Resumo
Associations between periodontal disease (PD) and cardiovascular changes in dogs, such as infeccious endocarditis (IE), are reported by literature, although no evidences between them are verified. Anesthetic drugs, used for periodontal treatment (PT), can lead to hypotension, reduction of coronary blood flow and myocardial ischemia. Determination of biomarkers, especially cardiac troponin I (cTnI) can be used for the detection of myocardial injury in both cases: endocarditis and the effects of anesthetic drugs. This study aimed to evaluate canine cTnI in dogs with PD, as an indicator of IE, after PT, with and without using antibiotics. It was used 24 dogs with PD, with no evidence of any other systemic diseases. They were selected by physical examination, laboratory and cardiovascular evaluation and were divided into three groups: group I (n=8; control) - anesthetized dogs, group II (n=8) - anesthetized dogs submited to PT, not treated with antibiotics, group III (n=8) - anesthetized dogs submited to PT, treated with antibiotics. The dogs were sedated with acepromazine and meperidine, induced with propofol and maintained with isoflurane in oxygen. Canine cTnI dosages were taken immediately before and 24 hours after PT, using commercial kit (ELISA). Statistical analysis were performed by using "D'Agostino & Pearson" normality test, unpaired t test to compare two samples and Tukey´s post hoc test for multiple comparisons. All tests were performed at a level of significance of 0.05 No significant differences were found between groups or in different moments (p>0.05). It was concluded that there is no increased cTnI in dogs with PD after PT, treated or not with antibiotics, suggesting that there was no development of IE, and there is no increase in canine cTnI in healthy dogs anesthetized using this protocol.
