What is the accuracy of non-invasive techniques for diagnosing coronary artery disease?
The accuracy of non-invasive techniques for diagnosing coronary artery disease is variable depending on the technique used. According to a meta-analysis by Biagini et al. (2006), the accuracy of exercise electrocardiography is moderate to good, with sensitivities ranging from 73%-88%. Stress echocardiography has a higher accuracy, with sensitivities ranging from 82%-96%. Myocardial perfusion imaging and stress perfusion scintigraphy have also been found to have high accuracies, with sensitivities ranging from 87%-96%.
