BACKGROUND Predictors of antiplatelet therapy discontinuation (ATD) during the first year after drug-eluting stent implantation are poorly known. METHODS AND RESULTS This was a prospective study with 3-, 6-, 9-, and 12-month follow-up of patients receiving at least 1 drug-eluting stent between January and April 2008 in 29 hospitals. Individual- and(More)
BACKGROUND Patent false lumen in aortic dissection has been associated with poor prognosis. We aimed to assess the natural evolution of this condition and predictive factors. METHODS AND RESULTS One hundred eighty-four consecutive patients, 108 surgically treated type A and 76 medically treated type B, were discharged after an acute aortic dissection with(More)
OBJECTIVES The goal of this study was to assess the risk associated with double antiplatelet therapy (DAT) discontinuation, and specifically, temporary discontinuation, during the first year after drug-eluting stent (DES) implantation. BACKGROUND Doubts remain about the risk of temporary DAT discontinuation within 1 year after DES implantation. METHODS(More)
BACKGROUND AND PURPOSE We sought to assess outcomes after endovascular treatment/therapy of acute ischemic stroke, overall and by subgroups, and looked for predictors of outcome. METHODS We used data from a mandatory, population-based registry that includes external monitoring of completeness, which assesses reperfusion therapies for consecutive patients(More)
BACKGROUND AND PURPOSE From 2006, the Stroke Code system operates throughout Catalonia with full coverage. The objective of this study was to determine safety and effectiveness of intravenous thrombolysis in routine practice through a monitored study (Catalan Stroke Code and Thrombolysis [Cat-SCT]) and to assess outcomes according to hospitals' previous(More)
BACKGROUND AND PURPOSE To investigate the 30-day and 12-month mortality risks among hospitalized stroke patients according to compliance with guideline-based process indicators. METHODS We used data from the Second Stroke Audit and the Mortality Register of Catalonia (Spain). The audit retrospectively explored quality of stroke care based on compliance(More)
BACKGROUND Different factors may weight on time from stroke onset to hospital arrival, and patients' alert certainly contributes to it. We sought to identify clinical and sociodemographic factors associated with a delayed alert and to delineate the profile of the potential latecomer in Catalonia (Spain). METHODS We used data from the Stroke Code (SC)(More)
AIMS To assess the benefit of off-pump coronary surgery stratified by the pre-operative risk profile. METHODS AND RESULTS Prospective and multicentric cohort study. All consecutive patients undergoing a first coronary bypass procedure between November 2001 and November 2003 were potentially eligible. Pre-operative EuroSCORE and in-hospital outcomes were(More)
Although composite endpoints (CE) are common in clinical trials, the impact of the relationship between the components of a binary CE on the sample size requirement (SSR) has not been addressed. We performed a computational study considering 2 treatments and a CE with 2 components: the relevant endpoint (RE) and the additional endpoint (AE). We assessed the(More)
INTRODUCTION AND OBJECTIVES Little is known about the long-term outcomes of coronary surgery and their determinants in Spain. The objectives of this study were to evaluate clinical outcomes, quality of life and survival in a cohort of patients 5 years after undergoing a first aortocoronary bypass operation without any other associated procedure. METHODS(More)
