Abstract:
Objective: To explore the relationship between plasma levels of calcitonin gene related peptide (CGRP) and cardiac function in ventricular septal defect (VSD) children before and after the interventional therapy.
Methods: Our research included 2 groups:VSD group, n=90 containing 43 male and 47 female at the age of (3-12) years and treated in our hospital from 2011-09 to 2012-09, Control group, n=50 healthy children with matched age and gender. The levels CGRP were measured at before and 24 hours, 3 days, 5 days, 3 months after the therapy. The cardiac function as left ventricle end-diastolic diameter (LVEDD), left ventricle end systolic diameter (LVESD), left ventricle end diastolic volume (LVEDV), left ventricle end systolic volume (LVESV) and ejection fraction (EF) were examined by echocardiography at before and after the procedure.
Results: Before interventional procedure, the level of CGRP in VSD group was lower than Control group (35.28 ± 7.25) pg/ml vs (50.90 ± 8.60) pg/ml, t=11.42, P<0.01. In VSD group, the post-procedural levels of CGRP were increased at all time points, the highest level was at 24 hours and the descending started at 3 days after procedure;the levels of CGRP at before and 24 hours, 3 days, 5 days after the procedure were different as (35.28 ± 7.25) pg/ml vs (102.03 ± 11.73) pg/ml, (35.28 ± 7.25) pg/ml vs (93.36 ± 9.12) pg/ml, (35.28 ± 7.25) pg/ml vs (87.91 ± 8.54) pg/ml, t=27.03, 26.93, 24.51, all P<0.01. In VSD group, the LVEDD, LVESD, LVEDV and LVESV decreased gradually at 5 days, 3 months and 6 months after the procedure;the levels of CGRP were signiifcantly related to LVEDD, LVESD, LVEDV, LVESV at before and 5 days, 3 months after the procedure, all P<0.05.
Conclusion: Plasma levels of CGRP closely related to ventricular cavity diameter, which was important for evaluating the cardiac function in VSD children after the interventional therapy.
