Comparative Analysis of the Feasibility of Myocardial Blood Flow Index Versus CT-FFR in the Diagnosis of Suspected Coronary Artery Disease

Reviews in Cardiovascular Medicine
Background: Using fluid dynamic modeling, noninvasive fractional flow reserve (FFR) derived from coronary computed tomography angiography (CCTA) data provides better anatomic and functional information than CCTA, with a high diagnostic and discriminatory

Quantification of myocardial blood flow by adenosine-stress CT perfusion imaging in pigs during various degrees of stenosis correlates well with coronary artery blood flow and fractional flow reserve

, 2013
Only few preliminary experimental studies demonstrated the feasibility of adenosine stress CT myocardial perfusion imaging to calculate the absolute myocardial blood flow (MBF), thereby providing information whether a coronary stenosis is flow limiting ...

Myocardial inflammation is associated with impaired mitochondrial oxidative capacity in ischaemic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.
Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.

Effects of sodium–glucose co‐transporter inhibitors on individual clinical endpoints and quality of life

ESC Heart Failure, Volume 12, Issue 2, Page 1271-1282, April 2025.
Effects of SGLTi on Individual Clinical Endpoints and Quality‐of‐Life: outcome from randomized data. Abstract Aims Sodium–glucose co‐transporter inhibitors (SGLTis) have cardiovascular protective effects. We aimed to assess the effects of SGLTis on individual hard clinical endpoints and quality of life (QoL) in patients with cardiovascular risk factors.

A phenomap of TTR amyloidosis to aid diagnostic screening

ESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.
Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.

Comparison of Fractional Flow Reserve and Myocardial Perfusion Imaging in Saphenous Vein Grafts

Catheterization and Cardiovascular Interventions
ABSTRACTBackgroundRevascularization decision‐making for saphenous vein grafts (SVGs) relies on angiographic lesion severity estimation, as studies on fractional flow reserve (FFR) for detecting ischemia in SVGs are scarce.AimsTo compare FFR and quantitative coronary angiography (QCA) of SVGs against myocardial perfusion imaging (MPI) and to establish ...

Left atrial function in uraemic patients: Four‐dimensional automatic left atrial quantitative technology study

ESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.
Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled

Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

ESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

Fractional flow reserve calculation optimized by myocardial computed tomography perfusion information

Quantitative Imaging in Medicine and Surgery
Current computed tomography angiography-derived fractional flow reserve (CT-FFR) diagnosis leaves room for improvement in diagnosing coronary heart disease. In this study, the computed fluid dynamics boundary condition optimization method was used to calculate CT-FFR aiming to improve the diagnostic accuracy of CT-FFR for coronary heart disease.The two
