The cardiovascular effects of sevoflurane are similar to those of isoflurane with some minor exceptions. In contrast to isoflurane and particularly to desflurane, sevoflurane has not been associated with increases in heart rate in healthy volunteers and in patients. The coronary vasodilatory potency of sevoflurane appears to be lower than that of isoflurane and it has not been associated with a reduction of blood flow to collateral myocardium in dogs with steal-prone anatomy. In several multi-center studies of patients with coronary artery disease or at high risk for coronary artery disease receiving either sevoflurane or isoflurane for either cardiac or non-cardiac surgery, the incidence of myocardial ischemia and infarction did not differ between treatment groups. In both human and animal models, sevoflurane preserves cerebral blood flow and reduces cerebral metabolic rate, much like isoflurane.
七氟烷的心血管效应与异氟烷相似,仅有一些小的例外。与异氟烷尤其是地氟烷不同,七氟烷在健康志愿者和患者中并未导致心率增加。七氟烷的冠状动脉扩张效力似乎低于异氟烷,并且在具有易发生窃血解剖结构的犬中,它与侧支心肌血流量减少无关。在多项针对患有冠状动脉疾病或有冠状动脉疾病高风险的患者进行的多中心研究中,这些患者在心脏或非心脏手术中接受七氟烷或异氟烷麻醉,治疗组之间心肌缺血和梗死的发生率并无差异。在人和动物模型中,七氟烷都能维持脑血流量并降低脑代谢率,这与异氟烷非常相似。
