Development of a Severity Score System for Thalassemia Syndromes
2019
Introduction Thalassemia Syndromes (TS) are a group of inherited haemoglobin disorders characterized by different phenotype severity falling among heterozygote state, no transfusion dependent thalassemia (NTDT) and transfusion dependent Thalassemia (TDT) (Graffeo et al, 2018; Taher & Saliba, 2017). Several factors, independently by genotype and globin chain unbalance, modulate the severity of ineffective erythropoiesis (Rivella et al, 2015). Considering the complexity of this pathophysiology, one tool to evaluate patients on an individual basis is needed. The aim of this study was to develop a severity scoring system with a view to initiate timely interventions that would prevent any fu…
Do the current guidelines for heart failure diagnosis and treatment fit with clinical complexity?
2022
Heart failure (HF) is a clinical syndrome defined by specific symptoms and signs due to structural and/or functional heart abnormalities, which lead to inadequate cardiac output and/or increased intraventricular filling pressure. Importantly, HF becomes progressively a multisystemic disease. However, in August 2021, the European Society of Cardiology published the new Guidelines for the diagnosis and treatment of acute and chronic HF, according to which the left ventricular ejection fraction (LVEF) continues to represent the pivotal parameter for HF patients’ evaluation, risk stratification and therapeutic management despite its limitations are well known. Indeed, HF has a complex pathophys…
Comparison of different segmentation approaches without using gold standard. Application to the estimation of the left ventricle ejection fraction fr…
2011
International audience; A statistical method is proposed to compare several estimates of a relevant clinical parameter when no gold standard is available. The method is illustrated by considering the left ventricle ejection fraction derived from cardiac magnetic resonance images and computed using seven approaches with different degrees of automation. The proposed method did not use any a priori regarding with the reliability of each method and its degree of automation. The results showed that the most accurate estimates of the ejection fraction were obtained using manual segmentations, followed by the semiautomatic methods, while the methods with the least user input yielded the least accu…
The role of macrophage colony-stimulating factor in patients with acute myocardial infarction: a pilot study.
2011
We assessed whether macrophage colony-stimulating factor (M-CSF) levels are associated with left ventricular systolic dysfunction (LVSD) in patients with acute myocardial infarction (AMI). We studied 56 patients with AMI (mean age: 67 ± 12 years) and identified those with clinical (Killip class >II) or echocardiographic signs (ejection fraction ≤45%) of LVSD. We evaluated the established cardiovascular risk factors and measured several cardiovascular biomarkers, including M-CSF. Serum M-CSF concentrations (pg/mL) were significantly increased in patients with both clinical and echocardiographic signs of LVSD (460 ± 265 vs 290 ± 210, P = .0103 and 493 ± 299 vs 287 ± 174, P = .0028, respec…
Circulating monocyte subsets and heart failure prognosis
2018
Altres ajuts: Fundacio' La MARATO' de TV3 (201502 to ABG, 201516), AdvanceCat with the support of ACCIÓ [Catalonia Trade & Investment, Generalitat de Catalunya], Fundació Bancària La Caixa. Monocytes are a heterogeneous population of effector cells with key roles in tissue integrity restoration and maintenance. Here, we explore the association of monocyte subsets and prognosis in patients with ambulatory heart failure (HF). Monocyte subsets were classified as classical (CD14 ++ /CD16 -), intermediate (CD14 ++ /CD16 +), or non-classical (CD14 + /CD16 ++). Percentage distribution and absolute cell count were assessed in each subset, and multivariable Cox regression analyses were performed wit…
Short-term moderate diet restriction in adulthood can reverse oxidative, cardiovascular and metabolic alterations induced by postnatal overfeeding in…
2016
AbstractWe aimed to determine whether moderate diet restriction could restore cardiac, oxidative and metabolic alterations induced by postnatal overfeeding (PNOF). Litters of C57BL/6 male mice were either maintained at 9 (normal litter, NL), or reduced to 3 (small litter, SL) in order to induce PNOF. At 6 months, half of the NL and SL mice were subjected to 20% calorie-restriction (CR: NLCR, SLCR) for one month, while the other half continued to eat ad libitum (AL: NLAL, SLAL). Six-month old SL mice presented overweight, fat accumulation, hyperleptinemia, glucose intolerance, insulin resistance, increased cardiac ROS production and decreased left ventricular ejection fraction (LVEF). After …
Immunity, Inflammation and Heart Failure. Their Role on Cardiac Function and Iron Status
2019
Aims: Heart failure is a clinical syndrome characterized by subclinical systemic inflammation and immune system activation associated with iron deficiency. No data exist on the various activations of immune-mediated mechanisms of inflammation in heart failure patients with reduced/preserved ejection fraction. We aimed to (1) investigate possible differences in inflammatory parameters and oxidative stress, and (2) detect a different iron status between groups. Materials and Methods: We enrolled 50 consecutive Caucasian outpatients with heart failure. All patients underwent echocardiographic measurements, laboratory determinations, evaluation of iron status and Toll-like receptors, and NF-κB …
Incidence, determinants and prognostic relevance of dyspnea at admission in patients with Takotsubo syndrome: results from the international multicen…
2020
AbstractClinical presentation of Takotsubo syndrome (TTS) may range from acute chest pain to dyspnea: the prognostic role of clinical onset is still controversial. Aim of this study was therefore to investigate the prognostic relevance of dyspnea at presentation in patients with TTS. We analyzed 1,071 TTS patients (median age 72 years, 90% female) enrolled in the international multicenter GEIST registry. Patients were divided according to the presence or absence of dyspnea at hospital admission, as clinically assessed by the accepting physician. The primary endpoint was occurrence of in-hospital complications defined as a composite of pulmonary edema, cardiogenic shock and death. Overall, 3…
Invasive Strategy in Patients With Advanced Diabetes and Non-ST-Segment Elevation Acute Coronary Syndrome. Angiographic Findings and Clinical Follow-…
2006
Introduction and objectives Advanced diabetes can be associated with diffuse coronary artery disease that is difficult to treat by revascularization. We studied angiographic findings and disease progression in patients with advanced diabetes (either insulin-dependent or taking antidiabetic drugs for >5 years) and non-ST-elevation acute coronary syndrome who were being treated using an invasive strategy. Methods The study included 141 patients. The extent of the coronary artery disease was quantified using a score derived from a 29-segment coronary angiogram. The composite endpoint was death, myocardial infarction, or readmission for unstable angina within one year of follow-up. Results The …
Management of Oral Anti-Coagulation in Patients with Heart Failure-Insights from the ThrombEVAL Study
2018
AbstractPatients with heart failure (HF) are frequently anti-coagulated with vitamin K-antagonists (VKAs). The use of long-acting VKA may be preferable for HF patients due to higher stability of plasma concentrations. However, evidence on phenprocoumon-based oral anti-coagulation (OAC) therapy in HF is scarce. The aim of this study was to assess the impact of the presence of HF on quality of phenprocoumon-based OAC and the subsequent clinical outcome. Quality of OAC therapy and the incidence of adverse events were analysed in a cohort of regular care (n = 2,011) from the multi-centre thrombEVAL study program (NCT01809015) stratified by the presence of HF. To assess the modifiability of outc…
