心肌灌注顯像藥物負(fù)荷試驗(yàn)是針對(duì)臨床檢查中不能耐受運(yùn)動(dòng)試驗(yàn)的患者展開(kāi)的檢查。研究顯示腺苷A_2A受體激動(dòng)藥瑞加德松可以很好地避免傳統(tǒng)心肌缺血激發(fā)劑惡心、嘔吐、支氣管痙攣、呼吸困難、胸痛、頭痛等不良反應(yīng)，具有起效快、作用時(shí)間長(zhǎng)、效果穩(wěn)定、副作用小等優(yōu)點(diǎn)，且檢查時(shí)操作更加簡(jiǎn)便，已在國(guó)外市場(chǎng)得到了廣泛認(rèn)可，為心肌灌注顯像檢查提供很大幫助。就瑞加德松的藥理作用、臨床應(yīng)用特點(diǎn)、不良反應(yīng)等進(jìn)行綜述。

Myocardial perfusion imaging pharmacological stress test is an examination for patients who cannot tolerate exercise test in clinical examination. Studies indicate that adenosine both A 2Areceptor excited medicine regadenoson can be very good to avoid the traditional myocardial ischemia excitation agent nausea, vomiting, bronchospasm, adverse reactions such as difficulty breathing, chest pain, headache, has quick effect, long duration and stable effect, and the advantages of small side effects, and the operation of checking more convenient, it has been widely accepted in foreign markets, check for myocardial perfusion imaging provides a great value.
