For many people diagnosed with blocked heart arteries, getting a stent is a turning point. The procedure, known as angioplasty with stenting, can quickly restore blood flow, relieve chest pain, and, in many cases, save a person's life during a heart attack. After the procedure, many patients feel better and assume that their heart problem has been permanently fixed. However, cardiologists say this is one of the biggest myths surrounding heart disease. While a stent treats the blocked artery responsible for symptoms or a heart attack, it does not cure coronary artery disease. The disease that causes plaque to build up inside the arteries continues unless patients actively manage their risk factors. Read Full Story According to Dr Anshul Kumar Jain, Director – Cardiology at CK Birla Hospital, Delhi, a stent should be viewed as one part of treatment rather than a permanent solution. "A stent acts like a small metal scaffold that opens a clogged section of the artery, allowing blood to flow freely again.
However, it cannot stop the underlying process of plaque buildup. If risk factors such as smoking, uncontrolled diabetes, high cholesterol, unhealthy eating habits or poor medication adherence continue, new blockages can develop over time," he explains. Doctors often compare coronary arteries to household plumbing. A stent opens one blocked section of the pipe, but if unhealthy material continues flowing through the system, other parts can eventually become blocked as well. WHY CAN A HEART ATTACK HAPPEN AFTER A STENT? Although modern stents are highly effective, another heart attack is still possible for several reasons. One reason is restenosis, where scar tissue gradually forms inside the stent, causing the artery to narrow again. While newer drug-eluting stents have significantly reduced this risk, it can still occur in some patients. Another serious complication is stent thrombosis, in which a blood clot forms inside the stent. This is uncommon but can be life-threatening. It is more likely to happen if patients stop taking their prescribed blood-thinning (antiplatelet) medicines without consulting their doctor.
In addition, coronary artery disease is a progressive condition. Even if the stented artery remains open, new fatty deposits can build up in other heart arteries, leading to fresh blockages and increasing the risk of another heart attack. HOW CAN YOU LOWER THE RISK? The good news is that patients can significantly reduce their chances of another heart attack by following their treatment plan. Doctors recommend Taking all prescribed medications regularly, especially antiplatelet drugs and cholesterol-lowering medicines. Quitting smoking completely. Eating a balanced, heart-healthy diet low in saturated fats and processed foods. Exercising regularly after getting clearance from a doctor. Maintaining a healthy weight. Keeping diabetes, blood pressure and cholesterol under control. Attending regular follow-up appointments with a cardiologist. These measures not only protect the stented artery but also help prevent blockages elsewhere in the heart. DON'T IGNORE THESE WARNING SIGNS Even after a successful angioplasty, patients should remain alert for symptoms that could signal another heart problem.
