  1. 11. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

    Författare :Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

    Sammanfattning : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). LÄS MER

  3. 12. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography

    Författare :Toomas Kangro; Uppsala universitet; []
    Nyckelord :Medical sciences; Arterial distensibility; diastole; Doppler echocardiography; exercise; healthy persons; hypertension; LV filling; menopause; medicin; vård; MEDICINE; MEDICIN; Clinical Physiology; Klinisk fysiologi;

    Sammanfattning : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. LÄS MER

  4. 13. Left ventricular remodeling and function in ischemic heart disease and aortic valve disease

    Författare :Jonas Jenner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Cardiac remodeling is a broad term that refers to structural and functional alterations of the heart in response to chronic changes in loading conditions or left ventricular (LV) contractile performance. Different loading conditions will affect the heart in different ways, some leading to impaired heart function, symptoms of heart failure, or even death. LÄS MER

  5. 14. Structural and neurohormonal factors in left ventricular hypertrophy and inhibition of the renin-angiotensin-aldosterone system

    Författare :Karin Malmqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Left ventricular hypertrophy; RAAS; insulin; sympathetic nervous system; leptin echocardiography; soluble cell adhesion molecules; AT1-recemor blockade; ACE inhibitor; QT dispersion;

    Sammanfattning : Hypertensive left ventricular hypertrophy (LVH) is a major risk factor for cardiovascular morbidity and mortality. The aim of this thesis was to study how different neurohormonal systems relate to left ventricular mass, and to study structural and functional cardiovascular changes in hypertensive LVH. LÄS MER

  7. 15. The endocrine heart - metabolic actions of atrial natriuretic peptide

    Författare :Amra Jujic; Kardiovaskulär forskning - hypertoni; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial natriuretic peptide; type 2 diabetes; rs5068; insulin resistance; glucose dependent insulinotropic peptide; glucagon-like peptide-1; left ventricular hypertrophy;

    Sammanfattning : Abstract The natriuretic peptides (NPs), namely atrial natriuretic peptide (ANP) and bran natriuretic peptide (BNP), which are secreted from cardiomyocytes in response to cardiac wall stress, play a significant role in the regulation of blood pressure, intravascular volume, and cardiac remodeling. Recently, NPs emerged as hormones with metabolic actions such as inhibition of the renin-angiotensin system and inhibition of inflammation, together with lipolysis and adipose tissue browning. LÄS MER
