Active clinical trials for "Heart Failure"

The purpose of this study is to assess the pharmacokinetics (ie, how the body affects the drug) and pharmacodynamics (ie, how the drug affects the body) of JNJ-54452840 in participants with heart failure and anti-beta1-adrenergic receptor autoantibodies. The safety and tolerability of JNJ-54452840 will also be assessed.

The purpose of this study is to evaluate if carvedilol can prevent the cardiotoxicity after chemotherapy in breast cancer.

Heart failure with preserved ejection fraction (HFPEF) is common and is a real public health issue. Diagnosis, especially when there are no congestive signs, is difficult. It has been shown that many patients with suspected HFPEF had left ventricular (LV) filling pressures elevated only at exercise (normal at rest). Using stress echocardiography and taking into account left atrial (LA) remodeling at rest as a "memory" of chronic elevation of filling pressures. We believe that it is possible to improve the noninvasive diagnosis of exercise elevation of the LV end-diastolic pressure (LVEDP).

External measure of thoracic fluid content (TFC) combined with vital signs (HR,respiratory rate(RR), posture and movements) using the technology developed by Kyma Medical Technologies while tracking clinical changes in acute in-hospital and chronic outpatient heart failure patients.

The optimal pacing rate during cardiac resynchronization therapy (CRT) is not known. Investigators investigate the impact of changing basal pacing frequencies on autonomic nerve function, cardiopulmonary exercise capacity and self-perceived quality of life (QoL).

The purpose of this study is to evaluate the efficacy and safety of rivaroxaban compared with placebo in the prevention of symptomatic venous thromboembolism (VTE) events and VTE-related death post-hospital discharge in high-risk, medically ill patients.

It is hypothesized that it is both safe and feasible to use an interventional approach to LV lead placement (placing the LV lead guided by acute hemodynamic measurements), and that the LV lead can be placed in a position that is superior to the initial empiric lateral wall LV lead location in less than 30 minutes without significant risk to patients. The time from RV capture to LV activation correlates with the optimal pacing site based on stroke volume & dP/dt measurements.

Background: The prevalence of heart failure (HF) is rapidly rising in industrialized and developing countries. Though invasive coronary angiography (ICA) remains the gold standard for anatomical assessment of coronary arteries and luminal stenoses in these patients, alternatives have been sought. Computed tomographic coronary angiography (CTA) has emerged as an accurate non-invasive diagnostic tool for CAD and has been demonstrated to have prognostic value. Whether or not CTA can be used in patients with HF for diagnosis and to guide patient investigations and management is unknown. Acknowledging the aging population in industrialized counties, the increasing burden of healthcare and growing prevalence of HF, there is a need to identify non-invasive diagnostic tests that are cost-effective, readily available, safe and of sufficient accuracy to risk stratify patients and guide investigations and management. Methods: The proposed randomized controlled trial (RCT) will evaluate the clinical utility of computed tomographic coronary angiography (CTA) and investigate its potential benefit on resource utilization and health economics in patients with progressive or newly diagnosed heart failure (HF) of unknown etiology (i.e. ischemic versus non- ischemic) or in whom the definition of coronary anatomy is required for diagnosis and management. The experimental algorithm will be compared to invasive coronary angiography (ICA) Analysis of composite clinical events and major adverse cardiac events will be performed to determine the impact of these strategies upon patient outcomes. Accuracy of CTA in detection of coronary anatomy and obstruction will be assessed in patients undergoing ICA. It is expected that CTA will be a more cost-effective strategy for diagnosis; yielding similar outcomes with fewer procedural risks and improved resource utilization.

Although many studies have demonstrated the efficacy of disease management programs on mortality, morbidity, quality of life (Qol), and medical cost in patients with heart failure (HF), no study has focused on psychological status as an outcome of disease management in patients with HF. Disease management could lead to the reduction of psychological distress, thus improving the self-care ability and adherence of patients with HF. In addition, very little information is available on the effectiveness of disease management programs in areas other than the US and Europe.The Japanese Heart Failure Outpatients Disease Management and Cardiac Evaluation (J-HOMECARE) has designed a randomized controlled trial to evaluate the efficacy of home-based disease management programs compared with usual care in improving psychosocial status, mortality, HF hospitalization, and Qol in Japanese HF patients.

The purpose of this study is to assess the impact of a multidisciplinary team clinic including a clinical pharmacist, a registered nurse (RN), dietician and physician providing short-term sub-acute management of patients with heart failure on patient outcomes and the quality of medication use. Patients being discharged from the emergency department with a diagnosis of heart failure will be eligible for this study. We believe that emergency room visits, hospitalization and deaths secondary to heart failure will decrease secondary to this program.
