Impact of pre-admission physical activity on benefits of physiology-guided complete revascularization in older patients with myocardial infarction: insights from the FIRE trial.

Aims: The present analysis from the Functional Assessment in Elderly Myocardial Infarction Patients with Multivessel Disease (FIRE) trial aims to explore the significance of pre-admission physical activity and assess whether the benefits of physiology-guided complete revascularization apply consistently to sedentary and active older patients.

Methods And Results: Patients aged 75 years or more with myocardial infarction (MI) and multivessel disease were randomized to receive physiology-guided complete revascularization or culprit-only strategy. The primary outcome was a composite of death, MI, stroke, or any revascularization within a year.

Aim: To investigate key aspects of the problem of myocardial revascularization failure (MRF) and repeat or secondary myocardial revascularization (SR) in contemporary practice.

Methods: The registry of secondary revascularization (REVASEC) is an investigator-initiated, multicenter, prospective registry enhanced with data monitoring and independent event adjudication (ClinicalTrials.govNCT03349385).

Percutaneous Intervention in Diffuse Coronary Disease: Overlapping Versus Single Very Long Stent Technique. Results From the OVERLONG Registry.

Background: Both stent length and stent overlap are associated with worse outcomes in the percutaneous treatment of diffuse coronary artery disease (dCAD). However, evidence comparing these issues is scarce. We aimed to compare the results between the use of single very long stent (VLS) and ≥2 overlapping stents (OS) in the treatment of dCAD.

Clinical implications of arterial hypertension in patients with spontaneous coronary artery dissection.

Background: Spontaneous coronary artery dissection (SCAD) is a rare but increasingly recognized cause of acute coronary syndrome. Many patients with SCAD have associated coronary risk factors. However, the implications of arterial hypertension in SCAD patients remain unknown.

Spontaneous coronary artery dissection in old patients: clinical features, angiographic findings, management and outcome.

Aims: Spontaneous coronary artery dissection (SCAD) is a relatively rare but well-known cause of acute coronary syndrome. Clinical features, angiographic findings, management and outcomes of SCAD in old patients (>65 years of age) remain unknown.

Methods And Results: The Spanish multicentre prospective SCAD registry (NCT03607981), included 318 consecutive patients with SCAD.

Long-Term Follow-Up of Percutaneous Coronary Intervention With Paclitaxel-Eluting Balloon Catheter.

Drug-eluting balloons currently constitute a therapeutic tool used in percutaneous coronary interventions (PCI). Long-term results remain unknown. We evaluated the prognosis of PCI using a second generation paclitaxel-eluting balloon (PEB) in real-world patients.

Comparison of One-Year Outcomes Between the ihtDEStiny BD Stent and the Durable-Polymer Everolimus- and Zotarolimus-Eluting Stents: A Propensity-Score-Matched Analysis.

Objectives: We sought to evaluate clinical outcomes in patients treated with the drug-eluting stent ihtDEStiny BD.

Background: The ihtDEStiny BD stent is a metallic sirolimus eluting stent with a biodegradable polymer with both drug and polymer coating the abluminal surface of the stent and balloon.

Methods: In this study, the clinical outcomes of a multicenter prospective registry of patients treated with this stent (DEStiny group) were analyzed and compared with those of a control group of patients treated with durable polymer everolimus or zotarolimus eluting stents (CONTROL group) paired by propensity score matching.

Clinical Prognosis Associated With the Use of Overlapping Stents With Homogenous Versus Heterogeneous Pharmacological Characteristics for the Treatment of Diffuse Coronary Artery Disease.

Background: The clinical impact of percutaneous coronary intervention (PCI) and implantation of overlapping stents (OS) using platforms with the same versus different pharmacological characteristics is unknown. Our objective was to compare the outcomes of PCI with OS according to their pharmacological characteristics.

Methods: In this observational single-center registry, we included all PCI performed from April 2014 to December 2018 in which overlapping drug-eluting stents were implanted.

An Unusual Entity: Woven Coronary Artery Anomaly.

The recognition of woven coronary artery anomaly is difficult because of its rare nature. Optical coherence tomography imaging is challenging due to the tortuosity of the channels; however, it is crucial not only for the differential diagnosis but also to guide the treatment approach.

Angiography and Optical Coherence Tomography Assessment of the Drug-Coated Balloon ESSENTIAL for the Treatment of In-Stent Restenosis.

Objectives: This study sought to assess the efficacy of the drug-coated balloon (DCB) ESSENTIAL for the treatment of in-stent restenosis (ISR).

Background: DCBs have proven a valid therapeutic option for the management of ISR in several clinical trials, yet no class effect can be claimed. Accordingly, every new DCB model has to be individually evaluated through clinical studies.

Magmaris Resorbable Magnesium Scaffold Implantation Assisted by Optical Coherence Tomography to Treat an Acute Coronary Dissection After a Blunt Chest Trauma.

The treatment of coronary lesions caused by blunt chest trauma is controversial. To our knowledge, this is the first report of a coronary dissection related to blunt chest trauma evaluated with OCT and treated with a magnesium resorbable scaffold.

Cocaine-Associated ST-Elevation Myocardial Infarction: Different Pathophysiological Mechanisms.

There are many underlying mechanisms for cocaine-associated myocardial infarction, and the culprit must be elucidated for appropriate therapeutic management. Optical coherence tomography provides unique insights when angiography alone has limited diagnostic value; it also aids in the decision between conservative management and revascularization strategy and guides coronary interventions.

Coronary Artery Tenting After Bypass Grafting: A Key Issue During Percutaneous Coronary Intervention of a Chronic Total Occlusion.

This image series shows how bypass grafts may tent the vessel to which they are anastomosed, potentially changing the expected course of the native coronary vessel. This fact must be taken into account during CTO-PCI, and this case emphasizes the importance of careful analysis of coronary anatomy with several angiographic projections.

Efficacy and Safety of Loading Doses With P2Y12-Receptor Antagonists in Patients Without Dual Antiplatelet Therapy Undergoing Elective Coronary Intervention.

Background: European Guidelines on Myocardial Revascularization recommend clopidogrel loading dose added to acetylsalicylic acid in elective percutaneous coronary interventions (PCIs). However, there is few evidence supporting this recommendation and other P2Y12 inhibitors have not been tested in these patients.

Purpose: To evaluate the effectiveness and safety of different loading doses of clopidogrel and ticagrelor in patients without double antiplatelet therapy and stable coronary artery disease (SCAD) undergoing elective PCI.

Comparison of Clinical Outcomes Between Very Long Stents and Overlapping Stents for the Treatment of Diffuse Coronary Disease in Real Clinical Practice.

Background: The stent length as well as the stent overlap for the percutaneous treatment of diffuse coronary disease have been considered predictors of adverse events. However, there are no comparative data on the use of very long stents or overlapping stents in this scenario.

Objective: To compare the clinical results of very long stents (≥40 mm) or overlapping stents in real clinical practice.
