Do You Really Need a Stent? A Cardiologist Explains
Many patients feel anxious when their doctor recommends a stent. A very common question that comes up is: "Is it okay if I do not put a stent?" Dr. Nikhila Pachani, Consultant Interventional Cardiologist at Backbone Medicity Hospital, Rajkot, addresses this question directly — and the answer matters for your heart health.
What Happens When a Coronary Artery Gets Blocked?
Your heart needs a steady supply of blood to keep working. The coronary arteries are the blood vessels that deliver this supply. When one of these arteries develops a significant blockage and it is left untreated for a long time, two serious things can happen:
- Heart muscle damage – The part of your heart that is not getting enough blood slowly weakens or dies.
- Higher risk of a heart attack – A major blockage puts you at real risk of a sudden cardiac event.
The key word here is significant. Not every blockage automatically requires a stent. Your cardiologist will assess the severity using tests like a coronary angiography before recommending the right treatment.
How Does a Stent Help?
A stent is a small mesh tube placed inside a blocked artery during a procedure called angioplasty (also known as PTCA — Percutaneous Transluminal Coronary Angioplasty). Once the stent is placed, blood flow through the artery is restored almost immediately.
This quick restoration of normal blood circulation can help prevent serious complications such as:
- Cardiac arrest
- Arrhythmias (irregular heartbeat)
- Valvular leaks (damage to the heart valves caused by prolonged poor blood supply)
What Are the Alternatives?
In some cases, depending on the number of vessels involved and the patient's overall health, a doctor may recommend bypass surgery (CABG) instead of a stent. In milder cases, optimal medical therapy — a carefully managed combination of medicines and lifestyle changes — may be the chosen path. The right option is always decided after a thorough evaluation.
The Bottom Line
Leaving a significant coronary artery block untreated is not without risk. The decision to place a stent is never taken lightly — it is based on the size of the blockage, your symptoms, and your overall heart health. Understanding your options helps you make an informed choice alongside your doctor.
If you have been advised an angiography or are concerned about a heart blockage, speak with a qualified cardiologist to understand what treatment approach is right for you.
