ABSTRACT

Speckle-tracking echocardiography has enabled clinicians to detect changes in myocardial function with more sensitivity than that afforded by traditional diastolic and systolic functional measurements, including left ventricular ejection fraction. Speckle-tracking echocardiography enables evaluation of myocardial strain in terms of strain (percent change in length of a myocardial segment relative to its length at baseline) and strain rate (strain per unit of time). Both measurements have potential for use in diagnosing and monitoring the cardiovascular side effects of cancer therapy. Regional and global strain measurements can independently predict outcomes not only in patients who experience cardiovascular complications of cancer and cancer therapy, but also in patients with a variety of other clinical conditions. This review and case series examine the clinical applications and overall usefulness of speckle-tracking echocardiography in cardio-oncology and, more broadly, in clinical cardiology.

Cardio-oncology discipline: focus on the necessities in developing countries

Alizadehasl A, et al. ESC Heart Fail 2020 - Review.

ABSTRACT

Cardiovascular diseases constitute one of the main aetiologies of mortality among patients with cancer. Population ageing and cancer survival rate improvements have resulted in the coexistence of cardiovascular diseases and malignancies in an increasing number of patients. With the diversity in treatments and the introduction of new drug lines, multiple mechanisms of cardiovascular injury have been recognized in these patients. Cardio-oncology is an emerging entity introduced to provide a proper solution to the several challenges encountered in the management of patients with cancer and cardiac involvement. This review will assess the logical grounds for establishing a cardio-oncology unit, describe the main objectives and the detailed responsibilities in such systems, and outline the target population. Furthermore, the importance of research and appropriate data collection will be highlighted. Lastly, the special considerations and modifications required for setting up such centres in the developing countries are discussed.

Primary pericardial angiosarcoma: case report and review of treatment options

Yadav U and Mangla A. Ecancermedicalscience 2020.

ABSTRACT

A primary cardiac angiosarcoma is a rare type of soft-tissue sarcoma with a high mortality rate. This report describes a young woman who presented with chest pain and worsening shortness of breath over the course of a year. She was diagnosed with and treated for latent tuberculosis and autoimmune pericarditis over the last year, however, her condition kept worsening. Further workup revealed a large pericardial and right atrial mass associated with multiple lung nodules. The biopsy from the lung mass showed angiosarcoma, and she was diagnosed with primary metastatic angiosarcoma of the pericardium. She was treated with doxorubicin and Ifosfamide (AIM-75 regimen), which led to a partial response. However, soon after completion of six cycles, the tumour progressed rapidly, leading to cardio-respiratory failure. In this report, we will discuss the clinical challenges and treatment options (surgical and medical) that are available for treating patients with angiosarcoma of the heart.

Randomised controlled trial comparing efficacy and safety of high versus low Low-Molecular Weight Heparin dosages in hospitalized patients with severe COVID-19 pneumonia and coagulopathy not requiring invasive mechanical ventilation (COVID-19 HD): a structured summary of a study protocol

Marietta M, et al. Trials 2020. ABSTRACTOBJECTIVES: To assess whether high doses of Low Molecular Weight Heparin (LMWH) (i.e. Enoxaparin 70 IU/kg twice daily) compared to standard prophylactic dose (i.e., Enoxaparin 4000 IU once day), in hospitalized patients with COVID19 not requiring Invasive Mechanical Ventilation [IMV], are: a)more effective in preventing clinical worsening, defined as the occurrence of at least one of the following events, whichever comes first: 1.Death2.Acute Myocardial Infarction [AMI]3.Objectively confirmed, symptomatic arterial or venous thromboembolism [TE]4.Need of either: a.Continuous Positive Airway Pressure (Cpap) or Non-Invasive Ventilation (NIV) orb.IMV in patients who at randomisation were receiving standard oxygen therapy5.IMV in patients who at randomisation were receiving non-invasive mechanical ventilationb)Similar in terms of major bleeding risk TRIAL DESIGN: Multicentre, randomised controlled, superiority, open label, parallel group, two arms (1:1 ratio), in-hospital study.

PARTICIPANTS: Inpatients will be recruited from 7 Italian Academic and non-Academic Internal Medicine Units, 2 Infectious Disease Units and 1 Respiratory Disease Unit.

INCLUSION CRITERIA (ALL REQUIRED): 1. Age > 18 and < 80 years 2. Positive SARS-CoV-2 diagnostic (on pharyngeal swab of deep airways material) 3. Severe pneumonia defined by the presence of at least one of the following criteria: a.Respiratory Rate ≥25 breaths /minb.Arterial oxygen saturation≤93% at rest on ambient airc.PaO2/FiO2 ≤300 mmHg 4. Coagulopathy, defined by the presence of at least one of the following criteria: a.D-dimer >4 times the upper level of normal reference rangeb.Sepsis-Induced Coagulopathy (SIC) score >4 5. No need of IMV EXCLUSION CRITERIA: 1. Age <1880 years 2. IMV 3. Thrombocytopenia (platelet count < 80.000 mm3) 4. Coagulopathy: INR >1.5, aPTT ratio > 1.4 5. Impaired renal function (eGFR calculated by CKD-EPI Creatinine equation < 30 ml/min) 6. Known hypersensitivity to enoxaparin 7. History of heparin induced thrombocytopenia 8. Presence of an active bleeding or a pathology susceptible of bleeding in presence of anticoagulation (e.g. recent haemorrhagic stroke, peptic ulcer, malignant cancer at high risk of haemorrhage, recent neurosurgery or ophthalmic surgery, vascular aneurysms, arteriovenous malformations) 9. Concomitant anticoagulant treatment for other indications (e.g. atrial fibrillation, venous thromboembolism, prosthetic heart valves) 10. Concomitant double antiplatelet therapy 11. Administration of therapeutic doses of LMWH, fondaparinux, or unfractionated heparin (UFH) for more than 72 hours before randomization; prophylactic doses are allowed 12.

Presence of other severe diseases impairing life expectancy (e.g. patients are not expected to survive 28 days given their pre-existing medical condition) 14. Lack or withdrawal of informed consent INTERVENTION AND COMPARATOR: Control Group (Low-Dose LMWH): patients in this group will be administered Enoxaparin (Inhixa®) at standard prophylactic dose (i.e., 4000 UI subcutaneously once day). Intervention Group (High-Dose LMWH): patients in this group will be administered Enoxaparin (Inhixa®) at dose of 70 IU/kg every 12 hours, as reported in the following table. This dose is commonly used in Italy when a bridging strategy is required for [...]
