1. Coronary Reactive Hyperemia
Sammanfattning : Introduction: The mechanism of post ischemic reactive hyperemia is still unknown but now thought to be multifactorial and perhaps involving purinergic signalling. Purines such as ATP and ADP have recently been discovered to play a vital role in the regulation of vascular tone. LÄS MER

3. Receptor Upregulation and MAPK Activity in Arteries and Bronchi Following Secondhand Smoke Exposure
Sammanfattning : Cigarette smoking is a major risk factor for cardiovascular and respiratory diseases. Contractile receptor changes have been observed in several vascular diseases. The intracellular mitogen activated protein kinase (MAPK) signaling pathways are suggested to be associated with receptor upregulation. LÄS MER
4. Insight into coronary artery ectasia
Sammanfattning : Background:Coronary artery ectasia (CAE) is defined as a diffuse dilatation of the epicardial coronary arteries exceeding 1.5 folds the diameter of the normal adjacent arterial segment and/ or the remaining non-dilated part of the same artery. (1) The incidence of CAE has been variably reported between different nations and ranges between 1. LÄS MER
5. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies
Sammanfattning : Heart diseases in children cause different combinations of myocardial hypertrophy, increased intra-ventricular pressures, volume overload and decreased oxygen saturation. This may affect basal coronary flow and the ability of the heart to maximally increase coronary flow. LÄS MER
