Long-term Quality-of-Life (QoL) in patients with progressive chronic heart failure after surgical ventricular restoration with passive ventricular constraint (CorCap-CSDTM): Comparison with a patient-matched reference group from the general population
(English)Manuscript (preprint) (Other academic)
Background: Chronic heart failure have a poor prognosis with high morbidity and reduced quality of life. Ventricular constraint, the CorCap Cardiac Support Device (CSD) has been introduced with the intention of inducing reverse remodeling. Studies have shown sustained improvement in left ventricular dimensions and function after three years, but quality-of-life (QoL) has been poorly studied.
Methods and Results: Since 2003, 26 patients with chronic progressive heart failure met the inclusion criteria for CSD. They were prospectively followed each year for five years postoperatively. Nineteen patients were scheduled for concomitant cardiac surgery.
In a cross-sectional study, 18 patients were investigated regarding QoL using SF-36. A reference group was randomly selected from the Swedish SF-36 general population reference group.
One-year survival for CSD-patients was 86%, three-year survival was 76%. After a mean follow-up time after surgery of 3.9 years (range; 0.9 to 7 years), no difference in QoL measured with SF-36 was found. Echocardiographic dimensions and QoL improved significantly after three years for isolated CSD patients.
Conclusions: QoL in patients operated with CSD, measured with SF-36-questionnaire, more than three years after implantation, is comparable to a matched general population reference group. In the CSD group alone, QoL improved significantly after three years.
