Arms Assigned Interventions
Experimental: Usual Care
Usual Care group will receive standard heart failure treatment based on the doctor's best judgment and following the recommendation of current guidelines. This will typically include the use of medicines such as beta-blockers, ACE-inhibitors, and diuretics, all of which are approved, recommended treatments for heart failure.
Other: Usual Care
Usual Care
Experimental: Biomarker-Guided Care
Device: Biomarker-Guided care NT-proBNP The Biomarker Guided Therapy group will receive the standard heart failure treatments. In addition, the doctor will use the results of a blood test called NT-proBNP to help adjust the treatments and drug doses.
Device: Biomarker-guided care NT-proBNP
Device: NT-proBNP

Detailed Description:
Heart failure is a common disorder in which the heart cannot pump enough blood to meet the needs of the rest of the body. Common symptoms of heart failure include shortness of breath, swelling, and fatigue. Standard treatment for heart failure include diuretics to control fluid, as well as drugs called "neurohormonal antagonists" (such as beta-blockers and ACE-inhibitors) that help the heart work more efficiently and prevent worsening of heart function. Typically, doctors adjust these medicines based on their clinical judgment about what doses and combination will work best for you. We are testing whether the use of a blood test called NT-proBNP (which measures a hormone released by the heart) can help doctors do a better job of adjusting these heart failure medicines over time than clinical judgment alone.
