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)
The magnitude of the benefit of percutaneous transluminal coronary angioplasty (PTCA) in terms of quality of life depending on baseline and outcome clinical variables is not sufficiently understood because of the restrictive inclusion criteria of randomized clinical trials. The present study was designed to assess perceived health outcome at 3 years and its(More)
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)
OBJECTIVE The Short Form-36 Health Survey (SF-36) is one of the most widely used and evaluated generic health-related quality of life (HRQL) questionnaires. After almost a decade of use in Spain, the present article critically reviews the content and metric properties of the Spanish version, as well as its new developments. METHODS A review of indexed(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)
Review and pooled analysis of the relevant worldwide literature was investigated from 1975 to 1996. Eighteen surveys out of 54 were suitable for analysis according to the selection criteria. This represents a total of 60494 observations from 26 countries all over the world. Data suggests differences as great as 76 mg/dl when comparing northern European(More)
BACKGROUND The purpose of this study was to determine the independent value of left ventricular (LV) functional parameters derived from gated fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) to predict prognosis in patients with ischemic cardiomyopathy undergoing myocardial viability assessment. METHODS AND RESULTS We studied 90(More)
INTRODUCTION AND OBJECTIVES The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is the most commonly used instrument for evaluating quality of life in patients with heart failure. It comprises 21 items and two dimensions: the physical and the emotional. The aim of this study was to assess the psychometric properties of the Spanish version of the(More)
To validate the AHCPR classification for the prognosis of unstable angina, 225 consecutive patients were recruited with a suspected diagnosis of that condition attending a tertiary hospital from November 1994 through April 1995 and followed for one year. One-hundred fifty-six (69.3%) patients were considered at high risk, 37 (16.5%) at intermediate, and 32(More)
BACKGROUND The risk of selection bias in registries and its consequences are relatively unexplored. We sought to assess selection bias in a recent registry about acute coronary syndrome and to explore the way of conducting and reporting patient registries of acute coronary syndrome. METHODS AND RESULTS We analyzed data from patients of a national acute(More)
