Side Room Investigations:
- HGT: 6.2 mmol/L
- Haemoglobin: 13.5 g/dL
Assessment:
- Acute Myocardial Infarction
- Differential Diagnoses:
1. Aortic Dissection
2. Pulmonary Embolism
3. Pericarditis
Plan:
- Overall plan: Immediate cardiac workup. Administer aspirin, nitroglycerin, and morphine. Consult cardiology. Prepare for potential primary percutaneous coronary intervention (PCI). Admit to Coronary Care Unit (CCU).
- Recommended medications: Aspirin 300mg chewable stat, Glyceryl trinitrate (GTN) spray 2 puffs sublingually, Morphine 2-4mg IV as needed for pain, Ticagrelor 180mg loading dose, Heparin infusion as per protocol.
- General patient care advice: Advise patient to remain calm, limit movement, and report any changes in symptoms immediately. Provide emotional support.
- Danger signs that would prompt a return to the emergency department: Worsening chest pain despite medication, increasing shortness of breath, new onset of confusion or weakness, collapse.
- Follow-up recommendations: Cardiology follow-up post-discharge, lifestyle modifications including smoking cessation and dietary changes, cardiac rehabilitation programme referral.
Investigations:
- Results of basic blood work: Trop I 0.8 ng/mL (elevated), CK-MB 120 U/L (elevated), FBC, U&Es, LFTs within normal limits.
- Results of any imaging performed: Chest X-ray – clear lung fields, normal cardiac silhouette. No evidence of pneumothorax or pleural effusion.
- Electrocardiogram findings: ST elevation in leads II, III, aVF (inferior MI).
Final/Working Diagnosis:
- Final diagnosis
- Primary diagnosis: Acute Inferior Myocardial Infarction with supporting rationale of classic symptoms (crushing chest pain radiating to left arm), elevated cardiac biomarkers (Trop I, CK-MB), and characteristic ECG changes (ST elevation in inferior leads).
