Q

What type of ca channel blocker do you use for anti angina?

A
Dihydropyridine!
Amlodipine
Felodipine
Nifedipine SR (NOT fast as increase mortality)
Not neg inotropic 

Dont use nifedipine in severe AS, HOCM, HF

Q

Action of dihydropyridine vs non dihydropyridine Ca ch blockers?

A

Dihydropyr- systemic AND CORONARY vasodilator. Not neg inotropic

Non-dihyro- arteriolar vasodilation
centrally acting to reduce HR, BP, contractility, prolong diastole. Neg inotropes

Q

How does nicorandil work?

A

Arterial and venous vasodilator- systemic and coronary. Acts by stimulating cGMP formation to eventually reduce sensitivity of smooth muscle to calcium

Can use with calcium channel blockers in angina if nitrate intolerant. also reduces CV events!
Flushing and palpitations

Q

Is CTCA a viable alternative to exercise testing in people with chest pain?

A

Yes, non inferior in terms of outcomes

Also reduces number of people who go on to have a normal angiogram

Q

Who would you treat out of moderate risk CV category?

A

Maouri, south asian, middle eastern
FH CVD premature
BP over 160

Start a statin and BP lowering therapy

Q

Cilostazol in PVD- how work?

A

Phosphodiesterase 3 inhibitor
Can cause rebound tachy and cannot give in CCF
Have to stop pre-op

In au for rest pain or evidence of necrosis

Q

When do you start spiron post MI?

A

MUST be within 14 days

on PBS if LVEF under 40% within 3-14 days post MI

16
Q

How does spiro give you breasts?

A

Increases testosterone to oestradiol production
Decreases testosterone production in testes
Displace testosterone from SHBG and so increase clearance

17
Q

How does hydralazine work?

A

Selective arterial vasodilator–>reduce afterload

18
Q

How does ISMN work?

A

Converted to NO in cells–>increase cGMP–> veno and vasodilation–>reduce preload and afterload.

19
Q

Is diltiazem dihydro or non dihydro

A

In between in selectivity

Reduce BP without inducing reflex tachy

20
Q

What E-Eprime is normal?

A

Less than 8

21
Q

What do alpha 1 receptors do?

A
all post synaptic
smooth muscle vasoconstriction
skin vasoconstriction
abdominal viscera vasoconstricition
GU/GI sphincter constriction
mydriasis

NORAD more

22
Q

alpha 2 do what?

A

mixed effects smooth muscle
increase amylase
increase AV node conduction- dromotropic
glycogenolysis, inhibit insulin release

ADRENALINE more

23
Q

Beta 1 receptors do what?

A
inotrope
chronotrope
increase amylase
dromotropic 
glycogenolysis

ISOPREN more than ADREN

24
Q

Beta2 receptors do what?

A
ISOPREN more than ADREN
SM relaxation
vasodilation skeletal muscle
hypokalaemia
uterine relaxation
25
Q

When to repair a thoracic aortic aneurysm?

A

Over 4cm if trying to get preg and marfans
Marfans over 5
Any one else over 5.5

26
Q

In degenerative aortic disease, is there evidence that modifying RF reduces rate of expansion?

A

No evidence

27
Q

When to repair a triple A?

A

Over 5.5cm or grows half a cm in a year
NO benefit beta blockers, no data for ACE or statin
Use of macrolide may slow expansion in patients with serological evidence of chlamydia pneumoniae

28
Q

Most common heart thing in turners?

A

Bicuspid valve

Then coarctation

29
Q

time line of instent thrombosis and restenosis?

A

Thrombosis usually first month- present as MI
In stent restenosis usually first 3-6 months, present as angina, more likely if renal disease, stent in a venous graft, diabetes

In stent thrombosis 1-2%
Restenosis 5-20%

30
Q

High mortality post MI correlates with…

A

Killip class which is basically increasing severity of cardiac failure

31
Q

Sustained VT

A

stable- amiodarone or sotalol or lignocaine

or if no LV dysfunction could use flecanide

32
Q

Torsades mx

A

if underlying brady- atropine

TTV pacing or mag sulphate or isoprenaline or lignocaine

AVOID AMIODARONE, SOTALOL, DISOPYRAMIDE, FLECANIDE

33
Q

NSVT

A

atenolol or metoprolol or amiodarone or flecanide or sotalol

34
Q

What things lower BNP and upper BNP?

A

Basically all antihypertensives (not ca ch bl)
and obesity

LVH, tachy, RV overload, Hypoxaemia, PE, GFR under 60, age over 70, cirrhosis, COPD, diabetes
