Is nuclear stress test or Cardiac CTA better for ruling out clogged arteries? My nuclear test was clear but they couldnt do CTA due to heart rate.

In brief: Nuclear stress test

The nuclear stress test is better because (1) it is a functional test - your heart is actually "stressed" to beat harder, & (2) you can do it at any heart rate (as you've seen).
The cardiac CTA only tells you anatomy - whether or not there is calcium in the arteries - not how your heart functions. Not all plaques contain calcium, either, so cardiac CTA has false negatives also. Talk to your doctor
