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…

Epidemiological approach of type 2 myocardial infarction : Etiologies, characteristics, treatment and prognosis.

2020

Introduction: Type 2 Myocardial infarction (MI)has been recently defined as an imbalance between oxygen supply and demand, in the absence of atherothromthrombosis. This work aimed to describe the main etiolgies as well as epidemiological, clinical and prognostic characteristics.Method: Data from patients with type 2 MI were collected from the RICO cohort (Observatoire des Infarctus de Cote d'Or). In a complementary work, we analyzed the retrospective data of the emergency department of Dijon University Hospital.Results: Among 4,436 consecutive patients hospitalized for MI in Dijon emergency department over 3 years, 947 (21%) had type 2 MI (median age: 81 years). In the RICO cohort, 4,572 co…

Timing effect of intramyocardial hydrogel injection for positively impacting left ventricular remodeling after myocardial infarction

2015

Intramyocardial injection of various injectable hydrogel materials has shown benefit in positively impacting the course of left ventricular (LV) remodeling after myocardial infarction (MI). However, since LV remodeling is a complex, time dependent process, the most efficacious time of hydrogel injection is not clear. In this study, we injected a relatively stiff, thermoresponsive and bioabsorbable hydrogel in rat hearts at 3 different time points - immediately after MI (IM), 3 d post-MI (3D), and 2 w post-MI (2W), corresponding to the beginnings of the necrotic, fibrotic and chronic remodeling phases. The employed left anterior descending coronary artery ligation model showed expected infar…

Biochemical biomarkers alterations in Coronavirus Disease 2019 (COVID-19)

2020

Abstract Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a respiratory disease, which can evolve into multi-organ failure (MOF), leading to death. Several biochemical alterations have been described in COVID-19 patients. To date, many biomarkers reflecting the main pathophysiological characteristics of the disease have been identified and associated with the risk of developing severe disease. Lymphopenia represents the hallmark of the disease, and it can be detected since the early stage of infection. Increased levels of several inflammatory biomarkers, including c-reactive protein, have been found in COVID-19 patients and associ…

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

Plasma HDL cholesterol and risk of myocardial infarction: a mendelian randomisation study

2012

BACKGROUND: High plasma HDL cholesterol is associated with reduced risk of myocardial infarction, but whether this association is causal is unclear. Exploiting the fact that genotypes are randomly assigned at meiosis, are independent of non-genetic confounding, and are unmodified by disease processes, mendelian randomisation can be used to test the hypothesis that the association of a plasma biomarker with disease is causal. METHODS: We performed two mendelian randomisation analyses. First, we used as an instrument a single nucleotide polymorphism (SNP) in the endothelial lipase gene (LIPG Asn396Ser) and tested this SNP in 20 studies (20,913 myocardial infarction cases, 95,407 controls).

Left bundle branch block and myocardial infarction, a diagnosis not always easy: Our experience and review of literature

2012

The occurrence of left bundle branch block (LBBB) is quite common in clinical practice. The changes in cardiac repolarization, caused by this disorder of electric conduction, may mask the presence of an acute myocardial infarction (AMI), delaying the diagnostic-therapeutic iter, with an important impact on prognosis. We describe the case of a woman of 59 years with LBBB, came to our observation for a constrictive chest pain associated with dyspnea. The diagnostic workup for suspected acute coronary syndrome (ACS), initially conducted only on the analysis of the electrocardiogram (negative TnI at entry), showed the presence of coronary arteries free of stenosis. However, the diagnostic confi…

Predictors of leptin concentration and association with cardiovascular risk in patients with coronary artery disease: results from the AtheroGene stu…

2016

AbstractContext: Leptin is produced in white adipose tissue, but also in human coronary atherosclerotic lesions.Objective: The aim of this study is to assess the prognostic value of leptin in patients with proven coronary artery disease (CAD) (N = 1907).Methods: AtheroGene is a contemporary CAD cohort study (N = 3229). Median follow-up time was 3.8 (Quartile 1/3 with 2.8/4.9) years.Results: Leptin concentration was associated with a hazard ratio (HR) for the fully adjusted model of HR = 1.32 in women but was not significant in men. The endpoint cardiovascular death and non-fatal myocardial infarction was observed in 167 patients.Conclusion: In women with known CAD, increased leptin concentr…
