[Long-term clinical and angiographic follow-up of drug-eluting stents in patients with ST-elevation acute myocardial infarction].

Introduction And Objectives: Drug-eluting stents (DES) have proven to be effective in reducing the rate of restenosis and have, therefore, been incorporated into the treatment of patients with ST-elevation acute myocardial infarction (STEMI). The aim of this study was to investigate long-term clinical and angiographic outcomes following the use of DESs in patients with STEMI.

Methods: A prospective study involving clinical and angiographic follow-up was performed in 81 patients with STEMI who underwent percutaneous coronary intervention including DES implantation.

[Stent thrombosis in the modern era: incidence, outcome and predictive factors].

Coronary stent thrombosis is a catastrophic complication of percutaneous coronary intervention. Its incidence is reported to be about 1%, though it can occur more frequently in high-risk patients, in high-risk lesions, and in multivessel procedures. We investigated the occurrence of stent thrombosis in 404 consecutive patients in a period when conventional and drug-eluting stents were both being used.

[Prognostic value of persistent ST-segment elevation after successful primary angioplasty].

Introduction And Objectives: A variable percentage of patients with myocardial infarction treated with successful primary angioplasty and restoration of coronary flow show persistent ST-segment elevation, probably due to inadequate cellular reperfusion. We studied if persistent ST-segment elevation was a predictor of worse prognosis.

Patients And Methods: We comparatively studied the clinical and angiographic results of 116 acute myocardial infarction patients after successful primary angioplasty, which were classified into two groups depending on the persistence (> 50%) or reduction ( View Article and Find Full Text PDF
