In two interim analyses of this trial, patients with advanced heart failure who were treated a fully magnetically levitated centrifugal-flow left ventricular assist device less likely to have pump thrombosis or nondisabling stroke than mechanical-bearing axial-flow device.We randomly assigned receive either the irrespective intended goal use (bridge transplantation destination therapy). The composite primary end point was survival at 2 years free disabling reoperation replace remove...
Background Most patients with heart failure are currently managed by physicians little specific expertise in failure. This management system has been associated evidence of suboptimal care, such as high rates hospital readmission and underuse ACE inhibitors. The current study was undertaken to determine whether hospitalization functional outcomes improved when special working a dedicated program. Methods Results All referred the Vanderbilt Heart Failure Transplantation Program between July...
Peak exercise oxygen consumption (Vo2), a noninvasive index of peak cardiac output (CO), is widely used to select candidates for heart transplantation. However, Vo2 can be influenced by noncardiac factors such as deconditioning, motivation, or body composition and may yield misleading prognostic information. Direct measurement the CO response avoid this problem more accurately predict prognosis.Hemodynamic ventilatory responses maximal treadmill were measured in 185 ambulatory patients with...
Background In patients with heart failure, excessive sympathetic activation during exercise could interfere performance by impairing arteriolar dilation in working muscle and adversely altering skeletal metabolic behavior. To test this hypothesis, we examined the effect of sympathoinhibition clonidine, a central sympatholytic agent, on blood flow metabolism failure. Methods Results Swan-Ganz femoral venous catheters were inserted 20 chronic failure intolerance (peak V̇ o 2 =9.3±1.4 [SEM]...

Heart failure disproportionately affects Black patients. Whether differences among race influence outcomes in advanced heart with use of a fully magnetically levitated continuous-flow left ventricular assist device remains uncertain. We included 515 IDE (Investigational Device Exemption) clinical trial patients and 500 Continued Access Protocol implanted the HeartMate 3 MOMENTUM study (Multicenter Study MagLev Technology Patients Undergoing Mechanical Circulatory Support Therapy With 3)....

Electronic home monitoring for chronic heart failure is emerging as an available option to add our armamentarium a vital part of the multidisciplinary care process. This investigation describes early clinical results multicenter study that suggests important trends in medical resource utilization may be attained by use this modality. (c)2000 CHF, Inc.
