Heart Failure With Normal Ejection Fraction Clinical Trial
Official title:
A PILOT TRIAL OF CELL THERAPY IN HEART FAILURE WITH PRESERVED EJECTION FRACTION
The primary objective of the study is to investigate safety and efficacy of transendocardial CD34+ cell therapy in patients with HFpEF by evaluating changes in myocardial structure and function, patient exercise capacity and clinical outcome. The safety end-points include serious adverse events (SAEs), defined as any serious event that may result in persistent or significant disability or incapacity and included death, heart transplantation, sustained ventricular arrhythmia (ventricular tachycardia or ventricular fibrillation), and heart failure exacerbation requiring hospitalization.
In all patients, peripheral blood stem cells will be mobilized by daily subcutaneous injections of G-CSF (10 mcg/kg, divided b.i.d) for 5 days. Peripheral blood stem cells will then be collected with Miltenyi cell separator (Miltenyi Biotech, Germany) and the magnetic cell separator Isolex 300i (Nexell Therapeutics Inc., California, USA) will be used for the immunomagnetic positive selection of the CD34+ cells. ;
