Stent Choice: Are Your Preferences Heard?
"Unveiling the disconnect between patient values and medical decisions in coronary stenting."
Choosing the right coronary stent—a tiny mesh tube that props open clogged arteries—is a critical decision for individuals with heart disease. While doctors weigh factors like the severity of the blockage and the patient's overall health, a recent study highlights a concerning disconnect: are patient preferences truly being considered?
Published in Catheterization and Cardiovascular Interventions, the study by Quintar et al. investigated how patients prioritize various outcomes associated with different types of stents—drug-eluting stents (DES) and bare-metal stents (BMS). DES reduce the risk of artery re-narrowing but require longer-term use of anti-clotting medications. BMS, on the other hand, carry a higher risk of re-narrowing but require less medication.
The study revealed that while patients have distinct concerns—such as avoiding repeat procedures, minimizing medication costs, and reducing the risk of bleeding—these preferences often don't align with the type of stent they ultimately receive. This raises questions about the extent to which shared decision-making is truly happening in cardiology.
Preference vs. Practice: The Stent Selection Gap
In the Quintar et al. study, researchers surveyed 317 patients prior to diagnostic angiography, asking them to rate the importance of various potential consequences of stent choice. These included the need for repeat procedures, the number of daily medications, medication costs, risk of bleeding, and the need to delay future surgeries or dental work.
- 14.4% of patients ranked avoiding repeat procedures as their top priority.
- 20.6% prioritized other factors, such as medication burden or bleeding risk.
- A significant 65% considered avoiding repeat procedures as equally important to other concerns.
Empowering Patients: A Call for Shared Decision-Making
The study underscores the importance of actively involving patients in the stent selection process. As Dr. Blankenship points out, simply asking patients to rate the importance of general consequences isn't enough. Patients need clear, personalized information about the marginal risks and benefits of each stent type in their specific situation.
For instance, understanding the actual cost difference between DES (including the cost of longer-term anti-clotting medication) and BMS, or the precise increase in restenosis risk with BMS, is crucial for informed decision-making. Tools like PREDICT can help facilitate these conversations.
Ultimately, the goal is to move beyond a one-size-fits-all approach and ensure that stent choices reflect individual patient values and priorities. This requires open communication, a willingness to explore patient concerns, and a commitment to shared decision-making in interventional cardiology.
