A 52-year-old male from rural Maharashtra with no prior medical history presents to a primary health centre with chest discomfort for 2 hours. He is conscious, BP 145/92 mmHg, HR 88/min, RR 18/min. No dyspnoea. Physical examination is unremarkable. The health worker performs a 12-lead ECG which shows ST elevation in leads II, III, aVF. The nearest PCI-capable centre is 120 km away (3–4 hours by road). What is the most appropriate immediate next step?

Explanation

## Clinical Context This is an acute STEMI (inferior wall) in a resource-limited setting with significant distance from a PCI centre. The time-to-PCI exceeds the 120-minute window, making fibrinolytic therapy the guideline-recommended reperfusion strategy. ## Key Point: **In India, when PCI-capable centre is >120 minutes away, fibrinolytic therapy (streptokinase or tenecteplase) should be administered immediately at the point of first medical contact (PFMC), even in a PHC.** This is endorsed by the Indian College of Cardiology and ACC/AHA guidelines for STEMI management in resource-limited settings. ## Rationale for Correct Answer 1. **Dual antiplatelet therapy (aspirin + clopidogrel)** is given to all STEMI patients regardless of reperfusion strategy. 2. **Streptokinase 1.5 million units IV over 60 minutes** is the fibrinolytic agent of choice in India due to cost-effectiveness and availability. 3. **Time is myocardium:** Door-to-needle time for fibrinolysis should be <30 minutes. Delaying for transfer (3–4 hours) would result in myocardial loss. 4. **Contraindications to fibrinolysis** (absolute: active bleeding, recent surgery, intracranial pathology; relative: uncontrolled hypertension, recent trauma) are absent in this patient. ## High-Yield: **Fibrinolytic therapy reduces mortality by ~25% when given within 12 hours of symptom onset; benefit is greatest within 3 hours. In rural India, PHC-level thrombolysis saves more lives than delayed PCI.** ## Clinical Pearl: After fibrinolysis, if reperfusion is achieved (chest pain relief, ST resolution, arrhythmia cessation), the patient should still be transferred to a PCI centre for coronary angiography within 24 hours (rescue PCI if fibrinolysis fails, or elective angiography if successful). ## Comparison Table: Reperfusion Strategy Selection | Factor | PCI | Fibrinolysis | | --- | --- | --- | | **Time-to-reperfusion** | <90 min from PFMC | <30 min from PFMC | | **Mortality reduction** | 25–30% | 25% | | **Reinfarction rate** | Lower | Higher | | **Intracranial haemorrhage** | Rare | 0.5–0.9% | | **Suitable when PCI >120 min away** | No | Yes | | **Resource requirement** | Cathlab, trained team | Drugs, IV access | [cite:ACC/AHA STEMI Guidelines 2013, Indian College of Cardiology Consensus]
