Una de cada 4 coronariografías realizadas por isquemia miocárdica presenta lesiones menores al 50% Este dato desencadenó un creciente interés en la comunidad médica. La Sociedad Americana de Cardiología publicó recientemente un artículo que describe la posición consensuada de un grupo de experto...

Coronary Artery Dilation in Children with Febrile Exanthematous Illness without Criteria for Kawasaki Disease

Arq. bras. cardiol; 113 (6), 2019
Abstract Background: Coronary dilatation is the most important complication of Kawasaki disease (KD) and, in addition to some clinical characteristics, is common to KD and febrile exanthematous illnesses (FEIs). Objective: To assess whether children with FEI, who do not meet the criteria for KD, have c...

Lidocaine and pinacidil added to blood versus crystalloid cardioplegic solutions: study in isolated hearts

Abstract Objective: The present study aimed the functional recovery evaluation after long term of cardiac arrest induced by Custodiol (crystalloid-based) versus del Nido (blood-based) solutions, both added lidocaine and pinacidil as cardioplegic agents. Experiments were performed in isolated rat heart p...

Applicability of Longitudinal Strain of Left Ventricle in Unstable Angina

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Unstable angina (UA) is a common cause of hospital admission; risk stratification helps determine strategies for treatment. Objective: To determine the applicability of two-dimensional longitudinal strain (SL2D) for the identification of myocardial ischemia in patients with UA. Me...

Electrocardiographic analysis of V1-V4 leads in infarction by proximal right coronary artery occlusion

Rev. mex. cardiol; 28 (4), 2017
Abstract: Introduction: In some cases, ST segment elevation in right precordial leads in conjunction with inferior leads can be originated by an obstruction of the right coronary artery in its proximal portion, generating an inferior myocardial infarction which involves the right ventricle. Case prese...

Tortuosidade Coronariana e seu Papel na Isquemia Miocárdica em Pacientes sem Obstruções Coronarianas

Este trabalho faz uma revisão sobre o tema de tortuosidade coronariana abordando várias situações na prática clínica aonde a tortuosidade coronariana pode desempenhar um papel relevante e procura avaliar se há correlação entre tortuosidade coronariana e a presença de isquemia miocárdica em pac...

Comparative Study between Perfusion Changes and Positive Findings on Coronary Flow Reserve

Arq. bras. cardiol; 108 (1), 2017
Abstract Background: Functional assessment of coronary artery obstruction is used in cardiology practice to correlate anatomic obstructions with flow decrease. Among such assessments, the study of the coronary fractional flow reserve (FFR) has become the most widely used. Objective: To evaluate the cor...

Síndrome coronariana aguda como apresentação atípica do fenômeno de roubo subclávio

Clin. biomed. res; 37 (3), 2017
Roubo coronariano da subclávia (RCS) é um fenômeno raro que ocorre em pacientes submetidos a cirurgia de revascularização miocárdica com enxerto de artéria torácica interna esquerda (ATIE) e que causa estenose da artéria subclávia ipsilateral e proximal à origem da ATIE. Relatamos o caso de um...

Effects of Nitrate Intake on Myocardial Ischemia-Reperfusion Injury in Diabetic Rats

Arq. bras. cardiol; 107 (4), 2016
Abstract Background: Coronary artery disease is 2-3 times more common in diabetic individuals. Dietary nitrate/nitrite has beneficial effects in both diabetes and cardiovascular disease. It also has protective effects against myocardial ischemia-reperfusion (IR) injury in healthy animals. However, the e...

Desfechos Clínicos da Intervenção Percutânea na Doença Triarterial e de Tronco da Coronária Esquerda

Fundamentos: A revascularização do miocárdio na doença triarterial e de tronco da coronária esquerda (TCE) pode ser realizada por intervenção coronariana percutânea (ICP) ou cirurgia de revascularização do miocárdio (CRM). O estudo SYNTAX demonstrou resultados clínicos equivalentes em pacie...
