Remote monitoring in chronic heart failure patients: Is non-invasive remote monitoring the way to go?

Heart failure (HF) is a major health care issue, and the incidence of HF is only expected to grow further. Due to the frequent hospitalizations, HF places a major burden on the available hospital and healthcare resources. In the future, HF care should not only be organized solely at the clinical ward and outpatient clinics, but remote monitoring strategies are urgently needed to guide, monitor, and treat chronic HF patients remotely from their homes as well. The intuitiveness and relatively low costs of non-invasi

Two decades after coronary radiation therapy: A single center longitudinal clinical study

Objectives: The aim of this study was to evaluate the very long-term clinical outcome after radioactive stent (RS) implantation and intracoronary β radiation brachytherapy (IRBT). Background: Radioactive stents (RS) and intracoronary β radiation brachytherapy (IRBT) were introduced to prevent restenosis after percutaneous coronary intervention (PCI). Both techniques were associated with a higher incidence of major adverse cardiac events (MACE) in the short and intermediate-term follow up as compared to conventional PCI. Methods: One hundred and thirty-three patients received radioactive stents (32P) and 301 patients were treated with IRBT adjunctive to PCI. These groups were propensity matched to respectively 266 and 602 control patients who were treated with routine PCI during the same inclusion period. Endpoints were all-cause mortality and MACE, defined as all-cause death, any myocardial infarction or any revascularization. Results: Median follow-up duration was 17 years. All-cause mortality rates were similar in all groups. Adjusted hazard ratios for MACE and mortality in the RS cohort were 1.55 (95% CI 1.20–2.00) and 0.92 (95% CI 0.63–1.34), respectively. Adjusted hazard ratios for MACE and all-cause mortality in the IRBT cohort were 1.41 (95% CI 1.18–1.67) and 0.95 (95% CI 0.74–1.21), respectively. The difference in MACE rates was predominantly driven by coronary revascularizations in both groups, with a higher MI rate in the IRBT group as well. Conclusions: Coronary radiation therapy was associated with early increased MACE rates, but the difference in MACE rates decreased beyond 2 years, resulting in a comparable long-term clinical outcome. Importantly, no excess in mortality was observed

A randomised comparison of the effect of haemodynamic monitoring with CardioMEMS in addition to standard care on quality of life and hospitalisations in patients with chronic heart failure: Design and rationale of the MONITOR HF multicentre randomised clinical trial

Background: Assessing haemodynamic congestion based on filling pressures instead of clinical congestion can be a way to further improve quality of life (QoL) and clinical outcome by intervening before symptoms or weight gain occur in heart failure (HF) patients. The clinical efficacy of remote monitoring of pulmonary artery (PA) pressures (CardioMEMS; Abbott Inc., Atlanta, GA, USA) has been demonstrated in the USA. Currently, the PA sensor is not reimbursed in the European Union as its benefit when applied in addition to standard HF care is unknown in Western European countries, including the Netherlands. Aims: To demonstrate the efficacy and cost-effectiveness of haemodynamic PA monitoring in addition to contemporary standard HF care in a high-quality Western European health care system. Methods: The current study is a prospective, multi-centre, randomised clinical trial in 340 patients with chronic HF (New York Heart Association functional class III) randomised to HF care including remote monitoring with the CardioMEMS PA sensor or standard HF care alone. Eligible patients have at least one hospitalisation for HF in 12 months before enrolment and will be randomised in a 1:1 ratio. Minimum follow-up will be 1 year. The primary endpoint is the change in QoL as measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ). Secondary endpoints are the number of HF hospital admissions and changes in health status assessed by EQ-5D-5L questionnaire including healt

Remote monitoring of heart failure in patients with implantable cardioverter-defibrillators

The management of heart failure remains challenging despite evidence-based medical and pharmacological advances, especially in the ambulatory setting. There is an urgent need to develop strategies to reduce hospitalizations and readmission rates due to heart failure. Frequent monitoring of high-risk patients is imperative, and with the development of wireless and remote technology, frequent monitoring is now possible via remote monitoring. Nowadays, remote management of patients with cardiac implantable electronic devices is being increasingly adopted and integrated into clinical practice. Several clinical trials studied the impact of remote monitoring on clinical outcomes in patients with implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization defibrillators (CRT-Ds). This point of view will focus on the remote monitoring of ICDs and CRTDs in patients with heart failure and discusses whether remote monitoring can be used as a potential instrument for the early identification of patients at risk

Safety and feasibility of hemodynamic pulmonary artery pressure monitoring using the CardioMEMS device in LVAD management

Background: There is a clinical need for additional remote tools to improve left ventricular assist device (LVAD) patient management. The aim of this pilot concept study was to assess the safety and feasibility of optimizing patient management with add-on remote hemodynamic monitoring using the CardioMEMS in LVAD patients during different treatment stages. Methods: Ten consecutive patients accepted and clinically ready for (semi-) elective HeartMate 3 LVAD surgery were included. All patients received a CardioMEMS to optimize filling pressure before surgery. Patients were categorized into those with normal mean pulmonary artery pressure (mPAP) (≤25 mmHg, n = 4) or elevated mPAP (&gt;25 mmHg, n = 6), and compared to a historical cohort (n = 20). Endpoints were CardioMEMS device safety and a combined endpoint of all-cause mortality, acute kidney injury, renal replacement therapy and/or right ventricular failure at 1-year follow-up. Additionally, we investigated hospital-free survival and improvement in quality of life (QoL) and exercise tolerance. Results: No safety issues or signal interferences were observed. The combined endpoint occurred in 60% of historical controls, 0% in normal and 83% in elevated mPAP group. Post-discharge, the hospital-free survival was significantly better, and the QoL improved more in the normal compared to the elevated mPAP group. Conclusion: Remote hemodynamic monitoring in LVAD patients is safe and feasible with the CardioMEMS, which could be used to identify patients at elevated risk of complications as well as optimize patient management remotely during the out-patient phase with less frequent hospitalizations. Larger pivotal studies are warranted to test the hypothesis generated from this concept study.</p
