Echocardiography-Based Risk Score of Zhu et al for a Patient on Hemodialysis

Description

Zhu et al reported a model for predicting overall survival for a patient receiving hemodialysis. This is based on echocardiographic and clinical findings. The authors are from the Second Affiliated Hospital of Soochow University in Suzhou, China.

Patient selection: hemodialysis

Outcome: 3-year survival

Parameters:

(1) age in years

(2) hypertension

(3) diabetes mellitus

(4) hemoglobin in g/L

(5) left atrial diameter index (LADI, left atrial diameter divided by body surface area) in mm per square meter

(6) cardiac valve calcifications (CVC) - none, valve sclerosis, valve calcifications

(7) cardiac valve regurgitation (CVR)

points for LADI =

= (3.3333 * (LADI)) - 50

Parameter	Finding	Points
age in years	<= 65 years	0
	> 65 years	26.3
hypertension	no	0
	yes	42.9
diabetes mellitus	no	0
	yes	27.2
hemoglobin	< 90 g/L	11.3
	>= 90 g/L	0
valve calcifications	none	0
	valve sclerosis	29.7
	valve calcifications	60.2
valve regurgitation	no	0
	yes	31.6

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 299.5

Score	3-Year Overal Survival
< 70	> 95%
70 to 246	X = (-0.0000008769 * ((score)^3)) + (0.0003176 * ((score)^2)) - (0.06136 * (score)) + 5.983 probability = 1 / (1 + EXP((-1) * X))
> 246	< 5%
