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, multicentre, 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 health care utilisation and formal cost-effectiveness analysis. Conclusion The MONITOR HF trial will evaluate the efficacy and cost-effectiveness of haemodynamic monitoring by CardioMEMS in addition to standard HF care in patients with chronic HF. Clinical Trial Registration number NTR7672.

BackgroundIn patients with myocardial infarction or heart failure, right ventricular (RV) dysfunction is associated with death, shock and arrhythmias. In patients with type 2 diabetes mellitus, structural and functional alterations of the left ventricle (LV) are highly prevalent, however, little is known about the impact of diabetes on RV characteristics. The purpose of the present study was to investigate whether LV changes are paralleled by RV alterations in a rat model of diabetes.MethodsZucker diabetic fatty (ZDF) and control (ZL) rats underwent echocardiography and positron emission tomography (PET) scanning using [18F]-2-fluoro-2-deoxy-D-glucose under hyperinsulinaemic euglycaemic clamp conditions. Glucose, insulin, triglycerides and fatty acids were assessed from trunk blood. Another group of rats received an insulin or saline injection to study RV insulin signaling.ResultsZDF rats developed hyperglycaemia, hyperinsulinaemia and dyslipidaemia (all p < 0.05). Echocardiography revealed depressed LV fractional shortening and tricuspid annular plane systolic excursion (TAPSE) in ZDF vs. ZL rats (both p < 0.05). A decrease in LV and RV insulin-mediated glucose utilisation was found in ZDF vs. ZL rats (both p < 0.05). LV associated with RV with respect to systolic function (r = 0.86, p < 0.05) and glucose utilisation (r = 0.74, p < 0.05). TAPSE associated with RV MRglu (r = 0.92, p < 0.05) and M-value (r = 0.91, p < 0.0001) and RV MRglu associated with M-value (r = 0.77, p < 0.05). Finally, reduced RV insulin-stimulated phosphorylation of Akt was found in ZDF vs. ZL (p < 0.05).ConclusionsLV changes were paralleled by RV alterations in insulin-stimulated glucose utilisation and RV systolic function in a rat model of diabetes, which may be attributed to ventricular interdependence as well as to the uniform effect of diabetes. Since diabetic patients are prone to develop diabetic cardiomyopathy and myocardial ischaemia, it might be suggested that RV dysfunction plays a central role in cardiac abnormalities in this population.

AimsThis study aims to assess the presence of geriatric domain impairments in an older heart failure (HF) outpatient population and to relate these domain impairments with 1 year mortality risk in comparison with a geriatric outpatient population without HF. Methods and results Data were used from two different prospective cohort studies: 241 outpatients with HF (mean age 78 ± 9 years, 48% female) and 686 geriatric outpatients (mean age 80 ± 7 years, 55% female). We similarly assessed the following geriatric domains in both cohorts: physical function, nutritional status, polypharmacy, cognitive function, and activities in daily living. Cox proportional hazards analyses were used to relate individual domains to 1 year mortality risk in both populations and to compare 1 year mortality risk between both populations. Of the patients with HF, 34% had impairments in ≥3 domains, compared with 38% in geriatric patients. One-year mortality rates were 13% and 8%, respectively, in the HF and geriatric populations; age-adjusted and sex-adjusted hazard ratio (95% confidence interval) for patients with HF compared with geriatric patients was 1.7 (1.3-2.6). The individual geriatric domains were similarly associated with 1 year mortality risk in both populations. Compared with zero to two impaired domains, age-adjusted and sex-adjusted mortality risk (hazard ratio, 95% confidence interval) for three, four, or five impaired domains ranged from 1.6 (0.6-4.2) to 6.5 (2.1-20.1) in the HF population and from 1.4 (0.7-2.9) to 7.9 (2.9-21.3) in the geriatric population. Conclusions In parallel with geriatric patients, patients with HF often have multiple geriatric domain impairments that adversely affect their prognosis. This similarity together with the findings that patients with HF have a higher 1 year mortality risk than a general geriatric population supports the integration of a multi-domain geriatric assessment in outpatient HF care.
