Results
Overall,
at least 70% of patients gave positive responses regarding explanation,
benefit,
and physician trust regarding their cardiac exams.
70% of patients reported that the information they received regarding the general risks and benefits was sufficient.
A majority of the patients (79%) believed that the benefits from the exam always outweighed the risks of potential exposure to radiation. 73% of patients agreed that the radiation risk was acceptable if their physician recommended the study.
However, 39% of patients indicated that they were willing to undergo an imaging test with higher radiation exposure,
if the test results were expected to be more accurate.
This is significantly lower than compared to those who indicated that they were willing to undergo an imaging study involving radiation,
if their physician felt it was necessary (p<0.0001) (Fig.
3).
With regards to the accuracy of the test,
68.4% of patients believed that their cardiac imaging procedure has a 50% chance or more of correctly diagnosing a potential health condition.
A total of 71% of patients believed that their cardiac imaging test had a 50% chance or more of correctly diagnosing a significant blockage; however,
only 21% believed that their test had a 50% chance or more of correctly diagnosing the absence of a significant blockage.
Overall,
76% of patients believed that they had a 50% or more chance of having a significant blockage of one or more of their coronary arteries based on their personal history.
