Cardiovascular Examination

Updated: Apr 30, 2019

Introduction

  • Wash hands

  • Introduce yourself

  • Confirm patient details – name / DOB

  • Explain the examination

  • Gain consent

  • Position the patient at 45° with their chest exposed

  • Chaperone??


Ask if the patient currently has any pain


 

General inspection


  • Bedside – treatments or adjuncts? – GTN spray / O2 / medication / mobility aids

  • Obesity/Cachexia

  • Check the patient is comfortable at rest

  • Malar flush – plum red discolouration of cheeks – may suggest mitral stenosis

  • Inspect chest - scars or visible pulsations? (remember to look underneath arms for thoracotomy scars and for small scars from minimally invasive surgery)

  • Inspect legs - scars from saphenous vein harvest for CAGB / peripheral oedema / missing limbs or toes


 

Hands


Hands out with palms facing downwards

  • Splinter haemorrhages – reddish/brown streaks on the nail bed – bacterial endocarditis

  • Finger clubbing - infective endocarditis and cyanotic congenital heart disease

  • Koilonychia –Iron Deficiency Anaemia


Splinter haemorrhages

Hands out with palms facing upwards

  • Colour – dusky bluish discolouration (cyanosis) suggests hypoxia

  • Temperature – cool peripheries may suggest poor cardiac output/hypovolaemia

  • Sweaty/Clammy– can be associated with acute coronary syndrome

  • Janeway lesions – non-tender maculopapular erythematous palm pulp lesions – bacterial endocarditis

  • Osler’s nodes – tender red nodules on finger pulps/thenar eminence – infective endocarditis

  • Tar staining – smoker – risk factor for cardiovascular disease

  • Xanthomata – raised yellow lesions – often noted on tendons of the wrist – caused by hyperlipidaemia

  • Capillary refill time – normal is <2 seconds – if prolonged may suggest hypovolaemia


Osler node and Janeway lesion

 

Pulses

  • Radial pulse – assess rate and rhythm

  • Radio-radial delay: A delay may suggest aortic coarctation

  • Brachial pulse – assess volume and character, state of vessel wall (arteriosclerosis)

  • Collapsing pulse – associated with aortic regurgitation

  1. First, ensure the patient has no shoulder pain

  2. Palpate the radial pulse with your hand wrapped around the wrist

  3. Raise the arm above the head briskly

  4. Feel for a tapping impulse through the muscle bulk of the arm as blood empties from the arm very quickly in diastole, resulting in the palpable sensation

  5. This is a water hammer pulse and can occur in normal physiological states (fever/pregnancy), or in cardiac lesions (e.g. AR/PDA) or high output states (e.g. anaemia/AV fistula/thyrotoxicosis)


 

Blood pressure:

  • Measure blood pressure and note any abnormalities – e.g. hypertension/ hypotension

  • Narrow pulse pressure is associated with aortic stenosis

  • Wide pulse pressure is associated with aortic regurgitation


 

Carotid pulse:


  • Assess character and volume – e.g. slow rising character in aortic stenosis

  • It’s often advised to auscultate the carotid artery for a bruit before palpating, as theoretically palpation may dislodge a plaque which could lead to a stroke

  • However, if you perform carotid auscultation at this point, remember that the ‘bruit’ may actually be a radiating murmur!


 

Jugular venous pressure (JVP)

  • Raised JVP may indicate – fluid overload / right ventricular failure / tricuspid regurgitation


JVP waves with timing

 

Hepato-jugular reflux:

  • Apply pressure to the liver and observe the JVP for a rise

  • In healthy individuals, this should last no longer than 1-2 cardiac cycles (it should then fall)

  • If the rise in JVP is sustained and equal to or greater than 4cm this is a positive result

  • A positive hepatojugular reflux sign is suggestive of right-sided heart failure and/or tricuspid regurgitation


 

Face


  • Conjunctival pallor – anaemia– ask the patient to pull down on eyelids

  • Corneal arcus – yellowish/grey ring surrounding the iris – hypercholesterolaemia

  • Xanthelasma – yellow raised lesions around the eyes – hypercholesterolaemia

  • Malar flush - plum red discolouration of cheeks – may suggest mitral stenosis

  • Central cyanosis – bluish discolouration of the lips and/or the tongue

  • Angular stomatitis – inflammation of the corners of the mouth – iron deficiency

  • High arched palate – suggestive of Marfan syndrome– ↑ risk of aortic aneurysm/dissection

  • Dental hygiene – important if considering sources for infective endocarditis

  • Hydration


 

Inspection of the chest


  • Scars/Rashes – shingles causes chest pain

  • Chest wall deformities – pectus excavatum / pectus carinatum

  • Visible pulsations (forceful apex beat may be visible) – hypertension/ventricular hypertrophy


 

Palpation


Apex beat:

  • Lateral displacement suggests cardiomegaly

  • Impalpable: Obesity, emphysema, pericardial effusion


Heaves:

  • A parasternal heave is a hypertrophic ventricular wall thrusting against inside the chest wall

  • Parasternal heaves are present in patients with right ventricular hypertrophy

  • Place the heel of your hand parallel to the left sternal edge (fingers vertical) to palpate for heaves

Thrills:

  • A thrill is a palpable vibration caused by turbulent blood flow through a heart valve (the thrill is a palpable murmur)

  • You should assess for a thrill across each of the heart valves in turn


Heaves and Thrills

 

Auscultation

Auscultate the four valves


  • Palpate the carotid pulse to determine the first heart sound.

  • Auscultate all valve areas using the bell and diaphragm of the stethoscope:

Mitral valve – 5th intercostal space – midclavicular line (apex beat)

Tricuspid valve – 4th or 5th intercostal space – lower left sternal edge

Pulmonary valve – 2nd intercostal space – left sternal edge

Aortic valve – 2nd intercostal space – right sternal edge

  • Auscultate the carotid arteries with the patient holding their breath to check for radiation of an aortic stenosis murmur (this is known as an accentuation manoeuvre).

  • Sit the patient forwards and auscultate over the aortic area during expiration to listen for the murmur of aortic regurgitation (this is known as an accentuation manoeuvre).

  • Roll the patient onto their left side and listen over the mitral area with the bell during expiration for mitral murmurs (regurgitation/stenosis).


 

Conclusion


Auscultate lung bases:

  • Crackles may suggest pulmonary oedema (e.g. secondary to left ventricular failure)

  • Consider chronic lung diseases if the patient has no other signs of fluid overload (e.g. pulmonary fibrosis)


  • Sacral oedema/pedal oedema – may indicate right ventricular failure

  • Abdominal Palpitation, aortic bruits


  • Thank the patient

  • Wash hands

  • Summarise findings


 

Suggest further assessments and investigations

  • Record a 12-lead ECG – arrhythmias / myocardial ischaemia

  • Dipstick urine – proteinuria / haematuria – hypertension


 

Murmurs:

  • Caused by turbulent blood flow in the heart due to valve dysfunction or heart defects occurring at specific points of the cardiac cycle

Characteristics:

  • Site

  • Radiation

  • Characteristics

  • Timing

  • Effect of respiration

  • Effect of position


  • Right sided murmur (pulmonary/tricuspid) will increase during held inspiration

  • Left sided murmurs increase during held exhalation


Bruit

  • Audible (turbulent) blood flow in arteries associated with distortion of vessel walls


Auscultation sites for bruits

Peripheral Vascular Assessment

  • State of peripheral tissues: Colour (normal/pale), Temperature, Viability

  • Venous Circulation: Varicose veins, Ulcers

  • Leg Pulses: femoral, popliteal, tibialis posterior, dorsalis pedis
