Cardiology

1. Acute Pulmonary Oedema

ICU / RESUS▸

Casualty: breathless, orthopnoea, rales, JVD, S3 gallop, bilateral pitting oedema; prior MI/HTN

ABCDE

Sit upright; oxygen only if SpO₂ <90% (target ≥90%) — routine high-flow O₂ not indicated; IV access + monitoring; GTN + IV furosemide; start CPAP/BiPAP early if SpO₂ <90% or RR >25 despite O₂; treat arrhythmia/ischaemia.

  1. Sit upright + Oxygen only if SpO₂ <90% (target ≥90%); routine high-flow O₂ not indicated; continuous oximeter
    ✓
  2. Initial orders: Furosemide 40 mg IV + Nitroglycerin (paste/IV) + O₂ if SpO₂ <90%; CXR, ECG, ABG. Natriuretic peptides aid diagnosis when uncertain (rule-out BNP <100, NT-proBNP <300 pg/mL) — but never delay treatment to wait for them in florid pulmonary oedema. Morphine no longer routine
    ✓
  3. Move clock 15–30 min: if urine made → improving. If NOT → check response at 2 h (urine output / spot urine Na); if inadequate, double the IV dose — do not redose blindly; recheck vitals q15–30 min
    ✓
  4. First test: ECG → if arrhythmia (VT/AFib/flutter) causing it → immediate synchronized cardioversion
    ✓
  5. Still not responding to preload reduction: add IV nitroglycerin; consult cardiology + critical care (CCS)
    ✓
  6. Max preload Rx + persistent hypoxia → ICU: Persistent hypoxia despite NIV → intubation. Inotropes (dobutamine) only if SBP <90 mm Hg WITH hypoperfusion; norepinephrine if shock
    ✓
Order set
  • Sit up; O₂ only if SpO₂ <90%
  • IV furosemide
  • GTN (paste/IV/infusion)
  • ECG + troponin
  • CXR portable
  • ABG/VBG

  • 1 hReassess oxygenation; escalate NIV → intubation if failing; dobutamine only if SBP <90 + hypoperfusion
  • 2–6 hFluid balance, electrolytes, response
Escalate / ICU
  • Persistent hypoxia despite max preload reduction
  • Needs inotrope/vasopressor (only if SBP <90 mm Hg with hypoperfusion)
  • NIV (CPAP/BiPAP) failure
  • Rising PaCO₂ / exhaustion → intubate
  • Cardiogenic shock
Criteria
AdmitAll acute pulmonary oedema
ICURefractory hypoxia, shock, or NIV failure
IntubateExhaustion, ↓GCS, or refractory hypoxaemia despite NIV
VentilateFailing oxygenation on max NIV
VasopressorsCardiogenic shock — noradrenaline ± inotrope
DischargeEuvolaemic on oral therapy, SpO₂ stable on air, cause addressed, HF meds started + follow-up
Never
  • Call cardiology early, but start treatment yourself — do not wait for them
Key
  • Most patients respond to preload reduction alone. Loop alt if furosemide absent = bumetanide/torsemide.
  • Start CPAP/BiPAP early if SpO₂ <90% or RR >25 despite O₂ — early therapy, not last rescue.
  • Early bedside echo (immediate if shock/arrest); identify precipitant.
  • Urine catheter + strict fluid balance; daily weights.
  • VTE thromboprophylaxis (LMWH) unless contraindicated.
  • Initiate/up-titrate GDMT before discharge (STRONG-HF, Class I-B); in-hospital SGLT2 inhibitor start is supported (EMPULSE).
  • Acetazolamide 500 mg IV daily may augment decongestion (ADVOR).

2. Congestive Heart Failure (chronic, systolic)

EMERGENCY▸

Ambulatory: exertional dyspnoea, orthopnoea, PND, S4, apical murmur→axilla, oedema; long-standing HTN

  1. Initial orders: ECG, CXR, transthoracic echo (only way to tell systolic vs diastolic; EF low = systolic)
    ✓
  2. Start — 4 pillars (mortality benefit): ARNI (sacubitril-valsartan) or ACE-inhibitor/ARB + β-blocker (metoprolol succinate/carvedilol/bisoprolol) + SGLT2 inhibitor (dapagliflozin/empagliflozin) + MRA (spironolactone/eplerenone)
    ✓
  3. Congestion / fluid overload → loop diuretic (furosemide) titrated to symptoms
    ✓
  4. Still symptomatic → add Digoxin — ↓ symptoms & hospitalizations, does NOT ↓ mortality
    ✓
  5. Still symptomatic + wide QRS → Biventricular pacemaker (CRT). EF <35% → ICD (↓ mortality, not symptoms) — despite ≥3 months of optimal GDMT (and >40 days post-MI)

Key
  • Mortality ↓: ACEi/ARB, β-blocker, spironolactone/eplerenone (SGLT2i now added).
  • HFpEF (preserved EF): SGLT2 inhibitor is Class 2a to reduce HF hospitalizations (empagliflozin 10 mg OD — EMPEROR-Preserved; dapagliflozin — DELIVER); manage congestion with diuretics and treat comorbidities (HTN, AF). Non-DHP CCB: avoid in HFrEF.

3. Acute Coronary Syndrome

ICU / RESUS▸

Casualty: crushing substernal chest pain; risk factors (HTN, smoking, dyslipidaemia)

ABCDE

Oxygen only if SpO₂ <90% (not routine); IV access, continuous ECG; aspirin + 2nd antiplatelet; analgesia; activate reperfusion.

Calculators:
  1. Initial orders: ECG (≤10 min) + Troponin; Aspirin 162–325 mg chewed immediately, then 75–100 mg daily + Nitroglycerin SL (morphine only for refractory pain — not routine)
    ✓
  2. Add 2nd antiplatelet: ticagrelor or prasugrel preferred over clopidogrel — DAPT unless high bleeding risk or on oral anticoagulation (then individualize)
    ✓
  3. Give also: β-blocker (metoprolol) — avoid if cardiogenic shock, acute HF, bradycardia, hypotension, or high-grade AV block; ACE inhibitor; high-intensity statin (atorvastatin 80 mg or rosuvastatin 20–40 mg); anticoagulation in both STEMI and NSTEMI — agent per reperfusion strategy (UFH with PCI/fibrinolysis; enoxaparin/fondaparinux in NSTEMI)
    ✓
  4. STEMI — reperfuse: Primary PCI preferred: FMC-to-device ≤90 min (≤120 min if transfer needed). If not achievable → fibrinolysis (tenecteplase preferred) up to 12 h from onset, door/FMC-to-needle ≤30 min, then routine angiography 2–24 h (pharmacoinvasive)
    ✓
  5. Fibrinolysis only for: STEMI (or true STEMI-equivalent — Sgarbossa/modified Sgarbossa criteria with clinical correlation in LBBB/paced rhythm) — NOT for NSTEMI. New LBBB alone is NOT an automatic STEMI equivalent.

6. Atrial Fibrillation

EMERGENCY▸

Irregularly irregular pulse, no P waves, rapid rate

Calculators:
  1. Unstable (chest pain, CHF, ↓SBP, confusion) → Immediate synchronized cardioversion (AF/AFL: begin at 200 J biphasic)
    ✓
  2. Stable → rate control (or early rhythm control): β-blocker (metoprolol) OR CCB (diltiazem/verapamil) OR digoxin. Early rhythm control (within 12 months of diagnosis) reduces cardiovascular outcomes in selected patients (EAST-AFNET 4, Class 2a); catheter ablation is Class 1 first-line rhythm control in selected patients (younger, few comorbidities, HFrEF)
    ✓
  3. Anticoagulate by CHA₂DS₂-VASc: men ≥1 / women ≥2 → consider; men ≥2 / women ≥3 → DOAC (apixaban/rivaroxaban/dabigatran) preferred over warfarin. Aspirin NOT recommended for stroke prevention

ICU / RESUS▸

SVT: narrow, regular, fast. VT: wide. WPW: delta wave, short PR

ABCDE

Assess stability; unstable → synchronised DCCV (pulseless VT → defibrillate); correct electrolytes.

Calculators:

  4. VT unstable / hypotension → synchronized cardioversion (narrow-complex 100 J; monomorphic VT 100 J; AF/AFL 200 J; polymorphic VT → unsynchronized defibrillation dose); pulseless → defibrillate

  • Delay transcutaneous pacing while escalating drugs in unstable bradycardia — drugs are a bridge only
Key
  • Atropine blocks ACh at SA/AV node → ↑ rate; often fails in infranodal block → pace.
  • Atropine ineffective → dopamine infusion 5–20 mcg/kg/min or epinephrine infusion 2–10 mcg/min are equal second-line alternatives to pacing (2025 AHA); temporary transvenous pacing reasonable (Class 2a) for persistent unstable bradycardia.
