Filter by:This study is designed to evaluate the efficacy of Ferinject® in improving symptoms of CHF in patients with iron deficiency. Analyses will focus both on subjective and objective measures. Furthermore, the tolerability and safety of Ferinject® treatment will be evaluated.
The investigators test the hypothesis that different beta-blockers had a different influence on chemoreceptor response and lung diffusion capacity. Both could influence exercise capacity in normoxic as well as hypoxic conditions.
To evaluate the effects of CO2 inhalation and acetazolamide treatment on exercise-induced periodic breathing in patients with chronic stable heart failure. Patients will be given CO2 (2%) during a constant workload exercise. Patients will be also evaluated by maximal cardiopulmonary exercise test without and with acetazolamide acute and chronic treatment.
The purpose of this study was to assess whether Growth Hormone(GH)improves exercise capacity and cardiopulmonary performance in patients with chronic heart failure.
Patients showing a normal value of SDI (< or + 8%) will randomly be assigned to CRT in "ON" or "OFF"mode at one month after implantation. In any case of emergency, an automated rescue mode is included in the device for the patients in "OFF" mode.
In patients with chronic heart failure (CHF)due to dilated cardiomyopathy diastolic dysfunction occurs frequently and is related to a poor outcome. We have previously shown that parameters of diastolic function significantly correlate with uric acid levels, a marker of impaired oxidative metabolism. We aimed to determine whether inhibition of xanthine oxidase with allopurinol might affect diastolic function in patients with CHF.
To use continuous measurement of NT Pro BNP level as guide in therapy patients with CHF.
Background: Anemia in chronic heart failure (CHF) is directly linked to increased mortality and reduced exercise capacity. The pathomechanism for the development of anemia in CHF is not well understood. Impairment of iron homeostasis is discussed to be one of the major triggers in anemia of chronic disease. Hepcidin was recently described as the central regulator of iron homeostasis. Main hypothesis: Plasma hepcidin levels are altered in anemic CHF patients compared to non anemic controls and might be a main contributing factor of anemia in CHF. Iron regulator-hypothesis High levels of cytokines in CHF patients cause up-regulation of hepcidin, which in turn leads to low iron uptake causing anemia. In this case venous hepcidin and hemoglobin concentrations should both correlate with cytokine levels. Erythropoietin regulator-hypothesis Dysregulation of the erythropoietin system results in anemia, which represses hepcidin. This leads to a negative correlation between hemoglobin and hepcidin in plasma. Methods: 100 consecutive patients diagnosed with systolic CHF will be prospectively included in the study. Iron status will be assessed and hepcidin, erythropoietin as well as interleukin-1, interleukin-6 and soluble TNF alpha receptor levels will be measured by ELISA. Patients will be followed up for one year and mortality, rehospitalization and worsening of CHF will be documented.
The purpose of this study is to investigate whether an angiotensin II receptor blocker (olmesartan), in addition to conventional treatment, will reduce the mortality and morbidity in hypertensive patients with stable chronic heart failure.
To test whether treatment with the angiotensin II receptor antagonist Irbesartan improves insulin sensitivity and metabolic profile in patients with chronic heart failure.
