  2. 1. Coronary Reactive Hyperemia

    Author : Göran Olivecrona; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Medicin människa och djur ; Medicine human and vertebrates ; t-PA; P2Y1-receptors; Hypothermia; Coronary; Reactive hyperemia;

    Abstract : 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. READ MORE

  5. 3. Receptor Upregulation and MAPK Activity in Arteries and Bronchi Following Secondhand Smoke Exposure

    Author : Lei Cao; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary arteries; cerebral arteries; 5-hydroxytryptamine receptor; endothelin receptor; secondhand smoke exposure; bronchi;

    Abstract : 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. READ MORE

  6. 4. Insight into coronary artery ectasia

    Author : Usama Boles; Michael Y. Henein; Peter Eriksson; Corrado Tamurino; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary artery ectasia; atherosclerosis; acute coronary syndrome; lipidomic profile; cytokines; prognosis of coronary artery ectasia; kardiologi; Cardiology;

    Abstract : 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. READ MORE

  7. 5. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies

    Author : Gylfi Oskarsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Pediatri; Cardiovascular system; Kardiovaskulära systemet; fetal asphyxia; transposition of the great arteries; dilated cardiomyopathy; aortic stenosis; child; neonate; adenosine; coronary flow reserve; Doppler; coronary flow;

    Abstract : 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. READ MORE
