Involvement of Autonomic Nervous System in New-Onset Atrial Fibrillation during Acute Myocardial Infarction
2020
Background: Atrial fibrillation (AF) is common after acute myocardial infarction (AMI) and associated with in-hospital and long-term mortality. However, the pathophysiology of AF in AMI is poorly understood. Heart rate variability (HRV), measured by Holter-ECG, reflects cardiovascular response to the autonomic nervous system and altered (reduced or enhanced) HRV may have a major role in the onset of AF in AMI patients. Objective: We investigated the relationship between autonomic dysregulation and new-onset AF during AMI. Methods: As part of the RICO survey, all consecutive patients hospitalized for AMI at Dijon (France) university hospital between June 2001 and November 2014 were analyzed …
Low Systolic Blood Pressure and Mortality in Elderly Patients After Acute Myocardial Infarction
2020
Background Optimal blood pressure in elderly patients after acute myocardial infarction is still a matter of debate. In a prospective observational study, we aimed to identify optimal systolic blood pressure during the 48 first hours after admission for acute myocardial infarction and its prognostic value for cardiovascular mortality. Methods and Results From the Observatoire des Infarctus de Côte d'Or survey, all consecutive patients aged >75 years admitted for an acute myocardial infarction in a coronary care unit from 2012 to 2015 and discharged alive were included (n=814). Exclusion criteria were in‐hospital death, cardiogenic shock, and end‐stage renal disease. Average systolic blo…
Prevalence, risk factor burden, and severity of coronary artery disease in patients with heterozygous familial hypercholesterolemia hospitalized for …
2019
Individuals with heterozygous familial hypercholesterolemia (FH) are at high risk of early myocardial infarction (MI). However, coronary artery disease (CAD) burden of FH remains not well described, especially for French patients.The objective of this study was to assess the prevalence of FH and severity of CAD from a large database of a French regional registry of acute MI.All consecutive patients hospitalized for an acute MI in a multicenter database from 2001 to 2017 were considered. FH was diagnosed using an algorithm adapted from the Dutch Lipid Clinic Network criteria. The prevalence and clinical features of FH and the severity of CAD were assessed.Among the 11,624 patients included i…
P4550Growth differentiation factor 15 as an integrative biomarker of heart failure in patients with acute myocardial infarction
2019
Abstract Background Growth differentiation factor 15 (GDF15), a stress-responsive cytokine member of the transforming growth factor-β family, is an emerging biomarker in cardiovascular (CV) diseases. GDF15 is weakly expressed in normal condition but increased in pathological situations such as inflammation, oxidative stress, and left ventricular remodeling. Recent data suggest GDF15 as a marker in heart failure (HF). Purpose We aimed to identify the determinants of GDF15 circulating levels in patients admitted for an acute myocardial infarction (AMI). Methods In our prospective study, all consecutive patients admitted from June 2016 to February 2018 for type 1 AMI in the Coronary Care unit …
P6389Infection and type 2 myocardial infarction: a large observational study from emergency department
2019
Abstract Background Troponin elevation is frequent in patients with acute infection (AI) admitted to emergency unit (EU). Acute infection (AI) has been suggested as a common trigger in type 2 myocardial infarction (T2MI), corresponding to a myocardial oxygen supply-demand mismatch without atherothrombosis. We aim to characterize risk factors of T2MI occurrence and in-hospital mortality among patients admitted to an EU with AI and elevated troponin. Methods Among the medical records of all the patients admitted from January 2014 to December 2016 in a university hospital EU (n=82 543), patients with a diagnosis of AI and elevated troponin Ic (≥0.10μg/L) (n=714) were systematically adjudicated…
Impact of Platelet Reactivity in ACS Patients on Clinical Outcomes with Triple Antithrombotic Therapy
2021
Optimal antithrombotic therapy after percutaneous coronary intervention (PCI) in patients on oral anticoagulants (OAC) remains a clinical conundrum. In fact, combining an OAC with dual antiplatelet therapy (triple antithrombotic therapy, TAT) increases the risk of bleeding. Clopidogrel is the only thienopyridine recommended in TAT patients. Whether its response plays a relevant role in this setting remains uncertain. We aimed to evaluate the level of platelet reactivity inhibition (PRI) achieved by oral TAT in Acute Coronary Syndrome (ACS) patients undergoing PCI and its relationship with outcomes. We performed a multicenter prospective observational study and assessed PRI by vasodilator-st…
P4573In patients with acute myocardial infarction, PCSK9 levels do not predict severity and recurrence of cardiovascular events
2019
Abstract Background In patients with coronary artery disease (CAD), it remains unclear whether serum PCSK9 levels can predict the severity of the disease and the risk of future cardiovascular events. Methods Among the patients admitted for an acute myocardial infarction (MI) from September 2015 to December 2016 in an intensive care unit from a university hospital, serum PCSK9 levels were measured on admission in patients not previously receiving statin therapy. We aimed to evaluate the association between PCSK9 levels, metabolic parameters, severity of CAD on coronary angiography, and the risk of in-hospital events and at one-year follow-up. Results In a total of 648 patients (mean age: 66 …

Sport-related acute myocardial infarction; Context of onset and one-year follow-up
2021
Background Sport-related (SR) acute coronary events are the main cause of sudden cardiac in the setting of sport activities; data are very scarce regarding the context of onset and the follow-up of SR acute myocardial infarction (AMI). Methods We prospectively invited subjects admitted in our University Hospital from April 2018 for a SR-AMI to participate in the IMACS observatory program which addresses to SR-AMI including a 12 months follow-up. Results From April 2018 to April 2019, 21 subjects were included. The mean age of this male population was 57.5 ± 11.0 (median 56). The context of event was available for 21 (provided by family for a subject with out of hospital (OH) SCA). Sport was…
Severe iatrogenic admissions in a coronary care unit:
2013
Introduction: Iatrogenic complications are defined as adverse drug reactions or complications induced by non drug interventions, such as cardiac devices or stimulation techniques. Iatrogenic complications occurring during hospital stay are known to be associated with increased hospital length of stay and mortality. Only few data are available on iatrogenic as cause of hospital admission, particularly in coronary care unit. In patient admitted in coronary care unit for iatrogenic, we aimed a) to analyse their prevalence, type and characteristics, b) to analyse their in-hospital length of stay and mortality and c) to evaluate the predictive factors of severity and mortality. Methods: From 1st…
P4570Prognostic interest of HbA1c and plasma glucose assessment on one-year mortality in non-diabetic patients after acute myocardial infarction
2019
Abstract Background The usefulness of the combined assessment of HbA1c and plasma glucose (PG) in acute myocardial infarction (AMI) in nondiabetic patients remains unclear. Purpose In a large observational study, we aimed to identify the prognostic values of these biomarkers regarding one-year all-cause mortality in nondiabetic patients after AMI. Methods From the “obseRvatoire des Infarctus de Côte d'Or” (RICO) survey database, we included all consecutive nondiabetic patients with AMI (n=6617) from May 2001 to December 2016. Exclusion criteria were: admission known or unknown diabetes, in-hospital death. The primary endpoint was all-cause one-year mortality. The secondary endpoints were: M…

P852Frequency and prognosis of type 2 myocardial infarction vs non ischemic myocardial injury: large observational study from an emergency department
2019
Abstract Background Type 2 Myocardial Infarction (T2MI), due to myocardial oxygen supply-demand mismatch in the absence of atherothrombosis and non-ischemic myocardial injury (NIMI), corresponding to troponin elevation without overt ischemia, are emerging concepts which are suspected to be common in patients hospitalized. However, their respective frequencies, risk profiles and short term prognosis in current routine clinical practice of emergency unit remains to be investigated. Methods Among the medical records of all the patients admitted from January 2014 to December 2016 in a university hospital emergency unit (n=82 543), patients with elevated troponin Ic (≥0.10μg/L) (n=4568) were sys…
