distributed continuous data
Linear Regression ✔️Ans - One continuous independent (exposure)
variable
2+ continuous dependent (outcome) variables
Simple Logistic Regression ✔️Ans - 2+ categorical or continuous
independent variables
One categorical dependent variable
Non-valvular AF ✔️Ans - AF in the absence of moderate or severe
mitral stenosis, mitral valve repair, or mechanical heart valves
CHADS2 vs CHADS2VASc ✔️Ans - CHADS2 = CHF, HTN, Age 75+, DM,
stroke (2)
CHADS2VASc = CHF, HTN, Age 75+ (2), DM, stroke (2), vascular disease, Age
65-74, female
OAC indicated for score 2+ in men and 3+ in women
When to cardiovert AF ✔️Ans - AF >48h, anticoagulate for at least 3
weeks before cardioversion and at least 4 weeks after cardioversion
regardless of CHADS2VASc score
May utilize a TEE to visualize the atria to skip the anticoagulation prior to
cardioversion
,HASBLED ✔️Ans - HTN (>160)

preventing production of clotting factors 2 (72h), 7 (6h), 9 (24h), 10 (36h)
