I also question my cardiologist judgement. So I took the CT scan which showed a aortic aneurysm on my heart which was pretty large but the cardiologist said we will watch it. I took it to my Vascular surgeon specialist and he said go back to the cardiologist and tell him of your concern and that you want to be proactive . If he doesn’t listen to you call and tell us and we will change his mind it’s to big and could go anytime. I also just read that Low Magnesium levels can increase the calcification in your arteries? I am now looking to get confirmation of that. I need to lower that level my blood is saturated with calcium.
