Cardiac Hand Examination Flashcards
1
Q
Cardiac hand examination sequence
A
- Feel the temperature of the hands and measure capillary refill time.
- Examine the hands for tobacco staining, skin crease pallor (anaemia) or peripheral cyanosis.
- Look at the nails for finger clubbing and for splinter haemorrhages: linear, reddish-brown marks along the axis of the fingernails and toenails.
- Examine the extensor surface of the hands for tendon xanthomata: hard, slightly yellowish masses over the extensor tendons of the hand from lipid deposits.
- Examine the palmar aspect of the hands for:
Janeway lesions: painless, blanching red macules on thethenar/hypothenar eminences - Osler’s nodes: painful raised erythematous lesions, typically on the pads of the fingers

Q
Cardiac- hands (CRT, other indicators of disease)
A
- The hands usually feel dry and warm at ambient temperature.
- Normal capillary refill time is 2 seconds or less.
- Cool extremities and prolonged capillary refill time signify impaired peripheral perfusion, which may occur in shock
- chronic conditions associated with a low cardiac output state (as in severe aortic stenosis, mitral stenosis or pulmonary hypertension).
- One or two isolated splinter haemorrhages from trauma are common in healthy individuals, especially in manual workers.
- Splinter haemorrhages are found in infective endocarditis and some vasculitic disorders.
- A petechial rash(caused by vasculitis), most often present on the legs and conjunctivae (see Fig. 4.5E), is a transient finding in endocarditis and can be confused with the rash of meningococcal disease.
- Janeway lesions and Osler’s nodes (see Fig. 4.5A and C) are features of endocarditis but are rare
- Tendon xanthomata are a sign of familial hyper-cholesterolaemia, a genetic disorder associated with severe elevations in serum (ChE) and premature CAD
