Cardio Flashcards
CI and monitoring for ACEi
Contra:
preg/breastfeeding
renovascular disease - bilat renal artery stenosis
AS
Check U&Es before dose - acceptable changes = inc creatinine 30% and K to 5.5
SEs - angioedema, cough, hyperkal
ecg territories
Ant = V1-4 (LAD)
Inf = II, III, aVF (RCon)
Lat = I, V5-6 (Lcirc)
Tx for STEMI
MONA (O2 only if sats <94)
If PCI is possible within 120 mins - give prasugrel (or clopi if on DOAC)
preferable via radial access
If not - Fibrinolysis within 12 hours of onset of symptoms - given antithrombin and ticagrelor after
ecg after 90-120 mins - if persistent myocardial ischaemia still the consider PCI
GRACE risk assessment for NSTEMI
age
heart rate, blood pressure
cardiac (Killip class) and renal function (serum creatinine)
cardiac arrest on presentation
ECG findings
troponin levels
- If GRACE >3% risk of future adverse events - PCI
Tx for NSTEMI
Aspirin + Fondaparinux (if no immediate PCI is planned)
GRACE score
Low risk (<3^%) - conservative management - give ticagralor
High risk - PCI (immediately if unstable, otherwise within 72hrs)
Give prasugrel or ticagralor, unfractionated heparin
Mx for pericarditis
Tx - NSAID and colchicine
All patients should have transthoracic echocardiography
Adenosine SEs
Adenoside used to terminate SVTs
NB avoid in asthmatics due to risk fo bronchospasm
SEs - chest pain, bronchospasm, transient flushing
ACS summary
Shockable = VF/VT
Unshoickable = PEA, asystole
1mg adrenaline IV ASAP for non-shockable
Adrenaline after 3rd shock in VF/VT
Repeat every 3-5mins
VF/VT - amiodarone 300mg after 3 shocks
further 150mg after 5th shock
Antiplatelets in ACS (medicaly treated)
1 = Aspirin (life) + ticagrelor (12mo)
is aspirin CI - clopi (lifelong)
Antiplatelets in PCI
1 = Aspirin (life) + ticagrelor or prasurgrel (12mo)
is aspirin CI - clopi (lifelong)
Prasugrel CI if Hx pf stroke/TIA
Antiplatelets in TIA or ischaemic stroke
1 = Clopi (lifelong)
2= aspirin (lifelong) and dipyridamole (life)
Antiplatelets in PAD
1 = lifelong Clopi
2= lifelong aspirin
Management of aortic disection
Type A (Ascending aota) - surgical Mx, control BP pre-op
Type B (descending) conservative, bed rest, BP control
Features of aortic regurg
EarlyDM, collapsing pulse, wide pulse pressure, nailbed pulsation, head bobing
NB - acute presentation of AR - ?> inf endocarditis, ? aortic dissection
Features of AS
Pc - chest pain, SOB, syncope/presyncope
ESM, rad to corotids, narrow pulse pressure, slow rising pulse, soft/absent S2
Causes of AS
degen calcification - most common in >65
bicuspid aortic valve - most common in < 65
CHADSVASC score (SAD CHAVS)
S (prior stroke/TIA ) = 2
Age > 75 = 2
Diabetes
Congestive heart failure
HTN
Age 65-74
Vasc disease
Sex (female)
Anticoag in AF
Chadsvasc -
Score 1 - if men, consider
Score >2 - offer
DOAC = 1st line
If DOAC not tolerated - warfarin
AF - cardioversion
If < 48hrs since AF started - cardiovert
- DC cardioversion
- medical - amiodarone or flecainide (flecainide CI if structural Heart disease)
If unknown or > 48hrs
Give anticoag for 3w then cardiovert (electrical better)
AF and stroke
If AF and TIA - start anticoag as soon as the haemorrhage excluded
If stroke - anticoag after 2w
ecg; PR > 0.2s
1st deg heart block
ecg - second deg heart block
Mobitz 1 (wenchebach) - progressive prolongation then drop
Mobitz 2 - PR constant but sometimes dropped beat
Causes of artificially low BNP
ACEi, ARB, diuretics
Side effects of BBs
Bronchospasm, cold peripheries, fatigue, sleep disturbances, erectile dysfunc
