365 A nurse-led out-patient intravenous infusion of dobutamine program is a cost-effective approach in patients with end-stage heart failure followed in a heart failure day hospital: a pilot study

Background: Dyspnea is distressing in palliative patients with end-stage heart failure and many are hospitalized to optimize this symptom. We hoped to conduct a pilot study to determine whether the administration of intranasal fentanyl would decrease activity-induced dyspnea in this patient population. Methods: Patients performed two 6-minute walk tests with and without the administration of 50 μg of intranasal fentanyl. Vital signs were recorded before and after each walk, as were participant reported dyspnea and adverse events scores. Results: Twenty-four patients were screened, 13 were deemed eligible, and 6 completed the study. Dyspnea scores changed from a mean of 6.00 immediately after the walk without fentanyl to a mean of 3.83 after the walk with fentanyl ( P = .048). Mean respiratory rate decreased from 21.0 to 18.7 ( P = .034) breaths per minute and was considered a favorable outcome by the participants. Distance walked did not significantly increase with the fentanyl pretreatment (136.0-144.2 m; P = .283), although the participants reported feeling better while walking a similar distance. Conclusions: In this pilot study, the preadministration of intranasal fentanyl prior to activity in palliative, end-stage hospitalized heart failure patients, safely reduced tachypnea, and the feeling of shortness of breath. This approach may help palliate advanced heart failure patients by alleviating symptoms brought on by exertional activities.

Endothelial Nitric Oxide

Nitric oxide (NO) is a potent endothelium-derived relaxing factor which also may modulate cardiomyocyte inotropism and growth via increasing cGMP. While endothelial nitric oxide synthase (eNOS) isoforms have been detected in non-human mammalian tissues, expression and localization of eNOS in the normal and failing human myocardium are poorly defined. Therefore, the present study was designed to investigate eNOS in human cardiac tissues in the presence and absence of congestive heart failure (CHF).Normal and failing atrial tissue were obtained from six cardiac donors and six end-stage heart failure patients undergoing primary cardiac transplantation. ENOS protein expression and localization was investigated utilizing Western blot analysis and immunohistochemical staining with the polyclonal rabbit antibody to eNOS (Transduction Laboratories, Lexington, Kentucky).
