The purpose of this study is to evaluate a heart pressure system called the CardioMEMS PA Sensor (referred to as "the device") in patients with heart failure. A small sensor is threaded through a vein into your heart on the tip of a catheter, and may allow your health care team to determine fluid balance in your body. The CardioMEMS HF System is FDA approved for a select group of patients. The study plans to see if it works in more patients. The study will also learn if using the device's data for other indicators of heart failure might reduce worsening heart failure resulting in visits to the hospital to treat heart failure or death. You may be eligible if you are at risk of having episodes of worsening heart failure.More
1. Diagnosis and treatment for heart failure (HF) (regardless of left ventricular ejection fraction (LVEF)) for > 90 days prior to the date of consent: a. Subjects should be on stable, optimally titrated medical therapy for at least 30 days, as recommended according to current American Heart Association (AHA)/American College of Cardiology (ACC) guidelines as standard-of-care for HF therapy in the United States, with any intolerance documented. 2. GUIDE-HF Randomized Arm Only: NYHA Class II, III or IV HF symptoms documented within 30 days prior to consent. 3. GUIDE-HF Single Arm Only: NYHA Class III HF symptoms documented within 30 days prior to consent. 4. HF hospitalization (HFH) within 12 months prior to consent and/or elevated N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) (or Brain Natriuretic Peptide (BNP)) within 30 days prior to consent defined as: Subjects with LVEF ≤ 40%: NT-proBNP ≥ 1000 pg/mL (or BNP ≥ 250 pg/mL). Subjects with LVEF > 40%: NT-proBNP ≥ 700 pg/mL (or BNP ≥ 175 pg/mL). Thresholds for NT-proBNP and BNP (for both LVEF ≤ 40% and LVEF > 40%) will be corrected for body mass index (BMI) using a 4% reduction per BMI unit over 25 kg/m2 5. ≥ 18 years of age
