Kidney transplant? If not I am sorry
Answer:
A diastolic blood pressure is somewhere between people in their 90s and 60s its in older folks. Your coronary arteries are fed during the diastolic phase. If you have a low diastolic pressure, it means you have a low coronary artery pressure, and that means your heart is going to lack blood and oxygen.
Hope this helps?
