ABC-VT Risk Score of Voskoboinik et al for Adverse Outcome in a Patient with Frequent Premature Ventricular Complexes

Description

Voskoboinik et al reported the ABC-VT risk score for predicting adverse outcomes in a patient with frequent premature ventricular complexes (PVCs). This can help to identify a patient who may require more aggressive management. The authors are from the University of California San Francisco, Kosin University and Samsung Medical Center in Seoul.

Patient selection: frequent (> 5%) premature ventricular complexes

Adverse outcome: decline in LVEF by 10%, heart failure hospitalization, or cardiovascular mortality.

Parameters:

(1) PVC axis (A)

(2) burden (B)

(3) PVC coupling interval in milliseconds (C)

(4) nonsustained ventricular tachycardia (VT)

Parameter	Finding	Points
axis	superior	1
	other	0
burden	< 10%	0
	10 to 20%	2
	> 20%	3
coupling interval	<= 500 ms	0
	> 500 ms	4
ventricular tachycardia	no	0
	yes	4

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 12

Total Score	Risk of Adverse Outcome
0 to 4	low
5 to 8	intermediate
9 to 12	high
