近期的临床研究表明 β受体阻滞剂特别是卡维地洛(Carvedilol)对包括心肌梗死和心绞痛的冠状动脉疾病 (CAD)病人的症状和预后均有益 ,体外实验也已证实卡维地洛为一有的抗氧化剂 ,但其抗氧化活性的重要性在临床背景中还未得到探索。作者假设 CAD病人内皮依赖性舒张功能可能通过 Recent clinical studies have shown that β-blockers, particularly Carvedilol, are beneficial for patients with coronary artery disease (CAD), including myocardial infarction and angina pectoris, both in their symptoms and prognosis. Carvedilol has also been demonstrated in vitro As an antioxidant, the importance of its antioxidant activity has not been explored in the clinical setting. The authors hypothesized that endothelium-dependent diastolic function may pass in CAD patients
