Effect of streptozotocin-induced diabetes on myocardial blood flow reserve assessed by myocardial contrast echocardiography in rats [PDF]
Cardiovascular Diabetology, 2008 The role of structural and functional abnormalities of small vessels in diabetes cardiomyopathy remains unclear. Myocardial contrast echocardiography allows the quantification of myocardial blood flow at rest and during dipyridamole infusion.

European Journal of Hybrid Imaging, 2018 Background Cardiac imaging by means of myocardial Positron Emission Tomography/Computed Tomography (PET/CT) is being used increasingly to assess coronary artery disease, to guide revascularization decisions with more accuracy, and it allows robust ...

Echocardiography, 2008 Background: Sickle cell disease (SCD) is characterized by obstruction of microvessels leading to ischemia and necrosis. We have aimed to demonstrate whether myocardial contrast echocardiography (MCE) is able to detect myocardial perfusion abnormalities in SCD patients and to assess their relationship with left ventricle (LV) perfusion and systolic ...

Fractional Flow Reserve or Coronary Flow Reserve for the Assessment of Myocardial Perfusion [PDF]
Current Cardiology Reports, 2018 Accumulating evidence exists for the value of coronary physiology for clinical decision-making in ischemic heart disease (IHD). The most frequently used pressure-derived index to assess stenosis severity, the fractional flow reserve (FFR), has long been considered the gold standard for this purpose, despite the fact that the FFR assesses solely ...

Prognostic value of myocardial flow reserve vs corrected myocardial flow reserve in patients without obstructive coronary artery disease. [PDF]
J Nucl CardiolMyocardial flow reserve (MFR) by positron emission tomography (PET) is a validated measure of cardiovascular risk. Elevated resting rate pressure product (RPP = heart rate x systolic blood pressure) can cause high resting myocardial blood flow (MBF), resulting in reduced MFR despite normal/near-normal peak stress MBF.

Fractional Flow Reserve in Patients With Prior Myocardial Infarction [PDF]
Circulation, 2001 Background — Fractional flow reserve (FFR), an index of coronary stenosis severity, can be calculated from the ratio of hyperemic distal to proximal coronary pressure.

Abnormal Myocardial Blood Flow Reserve Observed in Cardiac Amyloidosis [PDF]
, 2016 We performed real-time myocardial contrast echocardiography on a patient with cardiac amyloidosis and previous normal coronary angiography presenting with atypical chest pain to assess myocardial blood flow reserve (MBFR).

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019 Background Concerns exist about reliability of pressure‐wire‐guided coronary revascularization of non‐infarct‐related arteries (non‐IRA). We investigated whether physiological assessment of non‐IRA during the subacute phase of myocardial infarction might
