ABSTRACT

OBJETIVO: Avaliar a evolução clínica de pacientes submetidos a transplante de rim, portadores de doença arterial coronariana, que foram tratados com implante de stent coronariano (ATC-ST). MÉTODOS: Entre julho de 1998 e novembro de 2004, foram realizados, no total, 3.334 transplantes de rim em nossa Instituição (Hospital do Rim e Hipertensão). Desse total, 33 pacientes previamente submetidos a transplante de rim fizeram ATC-ST para o tratamento de 62 estenoses graves em 54 artérias coronárias, nos quais foi realizada análise retrospectiva. O registro dos eventos clínicos foi feito por meio de análise do prontuário médico, consulta médica e ligações telefônicas. RESULTADOS: No seguimento clínico de 30 meses, após a ATC-ST, observou-se que 67 por cento dos pacientes permaneceram assintomáticos, 18 por cento dos pacientes apresentaram quadro de angina estável, 6 por cento apresentaram síndrome coronariana aguda sem supra de ST e 3 por cento apresentaram síndrome coronariana aguda com supra de ST. Não houve pacientes com acidente vascular cerebral, insuficiência cardíaca congestiva ou morte cardíaca. Houve três mortes não-cardíacas. Foi observado índice de reestenose de 9 por cento, que é comparável ao dos estudos de stent farmacológico. CONCLUSÃO: Concluímos que pacientes submetidos a transplante de rim que desenvolveram doença arterial coronariana e que foram tratados com stent coronariano tiveram baixo porcentual de reestenose clínica, provavelmente relacionado ao regime de imunossupressão administrado para evitar rejeição renal.


OBJECTIVE: To assess the clinical outcome of renal transplant patients who developed coronary artery disease and were treated with coronary stenting (TCA-ST). METHODS: A total of 3,334 renal transplants were performed in our service - Hospital do Rim e Hipertensão - HRH (Kidney and Hypertension Hospital) from July, 1998 to November, 2004. During this period, 33 of the renal transplant patients underwent TCA-ST to treat 62 severe stenoses in 54 coronary arteries. A retrospective analysis was performed with renal transplant patients undergoing TCA-ST at HRH. The clinical events were registered using medical charts, medical visits and phone calls. RESULTS: During the 30-month clinical follow-up after TCA-ST, 67 percent of the patients remained asymptomatic, 18 percent presented stable angina, 6 percent presented acute coronary syndrome without ST-segment elevation (ACSWSTE), and 3 percent presented acute coronary syndrome with ST-segment elevation (ACSSTE). No strokes, CHF or cardiac deaths were observed. Three non-cardiac deaths occurred. A restenosis rate of 9 percent was observed, which is comparable to those found in studies on drug-eluting stents. CONCLUSION: In conclusion, renal transplant patients who developed CAD and were treated with coronary stenting had a low rate of in-stent restenosis, probably related to the immunosuppressive regimen given to prevent kidney rejection.

O registro dos eventos clínicos foi feito por meio de análise do prontuário médico, consulta médica e ligações telefônicas. Resultados: No seguimento clínico de 30 meses, após a ATC-ST, observouse que 64% dos pacientes permaneceram assintomáticos, 18% dos pacientes apresentaram quadro de angina estável, 6% apresentaram síndrome coronariana aguda sem supra de ST e 3% apresentaram síndrome coronariana aguda com supra de ST. Houve três (9%) mortes não cardíacas. Não houve pacientes com acidente vascular cerebral, insuficiência cardíaca congestiva ou morte cardíaca. Foi observado índice de reestenose de 9%, o qual é comparável aos estudos de stent farmacológico. Conclusão: Concluímos que pacientes submetidos a transplante de rim, que desenvolveram doença arterial coronariana e que foram tratados com stent coronário, tiveram baixo porcentual de reestenose clínica, provavelmente relacionado ao regime de imunossupressão administrado para evitar a rejeição renal.
