The medical saga of Vice President Dick Cheney demonstrates the remarkable progress in U.S. cardiovascular care over the past three decades. Implantable cardioverter defibrillators, like the one in Cheney, can successfully shock a damaged heart back to regular rhythm in eight seconds or so if a lethal rhythm begins.
A daily quandary for the cardiologist is in whom to implant such devices, as they are expensive ($30,000) and the indications about whom they will most help are quickly evolving. The Cheney case speaks volumes about physician judgment and patient access to therapy.
While ICDs have been around for 20 years, there still is only one clinical trial that speaks directly to Cheney's situation. It shows that ICDs improve survival in patients with heart conditions similar to Cheney's if used as a preventive tool. The recommendation of an ICD for Cheney is light years beyond what is being done in the general medical community. Of the 40,000 new ICDs implanted in the U.S. annually, almost all are for patients who have already been resuscitated after a cardiac arrest. Only 5% to 10% now are for the preventive indications used in the Cheney case.
It helps to be a high profile patient. Cheney had his problem identified and was in the hospital the next weekend. Where was the primary care physician in the decision-making process, unless it was the widely quoted chief of medicine at George Washington University Hospital? Was there a managed care official involved, or was President Bush standing in for the HMO when he said that he thought the procedure was a good idea?
