“For me, the only things of interest are those linked to the heart”(Audrey Hepburn)
Presenting Complaint • Chest pain • Shortness of breath • Ankle swelling • Palpitations • Syncope • Intermittent claudication
Character of pain Severity Duration Radiation At rest or on exertion Previous episodes Relieving factors Worse on taking a deep breath (pleuritic) Worse on movement Autonomic symptoms Sweating Nausea Chest Pain
Cardiovascular Angina Stable Unstable Myocardial infarction Aortic dissection Myocarditis Pleuropericardial Pericarditis Pleurisy Pneumothorax Gastrointestinal Gastro-oesophageal reflux Oesophageal spasm Chest wall Coughing Intercostal muscle strain/myositis Herpes zoster Viral pleurodynia Thoracic radiculopathy Rib fracture Rib tumour Costochondritis Causes of Chest Pain
Dyspnoea • Unexpected awareness of breathing • At rest or on exertion • Quantify exercise tolerance (yards walked, stairs climbed) • Orthopnoea = shortness of breath on lying supine • Number of pillows • Paroxysmal nocturnal dyspnoea
Airways disease COPD Chronic bronchitis Emphysema Asthma Bronchiectasis Cystic fibrosis Parenchymal disease Pneumonia Pulmonary fibrosis Tumour Pneumothorax Pulmonary vasculature Pulmonary embolism Pulmonary hypertension Chest wall Pleural effusion Rib fracture Kyphoscoliosis Neuromuscular Cardiac Left ventricular failure Mitral valve disease Cardiomyopathy Pericardial effusion Other Anaemia Acidosis Psychogenic Causes of Dyspnoea
Pulmonary Oedema Normal Chest Radiograph Pulmonary Oedema
Unilateral or bilateral Proximal extent of oedema Pitting/non-pitting Cardiac Congestive cardiac failure Right ventricular failure Cor pulmonale Constrictive pericarditis Drugs Calcium channel blockers Other Cirrhosis Nephrotic syndrome Protein-losing enteropathy Deep vein thrombosis Hypothyroidism Lymphoedema Ankle Swelling
= Unexpected awareness of heartbeat Ask patient to tap palpitations on chest Slow or fast Regular or irregular Duration Speed of onset or offset Relieving manoeuvres Sinus tachycardia Ventricular extrasystoles Atrial fibrillation Atrial flutter Supraventricular tachycardia Ventricular tachycardia Palpitations
Syncope • = Transient loss of consciousness due to cerebral hypoperfusion • What was the patient doing at the time? • Standing for prolonged period • Standing up suddenly (postural hypotension) • Coughing • Prodromal symptoms • Abnormal movements (epilepsy) • Sensation of room spinning (vertigo)
Intermittent Claudication • Pain in one or both calves, thighs or buttocks • Brought on by walking a certain distance (claudication distance) • Worse on walking uphill • Relieved by rest • Suggests peripheral vascular disease
Risk factors for Ischaemic Heart Disease • Hyperlipidaemia • Diabetes mellitus • Smoking • Hypertension • Obesity • Family history
Past Medical History • Rheumatic fever • Previous cardiac investigations • Previous myocardial infarction • Coronary angioplasty + stent insertion • Coronary artery bypass grafting • Pacemaker insertion
Medications • Anti-anginal agents • Use of sublingual nitrate spray • Antihypertensive agents • Anti-arrhythmics • Statins • Platelet inhibitors, e.g., Aspirin • Anticoagulants, e.g., Warfarin • Allergies • NB Document in front of chart and inform nurses
Social History • Occupation • e.g., train driver, long distance truck driver • Smoking • Number of pack years • Alcohol intake • Stairs at home
Family History • Ischaemic heart disease • Angina • MI • CABG • Hypertrophic obstructive cardiomyopathy • Dilated cardiomyopathy
