Thanks for writing to us.
A serum creatinine
of 1.9 mg% (if stable, means it was not a transient rise) definitely indicates significant damage to kidneys. Although neither this is a contraindication to heart surgery , nor it is an end stage kidney failure. but the risk of any intervention or surgery will be higher than those with normal kidney function. i would request you to wait for the repeat levels of serum cratinine. if they also come high, discuss the , management, risk and prognosis of your patient with your treating doctor (cardiologist and nephrologist
both) and then decide accordingly.
