Cardiovascular symptoms

Chest pain

Serious causes

  • MI
  • Dissecting aortic aneurysm
  • Pericarditis
  • Pulmonary embolism

Description

  • Character
    • Constricting (angina, oesophageal spasm, anxiety)
    • Sharp (pleura, pericardium)
    • Prolonged dull central chest pain (MI)
  • Radiation
    • Shoulder/both arms or epigastric (cardiac ischaemia)
    • Instantaneous, tearing, interscapular or retrosternal (aortic dissection)
  • Precipitants
    • Cold, exercise, palpitations or emotion (cardiac or anxiety)
    • Food, lying flat, hot drinks, alcohol (oesophageal spasm but may still be cardiac)
  • Relieving factors
    • Rest of GTN (cardiac)
    • Antacid (GI)
    • Leaning forward (pericarditis)
  • Associations
    • Dyspnoea (cardiac pain, pulmonary emboli, pleurisy, or anxiety)
    • Nausea, vomiting, or sweating (MI)
    • Chest pain with tenderness (Tietze's syndrome)
  • Pleuritic pain
    • Pain exacerbated by inspiration 
    • Inflammation of pleura
    • Differentials include musculoskeletal (fractured rib) or subdiaphragmatic pathology (gallstones)
  • Acutely ill patients
    • Admit to hospital
    • Check pulse and BP in both arms
    • JVP
    • heart sounds
    • Examine legs for DVT
    • Give O2 by mask
    • IV line
    • Relieve pain (morphine 5-10mg IV slowly 2mg/min + antiemetic)
    • Cardiac monitor
    • 12 lead ECG
    • ABG
    • Think about: dissection, zoster, ruptured oesophagus, cardiac tamponade with shock, opiate addiction



Dyspnoea

  • Causes
    • LVF
    • Pulmonary embolism
    • Any respiratory cause
    • Anxiety
  • History
    • SOB at rest or exertion
    • Exercise tolerance
    • Episodic or triggered by lying flat
    • Heart failure: orthopnoea (pillows at night), paroxysmal noctural dyspnoea (waking up at night gasping for breath), and peripheral oedema
    • Pulmonary embolism: acute onset of dyspnoea and pleuritic chest pain, risk factors for DVT



Palpitations

  • Causes
    • Ectopics
    • AF
    • SVT
    • Ventricular tachycardia
    • Thyrotoxicosis
    • Anxiety
    • Phaeochromocytoma
  • History
    • Previous episodes
    • Precipitating/relieving factors
    • Duration of symptoms
    • Chest pain
    • Dyspnoea
    • Dizziness
    • Patient's pulse?



Syncope

  • Cardiac or CNS events
  • Vasovagal 'faints' are common (pulse decreased, pupils dilated)
  • Cardiac cause: Chest pain, palpitations, dyspnoea
  • CNS cause: Aura, headache, dysarthria, limb weakness
  • Ask observer:
    • Was there pulse?
    • Limb jerking?
    • Tongue biting?
    • Urinary incontinence?
    • Rapid (arrhythmia)?
    • Prolonged (seizure)?
