Heart Failure Decompensation

Abstract Background Heart failure decompensation requiring hospitalization is an important event, associated with mortality and investigating its predictors is topical problem. Chronic obstructive pulmonary disease (COPD) is a common comorbidity for heart failure. Both conditions share common molecular mechanisms such as systemic inflammation. COPD is heterogeneous and subpopulations with different inflammation patterns may interact with heart failure in different manner. Airway inflammation in occupational COPD may differs from COPD in tobacco smokers. Additionally cardiotoxicity of industrial chemicals influence heart failure features. Despite this biological plausibility, heart failure and occupational COPD comorbidity is not studied enough. Purpose To reveal predictors of hospitalizations for heart failure decompensation in patients with heart failure and occupational COPD comorbidity. Methods Occupational COPD patients (n=115) were investigated in a prospective cohort observational study. Comparison group – 115 tobacco smokers with COPD. Control group – 115 healthy persons. Controls were selected by propensity score matching, covariates were COPD duration, age and gender. Then COPD groups were stratified according to heart failure. Working conditions, echocardiography, spirometry, pulsoxymetry, 6-mitute walking test were done. Molecular markers of tissue damage – chemokine ligand 18 (CCL 18), lactate dehydrogenase, cardiac troponin T, N-terminal pro-B-type natriuretic peptide (NT pro-BNP), protein S100 beta, von Willebrand factor were measured in serum by ELISA. Follow up after initial assessment was 12 month. Predictors were determined by Cox proportional hazards regression with ROC analysis. Results Heart failure rate in occupational COPD patients were higher – 54.8% versus 36.5% in tobacco smokers with COPD, p<0.05. Heart failure with preserved ejection fraction was predominant – 40.9%. Prevalence of biventricular heart failure was 38.3%, isolated right heart failure – 13%, left heart failure – 2.6%. Cumulative hospitalization rate in occupational COPD with heart failure group was higher than in comparison group, 17.5% and 9.5% respectively, p=0.01. In Cox proportional hazards regression model predictors of hospitalizations for heart failure decompensation during 12 months in this group were length of service (HR 1.22, 95% CI: 1.03–2.5), aromatic hydrocarbons concentration at workplaces air (HR 1.4, 95% CI: 1.15–1.96), serum protein S100 beta (HR 1.10, 95% CI: 1.02–1.87), SaO2 (HR 1.2, 95% CI: 1.06–2.13). Area under the ROC curve was 0.82. Conclusion Length of service, aromatic hydrocarbons concentration at workplaces air, serum protein S100 beta, SaO2 are considered to be independent risk factors of heart failure decompensation required hospitalization in patients with heart failure and occupational COPD comorbidity.

UNSTRUCTURED Objective The aim of this study was to evaluate the effectiveness of home telemonitoring in reducing healthcare usage and costs in patients with heart failure or chronic obstructive pulmonary disease (COPD). Design The study was a retrospective observational study with a pre-post research design and a follow-up duration of up to 3 years, based on hospital data collected in the period 2012-2016. Setting Data was collected at the Slingeland Hospital in Doetinchem, The Netherlands. Participants In 2012 the Slingeland Hospital in The Netherlands started a telemonitoring program for patients with COPD or heart failure as part of their usual care. Patients were eligible for the telemonitoring program if they were in an advanced disease stage (New York Heart Association (NYHA) functional class 3 or 4; COPD gold stage 3 or 4), received treatment for their condition by a cardiologist or pulmonary specialist at the Slingeland Hospital, were proficient in Dutch and capable of providing informed consent. Exclusion criteria were absence of the cognitive, physical or logistical ability required to fully participate in the program. Hundred seventy-seven patients with heart failure and 83 patients with COPD enrolled the program between 2012 and 2016. Intervention Using a touchscreen, participants with heart failure recorded their weight (daily), blood pressure and heart rate (once a week) through connected instruments, and completed a questionnaire about their symptoms (once a week). Symptoms in patients with COPD were monitored via the Clinical COPD Questionnaire (CCQ), which participants were asked to complete twice per week. All home registrations were sent via a telemonitoring application (cVitals, FocusCura, Driebergen-Rijssenburg) on the iPad to a medical service center were a trained nurse monitored the data and contacted the patient by video chat or a specialised nurse in the hospital in case of abnormal results, such as deviations from a preset threshold or alterations in symptom score. Outcome measures The primary outcome was the number of hospitalisations; the secondary outcomes were total number of hospitalisation days and healthcare costs during the follow-up period. Generalised Estimating Equations were applied to account for repeated measurements, adjusting for sex, age and length of follow-up. Results In heart failure patients (N=177), after initiation of home telemonitoring both the number of hospitalisations and the total number of hospitalisation days significantly decreased (incidence rate ratio of 0.35 (95% CI: 0.26-0.48) and 0.35 (95% CI: 0.24-0.51), respectively), as did the total healthcare costs (exp(B) = 0.11 (95% CI: 0.08-0.17)), all p < 0.001. In COPD patients (N=83) neither the number of hospitalisations nor the number of hospitalisation days changed compared to the pre-intervention period. However, the average healthcare costs were about 54% lower in COPD patients after the start of the home telemonitoring intervention (exp(B) = 0.46, 95% CI 0.25-0.84, p = 0.011). Conclusion Integrated telemonitoring significantly reduced the number of hospital admissions and days spent in hospital in patients with heart failure, but not in patients with COPD. Importantly, in both patients with heart failure and COPD the intervention substantially reduced the total healthcare costs.
