Randomized Controlled Trial Multicenter StudyDesign of a phase 2b trial of intracoronary administration of AAV1/SERCA2a in patients with advanced heart failure: the CUPID 2 trial (calcium up-regulation by percutaneous administration of gene therapy in cardiac disease phase 2b).
Impaired cardiac isoform of sarco(endo)plasmic reticulum Ca(2+) ATPase (SERCA2a) activity is a key abnormality in heart failure patients with reduced ejection fraction. The CUPID 2 (Calcium Up-Regulation by Percutaneous Administration of Gene Therapy in Cardiac Disease Phase 2b) trial is designed to evaluate whether increasing SERCA2a activity via gene therapy improves clinical outcome in these patients. ⋯ The CUPID 2 trial is designed to study the effects of this therapy on clinical outcome in these patients. (Calcium Up-Regulation by Percutaneous Administration of Gene Therapy in Cardiac Disease Phase 2b [CUPID-2b]; NCT01643330).

Randomized Controlled Trial Multicenter StudyPrognostic value of the physical examination in patients with heart failure and atrial fibrillation: insights from the AF-CHF trial (atrial fibrillation and chronic heart failure).
This study sought to assess the prognostic value of physical examination in a modern treated heart failure population. ⋯ In the modern era, congestive signs on the physical examination (i.e., peripheral edema, jugular venous distension, a third heart sound, and pulmonary rales) continue to provide important prognostic information in patients with congestive heart failure.

Randomized Controlled Trial Multicenter Study Comparative StudyDifferences in treatment, outcomes, and quality of life among patients with heart failure in Canada and the United States.
The aim of this study was to compare clinical outcomes, resource utilization, and health-related quality of life between Canadian and U.S. patients enrolled in ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure). A further aim was to supplement the within-trial analysis with a contemporaneous population-based comparison of all patients hospitalized with primary diagnoses of heart failure (HF) in the 2 countries. ⋯ Intercountry differences in outcomes of patients hospitalized with HF differed significantly between trial and population cohorts. Further study on how cardiac care is delivered in the 2 countries and how it influences the results of clinical trials and population-level outcomes, especially in the long term, is warranted. (A Study Testing the Effectiveness of Nesiritide in Patients With Acute Decompensated Heart Failure; NCT00475852).

Implant strategies change over time and impact outcomes: insights from the INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support).
This study investigated how the initial intended strategy at left ventricular assist device (LVAD) implantation influenced patient outcomes. ⋯ The currently accepted indications only account for 58% of LVAD implants. Across indications, patients differ by the number and types of comorbidities rather than the need for hemodynamic support. Regardless of initial implant strategy, patients often have long durations of support, and strategies often change over time, challenging the regulatory categorization of LVAD recipients as either BTT or DT.

Tubular damage and worsening renal function in chronic heart failure.
This study sought to investigate the relationship between tubular damage and worsening renal function (WRF) in chronic heart failure (HF) BACKGROUND: WRF is associated with poor outcome in chronic HF. It is unclear whether urinary tubular markers may identify patients at risk for WRF. ⋯ WRF was associated with strongly impaired outcome in patients with chronic HF. Increased level of urinary KIM-1 was the strongest independent predictor of WRF and could therefore be used to identify patients at risk for WRF and poor clinical outcome. (GISSI-HF-Effects of n-3 PUFA and Rosuvastatin on Mortality-Morbidity of Patients With Symptomatic CHF; NCT00336336).
