Dados preliminares têm demonstrado que o perfil
de segurança e eficácia do stent FirebirdTM é semelhante ao do
stent Cypher®. No entanto, até o presente momento, nenhum
estudo avaliou a intervenção coronária percutânea (ICP) com o
FirebirdTM em diabéticos. Métodos: Comparamos, em diabéticos
portadores de doença arterial coronária (DAC) multiarterial, o
desempenho do Firebird™ (n = 100) ao do Cypher®, utilizando os
dados históricos do estudo ARTS-II (n = 159). Foram comparados
os eventos cardiovasculares adversos maiores (ECAM) em um
ano. Resultados: A maioria dos pacientes do grupo FirebirdTM
era do sexo masculino (65%), com média de idade de 63,3
± 10,4 anos e 5% estavam em uso de insulina. Predominaram
os quadros clÃnicos estáveis (60%), 45% eram portadores de
DAC triarterial e a função ventricular era preservada (56,6
± 13,7%). Nos pacientes com DAC triarterial, foram tratadas
135 lesões, com 3 ou mais stents em 78% dos casos e 2
stents nos demais. Nos pacientes com DAC biarterial, foram
tratadas 110 lesões com 2 ou mais stents em 80% dos casos
e 1 stent nos demais. A incidência de ECAM em um ano do
Firebird™ foi de 21%, óbito ocorreu em 3% dos pacientes,
infarto do miocárdio em 2%, e novo procedimento de revascularização
miocárdica em 18%, predominantemente à custa
de nova ICP em 14% dos casos. A comparação com o grupo
Cypher® não mostrou diferenças para nenhum dos desfechos
avaliados. Conclusões: Em nosso estudo, o uso do stent
Firebirdâ„¢ apresentou resultados similares aos dos pacientes
do estudo ARTS-II, o que o torna atrativo para ser utilizado
no complexo cenário de pacientes diabéticos portadores de
DAC multiarterial.
Preliminary data have shown the FirebirdTM and
the Cypher® stents have similar safety and efficacy profiles.
However,
to date, no study has evaluated the percutaneous
coronary
intervention (PCI) with the FirebirdTM stent in diabetic
patients. Methods: The performance of the FirebirdTM stent
in diabetic patients with multivessel coronary artery disease
(CAD) (n = 100) was compared to that of the Cypher® stent,
using historical data from the ARTS-II study (n = 159). We
compared
the major adverse cardiovascular events (MACE) at
one year. Results: Most of the patients in the FirebirdTM group
were male (65%), with mean age of 63.3 ± 10.4 years and
5% were receiving insulin. Stable coronary syndromes were
prevalent (60%), 45% had three-vessel CAD and ventricular
function was preserved (56.6 ± 13.7%). In patients with threevessel
CAD, 135 lesions were treated with > 3 stents in 78%
of the cases and 2 stents in the remaining ones. In patients
with two-vessel CAD, 110 lesions were treated with > 2 stents
in 80% of the cases and 1 stent in the remaining ones. The
incidence of MACE at one year of the FirebirdTM stent was
21%, death was observed in 3% of the patients, myocardial
infarction
in 2% and a new revascularization procedure in
18%,
predominantly at the expense of a new PCI in 14% of
the cases. Comparison with the Cypher® group did not show
differences for any of the evaluated endpoints. Conclusions:
In our study, the use of the FirebirdTM stent showed similar
results to those of patients in the ARTS-II study, which makes
it attractive for use in the complex scenario of diabetic patients
with multivessel CAD.
