A 60-year-old male asked:

cardiology resubmit #: does a cta-radiation and dye exam of the heart raise the heart rate to its maximum level like a stress threadmill exam would?

No: Not at all. In fact the patient may receive medications to slow down the heart. Slower heart rates result in more accurate imaging.
Dr. Dipesh Pokharel
Cardiology 17 years experience
No: No, CTA actually looks at heart artery itself (structure of heart at rest). Treadmill Stress increases heart rate to see if there is compromise to blood flow to the heart.
Dr. Frank Amico Jr
Internal Medicine 11 years experience
No: No, in fact you want the heart to be slower when undergoing a CTA. It allows better visualization of the coronary arteries.
