Tunable Regional Targeting of Self‐Assembling Peptide Nanomaterials in Acute Myocardial Infarction

Advanced NanoBiomed Research, EarlyView.
In a rat model of acute myocardial infarction, intravascular delivery of peptide nanofibers with a collagen‐targeting peptide bound to the infarct vasculature while globular peptide nanoparticles penetrated into the infarct area. This study demonstrated that size, shape, and surface chemistry of nanomaterials control the delivery location within the ...

Angiotensin-converting enzyme insertion/deletion polymorphism does not influence the restenosis rate after coronary stent implantation [PDF]

, 2002
Background. Experimental studies have shown an activation of the angiotensin-converting enzyme (ACE) system as a response to endothelial injury. Recent publications have elucidated the hypothesis that the ACE gene polymorphism may influence the level of ...

Impact of Stepwise Balloon Angioplasty for De Novo Femoropopliteal Artery: A Retrospective Observational Study

Health Science Reports
Background and Aims Drug‐coated balloon use in the revascularisation of femoropopliteal (FP) lesions improves patency rates. However, conventional balloon angioplasty sometimes leads to severe artery dissection, which may be prevented using stepwise ...

Drug‐coated balloons: From conventional designs to next‐generation innovations in vascular therapy

BMEMat, EarlyView.
This review traces the evolution of drug‐coated balloons (DCBs) from conventional designs to next‐generation platforms. We highlight innovations in balloon engineering, coating technologies, and therapeutic agents that enhance localized drug delivery while addressing challenges in efficiency, safety, and biocompatibility for vascular and emerging non ...

Left Main Stem Perforation: Management Strategies in a Potentially Catastrophic Event

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Left main stem coronary perforation is a potentially fatal complication of percutaneous coronary intervention if not recognized early and treated emergently. Treating left main stem perforation can be challenging due to the significant hemodynamic effect of one of the important steps, namely balloon tamponade.

Influence of the Residual Gensini Score on Prognosis of Patients With ST‐Elevation Myocardial Infarction

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The residual Gensini score (rGS) was developed to quantify the severity of coronary atheroma burden after coronary revascularisation. The predictive value of the rGS for clinical outcomes in patients with ST‐segment elevation myocardial infarction (STEMI) remains unexplored.
