    The ADP receptor P2Y1 mediates t-PA release in pigs during cardiac ischemia

    The endothelial ADP receptor P2Y1 is responsible for a large part of the reactive hyperemia following cardiac ischemia. Tissue plasminogen activator (t-PA) increases during reactive hyperemia. We postulated that ...

    Mild hypothermia reduces cardiac post-ischemic reactive hyperemia

    In experimentally induced myocardial infarction, mild hypothermia (33–35°C) is beneficial if applied prior to ischemia or reperfusion. Hypothermia, when applied after reperfusion seems to confer little or no b...

    Coronary artery reperfusion: The ADP receptor P2Y1 mediates early reactive hyperemia in vivo in pigs

    The physiological mechanisms that regulate reactive hyperemia are not fully understood. We postulated that the endothelial P2Y1 receptor that release vasodilatory factors in response to ADP might play a vital rol...
