MUSIC Risk Score of Vazquez et al for Mortality in a Patient with Heart Failure: Score for Sudden Death

Description

Vazquez et al reported the MUSIC scores for predicting mortality in an ambulatory patient with heart failure. One score predicts the risk of sudden death. The authors are from Valme University Hospital, University Hospital Sant Pau, University Hospital Arrixaca, and University Hospital Santiago de Compostela in Spain.

Patient selection: ambulatory patient with heart failure

Parameters:

(1) prior atherosclerotic vascular event (AVE): myocardial infarction, stroke, lower limb ischemia

(2) left atrial size indexed for BSA in mm per square meter

(3) left bundle branch block (LBBB) or intraventricular conduction delay (IVCD)

(4) non-sustained ventricular tachycardia (NSVT) and frequent ventricular premature beats

(5) serum NT-proBNP in ng/L

Parameter	Finding	Points for Sudden Death
prior AVE	no	0
	yes	8
left atrial size	<= 26	0
	> 26	11
LBBB or IVCD	no	0
	yes	7
NSVT	no	0
	yes	7
NT-proBNP	<= 1,000 ng/L	0
	> 1,000 ng/L	7

score for sudden death =

= SUM(points for sudden death)

Interpretation:

• minimum score: 0

• maximum score: 40

• A score > 20 is associated with high risk.

• Sudden death occurred in 20-22% in the high-risk group and 5% in the low-risk group.

Performance:

• The area under the ROC curve is 0.74..
