Abstract
Troponin I concentration (cTnI) trend was analysed in 10 dogs undergoing the correction of patent ducts arteriosus (PDA). In 7 dogs an increased cTnI level within 24 hours from PDA closure was detected.It suggests that acute variation in left ventricle and aorta pressure and a left ventricle preload reduction, could damage myocardial cells and could cause cTnI release as consequence. cTnI was within normal values in 2 dogs, in 1 dog the highest level was found after 48 hour from PDA closure. Four dogs have already concluded the follow-up (6 months), normal cTnI levels were founded.File | Dimensione | Formato | |
