The Significance Of The Peripheral Blood T-lymphocyte CD₄～+/CD₈～+ Ratio In The Patients With Recent-onset Dilated Cardiomyopathy And The Research On The Correlation Of The CD₄～+/CD₈～+ Ratio And Left Vent

Objective: To study the levels of immune function of the patients with recent-onset(≤6 months of symptoms) dilated cardiomyopathy by measuring the peripheral blood T-lymphocyte CD4+/CD8+ ratio and to analyze the correlation of the CD4+/CD8+ ratio and left ventricular ejection fraction.Methods: Twenty-five patients with recent-onset dilated cardiomyopathy and twenty-two healthy donors entered this study. They were divided into dilated cardiomyopathy group (to be called DCM group for short) and normal control group. The DCM group included 16 male and 9 female (age 28~68 years, mean age 51.68±10.23 years).The control group composed of 15 male and 7 female (age 29~67 years, mean age 49.36±10.75 years).2ml venous blood sample was collected in morning in everyone and then the T-lymphocyte CD4+/CD8+ ratio was measured by...
