Impact of monitoring on detection of arrhythmia recurrences in the ESC-EHRA EORP atrial fibrillation ablation long-term registry

2019

Abstract Aims Monitoring of patients after ablation had wide variations in the ESC-EHRA atrial fibrillation ablation long-term (AFA-LT) registry. We aimed to compare four different monitoring strategies after catheter AF ablation. Methods and results The ESC-EHRA AFA-LT registry included 3593 patients who underwent ablation. Arrhythmia monitoring during follow-up was performed by 12-lead electrocardiogram (ECG), Holter ECG, trans-telephonic ECG monitoring (TTMON), or an implanted cardiac monitoring (ICM) system. Patients were selected to a given monitoring group according to the most extensive ECG tool used in each of them. Comparison of the probability of freedom from recurrences was perfo…

Control of irregular cardiac rhythm

2018

International audience; The aim of this work is to investigate the chaos control of the one di- mensional map which modelizes the duration of the current cardiac action potential (APD) as a function of the previous one. Using OGY control method, we obtain very satisfactory numerical results to stabilize the irregular heart rhythm into the normal rhythm.

Cardiac Computed Tomography Angiography Follow-Up of Resorbable Magnesium Scaffolds.

2021

Abstract Introduction An ancillary advantage of bioresorbable scaffolds is the possibility of non-invasive imaging assessment of the treated coronary segment. Cardiac computed tomography angiography (CCTA) studies of resorbable magnesium scaffolds (RMS) are scarce. Methods In this collaborative, international study, nine patients who had an RMS implanted underwent CCTA as part of follow-up assessment. Core-lab blinded quantitative and qualitative assessment was performed by an independent CCTA investigator. Results Eight studies were amenable for quantitative analysis, and the blinded CT investigator successfully located and evaluated patency of RMS in all cases. The CCTA follow-up in-scaff…

Sex differences in the management of patients with acute coronary syndrome: A population-based ecological cross-sectional study in Spain

2021

Abstract Introduction and objectives Despite evidence of a reduction in the incidence and mortality of acute coronary syndrome (ACS), some studies have highlighted differences in outcomes between men and women. We aimed to explore sex differences in the management and treatment of patients with ACS in Spain. Methods This ecological cross-sectional study combined ACS data from 10 Spanish registries (54 centres). Meta-regression analysis was performed using aggregated data of baseline characteristics, interventional procedures, treatments, and events that occurred during hospitalization and one-year follow-up. Results Aggregated data from 34 605 patients (75.1% men) was included. ST-segment e…

IMPROVE-IT: what have we learned?

2016

Purpose of review: Recent studies and dyslipidemia treatment guidelines indicate that combination lipid-lowering therapy is frequently needed and its use has increased in recent years. Ezetimibe and simvastatin as a fixed dose is an efficacious treatment choice based on positive results of the recent IMProved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVE-IT). In this review, we discuss recent controversies surrounding ezetimibe and provide clinical perspective on the results of the IMPROVE-IT study. Recent findings: IMPROVE-IT is the first trial that demonstrates a significant clinical benefit of a nonstatin hypolipidemic agent (ezetimibe) used in combination with sta…

A new approach to ticagrelor-based de-escalation of antiplatelet therapy after acute coronary syndrome. A rationale for a randomized, double-blind, p…

2021

The risk of ischemic events gradually decreases after acute coronary syndrome (ACS), reaching a stable level after 1 month, while the risk of bleeding remains steady during the whole period of dual antiplatelet treatment (DAPT). Several de-escalation strategies of antiplatelet treatment aiming to enhance safety of DAPT without depriving it of its efficacy have been evaluated so far. We hypothesized that reduction of the ticagrelor maintenance dose 1 month after ACS and its continuation until 12 months after ACS may improve adherence to antiplatelet treatment due to better tolerability compared with the standard dose of ticagrelor. Moreover, improved safety of treatment and preserved anti-is…

Indicadores pronósticos del síndrome coronario agudo sin elevación del segmento ST

2003

Objectives. We analyzed whether the study of systolic function by echocardiography adds independent information to that afforded by biochemical markers in predicting six-month major events after non-ST elevation acute coronary syndrome. Patients and method. Baseline clinical and electrocardiographic data as well as serum concentrations of troponin, myoglobin, C-reactive protein, fibrinogen and homocysteine were recorded prospectively in 515 consecutive patients admitted because of non-ST elevation acute coronary syndrome. Ejection fraction (echocardiogram) was determined in 248 cases (48%). Predictors of cardiac death or infarction within the following six months were analyzed. Results. In …

Baseline CHA 2 DS 2 ‐VASc score and prognosis in octogenarians with non‐ST segment elevation acute coronary syndrome

2021

Background CHA2DS2-VASc Score is widely used to predict thromboembolic risk in patients with Atrial Fibrillation (AF). We sought to study if this score predicts outcomes in elderly patients with Non-ST segment Elevation Acute Coronary Syndromes (NSTEACS). Methods The multicenter LONGEVO-SCA prospective registry included 532 unselected patients with NSTEACS aged ≥80 years. Data to calculate CHA2DS2-VASc Score were available in 523 patients (98.3%). They were classified according to CHA2DS2-VASc Score: group 1 (score ≤ 4), and 2 (5-9). We studied outcomes in terms of mortality or readmission at 6 months follow-up. Results A total of 266 patients (51%) had a high CHA2DS2-VASc Score (group 2). …

P1319 Speckle tracking echocardiography in patients with acute coronary syndrome: the added value

2020

Abstract Background Speckle tracking echocardiography with assessment of left ventricular global longitudinal strain (GLS) allows to identify early signs of cardiac dysfunction. The superiority of GLS in the prediction of all-cause mortality in the general population compared with LVEF is well known; in addiction GLS improves risk stratification and recognize early left ventricular dysfunction in several clinical setting. Purpose the aim of this study was to assess the diagnostic and prognostic role of global and segmental strain in the early identification of cardiac dysfunction in patients with myocardial infarction without persistent ST segment elevation (NSTEMI) and without obvious wall…
