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.

Association of cyclophilins and cardiovascular risk factors in coronary artery disease.

Cyclophilins are chaperone proteins that play important roles in signal transduction. Among them, cyclophilins A, B, C, and D were widely associated with inflammation and cardiovascular diseases. Cyclophilins A and C have been proposed as coronary artery disease biomarkers.

Adjusting RFR by Predictors of Disagreement, "The Adjusted RFR": An Alternative Methodology to Improve the Diagnostic Capacity of Coronary Indices.

Background: Cutoff thresholds for the "resting full-cycle ratio" (RFR) oscillate in different series, suggesting that population characteristics may influence them. Likewise, predictors of discordance between the RFR and fractional flow reserve (FFR) have been documented. The RECOPA Study showed that diagnostic capacity is reduced in the RFR "grey zone", requiring the performance of FFR to rule out or confirm ischemia.

The role of invasive coronary physiology in Takotsubo Syndrome.

The pathophysiology of Takotsubo Syndrome has not yet been precisely defined. Different hypotheses have been proposed, including cardiotoxicity due to catecholaminergic hormone release, metabolic disorders, coronary microvascular dysfunction and epicardial coronary artery spasm. Invasive coronary physiology is considered the cornerstone to understand physiological assessment of coronary blood flow in this setting.

[Increase of serum cyclophilin C levels in the follow-up of coronary artery disease: A biomarker and possible clinical predictor].

Objective: This study is aimed at investigating the changes in serum CypC levels and their relationship with cardiovascular events at 12 months of follow-up in coronary artery disease (CAD) patients.

Methods: The study included a total of 125 subjects (40 patients with acute CAD, 40 patients with chronic CAD, and 45 control volunteers) and we analyzed plasma CypC levels from baseline to 6 and 12 months for a better understanding of its behavior in atherosclerosis.

Results: Serum CypC levels were shown to be gradually increased in CAD patients (30.

Usefulness of the Hybrid RFR-FFR Approach: Results of a Prospective and Multicenter Analysis of Diagnostic Agreement between RFR and FFR-The RECOPA (REsting Full-Cycle Ratio Comparation versus Fractional Flow Reserve (A Prospective Validation)) Study.

Background: The resting full-cycle ratio (RFR) is a novel resting index which in contrast to the gold standard (fractional flow reserve (FFR)) does not require maximum hyperemia induction. The objectives of this study were to evaluate the agreement between RFR and FFR with the currently recommended thresholds and to design a hybrid RFR-FFR ischemia detection strategy, allowing a reduction of coronary vasodilator use.

Materials And Methods: Patients subjected to invasive physiological study in 9 Spanish centers were prospectively recruited between April 2019 and March 2020.

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.

12-month clinical outcomes after Magmaris percutaneous coronary intervention in a real-world cohort of patients: Results from the CardioHULA registry.

Introduction And Objectives: Clinical evidence on the bioresorbable magnesium scaffolds (BRS) is still scarce. We aim to assess clinical outcomes after magnesium BRS deployment in a real-world cohort of patients.

Methods: We included in a non-randomized, prospective, single-center registry of all patients treated with at least one Magmaris device in our cath lab.

Magnesium versus poly-L-lactic acid bioresorbable scaffolds: in vivo optical coherence tomography comparison of mechanical performance.

Background: Different mechanical properties have been suggested for metallic bioresorbable vascular scaffolds (BVS) in comparison to polymeric BVS. We aim to evaluate the acute mechanical performance of Magmaris scaffold in comparison to Absorb.

Materials And Methods: Two groups of 10 coronary lesions treated with Magmaris and Absorb 1.

Assessment with intracoronary pressure and flow guidewire, at baseline and after intracoronary adenosine infusion, in a patient with Takotsubo syndrome.

We present the case of a patient with Takotsubo syndrome assessed by intracoronary flow and pressure guidewire, showing elevation of intracoronary pressures at the level of the anterior descending artery, and thus demonstrating a new therapeutic target in a still little understood etiopathogenic entity. The results of this test have never been previously reported in Takotsubo patients.

Magmaris very late in-scaffold restenosis: Has the "black boxes" nightmare come back?

Magnesium Bioresorbable Scaffold (Magmaris, Biotronik) is a device with promising outcomes at 24 months of follow up. Previous studies with first generation, everolimus-eluting Bioresorbable Vascular Scaffold (Absorb, Abbott) showed that very late restenosis seems to be attributed to pure intrascaffold tissue growth but very late. Magmaris very late restenosis has not been previously published, probably because of the 95% of resorption at 12 months.

Carotid plaque is a predictor of major adverse cardiac and cerebrovascular events in patients undergoing coronary angiography.

Background: Carotid disease, measured as carotid intima-media thickness (CIMT) and carotid plaque (CP), is associated with major adverse cardiac and cerebrovascular events (MACCE) in people without the previous atherosclerotic disease; however, there are few published data in patients undergoing coronary angiography. The aim of the study is to determinate if the carotid disease is associated with MACCE after coronary angiography.

Methods: A total of 390 consecutive patients underwent coronary angiography after exercise echocardiography and carotid ultrasonography between 2002 and 2013.

Bioresorbable vascular scaffolds in coronary chronic total occlusions revascularization: safety assessment related to struts coverage and apposition in 6-month OCT follow-up.

Beneficial properties of bioresorbable vascular scaffolds (BVS) regarding to vasomotility restoration and no caging of the vessel make them attractive devices in chronic total occlusions (CTO) revascularization. However, more evidence is needed attending to their use in this specific setting. We aim to determine feasibility and safety of BVS use in CTO revascularization attending to struts coverage and apposition, as well as re-stenosis and stent thrombosis (ST) rates.

Alteration of platelet GPVI signaling in ST-elevation myocardial infarction patients demonstrated by a combination of proteomic, biochemical, and functional approaches.

The platelet-specific collagen receptor glycoprotein VI (GPVI) is critical for the formation of arterial thrombosis in vivo. We analyzed GPVI-activated platelets from ST-elevation myocardial infarction (STEMI) patients and matched stable coronary artery disease (SCAD) controls in order to provide novel clues on the degree of involvement of GPVI signaling in the acute event. Firstly, platelets were isolated from systemic venous blood and activated with the GPVI specific agonist CRP (collagen-related peptide).
