Dear Doctor, My Mother aged 74 years old has some health issues. She is taking deep breath and has sweating. She is diabetic, has High BP Vertigo etc. She is taking medicine for above problems and kept her disease under control. I recently did Echocardiogram for her, and consulted Cardio. Now for the past 2 month She is taking deep breath, feeling dizzy and gets sweating. I am planning to get Heart CT Angio scan. Please advise whether Heart CT Angio scan is safe for my Mother as She is 74 years old? Please clarify.
