The evaluation and management of heart disease in patients about to undergo noncardiac surgery begins with a careful history and physical examination, including an assessment of clinical risk for perioperative myocardial infarction and/or death. Patients can be categorized into major, intermediate, minor or low clinical risk groups, based on clinical markers such as past myocardial infarction, congestive heart failure, angina or diabetes. Additional evaluation includes estimation of surgery-specific risk, prior coronary evaluation and/or revascularization, and level of functional capacity. Based on these parameters, physicians can decide to engage in further noninvasive testing to assess left ventricular function and/or risk of perioperative ischemia in a small, selected group of patients. Rarely, patients may meet criteria for perioperative coronary revascularization followed by noncardiac surgery. Perioperative medical therapy relies heavily on the use of beta blockers. Postoperative cardiac surveillance must be tailored to the individual patient. The use of pulmonary arterial catheters, the type of anesthesia and the assessment of long-term cardiac risk are also discussed in this summary of the ACC/AHA Guidelines.
对于即将接受非心脏手术的患者,心脏病的评估与管理始于详细的病史询问和体格检查,包括对围手术期心肌梗死和/或死亡的临床风险评估。根据既往心肌梗死、充血性心力衰竭、心绞痛或糖尿病等临床指标,患者可分为高、中、低或极低临床风险组。进一步评估包括手术特定风险评估、既往冠状动脉评估和/或血运重建以及功能能力水平。基于这些参数,医生可决定对一小部分选定患者进行进一步的无创检查,以评估左心室功能和/或围手术期缺血风险。极少数情况下,患者可能符合围手术期冠状动脉血运重建后再行非心脏手术的标准。围手术期药物治疗严重依赖β受体阻滞剂的使用。术后心脏监测必须根据个体患者进行调整。本ACC/AHA指南总结中还讨论了肺动脉导管的使用、麻醉类型以及长期心脏风险评估。
