CCS Atrial Fibrillation 2020 Flashcards
Who has more Afib men or women?
Male (1.5x)
What are 7 triggers for Afib from every day life/substances ?
- stimulants
- ETOH
- Sleep deprivation
- Emotional stress
- Physical exertion
- Sleep
- Digestive
What are the 5 CCSAF scores?
0: No symptoms
1: Minimal symptoms
2: Minor effect/Mild awareness
3: Moderate effect, aware on most days
4: Severe impact
What is recommendation for screening?
‘Opportunistic screening’ > 65 -> meaning trying to detect AF during medical encounters
In patients with AF what is BP ETOH and OSA recommendation?
ETOH 1 or less drink per day
OSA (AHI > 15/hour) -> CPAP
130/80mmhg at rest and <200/100mmhg
Which two patients population to use VKA instead of DOAC?
- Mechanical valve
- Moderate to severe MS
Screening renal function for patients on OAC?
Baseline and then annually
What does CCS recommend for DOAC when CrCl 15-30?
Follow normal algorithm (No RCT data though)
How advanced does Liver disease need to be to not use DOAC?
Severe, CP score C
How to manage OAC around catheter ablation?
Uninterrupted OAC
How to manage OAC after 2 months post ablation if successful?
No change -> as per CCS algorithm
What 4 populations on AF to bridge?
- Mechanical valves
- Moderate-severe MS
- CHADS 5-6
- Recent Stroke/TIA
Approach to peri-op with VKA if no bridge?
Hold 5 days before, measure INR 1 day before. Proceed if INR < 1.5
Approach to peri-op with VKA if bridge planned?
Hold 5 days before, LMWH 3 days before , then LMWH post until therapeutic
When to hold DOACs pre op? (Exclude Dabigatran)
-1 day before if low/moderate bleeding risk, 2 days before if high bleeding risk
When to hold Dabigatran pre op if CrCl < 50?
- Last dose 3 days before if low/mod risk
- Last dose 5 days before if high risk
What is Andexanet Alfa reversal agent for?
- Apixaban
- Edoxaban
- Rivaroxaban
When to start OAC in acute ischemic stroke with New AF based on severity?
- Mild Stroke (NIHSS < 8) : 3 days
- Moderate Stroke (NIHSS 8-15) : 6 days
- Large Stroke (NIHSS > 16) : 12 days
