Impact of Therapy Optimization on the Level of Biomarkers in Patients With Decompensated Heart Failure

Inclusion criteria

• Male or female patients ≥ 18 years.
• Hospitalized for ADHF or decompensated chronic heart failure. Patients who develop ADHF while hospitalized for another reason are not eligible.
• The underlying primary etiology for decompensation should be cardiac rather than pulmonary disease. For this study, all of the following must be observable at the time of screening:

• Dyspnea at rest (sitting or supine) or with minimal exertion (such as talking, eating, etc.) - NYHA III/IV;
• Pulmonary congestion on physical examination or chest x-ray;
• Able to begin study within 24 hours from presentation to the hospital, including time spent in the emergency department.
• Be adequately informed of the nature and risks of the study and give written informed consent prior to study start.

Exclusion criteria

• Acute or suspected acute myocardial infarction (AMI) or troponin levels > 3x the upper limit of normal. at the institution's local laboratory.
• Cardiogenic shock.
• Temperature > 38°C (oral or equivalent), sepsis or active infection requiring IV antimicrobial treatment.
• ADHF due to significant arrhythmias (ventricular tachycardia, bradyarrhythmias with ventricular rate < 45 bpm or atrial fibrillation/flutter with ventricular response of > 150 bpm).
• Current or planned ultrafiltration, hemofiltration, or dialysis.
• Significant pulmonary disease (history of oral daily steroid dependency, history of CO2 retention or need for intubation for acute exacerbation, or currently receiving IV steroids), or thoracic cage injury which compromises breathing.
• Any organ transplant recipient or patients currently listed or admitted for transplantation.
• Acute myocarditis or hypertrophic obstructive, restrictive, or constrictive cardiomyopathy (not including restrictive mitral valve filling patterns).
• Women who are pregnant or breastfeeding.
• Malignant disease with a life expectancy of less than two years.
• Autoimmune disease.
• Any condition or treatment of a condition which, in the opinion of the investigator, could interfere with the conduct of the study, or which would unacceptably increase the risk of the patient's participation in the study. This may include, but is not limited to, alcoholism, drug dependency or abuse, other severe mental disorders, epilepsy, or any unexplained episodes of syncope.
