Novel Nebulized Milrinone Formulation for the Treatment of Acute Heart Failure Requiring Inotropic Therapy: A Phase 1 Study. J Card Fail 2024; 30:329-336. [PMID: 37871843 DOI: 10.1016/j.cardfail.2023.08.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 07/24/2023] [Accepted: 08/07/2023] [Indexed: 10/25/2023]
Abstract
BACKGROUND Nonintravenous inotropic-delivery options are needed for patients with inotropic-dependent heart failure (HF) to reduce the costs, infections and thrombotic risks associated with chronic central venous catheters and home infusion services. METHODS We developed a novel, concentrated formulation of nebulized milrinone for inhalation and evaluated the feasibility, safety and pharmacokinetic profile in a prospective, single-arm, phase I clinical trial. We enrolled 10 patients with stage D HF requiring inotropic therapy during a hospital admission for acute HF. Milrinone 60 mg/4 mL was inhaled via nebulization 3 times daily for 48 hours. The coprimary outcomes were adverse events and pharmacokinetic profiles of inhaled milrinone. Acute changes in hemodynamic parameters were secondary outcomes. RESULTS A concentrated nebulized milrinone formulation was well tolerated, without hypotensive events, arrhythmias or inhalation-related adverse events requiring discontinuation. Nebulized milrinone produced serum concentrations in the goal therapeutic range with a median plasma milrinone trough concentration of 39 (17-66) ng/mL and a median peak concentration of 207 (134-293) ng/mL. There were no serious adverse events. From baseline to 24 hours, mean pulmonary artery saturation increased (60% ± 7%-65 ± 5%; P = 0.001), and mean cardiac index increased (2.0 ± 0.5 mL/min/1.73m2-2.5 ± 0.1 mL/min/1.73m2; P = 0.001) with nebulized milrinone. CONCLUSIONS In a proof-of-concept study, a concentrated, nebulized milrinone formulation for inhalation was safe and produced therapeutic serum milrinone concentrations. Nebulized milrinone was associated with improved hemodynamic parameters of cardiac output in a population with advanced HF. These promising results require further investigation in a longer-term trial in patients with inotrope-dependent advanced HF.

Abstract
Use of continuous intravenous inotropic support (CIIS) strictly as palliative therapy for patients with ACC/AHA Stage D (end-stage) Heart Failure (HF) has increased significantly. The harms of CIIS therapy may detract from its benefits. To describe benefits (improvement in NYHA functional class) and harms (infection, hospitalization, days-spent-in-hospital) of CIIS as palliative therapy. Methods: Retrospective analysis of patients with end-stage HF initiated on CIIS as palliative therapy at an urban, academic center in the United States between 2014-2016. Clinical outcomes were extracted, and data were analyzed using descriptive statistics. Seventy-five patients, 72% male, 69% African American/Black, with a mean age 64.5 years (SD = 14.5) met study criteria. Mean duration of CIIS was 6.5 months (SD = 7.7). Most patients (69.3%) experienced improvement in NYHA functional class from class IV to class III. Sixty-seven patients (89.3%) were hospitalized during their time on CIIS, with a mean of 2.7 hospitalizations per patient (SD = 3.3). One-third of patients (n = 25) required at least one intensive care unit (ICU) admission while on CIIS therapy. Eleven patients (14.7%) experienced catheter-related blood stream infection. Patients spent an average of 20.6% (SD = 22.8), approximately 40 days, of their time on CIIS admitted to the study institution. Patients on CIIS as palliative therapy report improvement in functional class, survive 6.5 months following initiation, but spend a significant number of days in the hospital. Prospective studies quantifying the symptomatic benefit and the direct and indirect harms of CIIS as palliative therapy are warranted.

[PMID: 37908500 PMCID: PMC10613676 DOI: 10.3389/fcvm.2023.1183504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Accepted: 09/19/2023] [Indexed: 11/02/2023] Open
Abstract
Background and objective Cardiovascular disease is the leading cause of morbidity and mortality globally. Echocardiography is a commonly used method for assessing the condition of patients with cardiovascular disease. However, little is known about the population characteristics of patients who are recommended for echocardiographic examinations. Methods The National Ambulatory Medical Care Survey was a cross-sectional survey previously undertaken in the USA. In this study, publicly accessible data from the National Ambulatory Medical Care Survey database (for 2007-2016 and 2018-2019; data for 2017 was not published) were utilized to create a nomogram based on significant risk predictors. The study was performed in accordance with the relevant guidelines and regulations stipulated in the National Ambulatory Medical Care Survey database. Patients were randomly assigned to one of two groups: training cohort or validation cohort. The latter was used to assess the reliability of the prediction nomogram. Decision curve analysis was performed to evaluate the net benefit. Propensity score matching analysis was used to evaluate the relevance of echocardiography to clinical decision-making. Results A total of 217,178 outpatients were enrolled. Multivariable logistic regression analysis demonstrated that hypertension, hyperlipidemia, coronary artery disease/ischemic heart disease/history of myocardial infarction, congestive heart failure, major reason for visit, metropolitan statistical area, cerebrovascular disease/history of stroke or transient ischemic attack, previously assessed, insurance, referred, diagnosis, and reason for visit were all predictors of echocardiogram prescription in outpatients. The reliability of the predictive nomogram was confirmed in the validation cohort. After propensity score matching, there was a significant difference in new cardiovascular agent prescriptions between the echocardiogram and no echocardiogram groups (P < 0.01). Conclusion In this cohort study, a nomogram based on the characteristics of outpatients was developed to predict the possibility of prescribing echocardiography. The echocardiogram group was more likely to be prescribed new cardiovascular agents. These findings may contribute to providing information about the gap between actual utilizations and guidelines and the actual outpatient practice, as well as meeting the needs of outpatients.

Am J Cardiol 2022; 184:80-89. [PMID: 36167736 DOI: 10.1016/j.amjcard.2022.08.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 07/14/2022] [Accepted: 08/17/2022] [Indexed: 11/01/2022]
Abstract
This study aims to determine the incidence of all-cause hospitalization in patients with advanced heart failure (AHF) receiving ambulatory continuous, intravenous dobutamine versus milrinone for palliative intent. Despite medical optimization, patients with AHF develop refractory symptoms, resulting in frequent hospitalizations. Previous trials precede modern care standards. Data regarding inotrope choice in palliation are limited. This retrospective analysis included 222 patients with AHF and reduced left ventricular ejection fraction discharged on palliative dobutamine (n = 135) or milrinone (n = 87). The primary outcome was incidence of all-cause rehospitalization compared by treatment type. Demographics between groups were similar. In the milrinone arm, more patients were discharged on β blockers (62% vs 22%; p <0.001); fewer patients were discharged to hospice (6% vs 30%). More patients in the milrinone arm than in the dobutamine arm were rehospitalized within 180 days (80% vs 59%; p = 0.002); when patients discharged to hospice were excluded, this difference was no longer significant (83% vs 74%; p = 0.14). Overall mortality was lower in the milrinone arm (63% vs 80%; p = 0.006); survival was longer (median: 228 vs 52 days; p <0.001). Patients receiving milrinone spent more days alive and out of the hospital at 90 days after discharge (70 vs 37 days; p <0.001). In conclusion, in patients with AHF receiving palliative inotropes, there was no difference in rehospitalization when excluding patients discharged to hospice. Milrinone use was associated with decreased mortality and longer survival. Agent selection must closely align with the patient's disease trajectory.

Abstract
BACKGROUND Continuous infusion of ambulatory inotropic therapy (AIT) is increasingly used in patients with end-stage heart failure (HF). There is a paucity of data concerning the concomitant use of beta-blockers (BB) in these patients. METHODS We retrospectively reviewed all patients discharged from our institution on AIT. The cohort was stratified into 2 groups based on BB use. The 2 groups were compared for differences in hospitalizations due to HF, ventricular arrhythmias and ICD therapies (shock or antitachycardia pacing). RESULTS Between 2010 and 2017, 349 patients were discharged on AIT (95% on milrinone); 74% were males with a mean age of 61 ± 14 years. BB were used in 195 (56%) patients, whereas 154 (44%) did not receive these medications. Patients in the BB group had longer duration of AIT support compared to those in the non-BB group (141 [1-2114] vs 68 [1-690] days). After adjusting for differences in baseline characteristics and indication for AIT, patients in the BB group had significantly lower rates of hospitalizations due to HF (hazard ratio [HR] 0.61 (0.43-0.86); P = 0.005), ventricular arrhythmias (HR 0.34 [0.15-0.74]; P = 0.007) and ICD therapies (HR 0.24 [0.07-0.79]; P = 0.02). CONCLUSION In patients with end-stage HF on AIT, the use of BB with inotropes was associated with fewer hospitalizations due to HF and fewer ventricular arrhythmias.
