Cardiothoracic and vascular
la-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS surgery covers an unusually wide anatomical territory, from the heart and great vessels through the lungs and mediastinum to the peripheral arterial and venous systems, and each region produces its own recognisable pattern of symptoms and signs. The aim of this Series is to equip you with the ability to enumerate and interpret the symptoms and signs of common lesions across this specialty, covering the general approach to cardiothoracic and vascular assessment, common cardiac lesions, common thoracic lesions, and common vascular lesions. Building this recognition skill early gives you the foundation needed for everything that follows in this course, from chest trauma through to definitive surgical management. This Series opens with the general approach to cardiothoracic and vascular symptoms, moves through common cardiac lesions and common thoracic lesions, and closes with common vascular lesions, building a comprehensive picture of symptom and sign recognition across the whole specialty. Series Learning Outcomes At the end of this Series, you should be able to: • SLO 1.1: describe the principles of history taking and examination in cardiothoracic and vascular surgery • SLO 1.2: interpret common cardiac symptoms and respiratory symptoms • SLO 1.3: describe the symptoms and signs of valvular and ischaemic heart disease • SLO 1.4: describe the symptoms and signs of pericardial disease • SLO 1.5: describe the symptoms and signs of common thoracic lesions, including lung and mediastinal masses • SLO 1.6: interpret the symptoms and signs of pleural disease • SLO 1.7: describe the symptoms and signs of arterial and aneurysmal disease • SLO 1.8: describe the symptoms and signs of venous disease
la-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS 1.1 Approach to Cardiothoracic and Vascular Symptoms 1.1.1 principles of cardiothoracic and vascular history and examination A wide territory demanding a structured approach A thorough cardiothoracic and vascular history covers the character, onset, and triggers of chest pain, breathlessness and its relationship to exertion, palpitations, cough and haemoptysis, and limb symptoms such as claudication or swelling, alongside relevant risk factors including smoking, hypertension, diabetes, hyperlipidaemia, and family history of cardiovascular disease, since these risk factors shape the probability of one diagnosis over another before examination even begins. Examination follows a structured sequence: general inspection for cyanosis, clubbing, or peripheral oedema, examination of the pulse and jugular venous pressure, palpation and auscultation of the praecordium, examination of the chest for respiratory signs, and, where relevant, examination of the peripheral pulses and limbs for vascular signs, a comprehensive approach that reflects the genuinely wide anatomical territory this specialty covers compared with many others. Fill in the blank: Risk factors such as smoking and hypertension shape the ________ of one diagnosis over another before examination begins. 1.1.2 interpreting cardiac symptoms What the heart tells the patient, and what the patient tells you Chest pain of cardiac origin classically presents as a central, crushing or tight sensation, often radiating to the jaw, neck, or left arm, and precipitated or worsened by exertion and relieved by rest, though atypical presentations, particularly in women, older adults, and diabetic patients, are common enough that a normal or unusual pain character should never be used alone to exclude a cardiac cause. Palpitations, an unpleasant awareness of the heartbeat, and syncope, transient loss of consciousness, both warrant careful characterisation, since palpitations occurring with exertion or associated with syncope carry considerably greater diagnostic weight than brief, isolated palpitations at rest, and syncope during exertion in particular should always raise concern for a significant underlying structural or rhythm abnormality requiring prompt further evaluation. Fill in the blank: Syncope occurring during exertion should always raise concern for a significant underlying structural or ________ abnormality.

Cough and haemoptysis, coughing up blood, each carry distinct diagnostic significance, with haemoptysis in particular warranting careful further evaluation regardless of volume, since even small-volume haemoptysis can herald a serious underlying thoracic pathology, and chest pain that varies with respiration or position, referred to as pleuritic chest pain, points towards a pleural or musculoskeletal cause rather than a cardiac one. Fill in the blank: Chest pain that varies with respiration or position is referred to as ________ chest pain.

The corresponding sign, a murmur, is characterised by its timing in the cardiac cycle, location where it is best heard, radiation, and character, with aortic stenosis producing an ejection systolic murmur radiating to the carotids, and mitral regurgitation producing a pansystolic murmur radiating to the axilla, distinguishing features that, together with the associated symptoms, allow a confident clinical diagnosis to be reached before any imaging is performed. Fill in the blank: Aortic stenosis classically produces an ejection systolic murmur radiating to the ________. 1.2.2 ischaemic heart disease: symptoms and signs From stable angina to the acute coronary syndrome Ischaemic heart disease ranges from stable angina, predictable exertional chest pain relieved by rest, to acute coronary syndrome, encompassing unstable angina and myocardial infarction, presenting with more severe, often unprovoked chest pain that may be accompanied by breathlessness, sweating, nausea, and a sense of impending doom, a symptom cluster that should always be treated as a genuine emergency until proven otherwise. Physical examination in ischaemic heart disease can be entirely normal between episodes, or reveal signs of an associated complication, such as a new murmur suggesting acute mitral regurgitation from papillary muscle dysfunction, or signs of heart failure following significant myocardial damage, underlining why a normal examination alone should never be used to exclude a significant ischaemic event when the history is otherwise suggestive. Fill in the blank: Acute coronary syndrome encompasses unstable angina and myocardial ________.
