Anesthesiologists frequently see asymptomatic patients with diastolic dysfunction or heart failure for various surgeries. These patients typically show normal systolic function but abnormal diastolic parameters in their preoperative echocardiographic evaluations. The symptoms that are sometimes seen are similar to those of chronic obstructive pulmonary disease. Patients with diastolic dysfunction, and even with diastolic heart failure, have the potential to develop a hypertensive crisis or pulmonary congestion. Thus, in addition to conventional perioperative risk quantification, it may be important to consider the results of diastolic assessment for predicting the postoperative outcome and making better decisions. If anesthesiologists see female patients older than 70 years of age who have hypertension, diabetes, chronic renal disease, recent weight gain, or exercise intolerance, they should focus on the patient's diastologic echocardiography indicators such as left atrial enlargement or left ventricular hypertrophy. In addition, there is a need for perioperative strategies to mitigate diastolic dysfunction-related morbidity. Specifically, hypertension should be controlled, keeping pulse pressure below diastolic blood pressure, maintaining a sinus rhythm and normovolemia, and avoiding tachycardia and myocardial ischemia. There is no need to classify these diastolic dysfunction, but it is important to manage this condition to avoid worsening outcomes.
麻醉医生在各类手术中经常会遇到患有舒张功能障碍或心力衰竭的无症状患者。这些患者在术前超声心动图评估中通常表现为收缩功能正常,但舒张参数异常。有时出现的症状与慢性阻塞性肺疾病的症状相似。患有舒张功能障碍甚至舒张性心力衰竭的患者有可能发生高血压危象或肺充血。因此,除了传统的围手术期风险量化外,考虑舒张功能评估结果对于预测术后结果和做出更好的决策可能很重要。如果麻醉医生遇到年龄超过70岁、患有高血压、糖尿病、慢性肾病、近期体重增加或运动不耐受的女性患者,他们应关注患者的舒张期超声心动图指标,如左心房扩大或左心室肥厚。此外,需要采取围手术期策略来减轻与舒张功能障碍相关的发病率。具体而言,应控制高血压,使脉压低于舒张压,维持窦性心律和血容量正常,避免心动过速和心肌缺血。无需对这些舒张功能障碍进行分类,但管理这种情况以避免结果恶化很重要。
