ABSTRACT
Abstract

Background:

There are sparse data on the performance of different types of drug-eluting stents (DES) in acute and real-life setting.

Objective:

The aim of the study was to compare the safety and efficacy of first- versus second-generation DES in patients with acute coronary syndromes (ACS).

Methods:

This all-comer registry enrolled consecutive patients diagnosed with ACS and treated with percutaneous coronary intervention with the implantation of first- or second-generation DES in one-year follow-up. The primary efficacy endpoint was defined as major adverse cardiac and cerebrovascular event (MACCE), a composite of all-cause death, nonfatal myocardial infarction, target-vessel revascularization and stroke. The primary safety outcome was definite stent thrombosis (ST) at one year.

Results:

From the total of 1916 patients enrolled into the registry, 1328 patients were diagnosed with ACS. Of them, 426 were treated with first- and 902 with second-generation DES. There was no significant difference in the incidence of MACCE between two types of DES at one year. The rate of acute and subacute ST was higher in first- vs. second-generation DES (1.6% vs. 0.1%, p < 0.001, and 1.2% vs. 0.2%, p = 0.025, respectively), but there was no difference regarding late ST (0.7% vs. 0.2%, respectively, p = 0.18) and gastrointestinal bleeding (2.1% vs. 1.1%, p = 0.21). In Cox regression, first-generation DES was an independent predictor for cumulative ST (HR 3.29 [1.30-8.31], p = 0.01).

Conclusions:

In an all-comer registry of ACS, the one-year rate of MACCE was comparable in groups treated with first- and second-generation DES. The use of first-generation DES was associated with higher rates of acute and subacute ST and was an independent predictor of cumulative ST.
RESUMO
Resumo Fundamento Os dados sobre o desempenho dos diferentes tipos de stents farmacológicos (SF) no cenário agudo e da vida real são escassos.

Objetivo:

Comparar a segurança e a eficácia dos SF de primeira e de segunda geração em pacientes com síndrome coronariana aguda (SCA).

Métodos:

Este registro arrolou pacientes consecutivos com diagnóstico de SCA e tratados com intervenção coronariana percutânea e implantação de SF de primeira ou segunda geração em seguimento de 1 ano. O desfecho primário 'eficácia' foi definido como eventos cardíacos adversos maiores (ECAM), um composto de morte por todas as causas, infarto do miocárdio não fatal, revascularização de vaso-alvo e acidente vascular encefálico. O desfecho primário 'segurança' foi trombose de stent (TS) definitiva em 1 ano.

Resultados:

Do total de 1.916 pacientes arrolados, 1.328 foram diagnosticados com SCA. Desses, 426 foram tratados com SF de primeira geração e 902, com SF de segunda geração. Não houve diferença significativa na incidência de ECAM entre os dois tipos de SF em 1 ano. A taxa de TS aguda e subaguda foi maior com SF de primeira geração do que com os de segunda geração (1,6% vs. 0,1%, p < 0,001; e 1,2% vs. 0,2%, p = 0,025, respectivamente), mas não houve diferença para TS tardia (0,7% vs. 0,2%, respectivamente, p = 0,18) nem para sangramento gastrointestinal (2,1% vs.1,1%, p = 0,21). Na regressão de Cox, o SF de primeira geração foi preditor independente para TS cumulativa [HR 3,29 (1,30-8,31); p = 0,01].

Conclusões:

No registro de SCA, a taxa de ECAM em 1 ano foi comparável nos grupos tratados com SF de primeira e de segunda geração. O uso de SF de primeira geração associou-se a maiores taxas de TS aguda e subaguda, sendo um preditor independente para TS cumulativa.
