Heart Failure32% · 3.2x ROI
Arrhythmias48% · 2.1x ROI
Valvular Disease78% · 0.4x ROI

Studying valvular now gives 8x less score gain than heart failure.

“ACEi cough is rare and usually resolves”

Step 1

“ACEi cough → switch to ARB” classic Q

Professor downplays this. NBME loves it. Study the switch.
