Comparison of effectiveness and survival after the MitraClip or Carillon procedure for severe functional mitral regurgitation: a single-center retrospective analysis.

Introduction: Current studies suggest improved survival in patients with severe functional mitral regurgitation (FMR) treated successfully with the MitraClip (MC) compared to medical treatment alone, in addition to a significant reduction of FMR severity. Recently, the Carillon system (CS) has also been shown to significantly reduce FMR. However, whether this beneficial effect of CS also translates into a survival benefit comparable to the MC system has not been investigated so far.

Comparison of interventional and surgical myocardial revascularization in kidney transplant recipients - A single-centre retrospective analysis.

Background: Kidney transplant recipients (KTR) reflect a high-risk population for coronary artery disease (CAD). CAD is the most common cause for morbidity and mortality in this population. However, only few data are available on the favourable revascularization strategy for these patients as they were often excluded from studies and not mentioned in guidelines.

Minute Myocardial Injury as Measured by High-Sensitive Troponin T Serum Levels Predicts the Response to Intracoronary Infusion of Bone Marrow-Derived Mononuclear Cells in Patients With Stable Chronic Post-Infarction Heart Failure: Insights From the TOPCARE-CHD Registry.

Rationale: Cell-based therapies are a promising option in patients with chronic postinfarction heart failure (ischemic cardiomyopathy [ICM]). However, the responses after intracoronary infusion of autologous bone marrow-derived mononuclear cells (BMCs) are heterogeneous, which may be related to impaired cell retention in patients with ICM. Ischemic injury is associated with upregulation of prototypical chemoattractant cytokines mediating retention and homing of circulating cells.

Impact of intracoronary reinfusion of bone marrow-derived mononuclear progenitor cells on cardiopulmonary exercise capacity in patients with chronic postinfarction heart failure.

Introduction: Intracoronary infusion of bone marrow-derived progenitor cells (BMC) in patients with chronic ischaemic heart failure (CHF) is associated with improvement in left ventricular ejection fraction (LVEF), reduction of NT-proBNP levels and improved prognosis. However, effects of this therapy on cardiopulmonary exercise capacity have not been investigated separately so far.

Patients And Methods: One hundred and fifty-four patients with ischaemic heart failure (mean LVEF 40.

Comparison of the Seattle heart failure model and cardiopulmonary exercise capacity for prediction of death in patients with chronic ischemic heart failure and intracoronary progenitor cell application.

Background: Despite many therapeutic advances, the prognosis of patients with chronic heart failure (CHF) remains poor. Therefore, reliable identification of high-risk patients with poor prognosis is of utmost importance. Cardiopulmonary exercise testing (CPET) provides important prognostic information by peak O2 uptake (peak VO2 ), maximal oxygen pulse (O2 Pmax), O2 uptake efficiency slope (OUES), and VE/VCO2 slope (VE/VCO2 ).

G-CSF stimulation and coronary reinfusion of mobilized circulating mononuclear proangiogenic cells in patients with chronic ischemic heart disease:five-year results of the TOPCARE-G-CSF trial.

Prognosis of patients with heart failure remains poor despite improved conventional and interventional treatment regimens. The improvement of neovascularization and repair processes by administration of bone marrow-derived cells modestly improved the recovery after acute myocardial infarction. However, circulating patient-derived cells are reduced in number and function particularly in chronic heart failure.

The initial slope of the VCO2/VO2-curve (s1) in cardiopulmonary exercise testing is a strong and independent predictor of outcome in patients with previous myocardial infarction.

Background: Detecting heart failure (HF) patients at risk is a relevant clinical problem. Our goal was to define associations of clinical HF-markers and exercise parameters with respect to their prognostic power in HF-patients.

Methods: We performed cardiopulmonary exercise testing (CPET) in 103 ischemic HF-patients.

Ex vivo pretreatment of bone marrow mononuclear cells with endothelial NO synthase enhancer AVE9488 enhances their functional activity for cell therapy.

Bone marrow mononuclear cells (BMC) from patients with ischemic cardiomyopathy (ICMP) show a reduced neovascularization capacity in vivo. NO plays an important role in neovascularization, and NO bioavailability is typically reduced in patients with ICMP. We investigated whether the impaired neovascularization capacity of ICMP patient-derived progenitor cells can be restored by pretreatment with the novel endothelial NO synthase (eNOS) transcription enhancer AVE9488 (AVE).

Effects of granulocyte colony simulating factor on functional activities of endothelial progenitor cells in patients with chronic ischemic heart disease.

Objective: Bone marrow-derived circulating endothelial progenitor cells (EPCs) may contribute to regeneration of infarcted myocardium and enhance neovascularization. Granulocyte colony-stimulating factor (G-CSF) is well-established to mobilize hematopoietic stem cells (HSCs) and might, thereby, also increase the pool of endogenously circulating EPC. Therefore, we investigated the effects of G-CSF administration on mobilization and functional activities of blood-derived EPC in patients with chronic ischemic heart disease (CIHD).
