅲ and Ⅳ were cncreased,while SV,CO and EF decreased,the difference statistically significant(P＜0.05).With the grade increase and ESV and EDV values were increased,SV,CO and EF were decreased,the difference had statistical significance (P＜0.05).Conclusion MRI can early analyze the left ventricular structure parameters and cardiac function status in the patients with IDCM,and can pre-judge the heart function situation effectively and qualitatively.
