Evaluating the quality of implantation of percutaneous ventricular restoration device (Parachute®) by cardiac computed tomography
2016
Background The Parachute is a novel percutaneously implanted ventricular partitioning device (VPD) that has emerged as a safe and feasible treatment option for patients with heart failure following anterior wall myocardial infarction. VPD efficacy is likely dependent on optimal device placement, but to date there are no published data examining the effect of device positioning on patient outcomes. Methods and results We retrospectively identified 32 patients successfully implanted with the Parachute device, all of whom underwent cardiac computed tomography (CCT) at baseline and after 6 months of follow-up. Patients were divided into two groups based on self-reported improvement in New York …
Evaluation of the short- and long-term safety and therapy outcomes of the everolimus-eluting bioresorbable vascular scaffold system in patients with …
2015
Abstract Background Third-generation drug-eluting metal stents are the gold standard for treatment of coronary artery disease. The permanent metallic caging of the vessel, however, can result in limited vasomotion, chronic inflammation, and late expansive remodeling, conditions that can lead to late and very late stent thrombosis. The development of bioresorbable scaffolds (BRSs) promises advantages over metal stents due to complete biodegradation within 2–4 years. Theoretically, since vessel scaffolding is temporary and no permanent implant remains in the vessel, BRSs, as opposed to metal stents, once degraded would no longer be potential triggers for stent-related adverse events or side e…
Hybrid Coronary Percutaneous Treatment with Metallic Stents and Everolimus-Eluting Bioresorbable Vascular Scaffolds: 2-years Results from the GABI-R …
2019
The limitations of the first-generation everolimus-eluting coronary bioresorbable vascular scaffolds (BVS) have been demonstrated in several randomized controlled trials. Little data are available regarding the outcomes of patients receiving hybrid stenting with both BVS and drug-eluting stents (DES). Of 3144 patients prospectively enrolled in the GABI-Registry, 435 (age 62 ±
Five-year outcomes following timely primary percutaneous intervention, late primary percutaneous intervention, or a pharmaco-invasive strategy in ST-…
2019
Abstract Aims ST-segment elevation myocardial infarction (STEMI) guidelines recommend primary percutaneous coronary intervention (pPCI) as the default reperfusion strategy when feasible ≤120 min of diagnostic ECG, and a pharmaco-invasive strategy otherwise. There is, however, a lack of direct evidence to support the guidelines, and in real-world situations, pPCI is often performed beyond recommended timelines. To assess 5-year outcomes according to timing of pPCI (timely vs. late) compared with a pharmaco-invasive strategy (fibrinolysis with referral to PCI centre). Methods and results The French registry of Acute ST-elevation and non-ST-elevation Myocardial Infarction (FAST-MI) programme c…
Periodontitis, coronary heart disease and myocardial infarction: treat one, benefit all
2020
: Periodontal disease is conventionally defined as an inflammatory condition affecting the tissues surrounding and supporting the teeth (i.e. gum and periodontium). Recent statistics show that the prevalence of this condition is continuously growing worldwide, thus raising severe healthcare concerns, not only for local problems emerging from poor oral health, but also for the potential risk of developing systemic complications. Therefore, this article aims to provide an update on the intriguing association between periodontitis, coronary heart disease (CHD) and/or myocardial infarction (MI). Taken together, the available published information seems to support the existence of a significant …
Causal linear parametric model for baroreflex gain assessment in patients with recent myocardial infarction
2001
Spectral and cross-spectral analysis of R-R interval and systolic arterial pressure (SAP) spontaneous fluctuations have been proposed for noninvasive evaluation of baroreflex sensitivity (BRS). However, results are not in good agreement with clinical measurements. In this study, a bivariate parametric autoregressive model with exogenous input (ARXAR model), able to divide the R-R variability into SAP-related and -unrelated parts, was used to quantify the gain (αARXAR) of the baroreflex regulatory mechanism. For performance assessing, two traditional noninvasive methods based on frequency domain analysis [spectral, baroreflex gain by autogressive model (αAR); cross-spectral, baroreflex gain…
P674Metabolic deregulation in myocardial infarction is mediated by PGC-1 alpha pathway
2014
Purpose: In the context of myocardial infarction (MI) the availability of metabolites is clearly restricted, therefore a fuel metabolic shifts takes place. Previous studies have indicated that peroxisome proliferator activated receptor co-activator alpha (PGC-1α) pathway is a crucial regulator of cardiac metabolism in response to cardiac stress. Here we address the role of PGC-1α in regulating metabolic changes of MI. Methods: We studied a group of 12 common swine in which anterior MI was induced by means of angioplasty balloon inflation. A series of 6 swine were sacrificed at 48h post-infarction (acute infarction group) and another series of 6 swine were sacrificed at 3 weeks (chronic infa…
Platelet Function Changes in Acute Myocardial Infarction
1984
Whether the thrombotic component of myocardial infarction is primary or secondary in a given patient, platelet function alterations can influence many mechanisms — operating at the microenvi-ronmental level — from which it depends if the thrombotic lesion grows or sends platelet emboli to the smaller myocardial vessels.
Comparison of One-Year Outcomes Between the ihtDEStiny BD Stent and the Durable-Polymer Everolimus- and Zotarolimus-Eluting Stents: A Propensity-Scor…
2021
Abstract 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 . Primary outcome was the target vessel failure (TVF) at 12 month…
0128: CHA2DS2-VASc score estimates in-hospital mortality beyond GRACE score after acute myocardial infarction
2016
International audience; Background and aimsCHA2DS2VASc score have recently been suggested to predict death in patients with Atrial Fibrillation (AF). In acute myocardial infarction (AMI), silent AF is more common than symptomatic AF and associated with poor prognosis. In patients with AMI, we aimed to assess the distribution of CHA2DS2VASc score in patients with silent or symptomatic AF and the association of the score with mortality.Methods849 consecutive AMI were prospectively analyzed by continuous ECG monitoring (CEM) 30 sec. Symptomatic AF was defined as any AF occurring on ECG during the hospital stay, resulting in clinical symptoms or need for urgent cardioversion. The population was…
