Filter by:This study hypothesis is that Semaphorins 3A and 4D levels are overexpressed in patients with heart failure. Study protocol: Hospitallized patients with new onset or previously diagnosed heart failure will be recruited to the study. Control group will include healthy people with no medical records or chronic treatment at the same age range. After signing an informed constent form, full medical history and blood samples will be collected. A second blood sample will be collected 8 weeks later, assuming the patient was discharged and not hospitalized since than. The blood samples will be analyzed by Bnai Zion Medical Center Immunology labs for the above semaphorins levels in the heart failure group and control group. Statistical analysis will then commence for possible correlatoion with different clinical parameters.
The purpose of this study is to assess the impact of the Multi Point Pacing (MPP) feature in the treatment of patients with QRS beetwen 100 and 130 msec in patients candidate to ICD implant.
Cardiac resynchronisation therapy (CRT) prolongs the life and improves the symptoms in patients with heart failure and electrical dyssynchrony. 30-50% of patients do not improve with the treatment which is both expensive and not without complication. Despite much research, we cannot accurately predict who will not respond. Furthermore, most heart failure patients gets symptoms on exercise and most studies have examined patients at rest. We propose to investigate the effect of exercise on different parts of the left ventricle by sampling various biomarkers of metabolism, myocardial injury and gene expression. We will then repeat the protocol following device insertion to look for changes. This novel work will require a small cohort of patients with heart failure and no electrical dyssynchrony and normal patients to act as controls. We will also measure novel biomarkers at different venous sites relating to different parts of the myocardium to determine whether they can be used to prognosticate or even predict response to CRT.
The study evaluates the efficacy of heart function improvements in type 2 diabetes and heart failure patients with exenatide, and also investigates the mechanisms of exenatide improving heart function.
The study is intended to verify the safety and assess the performance of up to 3-days treatment protocol with the RenaSense System in ADHF patients.
This is multicentre, randomised open-label, controlled, parallel-group phase III study. Its aim is to demonstrate that a triple intracoronary infusion of autologous bone marrow-derived mononuclear cells in addition to state of the art treatment is safe and reduces all-cause mortality in patients with reduced left ventricular ejection fraction (≤45%) after successful reperfusion for acute myocardial infarction when compared to a control group of patients undergoing best medical care.
This study is designed to evaluate the efficacy and safety of the C3BS-CQR-1 in the treatment of patients with chronic heart failure secondary to ischemic cardiomyopathy.
The purpose of this study is to determine the safety and benefits of SG1002, including overcoming deficits in circulating hydrogen sulfide and nitrite found in heart failure patients, with secondary endpoints focused on improving clinical endpoints.
Heart failure is the most rapidly growing cardiovascular condition in developed countries. Despite advances in medical therapy, patients with heart failure are at high risk for death and hospitalization. Cardiac Resynchronization Therapy - defibrillators (CRT-D) are an effective treatment for heart failure. Despite the high success rate of a CRT-D implant, there is a possibility of 10% that the LV lead cannot be implanted in patients undergoing a trans-venous system implantation. In this case, the patients may undergo multiple procedures before a lead is successfully implanted. These implant failures are not due to patient selection but rather to patients heart anatomy leading to lead stability problems, phrenic nerve stimulation (also called diaphragmatic stimulation) and poor electrical measurements. The phrenic nerve is not part of the heart but runs near to this area on the way to a large muscle, called diaphragm, which separates the lung space from the space containing stomach, liver, kidneys and other internal organs in the abdomen. If the lead electrode is close to this nerve, it can cause a small part of it to contract giving you an uncomfortable hiccupping sensation. In many patients, phrenic nerve stimulation is not identified until after the implant procedure when movement and postural changes bring the LV lead into closer contact with the phrenic nerve. The investigation is performed to demonstrate the equality of performance of two different modalities of optimization of the implanted device and Quartet lead, Empirical (anatomical) optimization and Right Ventricle Left Ventricle (RVLV) conduction delay optimization.
The purpose of this study is to determine the role of ivabradine in cardiac resynchronization recipients with an unsatisfactory percentage biventricular pacing. The study protocol 60 patients with heart failure NYHA (New York Heart Association) II-IV treated with optimal medical therapy as clinically indicated who received CRT-D device more than 3 months ago. Patients with biventricular pacing <95% will and heart rate <70 at rest and >50% of heart rate in device memory >70 will receive ivabradine. The minimal follow-up of patients in the study will be at least six months.
