Aims Patients with left ventricular systolic dysfunction frequently show abnormal coronary
vascular function, even in the absence of overt coronary artery disease. Moreover, the …

Objectives: This study sought to quantify myocardial blood flow (MBF) and myocardial
perfusion reserve (MPR) in dilated cardiomyopathy (DCM) and examine the relationship …

Dilated cardiomyopathy (DCM) is characterized by ventricular chamber enlargement and
systolic dysfunction with normal ventricular wall thickness. More recent studies have shown …

The interpretation of the heart as a mechanical engine dates back to the teachings of
Leonardo da Vinci, who was the first to apply the laws of mechanics to the function of the …

Background: In patients with idiopathic dilated cardiomyopathy (IDCM), the myocardial
blood flow is markedly depressed. The presence of alterations in the number and length of …

In failing hearts, coronary flow is normal, but the coronary flow reserve (CFR) is reduced, so
demand-induced ischemia (DII) may occur in response to greater demand for O2. The …

Background: Echocardiography is a useful method for screening and assessing response to
cardiac resynchronization therapy (CRT). 3D echocardiography has already established its …

Introduction Non-ischaemic dilated cardiomyopathy (DCM) is defined as dilatation and
systolic impairment of the left ventricle in the absence of significant epicardial coronary …

FUNDAMENTO: A ecocardiografia consiste em método muito útil para seleção e avaliação
de resposta à terapia de ressincronização cardíaca (TRC). O eco 3D já tem seu papel …

Arterial load exerts a profound impact on left ventricular structure and function. Assessments
of pulsatile arterial hemodynamics have provided important insights into the …
