Coronary artery pathology [PDF]

open access: yesHeart, 2007
The field of coronary artery pathology is overwhelmingly dominated by one disease—atherosclerosis. It is therefore not surprising that insight into the onset of symptomatic coronary artery diseases mainly stems from patients with plaques. Coronary atherosclerosis may lead to relatively benign symptoms, such as stable angina, due to bare stenosis or ...

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

open access: yesAdvanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

EndoTac: An Endoscopic Camera‐Based Tactile Sensor with High Sensitivity for Minimally Invasive Surgery

open access: yesAdvanced Science, EarlyView.
EndoTac presents a trocar‐compatible endoscopic vision‐based tactile sensor that uses a convex mirror to enlarge side‐facing tactile coverage during minimally invasive vessel palpation. Distorted tactile images are unwarped and processed by a learning model to estimate vascular deformation, enabling sensitive, spatially distributed tactile perception ...

Copper‐Doped Prussian Blue Nanozymes With Hyaluronic Acid‐Mediated Targeting Alleviate Oxidative Stress and Regulate Cholesterol Handling for Atherosclerosis Therapy

open access: yesAdvanced Science, EarlyView.
CuPB@HA is a CD44‐associated, plaque‐targeted nanozyme that alleviates oxidative stress, inflammation, and lipid accumulation in macrophages. By reducing CD36‐dependent lipid uptake and promoting ABCA1/ABCG1‐mediated cholesterol handling, it improves macrophage function, preferentially accumulates in atherosclerotic lesions, reduces plaque burden, and ...

Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair

open access: yesAdvanced Science, EarlyView.
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.

CHA2DS2-VASc score as a mortality predictor in acute heart failure with preserved ejection fraction

open access: yesFrontiers in Cardiovascular Medicine
BackgroundThe mortality rate in decompensated heart failure (HF) with preserved ejection fraction (HFpEF) remains high. In recent years the prognostic role of CHA2DS2-VASc score, initially formulated for embolic risk prediction in atrial fibrillation ...
