    Advances in dyslipidemia management for prevention of atherosclerosis: PCSK9 monoclonal antibody therapy and beyond.
    Cardiovasc Diagn Ther 2017 Apr;7(Suppl 1):S11-S20
    California Heart Associates, Fountain Valley, California, USA.
    In 2003, select families with familial hypercholesterolemia were first identified to have gain-of-function mutations for proprotein convertase subtilisin kexin type 9 (PCSK9) followed, in 2006, by the identification of those with lifelong low levels of LDL-C and lowered atherosclerotic cardiovascular disease (ASCVD) risk who had loss-of-function PCSK9 mutations. These discoveries led to the rapid development of PSCK9-targeted monoclonal antibody (PCSK9 mAb) therapies and, in 2015, 2 'fully-humanized' PCSK9 mAbs (alirocumab and evolocumab) were marketed in the United States, Europe, and other countries. In a wide range of high risk patients, with and without ASCVD, these PCSK9 mAbs, as once or twice monthly subcutaneous injections, potently reduce LDL-C 50-65% beyond levels achieved by maximally tolerated statin therapy; approximately one-third of patients achieve LDL-C levels <25 mg/dL.

    Cardiac Amyloidosis: Diagnosis and Treatment Strategies.
    Curr Oncol Rep 2017 Jul;19(7):46
    Division of Cardiology, Department of Medicine, Ronald Reagan UCLA Medical Center, Los Angeles, CA, USA.
    Cardiac amyloidosis in the United States is most often due to myocardial infiltration by immunoglobulin protein, such as in AL amyloidosis, or by the protein transthyretin, such as in hereditary and senile amyloidosis. Cardiac amyloidosis often portends a poor prognosis especially in patients with systemic AL amyloidosis. Despite better understanding of the pathophysiology of amyloid, many patients are still diagnosed late in the disease course. Read More

    T2 mapping and T2* imaging in heart failure.
    Heart Fail Rev 2017 May 11. Epub 2017 May 11.
    Cardiovascular Biomedical Research Unit, Royal Brompton Hospital, National Heart and Lung Institute, Imperial College, Sydney Street, London, SW3 6NP, UK.
    Cardiovascular magnetic resonance (CMR) is a versatile imaging modality that enables aetiological assessment and provides additional information to that of standard echocardiography in a significant proportion of patients with heart failure. In addition to highly accurate and reproducible assessment of ventricular volumes and replacement fibrosis, multiparametric mapping techniques have rapidly evolved to further expand the diagnostic and prognostic applications in various conditions ranging from acute inflammatory and ischaemic cardiomyopathy, to cardiac involvement in systemic diseases such as sarcoidosis and iron overload cardiomyopathy. In this review, we discuss the established role of T2* imaging and rapidly evolving clinical applications of myocardial T2 mapping as quantitative adjuncts to established qualitative imaging techniques.

    Fondazione G. Monasterio CNR - Regione Toscana, Pisa.
    The incidental finding of a cardiac or paracardiac mass constitutes for cardiologists a relevant diagnostic and therapeutic problem. In fact, although primary cardiac tumors are infrequently, metastases, as well as non-neoplastic masses and pseudomasses, are much more frequent. A key role is played by echocardiography, but the latter is not always nullifying. Read More

    [Speckle tracking echocardiography: a practical guide].
    G Ital Cardiol (Rome) 2017 Apr;18(4):253-269
    Laboratorio di Ecocardiografia, Ospedale San Raffaele, Milano.
    Speckle tracking echocardiography (STE) has recently emerged as a quantitative technique to accurately estimate myocardial function. By the analysis of the motion of speckles in the two-dimensional ultrasonic image, this technique allows a non-Doppler angle-independent objective analysis of myocardial deformation, with the possibility to quantify thickening, shortening and rotation dynamics of cardiac function. Since this technique does not require Doppler imaging, the analysis is relatively angle-independent and is marginally affected by cardiac in-plane motion artifacts. Read More

    Background: Coronary artery calcification (CAC) may impair diagnostic assessment of coronary computed tomography angiography (CTA). We determined whether CAC affects efficiency of coronary CTA in patients with suspected acute coronary syndrome (ACS).

    Methods And Results: This is a pooled analysis of ACRIN-PA (American College of Radiology Imaging Network-Pennsylvania) 4005 and the ROMICAT-II trial (Rule Out Myocardial Infarction/Ischemia Using Computer Assisted Tomography) comparing an initial coronary CTA strategy to standard of care in acute chest pain patients.

    Role of Bone Marrow Mononuclear Cell Seeding for Nanofiber Vascular Grafts.
    Tissue Eng Part A 2017 May 9. Epub 2017 May 9.
    Johns Hopkins School of Medicine, 1500, Cardiac Surgery, Baltimore, Maryland, United States ;
    Objective: Electrospinning is a promising technology that provides biodegradable nanofiber scaffolds for cardiovascular tissue engineering. However, success with these materials has been limited, and the optimal combination of scaffold parameters for a tissue-engineered vascular graft (TEVG) remains elusive. The purpose of the present study is to evaluate the effect of bone marrow mononuclear cell (BM-MNC) seeding in electrospun scaffolds to support the rational design of optimized TEVGs. Read More

    Heart-Shaped Bilateral Medullary Pyramidal Infarction as a Pathognomonic Finding of Anterior Spinal Artery Occlusion.

    Ventricular tachyarrhythmias include potentially lethal episodes of sustained ventricular tachycardia (VT) and ventricular fibrillation (VF) as well as hemodynamically tolerated ventricular ectopic activity. Sustained VT or VF may develop in the setting of acute myocardial infarction or as clinical sequelae of advanced cardiomyopathy. The incidence of these serious arrhythmias is estimated from retrospective and observational studies and registries of sudden cardiac arrest and sudden cardiac death. Read More

    Cortical brain volume abnormalities associated with few or multiple neuropsychiatric symptoms in Alzheimer's disease.
    PLoS One 2017 8;12(5):e0177169. Epub 2017 May 8.
    Old Age Research Group-PROTER, Institute and Department of Psychiatry, University of Sao Paulo, Sao Paulo, Brazil.
    New research on assessing neuropsychiatric manifestations of Alzheimer´s Disease (AD) involves grouping neuropsychiatric symptoms into syndromes. Yet this approach is limited by high inter-subject variability in neuropsychiatric symptoms and a relatively low degree of concordance across studies attempting to cluster neuropsychiatric symptoms into syndromes. An alternative strategy that involves dichotomizing AD subjects into those with few versus multiple neuropsychiatric symptoms is both consonant with real-world clinical practice and can contribute to understanding neurobiological underpinnings of neuropsychiatric symptoms in AD patients.

    When should we use contrast material in cardiac MRI?
    J Magn Reson Imaging 2017 May 8. Epub 2017 May 8.
    Department of Radiology, Leiden University Medical Center, Leiden, The Netherlands.
    At present, most of the cardiac magnetic resonance imaging (MRI) examinations rely on contrast-enhanced protocols, but noncontrast alternatives are emerging. Late gadolinium enhancement (LGE) imaging for the detection of myocardial scar can be considered the main cause for the embedding of cardiac MRI into the clinical routine. The novel noncontrast technique of native T1 mapping shows promise for tissue characterization in ischemic and nonischemic cardiomyopathy and may provide additional information over conventional LGE imaging.
