Details and patient eligibility

About

A pilot study to examine the effects of LDL-Apheresis on patients with Stage III Congestive Heart Failure.

Study hypothesis: Decreased blood viscosity from receiving LDL-apheresis will decrease workload on the heart and improve symptoms associated with the progression of Congestive Heart Failure

Full description

Patients who qualify for the study will receive 7 bi-weekly LDL-Apheresis treatments with the Kaneka Liposorber device. Patients will assess their CHF symptoms using the KC Cardiomyopathy questionnaire prior to each treatment. Blood levels of certain indices related to CHF and safety profile labs will be drawn before and after the first and last treatment.

Inclusion criteria

Male or Female, between the age of 18 and 85 years old. If female, must guarantee that pregnancy will not occur for duration of study
Presence of Left ventricular systolic dysfunction due to ischemic or non-ischemic cardiomyopathy and have symptoms of New York Heart Association Class III chronic Heart failure (CHF)
Left ventricular ejection fraction (LVEF) ≤ 35% as measured by radionuclide angiography
Subject must be on optimal conventional heart failure therapy including Beta-blocker in target or maximally tolerated doses for at least 3 months prior to entry into the study, and/or an angiotension receptor blocker (ARB) for at least 30 days prior to study entry. Subjects on ACE inhibitors, with approval of their physician, have been switched to an ARB one week before initiating apheresis
Other optimal conventional therapy have been taken for at least 30 days prior to initiation of apheresis
Subject is able to complete the 6-minute walk test and the Kansas City Congestive Heart Failure Quality of Life Questionnaire (KCCQ)
Not currently in, or planning to participate in other studies

Exclusion criteria

Age <18 years, or >85 years of age
Poor venous access
CHF due to, or associated with, uncorrected primary valvular disease, uncorrected thyroid disease, obstructive/hypertrophic cardiomyopathy, pericardial disease, amyloidosis, active myocarditis, malfunctioning artificial heart valve, uncorrected congenital heart disease, or primary pulmonary hypertension

Subject is listed for transplantation and is expected to be transplanted within 6 months of initiation of apheresis treatment
Subject has had a myocardial infarction within 6 months prior to initiation of apheresis treatment
Subject with electrocardiogram (ECG) recorded at initial screening showing particular abnormalities
Subject has sustained VT, unless precipitated by an event such as an acute myocardial infarction, induction by catheter replacement, or by an electrophysiology procedure, or addressed by placement of an automatic implantable cardiac defibrillator (AICD)

Subject is unable, or unwilling to change from an ACEI to an ARB
Subject has a known hypersensitivity to heparin or ethylene oxide
Subject has a known Low-density lipoprotein cholesterol (LDL-C) level of >130mg/dl
