A report on a survey among Portuguese Association of Interventional Cardiology ...

Introduction and objectives: Concerns surrounding the consequences of ionizing radiation (IR) have increased in interventional cardiology (IC). Despite this, the ever-growing complexity of diseases as well as procedures can lead to greater exposure to radiation. The aim of this survey, led by Portuguese Association of Interventional Cardiology (APIC), was to evaluate the level of awareness and current practices...

The association of collaterals with myocardial ischemia and viability in chroni...

Collateral development in chronic total occlusions (CTO) is crucial to perfuse the distal myocardium and its angiographic evaluation is frequently used to assess the need for revascularization. We aimed to analyse the association between the presence of ischemia and hibernating myocardium, evaluated by cardiac [13 N]NH3/2-[18 F]FDG PET-CT, and the angiographic characterization of the collateral circulation. Pro...

Usefulness of Routine Fractional Flow Reserve for Clinical Management of Corona...

Importance: Approximately one-third of patients considered for coronary revascularization have diabetes, which is a major determinant of clinical outcomes, often influencing the choice of the revascularization strategy. The usefulness of fractional flow reserve (FFR) to guide treatment in this population is understudied and has been questioned. Objective: To evaluate the usefulness and rate of major adverse car...

Symptomatic bilateral coronary artery fistula to pulmonary artery in elderly pa...

We report the imaging findings of an uncommon coronary vascular termination anomaly, with fistula to the pulmonary artery. This 70 year old female patient presented unstable angina, showing a coronary artery fistula depicted in coronary angiogram from the left coronary to the pulmonary artery, with no significant atherosclerotic pathology. Due to development of ventricular tachycardia in stress echocardiogram e...

Predictors of pulmonary hypertension after intermediate-to-high risk pulmonary ...

Introdução: A tromboembolia pulmonar (TEP) é uma emergência cardiovascular comum que, juntamente com a hipertensão pulmonar tromboembólica crónica (HPTEC), se associa a alta mortalidade e morbilidade. Não há ainda consenso quanto à consecutividade destas patologias. Este estudo pretende determinar a incidência e fatores de risco para o desenvolvimento de hipertensão pulmonar (HTP) após uma TEP de risco interméd...

Digoxin in advanced heart failure patients: a question of rhythm

Background: The impact of digoxin on outcomes of patients with advanced heart failure (HF) remains uncertain and its effect may be different for patients in atrial fibrillation (AF) or sinus rhythm (SR). Objectives: To determine the impact of digoxin on outcomes of advanced HF patients and to assess whether prognosis differs in patients in AF and SR. Methods: A total of 268 consecutive patients admitted to an i...

One-shot diagnostic and prognostic assessment in intermediate- to high-risk acu...

Introduction: Contrast-enhanced multidetector computed tomography (MDCT) is useful for the diagnosis of pulmonary embolism (PE). However, current guidelines do not support its use for risk assessment in acute PE patients. Objectives: We compared the prognostic impact of MDCT-derived indices regarding mediumterm mortality in a population of intermediate- to high-risk PE patients, mostly treated by thrombolysis. ...

Anticoagulation in elderly patients with atrial fibrillation: from the guidelin...

Atrial fibrillation (AF) is a common medical problem with increasing prevalence among the elderly. Warfarin is effective in the prevention of AF-related-stroke but is often underutilized, especially in high-risk populations, like the elderly.To determine, in a group of elderly patients with AF, if those treated in-line with the clinical recommendations differ from patients who were not, regarding morbidity and ...

Estratégia invasiva em síndromes coronárias agudas sem supradesnivelamento de S...

Introdução: A idade é um importante factor prognóstico em contexto de síndromes coronárias agudas (SCA). A estratégia invasiva tem demonstrado benefício em muitas populações com SCA sem supradesnivelamento de ST; contudo, continua a ser um tema controverso em doentes mais susceptíveis a complicações relacionadas com o procedimento, como os idosos, uma população sub-representada nos estudos sobre a matéria. Obje...
