Hello Ms. Shweta
Thanks for writing to us.
might have been planned because of the heart attack
Since we give a dye (ink) in angiography which it self can cause kidney damage, especially in old, female, diabetic subjects who already have compromised kidney functions (as suggested by a creatinine
of above 1.5mg% in case of your father), your doctors advised to hold angiography for a while. The possible cause of damage to kidney is high blood pressure
in your case. there are many other causes like diabetes, drugs etc.
Now you need to consult both the specialists; cardiologist and nephrologist
. Cardiologist will tell you about the necessity of doing an angiography in your father, its advantages and disadvantages. Nephrologist will tell you how to prevent further damage to kidneys, and if you chose to get an angiography done, then he will be taking care that the damage to kidneys by angiographic dye is reduced to minimum and if any damage occurs to kidney during angiography he will be available to manage.
i hope i cleared the scenario to you. feel free to discuss further.
