Exercise is the most important physiological stimulus for increased myocardial oxygen
demand. The requirement of exercising muscle for increased blood flow necessitates an …

The prognosis for patients with chronic ischemic left ventricular dysfunction is poor, despite
advances in different therapies. Noninvasive assessment of myocardial viability may guide …

Background—Noncontrast magnetic resonance T1 mapping reflects a composite of both

Aims Patients with type 2 diabetes mellitus (T2DM) are known to have impaired resting
myocardial energetics and impaired myocardial perfusion reserve, even in the absence of …

Background—Microvascular dysfunction in hypertrophic cardiomyopathy (HCM) may create
an ischemic substrate conducive to sudden death, but it remains unknown whether the …

Esta diretriz foi elaborada visando orientar todos os médicos, especialmente os
cardiologistas, para o reconhecimento o mais precoce possível de adultos com risco …

Aims Angiotensin-converting enzyme (ACE) inhibitors improve left ventricular (LV)
remodelling and outcome in heart failure and hypertensive heart disease. They may be …

Objectives: The purpose of this paper was to compare quantitative cardiac magnetic
resonance (CMR) first-pass contrast-enhanced perfusion imaging to qualitative …

Idiopathic dilated cardiomyopathy (IDC) is characterized by left ventricular (LV) enlargement
with systolic dysfunction, other causes excluded. When inherited, it represents familial …
