[Utility and limitations of the exercise stress test in medical outpatients: an update].

Exercise testing has remained a widely used test in clinical practice to detect and diagnose coronary artery disease, despite the possibility to use cardiac imaging. The indications and contraindications for exercise testing are well known. However, its limitations have to be kept in mind in order to adequately interpret its results. Although exercise testing allows also deriving prognostic data on cardiovascular morbidity and mortality, consensus papers do not recommend this test as a screening tool in cardiovascular prevention in asymptomatic subjects.
