Prognostic Value of Postpercutaneous Coronary Intervention Murray-Law-Based Quantitative Flow Ratio: Post Hoc Analysis From FLAVOUR Trial.

JACC Asia

January 2025

Department of Cardiology, Ren Ji Hospital, School of Medicine, and School of Biomedical Engineering, Shanghai Jiao Tong University, Shanghai, China.

Background: Coronary physiology measured by fractional flow reserve (FFR) is superior to angiography for assessing the efficacy of percutaneous coronary intervention (PCI). Yet, the clinical adoption of post-PCI FFR is limited. Murray law-based quantitative flow ratio (μQFR) may represent a promising alternative, as it can quickly compute FFR from a single angiographic view.

Background: Intravascular imaging (IVI) complements coronary angiography and may help prevent coronary artery perforation (CAP) during percutaneous coronary intervention (PCI).

Objectives: The authors evaluated whether IVI-guided PCI is associated with a lower risk of PCI-related CAP in a real-world cohort.

Methods: This observational study analyzed consecutive PCI procedures from January 2006 to October 2023.

Distinct Circle of Willis anatomical configurations in healthy preterm born adults: a 3D time-of-flight magnetic resonance angiography study.

BMC Med Imaging

January 2025

Oxford Cardiovascular Clinical Research Facility, Division of Cardiovascular Medicine, Radcliffe Department of Medicine, Level 1, Oxford Heart Centre, John Radcliffe Hospital, University of Oxford, Oxford, OX3 9DU, UK.

Background: Preterm birth (< 37 weeks' gestation) alters cerebrovascular development due to the premature transition from a foetal to postnatal circulatory system, with potential implications for future cerebrovascular health. This study aims to explore potential differences in the Circle of Willis (CoW), a key arterial ring that perfuses the brain, of healthy adults born preterm.

Methods: A total of 255 participants (108 preterm, 147 full-term) were included in the analysis.

Objective: In humans, haptoglobin (Hp) exists in two allelic forms, Hp1 and Hp2, that differ significantly in their ability to protect the organism from oxidative stress. It has been proposed that in patients with diabetes mellitus carriers of the Hp2-2 genotype may benefit from vitamin E supplementation. Aim of our study was to investigate if there is evidence regarding a potential interaction between the Hp polymorphism and vitamin E with regard to mortality in individuals at medium-to-high cardiovascular risk with and without diabetes mellitus.

Salivary steroids in acute central serous chorioretinopathy.

Int Ophthalmol

January 2025

University of Pittsburgh, UPMC Eye Center, 203 Lothrop Street, Pittsburgh, PA, 15213, USA.

Purpose: To analyze levels of salivary steroids, including 17-OH-progesterone (17-OHP), androstenedione, dehydroepiandrosterone, cortisol, cortisone, progesterone, testosterone, and estradiol, in patients with acute central serous chorioretinopathy (CSCR) patients.

Methods: Acute CSCR patients and healthy individuals were included in this observational case-control study. Levels of salivary steroids were determined by high-performance liquid chromatography with tandem mass spectrometry detection.
