Insights
Primary percutaneous coronary intervention (PCI) improves outcomes for ST-elevation myocardial infarction (STEMI). Addressing physician misconceptions about PCI and pharmacoinvasive (PI) strategies is crucial for timely treatment in India.
Area of Science:
- Cardiology
- Interventional Cardiology
- Public Health
Background:
- Primary percutaneous coronary intervention (PCI) is the standard treatment for ST-elevation myocardial infarction (STEMI).
- Timely access to PCI in India is hindered by physician misconceptions regarding risks, efficacy compared to thrombolysis, referral timing, and pharmacoinvasive (PI) strategies.
- Despite proven benefits, primary PCI utilization and timely STEMI reperfusion remain suboptimal in India.
Purpose of the Study:
- To highlight the critical role of primary PCI in STEMI management.
- To identify and address persistent myths and misconceptions among Indian primary care physicians that limit timely PCI referral.
- To emphasize the importance of pharmacoinvasive (PI) strategies as an alternative in resource-limited settings.
Main Methods:
- Review of existing evidence on primary PCI and pharmacoinvasive (PI) strategies in STEMI.
- Analysis of barriers to timely PCI access in the Indian healthcare context.
- Discussion of educational and systemic interventions to improve STEMI care.
Main Results:
- Primary PCI is safe and highly effective, significantly reducing mortality, reinfarction, and stroke compared to thrombolysis.
- Misconceptions regarding procedural risks, comparative effectiveness, and referral protocols impede optimal STEMI management.
- Pharmacoinvasive (PI) therapy offers comparable outcomes to primary PCI in settings where timely PCI is not feasible.
Conclusions:
- Overcoming physician misconceptions through targeted education and standardized protocols is essential for improving STEMI outcomes in India.
- Strengthening STEMI networks and promoting evidence-based reperfusion strategies, including primary PCI and PI, are critical.
- Optimizing reperfusion therapy requires addressing systemic delays and promoting the adoption of guideline-recommended treatments.
Abstract:
Primary percutaneous coronary intervention (PCI) is the gold standard for managing ST-elevation myocardial infarction (STEMI). However, in India, despite the availability of catheterization laboratories, timely access to PCI remains limited due to persistent myths and misconceptions among primary care physicians. Common misconceptions include exaggerated concerns about procedural risks, the belief that medical management or thrombolysis is equally effective, the assumption that patients must be fully stabilized before referral, and uncertainty regarding the role of pharmacoinvasive (PI) strategies. Evidence consistently demonstrates that primary PCI is both safe and highly effective, reducing mortality, reinfarction, and stroke compared with thrombolysis, with very low complication rates. Despite these proven benefits, only a small proportion of STEMI patients in India currently receive primary PCI. Significant delays in care also persist, with many patients reaching the hospital several hours after symptom onset. PI therapy has emerged as a pragmatic alternative when timely PCI cannot be achieved, offering outcomes comparable to primary PCI in resource-limited and geographically constrained settings. Addressing these misconceptions through targeted education, standardized protocols, and strengthened STEMI networks is essential to improve outcomes and optimize reperfusion therapy in India.
