Intervention in end-stage heart failure.Is it ever too late ?

Can you solve my problem ?

results• The principal outcomes occurred in 100 patients (75%).

• The median duration of support was 126 days (range, 1 to 600).

• The survival rate during support was 75% at 6 months and 68% at 12 months.

• At 3 months, therapy was associated with significant

improvement in functional status (according to the New York Heart Association class and results of a 6-minute walk test) and in quality of life (according to the Minnesota Living with Heart Failure and Kansas City Cardiomyopathy questionnaires).

• Major adverse events included postoperative bleeding, stroke, right heart failure, and percutaneous lead infection.

• Pump thrombosis occurred in two patients.

1: Critical cardiogenic shock

2: Progressive decline

3: Stable but inotrope dependent

4: “recurrent” decompensation

5: comfortable at rest but are exercise intolerant for most activity

6: able to do some mild activity, but fatigue results within minutes with meaningful physical exertion.

7: NYHA Class IIIB

CHF and CAD and no symptoms of angina• Revascularisation has not been

shown to improve cardiac function or symptoms or to prevent reinfarction or death

• Appealing theoretical possibilities: imaging – myocardium that is viable but not contracting normally

PCI - Revascularisation = reasonable class IIa (B)• Significant lesions• Suitable for PCI and high likelihood

of success and low procedural risk• Vessels substending significant

area of viable myocardium or be associated with ischemia on noninvasive testing

Asymptomatic ischemia or CCS I or II

Poor LV-function CADCABG

Duke University Cardiovascular Database

• EF less than 0.35

• 10-year survival CABG 46 %

• 10-year survival medical therapy 27 %

Class I, level evidence: B

• Significant left main coronary artery stenosis or left main equivalent

• Proximal LAD with 2- or 3-vessel disease

Class III

• CABG should not be performed without evidence of intermittent ischemia and without evidence of significant revascularizable myocardium
