Pulmonary Artery Sensor System Pressure Monitoring to Improve Heart Failure (HF) Outcomes
Randomized, parallel group controlled study examines the effect of supporting the Heart failure supply through pulmonary arterial (PA) pressure measurement with the CardioMEMS™ HF system to hard endpoints, safety and quality of life. The target population consists of heart failure (HF) patients who have been predominantly in New York Heart Association (NYHA) Stage III for the past 30 days and at least once in the past 12 months for HF were admitted to hospital. All patients receive basic care, which is based on structured telephone contact (between the care center, patient and family doctor) to optimize guideline compliant therapy. In the intervention group a PA pressure sensor is (CardioMEMS™-HF Sensor) implanted. These patients are structured by specially trained non-medical personnel aftercare with additional inclusion of the PA pressure values: adjusted to the basis of the information collected in PA monitoring the therapy is optimized. The follow-up period until the primary endpoint is 12 months.
• Written consent received from the patient or a legal representative after the in-formation has been provided.
• ≥≥ 18 years of age.
• Predominant symptoms in NYHA Stage III in the 30-day period prior to consent to the study.
• Objectified HF diagnosis for more than three months.
• Hospitalisation within 12 months prior to inclusion due to deterioration of HF symptoms.
• Able to tolerate dual antiplatelet therapy or anticoagulation therapy for one month after sensor implantation
• Patients with reduced left ventricular ejection fraction (LVEF) ≤40% (diagnosed within 6 months prior to inclusion) must be treated with guideline-compliant HF pharmacotherapy; if one class of guideline-compliant medication is not tolerated, appropriate documentation must be supplied; patients must receive and tolerate at least one class of guideline-compliant medication; if no guideline-compliant medication is tolerated at all, the patient may not participate in the study.
• In patients with preserved LVEF (\>40%; diagnosed within 6 months prior to inclu-sion) comorbidities must be treated in accordance with guideline-compliant medi-cation.
• Chest circumference (measured at axillary level) of less than 165 cm if BMI \>35 kg/m2.
⁃ Willing and mentally and physically able to meet the requirements for follow-up and long-term basic care (this includes the long-term willingness of the patient, and of their relatives where relevant, to participate in PA pressure-based monitor-ing).
⁃ Appropriate domestic situation, defined as being accessible by telephone (via fixed or mobile network) .
⁃ For the intervention group: Implantation is only performed if the diameter of the pulmonary artery branch intended for implantation is ≥7 mm (assessment will be made during the right heart catheterization)
