[The value of exercise test in acute coronary syndrome].
In general, exercise testing in acute coronary syndrome (ACS) has been used in the assessment of physical capacity and to obtain prognostic information. Within recent years, however, a number of randomized studies have addressed the role of exercise testing in identifying patients, who may benefit from an invasive versus a conservative treatment strategy. According to the literature, a normal exercise test result after ACS is associated with an excellent clinical outcome. Patients who for clinical reasons are unable to perform an exercise test comprise a high risk group for future cardiac events. An invasive strategy is warranted in patients who continue to have angina and exhibit significant ST-segment depression in the exercise-ecg or reversible defects on perfusion scintigraphy. Based on the results of a recent, large scale randomized study, patients with unstable angina or acute non-Q-wave infarction appear to benefit from an early invasive treatment strategy--regardless of the results of a preceding exercise test.
