The primary objective of the study is to compare efficacy of metolazone and chlorothiazide as add-on therapy in patients refractory to loop diuretics with heart failure with a reduced ejection fraction (HFrEF). This will be a single-center randomized pilot study.
Cardiac surgery can be not infrequently complicated by cardiac low-output syndrome due to critical preoperative conditions such as cardiogenic shock, poor left ventricular function and severe myocardial ischemia. Suboptimal myocardial protection, technical errors at graft anastomoses or of prosthesis implantation, and hibernating myocardium may further contribute to cardiac low-output syndrome occurring immediately or shortly after cardiac surgery. In this setting, veno-arterial extracorporeal oxygenation (VA-ECMO) is the only means to provide cardiopulmonary support to recovery or as bridge to transplantation. Data on the real benefit of VA-ECMO after cardiac surgery is limited and often derived from heterogeneous patient populations, which prevent conclusive results on the benefits of VA-ECMO in this setting. This issue will be investigated in the present retrospective European multicenter study. In this setting, veno-arterial extracorporeal oxygenation (VA-ECMO) is the only means to provide cardiopulmonary support to recovery or as bridge to transplantation. Data on the real benefit of VA-ECMO after cardiac surgery is limited and often derived from heterogeneous populations of patients who underwent different cardiac procedures. Patients with cardiac low-output after surgery for aortic dissection or valve surgery are expected to have different baseline characteristics (such as age and comorbidities) and underlying cardiac disease than patients undergoing isolated coronary surgery. Furthermore, available studies included patients operated during the nineties and this does not provide an exact measure of the benefits of this treatment strategy. The possible benefits of using VA-ECMO after adult cardiac surgery will be investigated in this retrospective European multicenter study.
The purpose of this research is to develop patient-centered palliative care interventions to improve patient-provider communication and Quality of Life (QoL) of ethnic and racial minority patients living with life-limiting illnesses. Eliciting personal experiences is an effective way for patients to communicate their cultural values and beliefs. This study will assess how to integrate the patients' personal experience narratives into the electronic health record (EHR). The primary hypothesis is that the implementation of a patient-centered intervention to elicit personal experiences that are included in the EHR will improve patient-provider communication and patients' QoL.
The DERIVATE study was conceived to integrate the information resulted from clinical data, transthoracic echocardiography, and cardiac magnetic resonance (CMR) imaging to provide a more reliable risk stratification in patients affected by heart failure (HF) and worthy of prophylactic implanted cardioverter defibrillator (ICD) therapy. The main purposes of this multicenter registry are to: 1) determine CMR findings, and specifically late gadolinium enhancement (LGE) features, T1 mapping, and extracellular volume (ECV) that predict sudden cardiac death (SCD) and ventricular arrhythmia; 2) provide a comprehensive clinical and imaging score that effectively improves the selection of patients who deserve a prophylactic ICD therapy; 3) evaluate the contribution of machine learning to predict major adverse cardiac events (MACE) as compared to standard clinical scores.
This retrospective observation is to investigate the incidence,clinical outcomes and prognosis of hospitalized heart failure with preserved ejection fraction (HFpEF) in patients with acute myocardial infarction(AMI).
This study aims to assess the effectiveness of a social incentive-based gamification intervention to increase physical activity in the 3 months after hospital discharge.
This VA QUERI Partnered Evaluation Initiative will evaluate the impact of an immersive Point-of-care Ultrasound (POCUS) Training Course on provider skill acquisition and retention; the frequency of POCUS use by trained providers; and the barriers/facilitators to POCUS in the VHA. Data sources include pre- and post-course assessment tools, medical coding data, and course evaluations. Providers that participate in the POCUS Training Course will be compared to control providers from wait-listed facilities. Additionally, participating facilities vs. wait-listed facilities for the POCUS Training Course will be compared. Findings from this project will guide ongoing efforts of the investigators' operating partners, VA Specialty Care Centers of Innovation (SCCI) and the VA Simulation Learning and Research Network (SimLEARN), to develop a national POCUS training program and facilitate implementation of POCUS use system-wide in the VA healthcare system.
The objective of this study is to determine ventricular loading conditions during and after PulseCath® iVAC2L support, and assess its impact on specific load dependent humoral factors and cardiac enzymes. These specific patterns are so far unknown and will be compared with the validated FDA-cleared and CE marked Impella CP. Ten cases with Impella CP will be performed in this study to obtain the exact same measurements for comparing purposes.
There are always poor outcomes in patients with acute myocardial infarction(AMI) combined with elevated BNP/NT-proBNP level. An elevated BNP/NT-proBNP level highly indicates acute heart failure(AHF).Levosimendan is recommended in many clinical trials of heart failure and Chinese heart failure guidelines. As a result, the investigators form a hypothesis that when patients with AMI combined with elevated BNP/NT-proBNP level are in conditions before AHF, to use levosimendan may reduces the risk of heart failure and improve the outcome.
This study will be a randomized open-label pilot study. The purpose of the study is to compare standard of care outpatient heart failure management versus a weight based torsemide regimen. Subjects admitted to the hospital for heart failure exacerbation will be randomized upon discharge to either standard of care outpatient heart failure management or a weight based torsemide regimen. Those subjects randomized to standard of care therapy will be prescribed a daily fixed dose of a loop diuretic at hospital discharge and have a follow-up appointment within one week of discharge. All management decisions including loop diuretic type, dose and frequency will be made at the discretion of the subject's personal physician. Those randomized to an individualized weight based torsemide regimen will be prescribed a dose of torsemide upon hospital discharge based on a prespecified algorithm. These subjects will then undergo physician-subject phone encounters three times a week where the subject's torsemide dose will be modified based on the prespecified algorithm which incorporates current symptoms and weight. Primary end-point will be an unbiased estimate of 30-day all cause readmission rates. Secondary end-points include incidence of acute kidney injury, changes in brain natriuretic peptide levels from baseline and a preliminary estimate of the effect size and feasibility of a weight-based torsemide regimen intervention in order to plan a future larger study.
