Graz Critical Limb Ischemia Score in a Patient with Peripheral Arterial Disease

Description

Gary et al reported the Graz Critical Limb Ischemia Score for evaluating a patient with peripheral arterial disease. This can help to identify a patient at high risk for critical limb ischemia. The authors are from Medical University Graz in Austria.

Patient selection: peripheral arterial occlusive disease

Outcome: critical limb ischemia (CLI)

Parameters:

(1) age in years

(2) type 2 diabetes

(3) history of myocardial infarction

(4) therapy with low molecular weight heparin (LMWH)

(5) therapy with cardiac glycosides

(6) therapy with loop diuretics

(7) therapy with statin

Parameter	Finding	Points
age in years	< 65 years	0
	65 to 74 years	1
	>= 75 years	2
type 2 diabetes	absent	0
	present	2
history of myocardial infarction	no	0
	yes	2
therapy with LMWH	no	0
	yes	2
therapy with cardiac glycosides	no	0
	yes	1
therapy with loop diuretics	no	0
	yes	1
therapy with statins	no	0
	yes	-1

total score =

= SUM(points for all 7 parameters)

Interpretation:

• minimum score: -1

• maximum score: 10

• The higher the score the greater the risk of critical limb ischemia.

Total Score	Percent CLI
-1 or 0	8-9%
1	19%
2	30%
3	35%
4 to 7	44-54%
8	25% (1 patient)
9 or 10	100% (1 patient each)
