Q

What are splinter hemorrhage and digital infarcts?
Causes of splinter haemorrhages?

A

Occlusion of small vessels/capillaries (dermal papillary vessels) resulting in longitudinal hemorrhage under the nails

Causes: TICS
- Trauma (most common)
- Infective endocarditis (15%)
- Connective tissue diseases (SLE)
- Systemic vasculitis (polyarteritis nodosa)

Q

What is collapsing pulse?
Causes of collapsing pulse?

A

Pulse with fast upstroke and fast downstroke on raising of arm
- Volume overload -> high stroke volume and bounding pulse
- Diastole -> arterial pressure fall significantly causing pulse to collapse -> widened pulse pressure

Causes:
- Aortic regurgitation (classic)
- AV fistula
- PDA
- Hyperdynamic circulation: anaemia, thyrotoxicosis, CO2 retention, fever

Q

Description of JVP

A

A C X V Y

A wave: atrial systole, peaks with S1

C point: ventricular contraction, coincides with tricuspid closure
(usually not visible)

X descent: atrial relaxation, ventricular systole

V wave: passive filling of right atrium while tricuspid valve closed. Peaks after S2

Y descent: decrease right atrial pressure deu to opening of tricuspid valve

Q

Causes of Elevated JVP

A
  • Right heart failure
  • Volume overload
  • Tricuspid stenosis or regurgitation
  • Pericardial effusion or constrictive pericarditis
  • SVC obstruction

Q

Causes of prominent A wave

A

Increased resistance to atrial emptying (during right ventricular systole)
- RV diastolic dysfunction (reduced RV compliance)
- Tricuspid stenosis
- Pulmonary hypertension
- Right ventricular outflow tract obstruction
> PS (Pulmonary stenosis)
> HOCM

Cannon A wave: RA contracts against closed TV (presystolic event)
Rises more rapidly, flickering motion
- Complete heart block
- Paroxysmal SVT or junctional tachycardia

16
Q

What is the murmur of mitral regurgitation?

A

Pansystolic
Loudest at apex
Radiates to axilla

17
Q

What is the murmur of mitral stenosis?

A

Low pitch, rumbling diastolic murmur

Loudest at the apex, best heard with the patient in the left lateral position with their breath held in expiration

18
Q

What murmurs might you hear in mixed aortic valve disease?

A

Ejection systolic murmur
Early diastolic murmur
Austin Flint murmur - rergurgitant jet passing through the aortic valve and hitting the adjacent mitral valve leaflet

19
Q

What are the causes of secondary hypertension?

A

Renal : renal parenchymal disease, revovascular disease, CKD

Endocrine: Cushing’s, hyperaldosteronism, adrenal hyperplasia, phaeochromocytoma, acromegaly, thyroid disease

Drug induced : NSAIDs, decongestants, oral contraceptives, corticosteroids, ciclosporin, anabolic steroids, illicit drug use

OSA
Coarctation of the aorta

20
Q

Which patients with hypertension should receive treatment?

A

10 year cardiovascular risk score >20%

Persistent BP of >160/100

All patients with co-existing diabetes or cardiovascular disease

21
Q

What are the causes of unilateral diminished or absent radial pulse?
(M: STARE)

A
  1. Shunt (Blalock-Taussig) - right/left thoracotomy scar corresponding to side of diminished pulse
  2. Takayasu arteritis
  3. Atherosclerosis - a/w diabetes mellitus
  4. Rib (cervical) - palpate anterior to trapezius muscle
  5. Embolism (AF)
22
Q

Describe this heart murmur

A

Ejection systolic murmur - AS

Crescendo-decrescdo murmur after S1, peaks in mid to late sustole and ends before S2

23
Q

What is the underlying pathology of malar flush?

A

Development of severe pulmonary hypertension leading to low output cardiac state
