However, it is unknown whether patients’ beliefs and preferences influence management decisions, and we aimed to answer this question. Based on interviews of 351 stable patients at Geisinger Health System newly referred for cardiac stress testing/coronary computed tomographic angiography (CTA) for suspected IHD, we found that patients with an accurate understanding of their initial test result were less likely to undergo follow-up tests/procedures if the initial test was negative and more likely to undergo follow-up tests/procedures if the initial test was positive.
