Q

65 y/o female to A&E , shortness of breath, sharp pain in RHS of chest, painful on taking a deep breath. Patient also complains of mild pain in RHS leg.

A

most likely to be PULMONARY FUCKING EMBOLISM

  1. pleuritic chest pain
  2. cough

looks in pain but no pallor, heart rate 95, respect rate 20, tempt okay. 155/95mmHg BP

Q

rib notching is a late feature of what…

A
  • coarctation of the aorta
17
Q

13 y/o recurrent attacks of collapse. episodes typicaly occur without warning or post sport.

on examination she has an ejection systolic murmur.

most likely cause

A

Hypertrophic obstructive cardiomyopathy

  • more common cause of murmur and recurrent collapse than aortic stenosis
  • myocardium becomes thickened, leading to cardiac muscle impairment and sudden death
  • autosomal dominant
18
Q

aortic dissection

A
  • tear in intimal layer of aorta
  • tearing chest pain
  • radiates to between the scapulae
  • hypertension great risk factor
19
Q

55 y/o female, shortness of breath on exertion and orthopnoea.

ECHO shows dilation in all four chambers. no regional wall motion.

left ventricular ejection fraction is poor.

indicative of…

A

DILATED CARDIOMYOPATHY

  • four chamber dilation
  • systolic dysfunction

chronic alcohol use may cause this

20
Q

Hypertrophic obstructive cardiomyopathy associated with what on ECG

A
  • deep ST depression and T-wave inversions
21
Q 
62 y/o male chest pain, severe shortness of breath. 
orthopnoea
paroxysmal noctural dyspnoea 
hepatomegaly 
smoker, COPD

indicative of what:

A

Right sided heart failure: COR PULMONALE

  1. raised JVP
  2. ankle oedema
  3. hepatomegaly
22
Q

pulmonary hypertension associated with what sound

A
  • loud second heart sound
23
Q

continuous ‘machinery’ like murmur associated with …

A
  • patent ductus arteriosus
24
Q

aortic regurgitation causes an early

A
  • early diastolic murmur
25
Q

34 y/o to A&E, fever, chills and felling unwell.

examination reveals vesicular breath sounds.

s1, s2 sounds with murmur.

indicative of ….

A

infective endocarditis

26
Q

42 y/o overweight man, two day history of anterior chest pain.

worse on deep inspiration and lying down.

A

Pericarditis

27
Q

young male smoker with symptoms similar to limb ishcaemia

  • cold peripheries
  • RHS foot ulcer
  • absent dorsalis pedis, posterior tibial, radial and ulnar pulses

THINK?

A

Buerger’s disease

28
Q

12 y/o girl, from bulgaria, 2 weeks unwell. joint pain intermittently in knees, hips and ankles.

on examination there are some pink, ring shaped lesions on trunk.

occasional jerking movements of face and hands.

indicative of:

A

Rheumatic fever

  • strep. pyogenes
  • antigen presentation to T cells
  • damage to smooth muscle of arteries
  • Aschoff bodies (granulomatous nodules) found in rheumatic heart fever
