Cardiac magnetic resonance stress perfusion: A single-center study
Donato, P; Ferreira, MJ; Silva, V; Pinto, A; Caseiro-Alves, F; Providência, LAINTRODUCTION AND OBJECTIVES: Myocardial ischemia can be assessed with cardiac magnetic resonance perfusion imaging (MRPI). This study aimed to analyze the clinical utility of MRPI in the diagnosis of significant coronary artery disease. METHODS: Fifty-five patients were examined with a 1.5 T MR scanner (Siemens Symphony), with a first pass of 0.10 mmol/kg gadolinium chelate, at rest and during adenosine vasodil...
Consensus document on coding of cardiac magnetic resonance examinations in Port...
Ferreira, MA; Almeida, AG; Oliveira, L; Bettencourt, N; Marques, H; Matos, P; Abecasis, J; Abreu, J; Alpendurada, F; Botelho, A; Campos, P; Castela, SOne of the obstacles to more frequent and appropriate use of cardiac magnetic resonance (CMR) in Portugal has been the lack of specific codes that accurately describe these examinations as they are currently performed. In this consensus document, recommendations are made for updating and standardizing CMR codes in Portugal. Guidance on which techniques and codes should be used in the most common clinical scenar...

Ferreira, AM; Almeida, AG; Oliveira, L; Bettencourt, N; Marques, H; Matos, P; Abecasis, J; Abreu, J; Alpendurada, F; Botelho, A; Campos, P; Castela, SUm dos obstáculos a uma utilização mais frequente e apropriada da ressonância magnética cardíaca (RMC) em Portugal tem sido a ausência de códigos específicos que descrevam adequadamente os exames tal como são efetuados actualmente. Este documento de consenso fornece recomendações para a atualização e uniformização dos códigos empregues na RMC. São igualmente feitas recomendações quanto às técnicas e códigos a u...
CYP2C19*2 and prognosis after an acute coronary syndrome: Insights from a Portu...
Teixeira, R; Monteiro, P; Marques, G; Pego, J; Lourenço, M; Tavares, C; Reboredo, A; Monteiro, S; Gonçalves, F; Ferreira, MJ; Freitas, M; Ribeiro, GBACKGROUND: Clopidogrel requires oxidation dependent on the cytochrome P450 enzyme 2C19 (CYP2C19) to form its active metabolite. The importance of loss-of-function alleles (particularly CYP2C19*2, 681G>A) in poor platelet response to clopidogrel is well recognized. OBJECTIVE: To investigate the prevalence and prognostic impact of the CYP2C19*2 allele in a local acute coronary syndrome (ACS) population. METHOD...
Renal artery aneurysm: An endovascular treatment for a rare cause of hypertension
Moreira, N; Pêgo, M; Carvalheiro, V; Agostinho, A; Donato, P; Pego, J; Ferreira, MJ; Providência, LARenal artery aneurysms are a rare cause of secondary hypertension. Endovascular treatment with a polytetrafluoroethylene (PTFE)-coated stent can exclude aneurysms and treat hypertension. We report the case of a 23-year-old man with hypertension diagnosed three years earlier and in whom renal angiography revealed three aneurysms involving the right renal artery. A covered stent was implanted, resulting in succes...
Effects of lower limb strengthening on balance and function in persons who suff...
Fernandes, B; Batista, F; Beckert, P; Evangelista, I; Ferreira, MJ; Prates, L; Sérgio, JIntroduction - Cerebrovascular diseases, and among them, cerebral vascular accidents, are one of the main causes of morbidity and disability at European Union countries. Clinical framework resulting from these diseases include important limitations in functional ability of the these patients Postural control dysfunctions are one of the most common and devastating consequences of a stroke interfering with functi...
Left ventricular end diastolic pressure and acute coronary syndromes
Teixeira, R; Lourenço, C; Baptista, R; Jorge, E; Mendes, P; Saraiva, F; Monteiro, S; Monteiro, P; Ferreira, MJ; Freitas, M; Providência, LABACKGROUND: Data is lacking in the literature regarding the prognostic impact of left ventricular-end diastolic pressure (LVEDP) across acute coronary syndromes (ACS). OBJECTIVE: To assess LVEDP and its prognostic implications in ACS patients. METHODS: Prospective, longitudinal and continuous study of 1329 ACS patients from a single center between 2004 and 2006. Diastolic function was determined by LVEDP. Pop...
Knee muscle strength, balance and functional independence in persons with stroke
Fernandes, B; Batista, F; Beckert, P; Ivangelista, I; Ferreira, MJ; Prates, L; Sérgio, JPurpose: To investigate the relationship between knee muscle strength, balance and functional independence within the first month after stroke. Relevance: Cerebral vascular disease is one of the main causes of morbidity, disability and mortality in developed countries. Problems with movement control are frequent after stroke. Lower limb weakness and impaired balance are common problems that are related with the...
Pulmonary veno-occlusive disease: a case report
Teixeira, R; Castro, G; Carvalho, L; Marinho da Silva, A; Monteiro, P; Ferreira, MJ; Providência, LAThe authors present the case of a 22-year-old female patient, white, referred to the cardiovascular outpatient clinic in November 2006 for pulmonary arterial hypertension. Complementary diagnostic exams revealed elevated pulmonary arterial pressure, normal capillary wedge pressure and a reduced cardiac index on invasive hemodynamic study. A high-resolution pulmonary CT scan identified a diffuse ground-glass opa...
A Importância de um ECG Normal em Síndromes Coronarianas Agudas sem Supradesniv...
Teixeira, R; Lourenço, C; António, N; Monteiro, S; Baptista, R; Jorge, E; Ferreira, MJ; Monteiro, P; Freitas, M; Providência, LABACKGROUND: Admission ECG has a major impact on the diagnosis and management of non-ST elevation acute coronary syndromes (ACS). OBJECTIVE: To assess the impact of the admission ECG on prognosis over non-ST ACS. Population: prospective, continuous, observational study of 802 non-ST ACS patients from a single center. METHODS: Patients were divided in 2 groups: A (n=538) - Abnormal ECG and B (n=264) - Normal ECG....
