Right Heart Score of Haddad et al for a Patient with Pulmonary Arterial Hypertension (PAH)

Description

Haddad et al developed a right heart score for evaluating a patient with pulmonary arterial hypertension (PAH). This correlates with long-term outcome. The authors are from Stanford University, VU University Amsterdam, Montreal University, and Universite Paris-Sud.

Patient selection: idiopathic, familial, drug-associated, toxin-associated PAH

Outcome: survival

Parameters:

(1) right ventricular function (based on American Society of Echocardiography criteria)

(2) right atrial enlargement

(3) systolic blood pressure in mm Hg

Parameter	Finding	Points
right ventricular function	normal	0
	mild dysfunction	1
	moderate or severe dysfunction	2
right atrial enlargement	none to moderate	0
	severe	1
systolic blood pressure	< 110 mm Hg	1
	>= 110 mm Hg	0

total score =

= SUM(points for all 3 parameters) + 1

Interpretation:

• minimum score: 1

• maximum score: 5

• The higher the score the worse the survival.

Score	5-Year Survival
1	100%
2	96%
3	68%
4	44%
5	15%

Performance:

• The area under the ROC curve was 0.88.
