Table 1. Description of INTERMACS PROFILES.

Severity of advanced heart failure in patients being considered for mechanical circulatory support has been characterized as per the INTERMACS^* profiles.

PROFILE	Description
1	Critical cardiogenic shock
	- life threatening hypotension and rapidly escalating inotropic pressor support
2	Progressive decline
	- dependent on inotropic support, with signs of deterioration
3	Stable but inotrope dependent
	- clinically stable on mild-moderate doses of intravenous inotropes
4	Resting symptoms
	- at home on oral therapy, but frequently has symptoms of congestion
5	Exertion intolerant
	- comfortable at rest but unable to engage in any activity
6	Exertion limited
	- comfortable at rest without evidence of fluid overload, able to do mild activity
7	Advanced NYHA Class 3
	- clinically stable with a reasonable level of comfortable activity
