  1. 1. Atrial Fibrillation after Coronary Artery Bypass Surgery : A Study of Causes and Risk Factors

    Författare :Lena Jidéus; Dan Lindblom; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Atrial fibrillation; catecholamines; coronary artery bypass surgery; heart rate variability; neuropeptides; premature atrial contraction; thoracic epidural anaesthesia; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Sammanfattning : The aim was to study pathophysiological mechanisms and risk factors for developing atrial fibrillation (AF) after coronary artery bypass grafting (CABG), and the effect of thoracic epidural anaesthesia (TEA).The study comprised 141 patients undergoing CABG, including 45 patients randomised for TEA intra- and postoperatively.

  2. 2. Ventricular Long Axis Function: Amplitudes and Timings : Echocardiographic Studies in Health and Disease

    Författare :Frederick Bukachi; Anders Waldenstrom; Derek Gibson; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler Tissue Imaging; Ageing; coronary disease; left ventricular function; atrial contraction; electromechanical function; coronary angioplasty.; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: The ageing process not only increases the risk of coronary artery disease (CAD) but also complicates its diagnosis and treatment. It is therefore important to understand the newer concepts of cardiovascular ageing physiology as well as methods of predicting the outcomes of therapeutic options available for the elderly with severe CAD.

  3. 3. Right heart function in health and disease : a doppler echocardiography and doppler tissue imaging study

    Författare :Per Lindqvist; Elsadig E Kazzam; Anders Waldenström; Lars Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler tissue imaging; right ventricle; cardiac catheterisation; isovolumic relaxation; isovolumic contraction; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: It is well known that performance of the right ventricle (RV) determines exercise capacity and may confer prognostic information in different cardiopulmonary diseases. To allow optimal patient management, ideal methods to assess right heart function are therefore important. LÄS MER

  4. 4. Detection of paroxysmal atrial fibrillation : with special emphasis on intermittent ECG recording

    Författare :Peter Doliwa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained form of arrhythmia, affecting approximately 3 % of the adult population. AF may be symptomatic or asymptomatic. Asymptomatic paroxysmal atrial fibrillation (PAF) can be troublesome to diagnose, as most devices for arrhythmia detection provide only limited insight into heart rhythm. LÄS MER

  5. 5. Atrial fibrillation and its association to cardiac function and structure in cardiovascular disease

    Författare :David Waldenhjort; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Title: Atrial fibrillation and its association to cardiac function and structure in cardiovascular disease Aim: To study associations between atrial fibrillation (AF) and echocardiographic measures of left atrial (LA) and left ventricular (LV) parameters in patients with underlying cardiovascular disease. Hypothesis: LA and LV dysfunction can predict AF in heart failure (HF) or ischemic stroke. LÄS MER
