  1. 1. Coronary Reactive Hyperemia

    Författare :Göran Olivecrona; Kardiologi; []
    Nyckelord :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;

    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

  4. 3. Coronary artery bypass surgery without extracorporeal circulation

    Författare :Jenny Vedin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cardiopulmonary bypass; off pump; hemodynamics; myocardial damage; inflammation; hemostasis; cognitive function;

    Sammanfattning : Introduction: Coronary artery bypass surgery with extracorporeal circulation is associated with a systemic inflammatory response syndrome that contributes to morbidity and mortality. Aortic cross clamping and cardioplegic arrest induces an ischemic insult to the heart and is a risk factor for neurological injury. LÄS MER

    Författare :Elhadi Aburawi; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; cardiopulmonary bypass; transthoracic Doppler echocardiography; coronary flow; Pediatri; endothelial dysfunction; C-reactive protein; Medicin människa och djur ; Pediatrics; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Factors Affecting Coronary Flow in Children Elhadi H. Aburawi, MD, MSc, FRCPI, FRCPCH Division of Paediatric Cardiology, Department of Paediatrics, Lund University, Sweden Abstract Background: A number of inborn and exogenous factors influence the flow and function of the coronary arteries with possible consequences on the cardiovascular risk.

  7. 5. Cardiac Arrest – mechanical chest compressions, gender differences and coronary angiography

    Författare :Erik Lindgren; Sten Rubertsson; Theresa M Olasveengen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac arrest; OHCA; IHCA; CPR; coronary angiography; percutaneous coronary intervention; PCI; mechanical chest compressions; lucas; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Cardiac arrest is a major health problem with over 6000 cases of out-of-hospital cardiac arrest (OHCA) and 2500 cases of in-hospital cardiac arrest (IHCA) per year in Sweden. Survival are low. Many factors affect the chances of survival, including effective cardiopulmonary resuscitation and optimal post resuscitation care. LÄS MER
