Aneurysmal dilation of the coronaries arteries has a prevalence rate between 1-3% (1). It can be classified in aneurism or ectasia. The first, defined as a focal dilation of about 1.5x the normal diameter and the second as a diffuse dilation The right coronary is the most targeted with 40% of cases, foll...
BACKGROUND: Percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation is a widely adopted strategy for the treatment of de novo coronary artery disease. DES implantation conveys an inherent risk for short- and long-term complications, including in-stent restenosis and stent thro...
ABSTRACT: TREML4 and other members of the triggering receptor expressed in the myeloid cell family are associated with a risk of atherosclerosis and progression in coronary artery disease, acute coronary syndrome, and coronary artery calcification. Herein, the relationship between TREML4 expression and i...

INTRODUÇÃO: A intervenção coronária percutânea (ICP) no tronco da coronária esquerda (TCE) não protegido tem sido extensamente estudada nos últimos anos. Com o avanço tecnológico e técnico, e baseada nas evidências científicas mais recentes, tal procedimento é atualmente indicada como uma ...
INTRODUÇÃO: Imagem intravascular é de grande valia na avaliação de estenoses ambíguas e para guiar procedimentos de intervenção coronária percutânea (ICP) no tronco da coronária esquerda (TCE). A necessidade de injeção de contraste para remoção transitória do sangue intraluminal e o grand...
INTRODUCTION The occurrence of syncope is associated with increased mortality in patients with left bundle branch block (LBBB). Among syncope risk scores, it is consensual that electrocardiographic (ECG) abnormalities and the presence of underlying cardiac disease are prominent factors. However, there is...

INTRODUÇÃO: A compressão extrínseca de coronárias (CEXC) é causa infrequente de angina porém grave devido ao risco de morte súbita, angina refratária e disfunção miocárdica. Cerca de 7-29% dos pacientes com hipertensão pulmonar apresentam sintomas anginosos que podem estar relacionados à CE...
BACKGROUND: Exercise tests are an important tool in the investigation of myocardial ischemia. The ramp protocol has gained increasing importance in clinical practice because of the possibility of individualizing its exercise intensity. OBJECTIVE: To assess and compare the sensitivity, specificity, and ac...

OBJECTIVE: Risk stratification of sudden cardiac death in patients with coronary artery disease is of great importance. We evaluated the association between ventricular repolarization and induction of malignant ventricular arrhythmias on electrophysiological study of patients with coronary artery disease...

BACKGROUND: The ISCHEMIA trial (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) postulated that patients with stable coronary artery disease (CAD) and moderate or severe ischemia would benefit from revascularization. We investigated the relationship between s...
