NCT00827801
Primary Objective: To determine if there is a reduction in the mean symptom severity scores for the heart failure specific symptom items between baseline and at the end of three months between patients whose symptoms are managed using the MDASI-HF symptom assessment scores (treatment group) as a decision making guide, as compared to patients managed without using the MDASI-HF symptom assessment scores (control group). Secondary Objectives: 1. Examine the correlation between mean symptom severity scores and the secondary endpoints of: a) exercise tolerance ( 6-minute walk), b) NYHA (New York Heart Association) functional classification, c) B-type natriuretic peptide (a biomarker for heart failure), and d) dose titration of HF (heart failure) medications. 2. Define symptom severity critical values in cancer patients with concurrent heart failure that trigger clinical intervention 3. Identify symptom clusters which may occur in cancer patients with concurrent heart failure.
NCT00291551
This is a limited safety and feasibility study to evaluate the PVSS Introducer and Paracor Ventricular Support System when used to treat patients with heart failure. The implant, which is loaded onto the delivery system, is placed over the epicardial surface of the right and left ventricles. No formal hypothesis testing will be performed; descriptive statistics will be used to summarize patient outcomes. The results of the study will be used to guide the design and sample size estimation of future studies.
