Diastolic stress test in the preoperative non-cardiac surgery examination

Preoperative examination of patients undergoing high-risk elective non-cardiac surgery requires identifying factors associated with both the type of surgery and comorbidity profile of each patient. Determination of clinically significant echocardiographic changes, even without severe symptoms, can contribute to a change in management or revision of scheduled date and surgery tactics. The aspects of defining echocardiographic criteria for potential postoperative cardiovascular complications, especially in asymptomatic patients with preserved left ventricular ejection fraction, are an important clinical problem. The diastolic stress test, a relatively new type of exercise testing, is currently an additional diagnostic tool to detect heart failure in patients without reduced ejection fraction. The prospects of using this method before non-cardiac surgery in patients with preserved left ventricular ejection fraction is discussed in this article.
