Safety and performance of the ultrathin sirolimus-eluting coronary stent in an all-comer patient population: the S-FLEX UK-II registry.

Objective: We evaluated the clinical safety and performance of the ultrathin strut biodegradable polymer-coated Supraflex Cruz (Sahajanand Medical TechnologiesLtd., Surat, India) sirolimus-eluting stent (SES) in an all-comer patient population requiring coronary stent implantation.

Study Design: The study was a prospective, observational, multicentre, single-arm registry.

Invasive Treatment Strategy for Older Patients with Myocardial Infarction.

Background: Whether a conservative strategy of medical therapy alone or a strategy of medical therapy plus invasive treatment is more beneficial in older adults with non-ST-segment elevation myocardial infarction (NSTEMI) remains unclear.

Methods: We conducted a prospective, multicenter, randomized trial involving patients 75 years of age or older with NSTEMI at 48 sites in the United Kingdom. The patients were assigned in a 1:1 ratio to a conservative strategy of the best available medical therapy or an invasive strategy of coronary angiography and revascularization plus the best available medical therapy.

Transcoronary electrophysiological parameters in patients undergoing elective and acute coronary intervention.

Introduction: Percutaneous coronary intervention is performed routinely in the management of myocardial infarction with obstructive coronary disease, but intervention to arteries supplying nonviable myocardium may be harmful. It is important therefore to establish myocardial viability, and there is an unmet need in current clinical practice for real time viability assessment to aid in decision making. Transcoronary pacing to assess myocardial electrophysiological parameters may be a novel viability assessment technique which could be used in this regard.

Fractional Flow Reserve versus Angiography-Guided Management of Coronary Artery Disease: A Meta-Analysis of Contemporary Randomised Controlled Trials.

Background and Aims: Randomised controlled trials (RCTs) comparing outcomes after fractional flow reserve (FFR)-guided versus angiography-guided management for obstructive coronary artery disease (CAD) have produced conflicting results. We investigated the efficacy and safety of an FFR-guided versus angiography-guided management strategy among patients with obstructive CAD. Methods: A systematic electronic search of the major databases was performed from inception to September 2022.
