Creating a dynamic easy-to-use checklist that condenses key information about lipidomic experiments into common terminology will enhance the field's consistency, comparability, and repeatability. Here, we describe ...
Liraglutide Improves Myocardial Perfusion and Energetics and Exercise Tolerance in Patients With Type 2 Diabetes.
JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY - 06 Aug 2024
Type 2 diabetes (T2D) is characterized by insulin resistance (IR) and dysregulated insulin secretion. Glucagon-like peptide-1 receptor agonist liraglutide promotes insulin secretion, whereas thiazolidinedione-pioglitazone decreases IR. This study aimed to compare the efficacies of increasing insulin secretion vs decreasing IR strategies for improving myocardial perfusion, energetics, and functi...
Age-Related Blood Pressure Gradients Are Associated With Blood Pressure Control and Global Population Outcomes.
HYPERTENSION (DALLAS, TEX. : 1979) - 07 Aug 2024
The strong relationship between blood pressure (BP) and age is well known. Limited evidence suggests that a steeper age-BP slope may be associated with an increased risk of adverse outcomes. The May Measurement Month campaign enables an investigation of geographic, socioeconomic, and sex differences in age-BP gradients and their association with public-health outcomes. Cross-sectional, annual g...
Routine Protamine Administration for Bleeding in Transcatheter Aortic Valve Implantation: The ACE-PROTAVI Randomized Clinical Trial.
JAMA CARDIOLOGY - 14 Aug 2024
Vascular complications after transfemoral transcatheter aortic valve implantation (TAVI) remain an important cause of procedure-related morbidity. Routine reversal of anticoagulation with protamine at the conclusion of transfemoral TAVI could reduce complications, but data remain scarce. To evaluate the efficacy and safety of routine protamine administration after transfemoral TAVI. The ACE-PRO...
Absolute cardiovascular risk assessment using 'real world' clinic blood pressures compared to standardized unobserved and ambulatory methods: an observational study.
HYPERTENSION RESEARCH : OFFICIAL JOURNAL OF THE JAPANESE SOCIETY OF HYPERTENSION - 16 Aug 2024
Clinic blood pressure (BP) is recommended for absolute cardiovascular disease (CVD) risk assessment. However, in 'real-world' settings, clinic BP measurement is unstandardised and less reliable compared to more rigorous methods but the impact for absolute CVD risk assessment is unknown. This study aimed to determine the difference in absolute CVD risk assessment using real-world clinic BP compa...
Discovery of an embryonically derived bipotent population of endothelial-macrophage progenitor cells in postnatal aorta.
NATURE COMMUNICATIONS - 17 Aug 2024
Converging evidence indicates that extra-embryonic yolk sac is the source of both macrophages and endothelial cells in adult mouse tissues. Prevailing views are that these embryonically derived cells are maintained after birth by proliferative self-renewal in their differentiated states. Here we identify clonogenic endothelial-macrophage (EndoMac) progenitor cells in the adventitia of embryonic...
