Chest Pain and Cardiac Emergencies 2015

Chest Pain and Cardiac Emergencies Welcome Chest Pain Certainty Simulation

Introduction • Chest Pain is common – 6 potentially lethal causes to remember – Traditional approach (*full Hx) may be suboptimal • Assessment and Management should focus on – ABCDEFG and ECG – IV access, M. O. N. A. (may not be right anymore) – Senior review (#8500/mobile or Medical Registrar)

Approach – Traditional vs. Emergency Life Threats Serious Causes Benign Causes (Common)

Lethal Causes • • • Myocardial Infarction (MI) Pulmonary Embolism (PE) Aortic Dissection (AD) Pneumothorax (Tension Pneumothorax) Pneumonia and Sepsis Oesophageal Perforation

Myocardial Infarction and the Acute Coronary Syndromes ECG

ECG 1

Acute Coronary Syndrome Assessment

Assessment • Assessment – DETECT ABC approach • Pitfalls – Elderly Patients are often pain free – MI patients may have NO risk factors

Acute Coronary Syndromes (ACS) Acute Coronary Syndromes STEMI (30%) NSTEMI (25%) UAP (35%)

Atypical = Typical

Acute Coronary Syndrome Management

Management – MONA – 0. 1 mg/kg IV and reassessment – titrated to 94% (no longer routine) – with care (avoid in RV infarction) – have a high threshold for not giving – low NNT and good safety profile • Other (ABCDEFG) • • Morphine Oxygen Nitrate Aspirin – ACE Inhibitor, β Blockers, Clopidogrel & Prasugrel – Don’t ever forget glucose (BSL) – Fluids (often required in RV infarction)

Management • Resuscitation, Specific (MONA) and Supportive • Disposition – Catheter Laboratory – Cardiac Unit (A 5 a, A 5 c) – CCU (A 5 b) – Cardiothoracics (C 3 c and D 3 c) – Respiratory Ward - PE and Pneumothorax (B 5 a) – ICU (E 3 a and E 3 b) – Home & follow up (e. g. EST, Cardiac CT, MIBI, Echo)

Other Causes of Chest Pain

Pulmonary Embolism

Aortic Dissection • Uncommon 5/100, 000 • Overall Mortality is 27% in hospital, 1% per hour and >90% untreated • Ratio of MI to Dissection is 3000: 5 (so it is often missed and treated as MI) • Risk Factors – Hypertension, Cardiothoracic Surgery, Collagen Vascular Disease • Stanford – A & B (‘A’ proximal involvement) • CXR and BP both arms have limited value!

Pneumothorax

Arrhythmia Recognition and Management

Has the patient arrested? Perfusion No Pulse ALS Algorithm Pulse Assessment of Stability

Is the patient stable? Are there any adverse signs? Stability and Adverse Signs Extremes of Heart Rate *Blood Pressure and Perfusion Chest Pain Signs of Acute Heart Failure

Arrhythmias • The Mantra / Approach – How is the patient? What is the Cause? – IV, O 2, Monitor – Call for assistance • Assessment of Rhythm – Assessment of Pulse and Adverse Features – Narrow Complex vs. Broad Complex – Regular vs. Irregular – Slow, Fast vs. Very Fast

Causes of Bradycardia/Tachycardia? Drugs Ischaemia Electrolytes
