Echocardiographic Prediction of Successful Weaning From Venoarterial Extracorporeal Membrane Oxygenation.

Background: Weaning from venoarterial extracorporeal membrane oxygenation (VA-ECMO) support fails in 30% to 70% of patients.

Objective: To explore the utility of echocardiographic parameters in predicting successful disconnection from VA-ECMO.

Methods: Patients receiving VA-ECMO in a referral hospital were included.

Short-term mechanical circulatory support in elderly patients.

Background: Age over 70 years seems to confer poor prognosis for patients under mechanical circulatory support (MCS). Advanced age is usually a relative contraindication. Our objective was to assess the impact of age on survival of patients with short-term MCS.

Prehospital troponin as a predictor of early clinical deterioration.

Background And Objectives: Elevated troponin T (cTnT) values are associated with comorbidities and early mortality, in both cardiovascular and noncardiovascular diseases. The objective of this study is to evaluate the prognostic accuracy of the sole utilization of prehospital point-of-care cardiac troponin T to identify the risk of early in-hospital deterioration, including mortality within 28 days.

Methods: We conducted a prospective, multicentric, controlled, ambulance-based, observational study in adults with acute diseases transferred with high priority by ambulance to emergency departments, between 1 January and 30 September 2020.

Levosimendan in veno-arterial extracorporeal membrane oxygenator supported patients: Impact on the success of weaning and survival.

Weaning failure and mortality rates in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) supported patients are significant. Small studies suggest the possible usefulness of levosimendan in this environment, especially in postcardiotomy shock. We performed a retrospective analysis of VA-ECMO implants in a referral hospital comparing weaning failure and survival of patients treated with levosimendan with a control group.

Quercetin, a Promising Clinical Candidate for The Prevention of Contrast-Induced Nephropathy.

Iodinated contrast media (CM) are the leading cause of acute renal failure of toxic origin. Between 21% and 50% of patients that receive them develop contrast-induced nephropathy (CIN). All prophylactic measures used so far have failed to provide effective prevention.

No Differences in Levels of Circulating Progenitor Endothelial Cells or Circulating Endothelial Cells Among Patients Treated With Ticagrelor Compared With Clopidogrel During Non- ST -Segment-Elevation Myocardial Infarction.

Background Ticagrelor use during acute coronary syndromes demonstrated a decrease in all-cause mortality in the PLATO (Platelet Inhibition and Patient Outcomes) trial. This effect has been attributed to a non-platelet-derived improvement in endothelial function. The aim of this study was to determine differences in the number of endothelial progenitor cells and/or circulating endothelial cells found in peripheral blood in patients treated with either ticagrelor or clopidogrel during non-ST-segment-elevation myocardial infarction.

Hemorrhagic pericardial effusion as the debut of acquired hemophilia in a chronic lymphocytic leukemia patient: A case report, and a review of acquired hemophilia A-related hematological malignancies.

Background: Acquired hemophilia A (AHA) is a rare bleeding disease caused by autoantibodies against factor VIII. Spontaneous bleeding symptoms usually affect the skin and muscle, while pericardial effusion is an extremely rare manifestation. In the elderly, anticoagulant treatment is frequent and bleeding symptoms are usually associated with this.

C3G promotes a selective release of angiogenic factors from activated mouse platelets to regulate angiogenesis and tumor metastasis.

Previous observations indicated that C3G (RAPGEF1) promotes α-granule release, evidenced by the increase in P-selectin exposure on the platelet surface following its activation. The goal of the present study is to further characterize the potential function of C3G as a modulator of the platelet releasate and its implication in the regulation of angiogenesis. Proteomic analysis revealed a decreased secretion of anti-angiogenic factors from activated transgenic C3G and C3G∆Cat platelets.

Comparison of Different Bone Marrow-Derived Stem Cell Approaches in Reperfused STEMI. A Multicenter, Prospective, Randomized, Open-Labeled TECAM Trial.

Background: Stem cell-based therapy has emerged as a potential therapy in acute myocardial infarction (AMI). Although various approaches have been studied, intracoronary injection of bone marrow autologous mononuclear cells (BMMC) and the ability of granulocyte colony-stimulating factor (G-CSF) to mobilize endogenous cells have attracted the most attention.

Objectives: This study compares, for the first time, the efficacy of BMMC injection, G-CSF mobilization, and the combination of both with standard treatment.

Effect of telomere length on prognosis in men with acute coronary syndrome.

Telomere length is related to cellular aging and cardiovascular disease. Nevertheless, the specific role of cellular aging in this process is still unclear. The aim of this report was to analyze the prognostic value of telomere length in men admitted for acute coronary syndrome.

Prognostic value of telomere length in acute coronary syndrome.

Telomere and telomerase are involved in cellular and organismal ageing and have been related to human diseases. Coronary artery disease is one of the most common age-related health problems in developed countries. Nevertheless, the specific role of cellular ageing in this process is still unclear.

Analysis of incidence, risk factors and clinical outcome of thromboembolic and bleeding events in 431 allogeneic hematopoietic stem cell transplantation recipients.

Allogeneic hematopoietic stem cell transplantation recipients have an increasing risk of both hemorrhagic and thrombotic complications. However, the competing risks of two of these life-threatening complications in these complex patients have still not been well defined. We retrospectively analyzed data from 431 allogeneic transplantation recipients to identify the incidence, risk factors and mortality due to thrombosis and bleeding.

Risk of placenta-mediated pregnancy complications or pregnancy-related VTE in VTE-asymptomatic families of probands with VTE and heterozygosity for factor V Leiden or G20210 prothrombin mutation.

Background: Few studies have evaluated the risk of pregnancy-related adverse events in asymptomatic relatives of probands for VTE and factor V Leiden or the G20210A variant. The antepartum management of this population ranges from antepartum anticoagulation therapy to clinical surveillance.

Objective: To evaluate the risk of placenta-mediated pregnancy complications and pregnancy-related VTE in VTE-asymptomatic families of probands with VTE and who are heterozygous carriers of either factor V Leiden or PT-G20210A mutation.

[Hemodynamic and inflammatory markers of sleep apnea-hypopnea syndrome and nocturnal hypoxemia: effects of treatment with nasal continuous positive airway pressure].

Objective: In this study, we assessed factors associated with cardiovascular risk in patients with sleep apnea-hypopnea syndrome (SAHS) through analysis of plasma concentrations of N-terminal prohormone brain natriuretic peptide (NTproBNP) and high-sensitivity C-reactive protein (hsCRP). In addition, we analyzed the effect of nasal continuous positive airway pressure (nCPAP) on these markers.

Patients And Methods: Forty-two patients with SAHS (mild to moderate in 15 cases and severe in 27) were compared with 14 individuals without SAHS.

Identification of serum endoglin as a novel prognostic marker after acute myocardial infarction.

Endoglin is a proliferation-associated and hypoxia-inducible protein expressed in endothelial cells. The levels of soluble circulating endoglin and their prognostic significance in patients with acute myocardial infarction (AMI) are not known. In this observational prospective study serum endoglin levels were measured by ELISA in 183 AMI patients upon admission to hospital and 48 hrs later and in 72 healthy controls.

Homocysteine and outcome in young patients with acute coronary syndromes.

Background: Despite the well-known pro-thrombotic and pro-inflammatory plasma homocysteine effects, it remains uncertain whether these effects can be associated with an adverse cardiac outcome in young patients admitted with acute coronary syndromes.

Methods: Homocysteine levels were determined within 24 h after admission in 244 consecutive patients aged less than 56 years who presented with an acute coronary syndrome. We evaluated the relationship between homocysteine and both short-term (death, myocardial [re]infarction), and long-term prognosis (death, recurrent acute coronary syndrome and/or ischemic stroke), after 3.

Autologous skeletal myoblast transplantation in patients with nonacute myocardial infarction: 1-year follow-up.

Objective: To determine the feasibility and safety of skeletal myoblast transplantation in patients with chronic myocardial infarction undergoing coronary artery bypass grafting.

Methods: Twelve patients with a previous myocardial infarction and ischemic coronary artery disease underwent treatment with coronary artery bypass grafting surgery and intramyocardial injection of autologous skeletal myoblasts cultured with autologous serum. Global and regional cardiac function was assessed by echocardiogram.
