[Metha-analysis of results of stress-tests application in patients before the operations on peripheral vessels and abdominal aorta].
Results of meta-analysis of 90 publications concerning cardiac stress-tests carried out to patients before operations on vessels and abdominal aorta are presented; 11,778 patients were included in the system review. On the basis of literary data advantages and disadvantages of diverse diagnostic tests and contra-indications to them were analyzed. Findings prove that pharmacological stress-tests have the highest sensitivity and specificity. Out of various diagnostic tests--treadmill test with ECG control, Holter monitoring, radioisotope imaging with thallium-201, and dipyridamole, and stress-echocardiography with dobutamine--the last one is the most informative in predective value of positive result, relative risk of possibility development of negative cardiac event (myocardial infarction or patient's death in consequence of myocardial infarction), likelihood ratio, sensitivity and specificity. Furthermore, during stress-echocardiography with dobutamine examination of myocardial contractility and evaluation of ejection fraction are available what makes it a method of choice in cardiac risk stratification in patients before reconstructive vascular surgery.
