Estimating glomerular filtration rate in acute coronary syndromes: Different eq...
Almeida, I; Caetano, F; Barra, S; Madeira, M; Mota, P; Leitão-Marques, AAIMS: Renal dysfunction is a powerful predictor of adverse outcomes in patients hospitalized for acute coronary syndrome. Three new glomerular filtration rate (GFR) estimating equations recently emerged, based on serum creatinine (CKD-EPIcreat), serum cystatin C (CKD-EPIcyst) or a combination of both (CKD-EPIcreat/cyst), and they are currently recommended to confirm the presence of renal dysfunction. Our aim wa...
Implantable cardioverter-defibrillators in the elderly: rationale and specific ...
Barra, S; Providência, R; Paiva, L; Heck, P; Agarwal, SDespite the increasingly high rate of implantation of cardioverter-defibrillators (ICD) in elderly patients, data supporting their clinical and cost-effectiveness in this age stratum are ambiguous and contradictory. We comprehensively reviewed the state-of-the-art data regarding the applicability, safety, clinical- and cost-effectiveness of the ICD in elderly patients, and analysed which patients in this age st...
Meta-analysis of the influence of chronic kidney disease on the risk of thrombo...
Providência, R; Marijon, E; Boveda, S; Barra, S; Narayanan, K; Le Heuzey, JY; Gersh, BJ; Gonçalves, LChronic kidney disease (CKD) and atrial fibrillation (AF) frequently coexist. However, the extent to which CKD increases the risk of thromboembolism in patients with nonvalvular AF and the benefits of anticoagulation in this group remain unclear. We addressed the role of CKD in the prediction of thromboembolic events and the impact of anticoagulation using a meta-analysis method. Data sources included MEDLINE, ...
Can cardiac computed tomography predict cardiovascular events in asymptomatic t...
Faustino, A; Providência, R; Mota, P; Barra, S; Silva, J; Fernandes, A; Catarino, R; Basso, S; Costa, M; Leitão-Marques, ABACKGROUND: Doubts remain about atherosclerotic disease and risk stratification of asymptomatic type-2 diabetic patients (T2DP). This study aims to evaluate the usefulness of calcium score (CS) and coronary computed tomography (CT) angiography (CTA) to predict fatal and non fatal cardiovascular events (CVEV) in T2DP. METHODS: Eighty-five consecutive T2DP undergoing CT (Phillips Brilliance, 16-slice) with CS and...
Improving risk stratification in non-ST-segment elevation myocardial infarction...
Paiva, L; Providência, R; Barra, S; Dinis, P; Faustino, AC; Costa, M; Gonçalves, LBACKGROUND: Risk assessment is fundamental in the management of acute coronary syndromes (ACS), enabling estimation of prognosis. AIMS: To evaluate whether the combined use of GRACE and CRUSADE risk stratification schemes in patients with myocardial infarction outperforms each of the scores individually in terms of mortality and haemorrhagic risk prediction. METHODS: Observational retrospective single-centre co...
Overview of resistant hypertension: A glimpse of the cardiologist's current sta...
Paiva, L; Cachulo, MC; Providência, R; Barra, S; Dinis, P; Leitão-Marques, AHypertension is a major risk factor for cardiovascular disease, resulting in increased incidence of cerebrovascular events, ischaemic heart disease, heart failure, and renal impairment. Thus, it is one of the most important preventable causes of premature morbidity and mortality. Despite current knowledge on the management of hypertension and the availability of several effective antihypertensive medications, u...
