Filter by:To investigate the effect of hydralazine isosorbide dinitrate on clinical outcomes, symptoms, cardiac parameters and functional status of African patients hospitalized with AHF and left ventricular dysfunction during 24 weeks of therapy. Administration of hydralazine/nitrates will be superior to placebo administration in reducing HF readmission or death, improving dyspnoea, reducing blood pressure and brain natriuretic peptide (BNP) in African patients admitted with AHF and left ventricular dysfunction.
The primary objective is to test the hypothesis that, compared with placebo, therapy with Subcutaneous (SQ) GLP-1 agonist in the post-Acute Heart Failure Syndrome (AHFS) discharge period will be associated with greater clinical stability at six months as assessed by a composite clinical endpoint.
Patients being hospitalized for acute heart failure and already receiving standard therapy will be randomized to receive either tolvaptan or placebo, based on the level of copeptin measured in their bloodstream. Patients with high copeptin levels will be able to participate in the trial, patients with low levels will be excluded. Patients being admitted to the observation unit for acute heart failure and already receiving standard therapy will be randomized to receive either tolvaptan or placebo without consideration of the copeptin level. The hypothesis is that patients receiving tolvaptan will have better improvement of shortness of breath than those receiving placebo, within 9 hours of drug administration.
Levosimendan is a drug used in patients with heart failure and has several advantages over other heart failure drugs. A lot of research has been done with Levosimendan in Adults, and the way the body handles the drug (pharmacokinetics) and responds to the drug (pharmacodynamics) are well established. But, in children this information is lacking despite the fact that Levosimendan is increasingly used in children of all ages. The investigators aim to describe which Levosimendan dose leads to which drug levels in children of different ages.
The purpose of this study is to evaluate the efficacy and safety of recombinant human B-type natriuretic peptide (rhBNP) on heart and renal function in patients with acute decompensated heart failure (ADHF) and acute renal injury (AKI).
Left ventricular failure (LVF) is a common cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This association is frequently underestimated with regard to the difficulty of clinical diagnosis . The investigators expect that Valsalva Maneuver (VM) could be useful in this issue.
Acute heart failure (AHF) is defined as a gradual or rapid change in heart failure (HF) signs and symptoms, such as shortness of breath (also called dyspnea or breathlessness), leg swelling, fatigue, breathlessness with exertion, trouble sleeping flat at night, and weight gain resulting in a need for urgent therapy. AHF results in over 1 million hospitalizations every year, resulting in an enormous public health burden. Approximately 1/3rd of patients will either be re-hospitalized or die within three months, and the resultant financial costs are large. As such, improving outcomes for AHF patients is critically important. Shortness of breath is the most common reason why patients with AHF present to the ER. As such, understanding how severe this symptom is, how much it improves with current treatments is very important to both patients and physicians. The purpose of this study is to determine the degree to which your shortness of breath improves during the first few days of hospitalization and its association with how fast you are breathing.
Post-discharge mortality and re-hospitalization for acute heart failure (AHF) affects 15% and 30% of patients respectively, within 90 days. With over 1 million annual hospitalizations and a financial cost exceeding 20 billion dollars, AHF is a major public health burden. Yet no AHF therapy to date definitively reduces morbidity and mortality, and in stark contrast to heart attack patients, highly rated evidence in guidelines do not exist. Although AHF is a syndrome and not one disease, typical treatment of patients hospitalized with AHF suggests otherwise. Despite substantial differences among AHF patients, therapy is largely uniform; patients receive medicine to help get rid of excess volume and little else. Although decades of empirical use support the symptomatic benefits of traditional therapies, outcomes remain extremely poor. As opposed to the "one-size-fits-all‟ approach used unsuccessfully to date in clinical trials, identification of specific AHF patient sub-groups is critical, so that tailored therapies can be developed and tested. Preliminary data suggests that the neurohormone aldosterone may be detrimental in AHF patients. Furthermore, this hormone level appears to rise during hospitalization. The investigators therefore propose to identify specific AHF patient phenotypes associated with high serum aldosterone levels to subsequently address the hypothesis that early aldosterone blockade continued throughout hospitalization will decrease re-hospitalization and mortality. Specifically, the investigators hypothesize that AHF patients with elevated serum aldosterone levels have a distinct phenotype compared to those with lower or normal aldosterone levels. Specifically, they will be older, have a lower systolic blood pressure, lower EF, worse renal function, higher BNP, and previous hospitalization for HF.
This study will assess the hemodynamic effect of RLX030 infusion in subjects with acute heart failure. In addition safety and effects on renal function and biomarkers will be assessed.
The Gulf Heart Association (GHA) sponsored Gulf acute heart failure registry (Gulf CARE)is a multinational , multicentre, prospective, observational, hospital-based registry of patients with acute heart failure(AHF) with 3 month and one year follow-up. Study Hypothesis: Due to variations in age at presentation, risk factors for heart failure particularly high prevalence of rheumatic heart disease in certain Gulf countries, variable medical practices and heart failure management setup in the Gulf region, AHF patients in the Gulf states are expected to have different presentation and receive different management than patients in European countries resulting in different outcome. It is also hypothesized that there is considerable gap between heart failure management guidelines and clinical practices in the Gulf region.
