May 11, 2021 Those flimsy, wallet-sized pieces of paper that detail the type, size, and location of the stent implanted? After roughly 4 years after device implantation, just under half of patients still carry their stent card, according to a new study. And even among those diligent card-carrying members of the coronary stent club, patients had very little knowledge about the device propping open their arteries. In fact, only 17% of patients with a stent card were able to correctly identify the date of the procedure, the vessel stented, and the type of stent they received, say researchers. For one cardiologist, the continued reliance on paper stent cards doesn’t make much sense. Computers, cellular phones, and app-based technology would go a long way toward eliminating the need for patients to carry around the card, especially since half aren’t doing so anyway.
