Heart stiffing due to dilated cardiomyopathy in pediatric population and causes of its severity
Heart stiffing and dilated cardiomyopathy
,
Abstract
study was aimed to assess the possible changes in heart stiffing due to dilated cardiomyopathy and causes of severity in pediatric population.
Methods
Forty-eight children who had DCM and 96 healthy children were the subjects of this case-control study. The patients had an echocardiography determination of enlarged cardiomyopathy and healthy children were chosen randomly from the individuals who had alluded to the cardiac clinic for yearly examination. M-mode echocardiography was used to measure the ascending aorta's systolic and diastolic diameters, and modified Ross classification was used to classify heart failure. The Statistical Package for the Social Sciences, version 18 (SPSS, Chicago, USA), was used for statistical analysis. The level of statistical significance was set at p less than 0.05.
Results
Of children 48 had DCM and 96 were healthy, were matched in gender (X2=0.014, p=0.905). The parameters of EF (P<0.001), FS (P<0.001), IVSD (P<0.001), PWD (P<0.001), PWS (P<0.001), LVMI (P<0.001), RWT (P=0.009), AS (p=0.014). AD (p=0.004), ASBI (p=0.001) and PSEM (p=0.004) were different in groups significantly. After treatment, based on the EF and FS cutoffs none of elasticity parameters changed except ASβI that changed by ROSS classification.
Conclusion
Concluded that AS, AD decreased when ASBI and PSEM were increased in DCM children. EF, FS status and ROSS classifications were improved after treatment. The elasticity parameters preserved their status based on status of EF, FS and ROSS except ASβI that increased by changes in ROSS classification.
