This randomized, double-blind trial found that tissue plasminogen activator activity increased and plasminogen activator inhibitor-1 activity decreased significantly more with exercise during placebo treatment than during treatment with beta blockade. These results suggest that beta blockade blunts the fibrinolytic response to maximal exercise.
这项随机双盲试验发现,与β受体阻滞剂治疗期间相比,安慰剂治疗期间运动后组织纤溶酶原激活物活性显著增加,纤溶酶原激活物抑制剂-1活性显著降低。这些结果表明,β受体阻滞剂会减弱最大运动时的纤溶反应。
