The new clinical standard of integrated quadruple stress echocardiography with ABCD protocol

Cardiovascular Ultrasound, 2018
Background The detection of regional wall motion abnormalities is the cornerstone of stress echocardiography. Today, stress echo shows increasing trends of utilization due to growing concerns for radiation risk, higher cost and stronger environmental ...

Coronary Flow and Reserve by Enhanced Transthoracic Doppler Trumps Coronary Anatomy by Computed Tomography in Assessing Coronary Artery Stenosis

Diagnostics, 2021
We report the case of a 71-year-old patient with many risk factors for coronary atherosclerosis, who underwent computed coronary angiography (CTA), in accordance with the guidelines, for recent onset atypical chest pain. CTA revealed critical (>50% lumen

Investigation on the Influence of Protein Corona and Platelet Adhesion on Storage Bag Surface on the Platelet Storage Lesion

Advanced Healthcare Materials, EarlyView.
Platelet quality deteriorates during storage due to protein and platelet adhesion to current bag materials. Here, polymer coatings are identified that reduce adhesion and translated them to mini‐storage bags. Platelet quality are not impacted, despite significantly reducing adhesion.

CXCR2 Inhibition – a novel approach to treating CoronAry heart DiseAse (CICADA): study protocol for a randomised controlled trial

Trials, 2017
Background There is emerging evidence of the central role of neutrophils in both atherosclerotic plaque formation and rupture. Patients with lower neutrophil counts following acute coronary syndromes tend to have a greater coronary flow reserve, which is

An intact animal model for the assessment of coronary blood flow regulation “Coronary blood flow regulation”

Physiological Reports, 2020
Coronary blood flow adapts to metabolic demand ("metabolic regulation") and remains relatively constant over a range of pressure changes ("autoregulation"). Coronary metabolic regulation and autoregulation are usually studied separately.
