Özet:

In the last three decades also in our country there has been a huge growth in the use of non-invasive testing for diagnosis of coronary artery disease (CAD). Therefore, appropriateness of prescription in diagnostic testing is crucial. Clinical evaluation is mandatory before a diagnostic test, including the evaluation of pre-test probability of the disease based on symptoms, age, sex and cardiovascular risk factors. The main benefit of testing is in patients with an intermediate pre-test probability. Testing for diagnosis of CAD is rarely appropriate in asymptomatic subjects, except for electrocardiogram exercise test in intermediate and high risk individuals, while stress or anatomic imaging is preferable in higher risk individuals. Coronary calcium score should not be used as screening test in asymptomatic subjects, except for excluding CAD in those with low pre-test probability. As far as diabetic patients are concerned, available evidence indicates an unfavorable risk-benefit ratio of extensive CAD screening, except in the presence of high clinical suspicion.
