Effects of remote haemodynamic-guided heart failure management in patients with different subtypes of pulmonary hypertension: insights from the MEMS-HF study.

AIM: The CardioMEMS European Monitoring Study for Heart Failure (MEMS-HF) investigated safety and efficacy of pulmonary artery pressure (PAP)-guided remote patient management (RPM) in New York Heart Association (NYHA) class III outpatients with at least one heart failure hospitalization (HFH) during the previous 12 months. This pre-specified subgroup analysis investigated whether RPM effects depended on presence and subtype of pulmonary hypertension (PH). METHODS AND RESULTS: In 106/234 MEMS-HF participants, Swan-Ganz catheter tracings obtained during sensor implant were available for off-line manual analysis jointly performed by two experts. Patients were classified into subgroups according to current PH definitions. Isolated post-capillary PH (IpcPH) and combined post- and pre-capillary PH (CpcPH) were present in 38 and 36 patients, respectively, whereas 31 patients had no PH. Clinical characteristics were comparable between subgroups, but among patients with PH pulmonary vascular resistance was higher (p = 0.029) and pulmonary artery compliance lower (p = 0.003) in patients with CpcPH. During 12 months of PAP-guided RPM, all PAPs declined in IpcPH and CpcPH subgroups (all p < 0.05), whereas only mean and diastolic PAP decreased in patients without PH (both p < 0.05). Improvements in post- versus pre-implant HFH rates were similar in CpcPH (0.639 events/patient-year; hazard ratio [HR] 0.37) and IpcPH (0.72 events/patient-year; HR 0.45) patients. Participants without PH benefited most (0.26 events/patient-year; HR 0.17, p = 0.04 vs. IpcPH/CpcPH patients). Quality of life and NYHA class improved significantly in all subgroups. CONCLUSIONS: Outpatients with NYHA class III symptoms with at least one HFH during 1 year pre-implant benefitted significantly from PAP-guided RPM during post-implant follow-up irrespective of presence or subtype of PH at baseline.

Efficacy of Plinabulin vs Pegfilgrastim for Prevention of Docetaxel-Induced Neutropenia in Patients With Solid Tumors: A Randomized Clinical Trial.

Importance: Prevention of chemotherapy-induced neutropenia (CIN) and its clinical consequences is an unmet need for which plinabulin, a selective immunomodulating microtubule-binding agent, is being tested. Objective: To demonstrate noninferiority between plinabulin and pegfilgrastim for days of severe neutropenia in cycle 1 in patients with solid tumors treated with docetaxel. Design, Setting, and Participants: The Plinabulin vs Pegfilgrastim for the Prevention of Docetaxel-Induced Neutropenia in Patients With Solid Tumors (PROTECTIVE-1) double-blind phase 3 randomized clinical trial was performed in multiple centers in China, Russia, Ukraine, and the US. Participants included patients with breast, prostate, or non-small cell lung cancer treated with single-agent docetaxel chemotherapy. Data were collected from June 1, 2018, to January 31, 2019. The database was locked on February 18, 2021. Data analysis was based on intention to treat and safety and performed from October 5, 2018, to February 23, 2021. Interventions: Plinabulin, 40 mg, plus placebo or pegfilgrastim, 6 mg, plus placebo. Main Outcomes and Measures: The primary end point was day of severe neutropenia in cycle 1. Additional end points included clinical consequences of CIN (febrile neutropenia, hospitalizations, infections, antibiotic use, and modifications of chemotherapy dose), patient-reported outcomes for bone pain score, markers for immune suppression (neutrophil-to-lymphocyte ratio [NLR] of >5), immature neutrophils (band, promyelocyte, and myelocyte counts >0), and safety. Results: Among the 105 patients included in the analysis (65 [6.19%] women; median age, 59 [range, 31-81] years), the primary end point was met within a noninferiority margin of 0.65 days, with a mean difference of 0.52 days (98.52% CI, 0.40-0.65 days). Grade 4 neutropenia frequency in cycle 1 was not significantly different. Plinabulin had earlier onset of action with less grade 4 neutropenia in week 1 of cycle 1. Plinabulin had fewer adverse clinical consequences with rates of febrile neutropenia (0 of 52 vs 1 of 53 [1.9%]), infections (4 of 52 [7.7%] vs 8 of 53 [15.1%]), chemotherapy dose delay of more than 7 days (2 of 52 [3.8%] vs 3 of 53 [5.7%]), and permanent chemotherapy discontinuation (7 of 52 [13.5%] vs 14 of 53 [26.4%]). Patients receiving plinabulin had significantly less bone pain (difference, -0.67 [95% CI, -1.17 to -0.16]; P = .01) and a better immunosuppressive profile (NLR >5 at day 8, 2 of 52 [3.8%] vs 24 of 51 [46.0%]; P < .001). Plinabulin was well tolerated, with comparable safety to pegfilgrastim. Conclusions and Relevance: Plinabulin has comparable efficacy to pegfilgrastim for the prevention of CIN, with better safety and a better immunosuppressive profile. Plinabulin's same-day dosing compared with pegfilgrastim's next-day dosing offers distinct advantages, including reducing use of health care services.

Haemodynamic-guided management of heart failure (GUIDE-HF): a randomised controlled trial.

BACKGROUND: Previous studies have suggested that haemodynamic-guided management using an implantable pulmonary artery pressure monitor reduces heart failure hospitalisations in patients with moderately symptomatic (New York Heart Association [NYHA] functional class III) chronic heart failure and a hospitalisation in the past year, irrespective of ejection fraction. It is unclear if these benefits extend to patients with mild (NYHA functional class II) or severe (NYHA functional class IV) symptoms of heart failure or to patients with elevated natriuretic peptides without a recent heart failure hospitalisation. This trial was designed to evaluate whether haemodynamic-guided management using remote pulmonary artery pressure monitoring could reduce heart failure events and mortality in patients with heart failure across the spectrum of symptom severity (NYHA funational class II-IV), including those with elevated natriuretic peptides but without a recent heart failure hospitalisation. METHODS: The randomised arm of the haemodynamic-GUIDEed management of Heart Failure (GUIDE-HF) trial was a multicentre, single-blind study at 118 centres in the USA and Canada. Following successful implantation of a pulmonary artery pressure monitor, patients with all ejection fractions, NYHA functional class II-IV chronic heart failure, and either a recent heart failure hospitalisation or elevated natriuretic peptides (based on a-priori thresholds) were randomly assigned (1:1) to either haemodynamic-guided heart failure management based on pulmonary artery pressure or a usual care control group. Patients were masked to their study group assignment. Investigators were aware of treatment assignment but did not have access to pulmonary artery pressure data for control patients. The primary endpoint was a composite of all-cause mortality and total heart failure events (heart failure hospitalisations and urgent heart failure hospital visits) at 12 months assessed in all randomly assigned patients. Safety was assessed in all patients. A pre-COVID-19 impact analysis for the primary and secondary outcomes was prespecified. This study is registered with ClinicalTrials.gov, NCT03387813. FINDINGS: Between March 15, 2018, and Dec 20, 2019, 1022 patients were enrolled, with 1000 patients implanted successfully, and follow-up was completed on Jan 8, 2021. There were 253 primary endpoint events (0·563 per patient-year) among 497 patients in the haemodynamic-guided management group (treatment group) and 289 (0·640 per patient-year) in 503 patients in the control group (hazard ratio [HR] 0·88, 95% CI 0·74-1·05; p=0·16). A prespecified COVID-19 sensitivity analysis using a time-dependent variable to compare events before COVID-19 and during the pandemic suggested a treatment interaction (pinteraction=0·11) due to a change in the primary endpoint event rate during the pandemic phase of the trial, warranting a pre-COVID-19 impact analysis. In the pre-COVID-19 impact analysis, there were 177 primary events (0·553 per patient-year) in the intervention group and 224 events (0·682 per patient-year) in the control group (HR 0·81, 95% CI 0·66-1·00; p=0·049). This difference in primary events almost disappeared during COVID-19, with a 21% decrease in the control group (0·536 per patient-year) relative to pre-COVID-19, virtually no change in the treatment group (0·597 per patient-year), and no difference between groups (HR 1·11, 95% CI 0·80-1·55; p=0·53). The cumulative incidence of heart failure events was not reduced by haemodynamic-guided management (0·85, 0·70-1·03; p=0·096) in the overall study analysis but was significantly decreased in the pre-COVID-19 impact analysis (0·76, 0·61-0·95; p=0·014). 1014 (99%) of 1022 patients had freedom from device or system-related complications. INTERPRETATION: Haemodynamic-guided management of heart failure did not result in a lower composite endpoint rate of mortality and total heart failure events compared with the control group in the overall study analysis. However, a pre-COVID-19 impact analysis indicated a possible benefit of haemodynamic-guided management on the primary outcome in the pre-COVID-19 period, primarily driven by a lower heart failure hospitalisation rate compared with the control group.

Pulmonary Artery Proportional Pulse Pressure (PAPP) Index Identifies Patients With Improved Survival From the CardioMEMS Implantable Pulmonary Artery Pressure Monitor.

BACKGROUND: Pulmonary artery proportional pulse pressure (PAPP) was recently shown to have prognostic value in heart failure (HF) with reduced ejection fraction (HFrEF) and pulmonary hypertension. We tested the hypothesis that PAPP would be predictive of adverse outcomes in patients with implantable pulmonary artery pressure monitor (CardioMEMS™ HF System, St. Jude Medical [now Abbott], Atlanta, GA, USA). METHODS: Survival analysis with Cox proportional hazards regression was used to evaluate all-cause deaths and HF hospitalisation (HFH) in CHAMPION trial1 patients who received treatment with the CardioMEMS device based on the PAPP. RESULTS: Among 550 randomised patients, 274 had PAPP ≤ the median value of 0.583 while 276 had PAPP>0.583. Patients with PAPP≤0.583 (versus PAPP>0.583) had an increased risk of HFH (HR 1.40, 95% CI 1.16-1.68, p=0.0004) and experienced a significant 46% reduction in annualised risk of death with CardioMEMS treatment (HR 0.54, 95% CI 0.31-0.92) during 2-3 years of follow-up. This survival benefit was attributable to the treatment benefit in patients with HFrEF and PAPP≤0.583 (HR 0.50, 95% CI 0.28-0.90, p<0.05). Patients with PAPP>0.583 or HF with preserved EF (HFpEF) had no significant survival benefit with treatment (p>0.05). CONCLUSION: Lower PAPP in HFrEF patients with CardioMEMS constitutes a higher mortality risk status. More studies are needed to understand clinical applications of PAPP in implantable pulmonary artery pressure monitors.

Remote Hemodynamic-Guided Therapy of Patients With Recurrent Heart Failure Following Cardiac Resynchronization Therapy.

Background Patients with recurring heart failure (HF) following cardiac resynchronization therapy fare poorly. Their management is undecided. We tested remote hemodynamic-guided pharmacotherapy. Methods and Results We evaluated cardiac resynchronization therapy subjects included in the CHAMPION (CardioMEMS Heart Sensor Allows Monitoring of Pressure to Improve Outcomes in New York Heart Association Class III Heart Failure Patients) trial, which randomized patients with persistent New York Heart Association Class III symptoms and ≥1 HF hospitalization in the previous 12 months to remotely managed pulmonary artery (PA) pressure-guided management (treatment) or usual HF care (control). Diuretics and/or vasodilators were adjusted conventionally in control and included remote PA pressure information in treatment. Annualized HF hospitalization rates, changes in PA pressures over time (analyzed by area under the curve), changes in medications, and quality of life (Minnesota Living with Heart Failure Questionnaire scores) were assessed. Patients who had cardiac resynchronization therapy (n=190, median implant duration 755 days) at enrollment had poor hemodynamic function (cardiac index 2.00±0.59 L/min per m2), high comorbidity burden (67% had secondary pulmonary hypertension, 61% had estimated glomerular filtration rate <60 mL/min per 1.73 m2), and poor Minnesota Living with Heart Failure Questionnaire scores (57±24). During 18 months randomized follow-up, HF hospitalizations were 30% lower in treatment (n=91, 62 events, 0.46 events/patient-year) versus control patients (n=99, 93 events, 0.68 events/patient-year) (hazard ratio, 0.70; 95% CI, 0.51-0.96; P=0.028). Treatment patients had more medication up-/down-titrations (847 versus 346 in control, P<0.001), mean PA pressure reduction (area under the curve -413.2±123.5 versus 60.1±88.0 in control, P=0.002), and quality of life improvement (Minnesota Living with Heart Failure Questionnaire decreased -13.5±23 versus -4.9±24.8 in control, P=0.006). Conclusions Remote hemodynamic-guided adjustment of medical therapies decreased PA pressures and the burden of HF symptoms and hospitalizations in patients with recurring Class III HF and hospitalizations, beyond the effect of cardiac resynchronization therapy.

Incorporating Pharmacist Interns Into a Study of Fall-Risks.

INTRODUCTION: Inpatient falls continue to have detrimental effects on patient care and recovery. Because controllable and uncontrollable factors impact fall rates, predicting which patients are at the greatest risk can be challenging. One method includes the incorporation of student learners to help identify which patients are at the greatest risk for falls.
OBJECTIVE: To generate a scoring metric and investigate its reliability for appropriately identifying geriatric and medical psychiatric patients at risk for falling while hospitalized.
METHODS: In this single-center, quasi-experimental study, pharmacist-interns led a fall-prevention initiative at a community hospital within two behavioral health units.
RESULTS: A total of 96 patients were analyzed over the study period, revealing no notable trends for either geriatric or medical psychiatric patients. There was no significant change in the odds of falling for each fall score point increase for either the geriatric-psychiatric unit (odds ratio [OR] = 0.95; 95% confidence interval [CI] 0.83-1.08) or the medical-psychiatric unit (OR = 1.11; 95% CI 0.91-1.36).
CONCLUSION: This pharmacist-intern-led falls-prevention initiative did not provide a statistically significant reduction in falls. While the scoring metric was helpful in reviewing charts to make recommendations for interventions, the assigned score did not correlate as expected to incidents of falls.

Pulmonary artery pressure-guided therapy in ambulatory patients with symptomatic heart failure: the CardioMEMS European Monitoring Study for Heart Failure (MEMS-HF).

AIMS: Heart failure (HF) leads to repeat hospitalisations and reduces the duration and quality of life. Pulmonary artery pressure (PAP)-guided HF management using the CardioMEMS™ HF system was shown to be safe and reduce HF hospitalisation (HFH) rates in New York Heart Association (NYHA) class III patients. However, these findings have not been replicated in health systems outside the United States. Therefore, the CardioMEMS European Monitoring Study for Heart Failure (MEMS-HF) evaluated the safety, feasibility, and performance of this device in Germany, The Netherlands, and Ireland. METHODS AND RESULTS: A total of 234 NYHA class III patients (68 ± 11 years, 22% female, ≥1 HFH in the preceding year) from 31 centres were implanted with a CardioMEMS sensor and underwent PAP-guided HF management. One-year rates of freedom from device- or system-related complications and from sensor failure (co-primary outcomes) were 98.3% [95% confidence interval (CI) 95.8-100.0] and 99.6% (95% CI 97.6-100.0), respectively. Survival rate was 86.2%. For the 12 months post- vs. pre-implant, HFHs decreased by 62% (0.60 vs. 1.55 events/patient-year; hazard ratio 0.38, 95% CI 0.31-0.48; P < 0.0001). After 12 months, mean PAP decreased by 5.1 ± 7.4 mmHg, Kansas City Cardiomyopathy Questionnaire (KCCQ) overall/clinical summary scores increased from 47.0 ± 24.0/51.2 ± 24.8 to 60.5 ± 24.3/62.4 ± 24.1 (P < 0.0001), and the 9-item Patient Health Questionnaire sum score improved from 8.7 ± 5.9 to 6.3 ± 5.1 (P < 0.0001). CONCLUSION: Haemodynamic-guided HF management proved feasible and safe in the health systems of Germany, The Netherlands, and Ireland. Physician-directed treatment modifications based on remotely obtained PAP values were associated with fewer HFH, sustainable PAP decreases, marked KCCQ improvements, and remission of depressive symptoms.

A global registry of fractional flow reserve (FFR)-guided management during routine care: Study design, baseline characteristics and outcomes of invasive management.

BACKGROUND: The use and clinical outcomes of fractional flow reserve (FFR)-guided revascularization in patients presenting with either stable coronary artery disease (CAD) or an acute coronary syndrome (ACS) in daily clinical practice are uncertain. OBJECTIVE: To prospectively characterize the frequency of the change in treatment plan when FFR is performed compared to the initial decision based on angiography alone and procedure-related outcomes. METHODS: We undertook a prospective, multicenter, multinational, open-label, observational study of coronary physiologic measurements during clinically indicated coronary angiography. The treatment plan, including medical therapy, PCI or CABG, was prospectively recorded before and after performing FFR. Adverse events were pre-defined and prospectively recorded per local investigators (PRESSUREwire; ClinicalTrials.gov identifier: NCT02935088). RESULTS: Two thousand two hundred and seventeen subjects were enrolled in 70 hospitals across 15 countries between October 2016-February 2018. The mean FFR (all measurements) was 0.84. The treatment plan based on angiography-alone changed in 763/2196 subjects (34.7%) and 872/2931 lesions (29.8%) post-FFR. In the per-patient analysis, the initial treatment plan based on angiography versus the final treatment plan post-FFR were medical management 1,350 (61.5%) versus 1,470 (66.9%) (p = .0017); PCI 717 (32.7%) versus 604 (27.5%) (p = .0004); CABG 119 (5.4%) versus 121 (5.5%) (p = .8951). The frequency of intended revascularization changed from 38.1 to 33.0% per patient (p = .0005) and from 35.5 to 29.6% per lesion (p < .0001) following FFR. CONCLUSIONS: On an individual patient basis, use of FFR in everyday practice changes the treatment plan compared to angiography in more than one third of all-comers selected for physiology-guided managements. FFR measurement is safe, providing incremental information to guide revascularization decisions.

Monitoring Pulmonary Arterial Hypertension Using an Implantable Hemodynamic Sensor.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a chronic disease that ultimately progresses to right-sided heart failure (HF) and death. Close monitoring of pulmonary artery pressure (PAP) and right ventricular (RV) function allows clinicians to appropriately guide therapy. However, the burden of commonly used methods to assess RV hemodynamics, such as right heart catheterization, precludes frequent monitoring. The CardioMEMS HF System (Abbott) is an ambulatory implantable hemodynamic monitor, previously only used in patients with New York Heart Association (NYHA) class III HF. In this study, we evaluate the feasibility and early safety of monitoring patients with PAH and right-sided HF using the CardioMEMS HF System. METHODS: The CardioMEMS HF sensors were implanted in 26 patients with PAH with NYHA class III or IV right-sided HF (51.3 ± 18.3 years of age, 92% women, 81% NYHA class III). PAH therapy was tracked using a minimum of weekly reviews of CardioMEMS HF daily hemodynamic measurements. Safety, functional response, and hemodynamic response were tracked up to 4 years with in-clinic follow-ups. RESULTS: The CardioMEMS HF System was safely used to monitor PAH therapy, with no device-related serious adverse events observed and a single preimplant serious adverse event. Significant PAP reduction and cardiac output elevation were observed as early as 1 month postimplant using trends of CardioMEMS HF data, coupled with significant NYHA class and quality of life improvements within 1 year. CONCLUSIONS: The CardioMEMS HF System provided useful information to monitor PAH therapy, and demonstrated short- and long-term safety. Larger clinical trials are needed before its widespread use to guide therapy in patients with severe PAH with right-sided HF.

Remote haemodynamic-guided care for patients with chronic heart failure: a meta-analysis of completed trials.

AIMS: Haemodynamic-guided heart failure (HF) management using directly measured cardiac filling pressures in symptomatic patients is now recommended in the European Society of Cardiology (ESC) Heart Failure Guidelines [Class IIb(B)]. This meta-analysis evaluates all data from completed clinical trials evaluating this approach in patients with HF. METHODS AND RESULTS: All trials evaluating the impact of HF management based on haemodynamic monitoring using implantable devices were reviewed using standard search engine methods. PRISMA methods were used to evaluate and screen publications that included an evaluation of an effect on HF hospitalizations. All publications meeting the inclusion criteria were included, and the outcomes data were evaluated using standard meta-analysis methodology. Of 317 publications initially identified, five trials involving 1296 patients with chronic HF met the criteria used in this meta-analysis. Studies included prospective controlled designs, as well as observational studies with historical control. Heterogeneity testing failed to demonstrate instability of analysis due to differences between trials. When compiled, outcomes from these trials favoured remote haemodynamic monitoring with a significant 38% reduction in HF hospitalizations (hazard ratio 0.62, 95% confidence interval 0.50-0.78, P < 0.001). CONCLUSIONS: Haemodynamic-guided HF management using permanently implanted sensors and frequent filling pressure evaluation is superior to traditional clinical management strategies in reducing long-term HF hospitalization risk in symptomatic patients.

Heart failure and respiratory hospitalizations are reduced in patients with heart failure and chronic obstructive pulmonary disease with the use of an implantable pulmonary artery pressure monitoring device.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a frequent comorbidity in patients with heart failure (HF). Elevated pulmonary arterial (PA) pressure can be seen in both conditions and has been shown to predict morbidity and mortality. METHODS AND RESULTS: A total of 550 subjects with New York Heart Association functional class III HF were randomly assigned to the treatment (n = 270) and control (n = 280) groups in the CHAMPION Trial. Physicians had access to the PA pressure measurements in the treatment group only, in which HF therapy was used to lower the elevated pressures. HF and respiratory hospitalizations were compared in both groups. A total of 187 subjects met criteria for classification into the COPD subgroup. In the entire cohort, the treatment group had a 37% reduction in HF hospitalization rates (P < .0001) and a 49% reduction in respiratory hospitalization rates (P = .0061). In the COPD subgroup, the treatment group had a 41% reduction in HF hospitalization rates (P = .0009) and a 62% reduction in respiratory hospitalization rates (P = .0023). The rate of respiratory hospitalizations in subjects without COPD was not statistically different (P = .76). CONCLUSIONS: HF management incorporating hemodynamic information from an implantable PA pressure monitor significantly reduces HF and respiratory hospitalizations in HF subjects with comorbid COPD compared with standard care.
