Blocked arteries, different solutions
Context: General Studies Paper III – Science and Technology; Internal Security and Disaster Management (health infrastructure); also useful in Ethics (case studies involving public health)
1. Definition and procedure
Aspect | Angioplasty | Bypass surgery |
Definition | A minimally invasive procedure to open narrowed or blocked coronary arteries. | A major surgery to create an alternate path for blood to flow around a blocked artery. |
Procedure | A balloon-tipped catheter is inserted into the narrowed artery; often a stent is placed. | A healthy blood vessel (from the leg, arm, or chest) is grafted to bypass the blocked coronary artery. |
2. Invasiveness and Recovery
Aspect | Angioplasty | Bypass surgery |
Invasiveness | Minimally invasive (done via catheter through groin or wrist). | Highly invasive (requires opening of the chest and heart-lung machine). |
Recovery Time | Short (days to a week). | Longer (4–6 weeks or more). |
3. Suitability and Risk
Aspect | Angioplasty | Bypass surgery |
Best For | 1–2 artery blockages, especially if localized. | Multiple blockages or diabetic patients with diffuse disease. |
Risk | Lower short-term risk; may need repeat procedures. | Higher short-term risk; longer-term solution. |
4. Cost and accessibility in India
- Angioplasty is more widely available in urban healthcare settings and can be performed quickly.
- Bypass surgery is resource-intensive, requiring specialized cardiothoracic surgery teams and ICU support.
5. Policy relevance
- Schemes like Ayushman Bharat PM-JAY include both procedures.
- Expansion of non-communicable disease (NCD) care infrastructure is crucial to reduce cardiovascular mortality.
- The role of Public-Private Partnerships (PPPs) and medical technology indigenisation is central.
Short questions (Prelims/GS Mains One-Liners)
- What is the purpose of a stent in angioplasty?
- Which type of surgery involves creating a graft to bypass blocked arteries?
- Name a national health scheme in India that covers cardiac surgeries.
Long questions (GS Mains)
- Compare and contrast angioplasty and bypass surgery in terms of procedure, cost, and suitability.
- What are the challenges in delivering advanced cardiac care in rural India? Suggest measures to bridge the gap.
Analytical/case-based questions (GS/Essay/Ethics)
- “While technology offers life-saving cardiac interventions, equitable access remains a challenge.” Discuss this in the context of rural-urban health disparity.
- Suppose a government hospital has limited resources and must choose between angioplasty and bypass surgery for a patient. How should such decisions be ethically and medically guided?
