Systemic levels of trimethylamine N-oxide (TMAO), a pro-atherogenic and pro-thrombotic metabolite produced from gut microbiota metabolism dietary (TMA)-containing nutrients such as choline or carnitine, predict incident cardiovascular event risks in stable primary secondary prevention subjects. However, the prognostic value TMAO setting acute coronary syndromes (ACS) remains unknown.We investigated relationship with among sequential patients presenting ACS two independent cohorts. In...
Using an untargeted metabolomics approach in initial (N = 99 subjects) and replication cohorts 1,162), we discovered structurally identified a plasma metabolite associated with cardiovascular disease (CVD) risks, N6,N6,N6-trimethyl-L-lysine (trimethyllysine, TML). Stable-isotope-dilution tandem mass spectrometry analyses of independent validation cohort 2,140) confirmed TML levels are independently incident (3-year) major adverse event risks (hazards ratio [HR], 2.4; 95% CI, 1.7-3.4)...
Background ECG criteria differentiating Takotsubo cardiomyopathy (TTC) from mainly anterior myocardial infarction (MI) have been suggested; however, this was in small patient populations. Methods and Results Twelve‐lead admission ECGs of consecutive 200 TTC MI patients were compared dichotomized groups based on the presence or absence ST‐elevation (STEMI versus STE‐TTC non‐ST elevation non ST‐elevation‐TTC). When comparing STEMI STE‐TTC, –aVR characteristic with a sensitivity/specificity 43%...
Abstract Aims We aimed to evaluate the frequency, clinical features, and prognostic implications of cardiac arrest (CA) in takotsubo syndrome (TTS). Methods results reviewed records patients with CA known heart rhythm from International Takotsubo Registry. The main outcomes were 60-day 5-year mortality. In addition, predictors mortality during acute TTS phase assessed. Of 2098 patients, 103 included. Compared without CA, more likely be younger, male, have apical TTS, atrial fibrillation...
Abstract Aims Trimethyllysine (TML) serves as a nutrient precursor of the gut microbiota-derived metabolite trimethylamine N-oxide (TMAO) and is associated with incident cardiovascular (CV) events in stable subjects. We examined relationship between plasma TML levels CV patients presenting acute coronary syndromes (ACS). Methods results Plasma were quantified two independent cohorts using mass spectrometry, its was investigated. In Cleveland Cohort (N = 530), comprised to emergency...
The lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) and its shedding product [soluble LOX-1 (sLOX-1)] are implicated in atherosclerotic cardiovascular disease (ASCVD) pathogenesis. Herein, we examined the relationship of sLOX-1 with both fatal events plaque progression patients acute coronary syndromes (ACS).Plasma was assessed at baseline ACS chronic syndrome (CCS) prospectively recruited multicentre SPUM-ACS study, sex- age-matched healthy subjects serving as additional...
Background: Left atrial appendage occlusion (LAAO) is mostly performed by transesophageal echocardiography (TEE) guidance. Intracardiac (ICE) may be an alternative imaging modality for LAAO that precludes the need general anesthesia or sedation. Methods and Results: All consecutive single center, operator candidates were analyzed. Baseline clinical procedural characteristics in‐hospital outcomes compared between patients in whom a Watchman was implanted with ICE vs. TEE In 76 device deployed...
Abstract Background Patients with ST-segment elevation typically feature total coronary occlusion (TCO) of the infarct-related artery (IRA) on angiography, which may result in worse outcomes. Yet, relying solely electrocardiogram (ECG) findings be misleading and those presenting non-ST-segment acute syndromes (NSTE-ACSs) have TCO as well. Herein, we aimed to delineate clinical characteristics outcomes patients ACS stratified by IRA location. Methods A 4787 were prospectively recruited...
Abstract Aims Outcomes after acute coronary syndromes (ACS) are determined by baseline risk profiles, including initial systolic blood pressure (sBP) levels. Herein, we aimed to characterize ACS patients stratified sBP levels and study their relation inflammation, myocardial injury post-ACS outcomes. Methods results We analysed 4724 prospectively recruited according invasively assessed (<100, 100–139, ≥140 mmHg) at admission. Biomarkers of systemic inflammation [high-sensitivity...
Residual shunt following percutaneous patent foramen ovale (PFO) closure has been described in up to 49% of patients and is associated with recurrent cerebrovascular events. Our aim was evaluate the safety, feasibility, midterm outcomes transcatheter residual closure.From 1994 July 2016, 2,679 underwent PFO for treatment presumed paradoxical embolism at our institution. Among them, 100 (3.7%) were referred closure. They constituted study population which a retrospective analysis...
Abstract Background Inflammatory processes can trigger acute coronary syndromes (ACS) which may increase core body temperature (BT), a widely available low‐cost marker of systemic inflammation. Herein, we aimed to delineate baseline characteristics ST‐segment elevation myocardial infarction (STEMI) and non‐ST‐segment ACS (NSTE‐ACS) patients stratified by initial BT assess its predictive utility towards major adverse cardiovascular events (MACE) after the index ACS. Methods From 2012 until...
Background Conventional surgical risk scores lack accuracy in stratification of patients undergoing transcatheter aortic valve replacement (TAVR). Elevated levels midregional proadrenomedullin (MR-proADM) are associated with adverse outcome not only manifest chronic disease states, but also the general population. Objectives We investigated predictive value MR-proADM for mortality an unselected contemporary TAVR Methods prospectively included 153 suffering from severe stenosis who underwent...
The aim of the study was to evaluate occurrence, duration and impact time delays primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI).A total 357 consecutive STEMI patients enrolled prospective Special Program University Medicine ACS (SPUM-ACS) cohort were included. In order identify causes behind a possible treatment delay, we constructed four different points which included: 1) symptom onset hospital arrival, 2) arrival catheterization...
