The diagnosis of coronary heart disease (CHD) as the cause of chest pain (or other anginal-type symptoms of cardiac origin) requires the use of a careful clinical history as well as additional investigation. Invasive coronary angiography is considered the "gold standard" for the diagnosis of CHD involving the epicardial coronary vessels, but it is limited by its invasive nature, attendant risks, lack of functional data, inability to assess the microcirculation, and cost. Invasive angiography is therefore indicated as the first diagnostic test for CHD only in select, high-risk patient populations (table 1) [1,2]. Computed tomography coronary angiography (CTCA), which can noninvasively image the epicardial coronary vessels, overcomes some of the risk associated with invasive angiography, but CTCA also has its own limitations (eg, lack of functional data, inability to assess the microcirculation, artifact). (See "Diagnostic approach to chest pain in adults", section on 'Evaluation' and "Noninvasive coronary imaging with cardiac computed tomography and cardiovascular magnetic resonance".)
The evaluation of patients presenting with chest pain or suspected CHD often includes non-invasive testing. Several tests are available clinically that vary in accuracy, availability, and cost. The optimal testing strategy, including the possible use of more than one test, differs according to the patient population [3,4]. (See "Selecting the optimal cardiac stress test".)
The use of stress testing for the diagnosis of obstructive CHD will be reviewed here. The overall approach to the patient who presents with chest pain, including those with known or suspected CHD, the advantages and limitations of the different stress testing modalities, and the use of stress testing for prognosis and management are discussed separately. (See "Diagnostic approach to chest pain in adults" and "Selecting the optimal cardiac stress test" and "Stress testing to determine prognosis of coronary heart disease".)
OUR APPROACH TO DIAGNOSTIC STRESS TESTING
Our approach to diagnostic stress testing varies with the pretest probability of disease, which is the estimate of the likelihood of coronary heart disease (CHD) based upon the age, gender, symptom characteristics, and clinical history prior to stress testing. Because pre-test probability of disease influences post-test likelihood of disease (figure 2B), we highly recommend that clinical assessment of pretest probability, based upon data from large studies, be made prior to testing (table 2). This estimate of pretest probability of CHD can then be used to determine the need for and the optimal initial diagnostic approach to testing in the patient with known or suspected CHD.
Estimating pretest probability — Several studies with varying methodologies have contributed to how the pretest probability of CHD is estimated [5-11]. As examples:
