coronary artery supplies

the AV node?

Right

Bleeding on dabigatran?

Idarucizumab can
reverse

First line investigation
for stable chest pain of

suspected coronary
artery disease
aetiology?

Contrast-enhanced CT
coronary angiogram

Drug eluting stent - what
is of paramount
importance for 12
months?

DAPT

Delay routine surgery
etc

Aminophylline effect on
adenosine?

Which drug should be

and B blockers don't go

together)

How can you determine

Nielsen syndrome and

Romano-Ward
syndrome?

Both long QT

JLN - deafness (K+
channel problem)
RW - no deafness

HTN not controlled on
just an ACE inhibitor?

Add CCB or a thiazide
LIKE diuretic eg

Indapamide (preferable
to an actual Thiazide)

Treatment for heart
failure with LV failure?

ACE inhibitor and B
blocker, reduces after

load

DVLA advice for the
heart?

CABG 4 weeks
MI 4 weeks unless successfully

treated by angioplasty then 1
week

Elective angiogram 1 week
ICD: 6 months if for VT
1 month if prophylactic

Heavy goods never again
PPM 4 weeks

Pansystolic murmur
worse on inspiration?
When do you see this
valvular abnormality?

Tricuspid regurgitation

Happens in Ebsteins
anomaly (+WPW)

Takayasu arteritis

Granulomatous (giant cell)
inflammation of media and
adventitia of large elastic

arteries.
Most often affects thoracic

aorta and its proximal
branches and pulmonary

arteries.

If > 55 how useful is the
PERC score?

No - cant use after 55 yrs
of age

All patients post MI?

dual antiplatelet therapy
(aspirin plus a second

antiplatelet agent)
ACE inhibitor
beta-blocker
statin

Chest pain post initial MI
- which blood test?

CK-MB is useful to look
for reinfarction as it

returns to normal after 2-
3 days

(troponin T remains
elevated for up to 10

days)

ticagrelor/dypridamine

cause dyspnoea

due to the impaired
clearance of adenosine

(adenosine shouldn't be
given in asthmatics)

binding protein C

endocarditis after dental

work?

Streptococcus mitis and
Streptococcus
sanguinis.

MOA of dipyridamole

Non-specific
phosphodiesterase
inhibitor and decreases
cellular uptake of

adenosine
Inhibits platelet

aggregation
