1. Assessment of Pulmonary Blood Flow in Heart Failure. Using Novel and Non-Invasive Diagnostic Methods
Sammanfattning : In heart failure (HF), the heart is unable to pump effectively in order to satisfy the demands of the body. The elevated filling pressure seen in HF leads to accumulation of fluid in the lungs, i.e pulmonary congestion. While investigation with chest X-ray is recommended, it has limitations in detecting pulmonary congestion. LÄS MER
2. Tomographic ventilation-perfusion lung scintigraphy in cardiopulmonary disease
Sammanfattning : Respiration relies, among other things, on the balance between regional ventilation and perfusion in the lungs. There are many cardiopulmonary diseases, such as pulmonary embolism (PE), chronic obstructive pulmonary disease (COPD) and left heart failure (LHF), which can affect respiration negatively. LÄS MER
3. Dysfunctional but viable myocardium - ischemic heart disease assessed by magnetic resonance imaging and single photon emission computed tomography
Sammanfattning : The assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. LÄS MER
4. Preoperative localisation of parathyroid adenoma in primary hyperparathyroidism using 99mTc-sestamibi SPECT/CT : an evolving scanning protocol
Sammanfattning : Primary hyperparathyroidism (pHPT) is caused by one or more hyperfunctional parathyroid gland causing an inappropriately high release of parathyroid hormone (PTH) in relation to the calcium concentration in the blood. PTH acts on the bones to release more calcium and on the kidneys to reabsorb calcium, causing hypercalcemia. LÄS MER
5. Blood pressure, blood pressure variability and myocardial ischemia : studies in patients with peripheral arterial disease and matched control subjects
Sammanfattning : Background: Patients presenting with peripheral arterial disease (PAD) often have concomitant coronary artery disease (CAD), which is frequently asymptomatic. Ambulatory blood pressure (ABP) monitoring improves risk stratification in hypertensive patients beyond that offered by office BP(OBP) measurements. LÄS MER
