Coronary physiology

, 2021
In brief the aims of this thesis were: 1. to validate a novel generic non-hyperemic diastolic index (dPR). 2. to validate a wireless non hyperemic angiography based FFR technology (vessel FFR, vFFR) and 3. to assess the distribution of post stenting physiologic indices (FFR, dPR and vFFR) and their association with clinical outcome.

Quantitative flow ratio-based outcomes in patients undergoing transcatheter aortic valve implantation quaestio study

Frontiers in Cardiovascular Medicine, 2023
BackgroundCoronary artery disease (CAD) is common in patients with aortic valve stenosis (AS) ranging from 60% to 80%. The clinical and prognostic role of coronary artery lesions in patients undergoing Transcatheter Aortic Valve Implantation (TAVI ...

Agreement between Murray law-based quantitative flow ratio (μQFR) and three-dimensional quantitative flow ratio (3D-QFR) in non-selected angiographic stenosis: A multicenter study

Cardiology Journal, 2022
BACKGROUND: The agreement between single-projection Murray-based quantitative flow ratio (mQFR) and conventional three-dimensional quantitative flow ratio (3D-QFR) has not been reported hitherto.

Integrative Physiology of Coronary Microcirculation.

The Japanese Journal of Physiology, 1999
Coronary microvessels play a crucial role for mechanoenergetic interaction between blood flow and myocardial function, which is not uniform transmurally. Thus, highly organized vascular regulations are required for matching local blood flow with myocardial energy requirement.

Novel Insights Into the Interaction Between the Autonomic Nervous System and Inflammation on Coronary Physiology: A Quantitative Flow Ratio Study

Frontiers in Cardiovascular Medicine, 2021
Background: Heart rate variability (HRV) was proposed as a noninvasive biomarker to stratify the risk of cardiovascular disease. However, it remains to be determined if HRV can be used as a surrogate for coronary artery physiology as analyzed by ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Fluorination: A strategy to tune the interactions of molecules and nanoscale systems with biological matter

FEBS Open Bio, EarlyView.
This minireview explores fluorination as a key strategy to optimize therapeutic molecules and nanocarriers. By incorporating different fluorinated motifs—from single atoms to linear and branched chains—drug delivery, cellular uptake, and colloidal stability can be improved and fine‐tuned.
