Angiography is indeed indicated in stable angina patients under specific conditions, such as when clinical risk models or international guidelines establish a high pre-test probability of obstructive coronary artery disease.
The retrieved literature consistently supports the claim that invasive coronary angiography in stable angina or chronic coronary syndromes is guided by specific clinical indications, risk models, and international guidelines rather than being used indiscriminately. Papers 0, 2, and 9 specifically discuss the tailored selection criteria, pre-test probability models, and guideline recommendations that govern when angiography is clinically indicated for stable patients.
