Coronary Flow Reserve Measured by Myocardial Perfusion Imaging in Patients Following Percutaneous Coronary Intervention

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Despite achieving complete revascularization, patients with coronary artery disease (CAD) may experience adverse outcomes, potentially attributable to coronary microvascular dysfunction (CMD). Coronary flow reserve (CFR), which integrates both epicardial and microvascular coronary function, and a reduced CFR following complete ...

Cardiac Magnetic Resonance Imaging in Patients with Acute Ischemic Stroke and Elevated Troponin: A TRoponin ELevation in Acute Ischemic Stroke (TRELAS) Sub-Study

open access: yesCerebrovascular Diseases Extra, 2019
Background: Elevated high-sensitive cardiac troponin (hs-cTn) can be found in more than 50% of the patients with acute ischemic stroke. The observational TRoponin ELevation in Acute ischemic Stroke (TRELAS) study revealed that about 25% of all stroke ...

Retinal and choroidal vascular changes in coronary heart disease: an optical coherence tomography angiography study.

open access: yesBiomedical Optics Express, 2019
To reveal the association between retinal microvasculature changes and coronary heart disease (CHD), we assessed the full retinal thicknesses of eight areas, the vessel density of four layers (consisting of nine areas) and the flow area in two layers ...

Prevalence and Prognostic Impact of Coronary Chronic Total Occlusions in Patients With Cardiogenic Shock

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Mortality in patients with cardiogenic shock (CS) remains high despite advanced treatment strategies in CS patients, underlining the need for the identification of predictors of prognosis in CS patients. Therefore, the present study investigates the prognostic impact of coronary chronic total occlusions (CTO) in patients with CS ...

Comentário a «Será que a diferença na opacificação coronária corrigida medida por TC é preditora do fluxo coronário?»

open access: yesRevista Portuguesa de Cardiologia, 2011
Objectives: A proof-of-concept study was undertaken to determine whether differences in corrected coronary opacification (CCO) within coronary lumen can identify arteries with abnormal resting coronary flow.

Use of Nuclear Magnetic Resonance Imaging Angiography to Follow-Up Arterial Remodeling in an Animal Model [PDF]

open access: yes, 1998
Appropriately sized arteries in small animals may be possible models for studying the remodeling process as occurs after arterial balloon injury in humans. Magnetic resonance imaging (MRI) is able to noninvasively image tissue in vivo.

A Novel Cardiac Computed Tomography‐Based Calcium Scoring System for Predicting the Use of Atherectomy Devices in Severely Calcified Coronary Lesions

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Cardiac computed tomography (CT) is a well‐established process used to diagnose coronary artery disease; however, its specific advantages in predicting the use of atherectomy devices during percutaneous coronary intervention (PCI) for moderate to severe calcified lesions remain to be determined.

Multi-modality imaging of a left atrial myxoma

open access: yesSAGE Open Medical Case Reports, 2017
Objectives: Although echocardiography has traditionally been used to diagnose myxoma, invasive or non-invasive coronary angiography can be useful diagnostic tool before surgery.
