Application of echocardiography Z score in pediatric dilated cardiomyopathy / 中国医学影像技术

ABSTRACT

The children with dilated cardiomyopathy (DCM) are in the different stages of growth and development,so the measurements of the cardiac size and the function in the echocardiography can change with those growth and development.But the influence factors of growth and development had been ignored by the previous standards,which was not conducive to evaluate the efficacy of drugs and the prognosis of patients.The disadvantages above can be overcome by converting the echocardiographic measurements into the Z score after correction of the body surface area.With the development of the ultrasonic technology,there have been some studies of the Z score combined with the ultrasound to assess the left/right ventricular heart function and prognosis in children with dilated cardiomyopathy.The progresses of Z score in children with dilated cardiomyopathy were reviewed in this article.
