Coronary stent appropriateness and decision making in India

Guide To Make Informed Decisions Last night, during a very insightful meeting of Renu and I with community members in Kolkata, several raised concerns that they are often unsure whether s STENT is being recommended for a solid, life saving reason or simply to drive the economic engine of hospitals and health systems? I reviewed the data from published literature and also from across India and am providing a summary below: There is a good research study (Patil et al. Indian Health Journal) that looked carefully at appropriateness of stenting procedures. Overall, stents done for documented , acute heart attacks were appropriate. However, when there is NOT an acute heart attack, almost 4 out of 5 times, indications for stenting were considered “uncertain”, with a lot of missing information to ensure that it was necessary. Overall when considering a stent, The single most important question: “Is this an emergency or not?” A) When a stent is often truly needed (usually urgent/lifesaving) If you are having a heart attack or an unstable situation—for example: * severe ongoing chest pain, * ECG changes suggesting a heart attack, * rising cardiac enzymes (troponin), * unstable blood pressure, breathlessness, dangerous rhythm, …then opening the blocked artery quickly can be lifesaving. In India’s registry data, a major indication for PCI is post-myocardial infarction, meaning many procedures are related to heart attacks. In these emergency situations, a stent is often the right call. B) When a stent may be optional (usually not urgent) If this is stable chest discomfort (for weeks/months), or a blockage found during testing, or you are currently stable in the hospital—then we slow down and decide carefully. Here’s the key message: In stable coronary disease, large studies showed that adding angioplasty/stenting to best medical therapy does not reduce long-term risk of death or heart attack as an initial strategy for most patients—though it can help symptoms in some people. So, in stable cases, a stent is mainly for: * symptom relief when medicines aren’t enough, and/or * high-risk anatomy or high-risk testing that suggests a dangerous situation. 3) Why do families feel confused? Because an angiogram can show a “blockage,” but a blockage that looks tight is not always the blockage that is truly limiting blood flow. That’s why in many stable cases, good cardiology practice is to confirm whether the narrowing is truly causing reduced blood flow—often using: * a stress test or imaging, and/or * “pressure wire” tests like FFR/iFR in the cath lab (your doctor may use different terms). 4) The “3-question checklist” I recommend before an elective (non-emergency) stent If this is not a heart attack emergency, you can politely ask: Question 1: “What problem are we solving—saving life, preventing heart attack, or mainly reducing symptoms?” In stable disease, the main benefit is often symptom improvement, not guaranteed prevention of future heart attacks. Question 2: “How do we know this blockage is the one causing ischemia?” Ask whether the decision is based on: * stress test evidence, or * FFR/iFR, or * other objective evidence—not only “it looks 80–90%.” Question 3: “Have we tried strong medical therapy first, unless there is a high-risk reason not to?” Many stable patients do very well with: * antiplatelet therapy if indicated, * cholesterol lowering (statin/other), * BP and diabetes control, * anti-anginal medicines, * lifestyle and cardiac rehab. 5) India-specific “cost and transparency” tip In India, the government introduced price ceilings for coronary stents to reduce overcharging. Parliamentary/government documents also discussed concerns about very high margins in the past. So it is reasonable to request: * an itemized estimate/bill, * the stent name/brand and MRPs/allowed price, and * documentation of the indication This is not about accusing anyone—it’s about informed consent and transparency. 6) When I strongly encourage a second opinion (if stable) If the situation is stable and you feel rushed, it’s okay to say: * “We respect your recommendation. Since this is not an emergency, we’d like a second opinion today/tomorrow.” That’s especially wise if: * you have no or minimal symptoms, or * no clear ischemia testing was done, or * multiple stents are proposed immediately without explaining the “why.” The Bottom Line If it’s a heart attack or unstable situation—stents often save lives If it’s stable disease—stents can help symptoms, but many people can be treated safely first with excellent medicines, and the decision should be guided by objective evidence and clear goals
