BACKGROUND Mitral annular systolic displacement from M-mode echocardiography and velocity from tissue Doppler imaging reflect subendocardial longitudinal systolic LV performance and may precede radial abnormalities. The aim of this study is to evaluate the utility of mitral annular systolic displacement (D) and velocity (V) during dobutamine stress(More)
BACKGROUND Normal left anterior descending (LAD) coronary artery as determined by coronary angiography is considered not only to reflect normal angiography but also to correlate with normal anatomy and function. However, subjects who undergo coronary angiography may differ from those who do not need to have invasive evaluation even if their functional(More)
In the presence of severe stenosis, coronary artery flow may be reduced at rest. Recent advances in echocardiography have made non-invasive sampling of velocities in the left anterior descending coronary artery (LAD) possible. The aim of our study was to evaluate feasibility and capability of transthoracic Doppler to detect severe stenosis of the LAD. The(More)
BACKGROUND Right ventricular (RV) systolic performance is more difficult for evaluation compared to the left ventricle (LV). Despite differences in structure, RV myocardial fibers are in continuity with those of LV. The aim is assessment of the effects of LV wall motion abnormalities (WMA) on RV systolic function at rest and after stress. METHODS Fifty(More)
BACKGROUND The temporal behavior of the coronary microcirculation in acute myocardial infarction may affect outcome. Diastolic deceleration time and early systolic flow reversal derived from coronary artery blood flow velocity patterns reflect microcirculatory function. OBJECTIVES To assess left anterior descending coronary artery flow velocity patterns(More)
BACKGROUND Myocardial stunning is responsible for partially reversible left ventricular (LV) systolic dysfunction after successful primary percutaneous coronary intervention (PPCI) in patients with acute ST-elevation myocardial infarction (STEMI). AIM To test the hypothesis that early coronary blood flow (CBF) to LV systolic function ratios, as an(More)
UNLABELLED The treatment of choice in acute ST-elevation myocardial infarction (STEMI) is primary percutaneous coronary intervention (PPCI). Although, thrombolysis in myocardial infarction (TIMI) and myocardial blush grade (MBG) measures provide semi-quantitative flow evaluation after PPCI, serial and quantitative volumetric flow evaluation is still(More)
Objectives: C-reactive protein (CRP) blood levels are associated with atherosclerosis and increased incidence of coronary events. Aim: To evaluate the utility for risk stratification of very early blood CRP levels, during the first 6 hours after the onset of chest pain, in patients with acute myocardial infarction (AMI). Methods: 118 patients with AMI, 88(More)

Norwegian classrooms have become more diverse due to immigration from both European and non-European countries. This implies new challenges for teachers and teacher education. This research paper presents a study aimed at exploring and analysing student teachers’ professional development through exposure to international practicum in South Africa and how(More)
BACKGROUND Diastolic dysfunction precedes systolic dysfunction in patients with coronary artery disease. The aim of the study was to evaluate the effects of left ventricular (LV) wall motion abnormality (WMA) on diastolic LV and right ventricular (RV) function at rest and after stress. METHODS Fifty-nine subjects, 15 with LV-WMA (abnormal group) and 44(More)
