  1. 1. Echocardiography/Doppler for the evaluation of coronary artery function, left ventricular function and the relationship between early diastolic and systolic function

    Författare :Reidar Winter; Lund University.; Lunds universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary flow reserve; contrast echocardiography; early diastolic downward velocity; flow propagation velocity; colour M-mode; diastolic function; Echocardiography; Doppler; Kardiovaskulära systemet; Cardiovascular system;

    Sammanfattning : Two specific areas of development in echocardiography are assessment of left ventricular (LV) diastolic function and myocardial ischemia. This thesis describes echocardiographic methodology in these two areas. LÄS MER

  2. 2. Echocardiographic measurements at Takotsubo cardiomyopathy transient left ventricular dysfunction

    Detta är en avhandling från Örebro : Örebro university

    Författare :Micael Waldenborg; Örebro universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; takotsubo; annulus motion; cardiac autonomic function; broken heart; diastolic; ventricular mass; concentric wall motion; Medicine; Medicin; Biomedicin; Biomedicine;

    Sammanfattning : Takotsubo cardiomyopathy (TTC) is a disease characterized by transient left ventricular (LV) dysfunction and typical wall motion abnormalities in apical parts, without obvious signs of coronary influence. Due to its elusive natural cause and the lack of clarified pathology, further studies are needed. LÄS MER

  3. 3. Diastolic heart function in hypertension-induced left ventricular hypertrophy

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Clinical Sciences

    Författare :Richard Müller-Brunotte; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypertension; left ventricular hypertrophy; diastolic function; myocardial fibrosis; angiotensin II; echocardiography;

    Sammanfattning : Hypertensive left ventricular (LV) hypertrophy is an independent strong risk factor for cardiovascular morbidity and mortality. An abnormal diastolic relaxation in the absence of systolic impairment is often seen in patients with hypertension, whether LV hypertrophy is present or not. LÄS MER

  4. 4. Nitrates and Left Ventricular Dysfunction

    Detta är en avhandling från Erik Tingberg Department of Clinical Sciences, Lund Cardiology, Faculty of Medicine, Lund University, Sweden

    Författare :Erik Tingberg; Lund University.; Lunds universitet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid peroxidation; malondialdehyde; peptide; brain natriuretic peptide; left ventricular dysfunction; nitrates; acute myocardial infarction; heart failure; atrial natriuretic; diuretics; echocardiography; haemodynamic measurements; neurohumoral activation; diastolic dysfunction; Cardiovascular system; Medicin människa och djur ; Medicine human and vertebrates ; Kardiovaskulära systemet; oxidative stress; isoprostanes;

    Sammanfattning : Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. LÄS MER

  5. 5. Quantification of 4D Left Ventricular Blood Flow in Health and Disease

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jonatan Eriksson; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; relative pressure; 4D flow; quantification; turbulent kinetic energy; dilated cardiomyopathy; magnetic resonance imaging; physiology; cardiac function; diastolic dysfunction;

    Sammanfattning : The main function of the heart is to pump blood throughout the cardiovascular system by generating pressure differences created through volume changes. Although the main purpose of the heart and vessels is to lead the flowing blood throughout the body, clinical assessments of cardiac function are usually based on morphology, approximating the flow features by viewing the motion of the myocardium and vessels.
