The survival rate of cancer patients has greatly increased over the past decades' mainly due to early detection and the use of new medications with higher doses and combined protocols. This achievement comes with the price of cardio toxicity, leading to cardiac dysfunction ranged from transient asymptomatic left ventricular dysfunction to cardiac death. In the long term, the risk of death from cardiovascular causes exceeds that of tumor recurrence for many types of cancer. As a result of the increasing number of long-term cancer survivors the magnitude of this problem is growing. Early identification of cardio toxicity can be identified by clinical follow-up and the use of electrocardiography, cardiac biomarkers (Troponin, brain natriuretic peptide) and echocardiogram. Past studies imply that the addition of angiotensin-converting-enzyme inhibitor (ACE inhibitor) and beta blockers to the patient's treatment may prevent the development of cardiac dysfunction. However, currently there are no specific or clear guidelines for the follow-up and management of cardio-toxicity in cancer patients. The aim of the study: To try to identify who are the patients at increased risk for developing cardio toxicity, by follow up of clinical evaluation, cardiac biomarkers and echocardiogram examination, in purpose of early diagnosis, management and prevention of cardiac events. For achieving this the investigators will build a registry which will include all the oncologic patients going an evaluation in the cardio-oncology clinic in the Tel Aviv Medical Center .
Background: The wearable cardioverter defibrillator (WCD) is an established treatment option for patients at high risk for ventricular tachycardia / ventricular fibrillation (VT/VF), either in whom this risk may only be temporarily present, or in patients at high risk for sudden cardiac death (SCD) or after VT/VF in whom an implantable cardioverter defibrillator (ICD is currently not possible for other reasons (infection, recent MI <40days, recent PCI/CABG < 3months etc.). Methods: Comprehensive registry including all patients in Austria who received a WCD in 2010-2016.
Aim:To determine the baseline characteristics of heart failure patients in Singapore undergoing cardiac resynchronization therapy (CRT); the long term outcome and predictors of response to CRT. Methodology:Among patients undergoing CRT for severe heart failure according to indications stipulated in international Cardiology guidelines, baseline demographic data is collected. Age, gender, NYHA functional class, co-morbidities, QRS width on ECG, presence of left bundle branch block pattern on ECG, presence of atrial fibrillation, left ventricular ejection fraction (LVEF) on echocardiogram, ventricular dimensions, 6 min walk test distance are collected. In addition, during the CRT implant procedure, blood is drawn from the vascular access and analysed for NT-pro BNP levels and other biomarkers of heart failure. The echocardiographic and ECG parameters and blood biomarkers are reanalysed at 6 months and 12 months following CRT implant. Response to CRT is defined as a reduction in the iLVESV (left ventricular end-systolic volume index to body surface area) of >/= 15% and/or an increase in the LVEF of >/= 10%.
Heart failure (HF) is a serious chronic disease with frequent readmissions, some of which can be prevented by early action. The management of HF is complex: long, often difficult and costly. In France, nearly one million people suffer from HF and 120,000 new cases are diagnosed every year. With the aging population, this number will continue to evolve and become a real public health problem. Within 10 to 20 years ahead, WHO projects that heart failure in either the 3 most common diseases in industrialized countries. Investigators goals are to make an inventory of PRADO-IC project in terms of its effectiveness on readmission of patients with heart failure.
Digoxin was approved for heart failure treatment in 1998 according to current regulations made by Food and Drug Administration (FDA), based on the following clinical trials: The Prospective and Randomized Study of Ventricular Function and Efficacy of Digoxin (PROVED), Randomized Assessment of Digoxin on Inhibitors of the Angiotensin Converting Enzyme (RADIANCE) and Digitalis Investigation Group (DIG). Also, it was approved for the control of ventricular response rate in atrial fibrillation patients. Several clinical trials with digoxin provided convincing evidence that support the digoxin use heart failure (HF) treatment of symptomatic patients. PROVED trial was a placebo-controlled, twelve weeks duration study. This study included patients with decreased systolic function, sinus rhythm and heart failure stable symptoms, these patients were using digoxin and diuretics. Patients whom digoxin was removed presented a twice heart failure worsen, reduction of exercise capacity and also a reduction of left ventricle ejection fraction, in comparison to patients that kept the digoxin therapy. The study RADIANCE followed a similar protocol; however the patients used ACE inhibitors besides digoxin and diuretics. The digoxin removal was associated with a six times worsen of heart failure, despite the maintenance of ACE inhibitors and diuretics. There was a worsening in the functional capacity, life quality and in the ejection fraction on the digoxin removal patients' group.
This research aims to evaluate the effects of inspiratory muscle training (IMT) on apnea hypopnea index, sleepiness, sleep quality, cognitive function, motor task, executive function, quality of life, chemoreflex sensitivity and vagal modulation of heart rate in patients with heart failure and obstructive sleep apnea syndrome.
As the end stage of almost all cardiovascular diseases, heart failure has become an increasingly common cause of cardiovascular morbidity and mortality worldwide. In China, coronary artery disease (CAD) has become the main cause of heart failure in recent years. CAD combining with heart failure usually predicts poor outcome, with coronary revascularization the most universally used therapy. However, the difference of several types of such therapy has less well been compared. Thus, the study mainly aims to compare different types of coronary revascularization therapies such as Percutaneous Coronary Intervention (PCI),Coronary Artery Bypass Grafting (CABG) as well as Hybrid Coronary Revascularization (HCR), and also make the optimization strategy especially in patients with heart failure. The study also aims to investigate whether disease progression in patients with chronic heart failure (CHF) can be assessed by new biomarkers and determine their diagnostic and prognostic value, relating several cardiac functional parameters to clinical outcome.
Weight loss commonly occurs in patients with chronic heart failure (CHF) and chronic obstructive pulmonary disorder (COPD), negatively influencing their quality of life, treatment response and survival. Loss of muscle protein is generally a central component of weight loss in CHF and COPD patients, but patients also have reductions in fat mass and bone density, independent of the severity of the disease state. The purpose of this study is to provide detailed insight in disease related gut function by obtaining information on gut permeability, digestion and absorption of glucose, fat and protein in CHF and COPD patients compared to matched healthy controls. This will provide required information that is necessary to implement new strategies to develop optimal nutritional regimen in CHF and COPD.
A multi-centre, randomized, placebo controlled, trial. Participants at high-risk for vascular events from the network of INTER- CHF will be randomized to inactivated influenza vaccine or placebo and followed prospectively over three influenza seasons. 5,000 participants will be enrolled prior to influenza season, randomized to either influenza vaccine or saline placebo, either of which they will receive annually for three years and then followed over each of the influenza seasons.
