Question 4: For patients with hypertension, what tests should be done to determine if there is damage to the heart, brain, kidneys and other organs? The heart just needs to have a cardiac ultrasound and ECG to see if there is poor blood supply or cardiac remodeling, electrical axis shift, etc. caused by hypertension. Brain is mainly CT or MR to determine if there is ischemic or hemorrhagic injury. The kidneys just need to do kidney ultrasound, kidney function, and urine routine to see.
