Overuse of Cardiac Stents
What? Stop right there.
The patient has chronic renal failure, has low blood counts, was quite stable with no symptoms, was receiving a transfusion and the cardiologist wants to put in stents? There are so many things wrong with this story I wanted to scream.
First of all, the workup should first zero in on the GI tract and find out why the patient had lost blood. He was not experiencing any chest pain or tightness once he received blood and was feeling quite normal. The cardiologist didn't even seem to be considering what the cause of the anemia was and had not called in a GI consultant. Additionally, with compromised kidney function, an angiogram could put him into acute renal failure:
"Contrast nephropathy is a recognized complication after coronary angiography and intervention that has been associated with prolonged hospitalization and adverse clinical outcomes," write lead study author Jay Kay, MBBS, MRCP, from the University of Hong Kong in Aberdeen, and colleagues.
Not only was the workup and plan completely wrong, but I wanted to ask the cardiologist if he was even aware of the COURAGE study that has rocked the medical world. This large trial was published in The New England Journal of Medicine and presented at the 2007 Scientific Session of the American College of Cardiology. The results showed there was no difference in the outcome (death or new non fatal heart attack) between patients with stable angina who received cardiac stents and those who did not.
Every patient is different and large trials like COURAGE give us information with which to make decisions. Most patients think stents save their lives. Most patients have never heard of these trials and still depend upon their physician to make the decision about what is needed. In this case, the Cardiologist was making a really bad decision for my patient.
As the Internist, I am looking at the entire picture and trying to be the quarterback. I respect the roles of the receiver, the half back and the guards but each of them are looking only at one part of the play, while I am viewing the entire field. In this case a patient with a GI bleed (later found to be an ulcer), no signs of unstable angina and chronic renal failure should NOT have an angiogram or any invasive cardiac procedure.
I advised my patient to "just say no". When he did, the Cardiologist replied, "Don't blame me if you go home tomorrow and have a heart attack."
Just jaw dropping!
