RESUMO
Resumo Fundamento A doença arterial coronariana (DAC) devido à isquemia miocárdica causa perda permanente de tecido cardíaco. Objetivos Nosso objetivo foi demonstrar o possível dano ao miocárdio em nível molecular através dos mecanismos de autofagia e apoptose em pacientes submetidos à cirurgia de revascularização miocárdica. Métodos Um grupo recebeu uma solução de cardioplegia Custodiol e o outro grupo uma solução de cardioplegia sanguínea. Duas amostras miocárdicas foram coletadas de cada paciente durante a operação, imediatamente antes da parada cardíaca e após a liberação do pinçamento aórtico. Foram avaliadas as expressões de marcadores de autofagia e apoptose. O nível de significância estatística adotado foi de 5%. Resultados A expressão do gene BECLIN foi significativa nos tecidos miocárdicos do grupo CS (p=0,0078). Os níveis de expressão dos genes CASPASE 3, 8 e 9 foram significativamente menores no grupo CC. Os níveis pós-operatórios de TnT foram significativamente diferentes entre os grupos (p=0,0072). As expressões dos genes CASPASE 8 e CASPASE 9 foram semelhantes antes e depois do pinçamento aórtico (p=0,8552, p=0,8891). No grupo CC, os níveis de expressão gênica de CASPASE 3, CASPASE 8 e CASPASE 9 não foram significativamente diferentes em amostras de tecido coletadas após pinçamento aórtico (p=0,7354, p=0,0758, p=0,4128, respectivamente). Conclusões Com nossos achados, acreditamos que as soluções CC e CS não apresentam diferença significativa em termos de proteção miocárdica durante as operações de by-pass.
ABSTRACT
Abstract Background Coronary artery disease (CAD) due to myocardial ischemia causes permanent loss of heart tissue. Objectives We aimed to demonstrate the possible damage to the myocardium at the molecular level through the mechanisms of autophagy and apoptosis in coronary bypass surgery patients. Methods One group was administered a Custodiol cardioplegia solution, and the other group was administered a Blood cardioplegia solution. Two myocardial samples were collected from each patient during the operation, just before cardiac arrest and after the aortic cross-clamp was released. The expressions of autophagy and apoptosis markers were evaluated. The level of statistical significance adopted was 5%. Results The expression of the BECLIN gene was significant in the myocardial tissues in the BC group (p=0.0078). CASPASE 3, 8, and 9 gene expression levels were significantly lower in the CC group. Postoperative TnT levels were significantly different between the groups (p=0.0072). CASPASE 8 and CASPASE 9 gene expressions were similar before and after aortic cross-clamping (p=0.8552, p=0.8891). In the CC group, CASPASE 3, CASPASE 8, and CASPASE 9 gene expression levels were not found to be significantly different in tissue samples taken after aortic cross-clamping (p=0.7354, p=0.0758, p=0.4128, respectively). Conclusions With our findings, we believe that CC and BC solutions do not have a significant difference in terms of myocardial protection during bypass operations.
