Cardiac Rhythm Monitoring After Acute Decompensation for Heart Failure

Cardiac Rhythm Monitoring After Acute Decompensation for Heart Failure

The CARRYING ON for heart failure (HF) study is a national, prospective, post market interventional, multi-center, open-label, pilot trial.The purpose of the study is to assess a short term and a long term period, incidence of pre-specified clinical and arrhythmic events in patients with a low ejection fraction (EF) that are hospitalized for acute cardiac decompensation.

The CARRYING ON for heart failure (HF) study is a national, prospective, post market interventional, multi-center, open-label, pilot trial designed in two phases.

The purpose of the study is to assess a short term (6 months follow-up - Phase 1) and a long term period (24 months follow-up - Phase 2), incidence of pre-specified clinical and arrhythmic events in patients with a low ejection fraction (EF) that are hospitalized for acute cardiac decompensation. A previously implanted Reveal® XT device will be used to collect heart rhythm information.

Inclusion Criteria:

• Subject has an implanted Reveal® XT device (less than 15 days post implant);
• Ejection Fraction (EF) less than 40 percent
• Patient with access to a telephone line
• Patient or the patient's caregiver is willing and able to use the Medtronic CareLink® Network Monitor and to perform the required duties at home or has a family member or assistant perform those duties
• Age greater than 18 years old
• Patient is willing and able to comply with the Clinical Investigation plan and willing to remain available for follow-up visit, through study closure
• Patient (or patient's legally authorized representative) is willing and able to sign and date the study Informed Consent

Exclusion Criteria:

• New York Heart Association (NYHA) Class IV (chronic or ambulatory)
