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.

Background: Some 20% of patients with stable Chronic Obstructive Pulmonary Disease (COPD) might have heart failure (HF). HF contribution to acute exacerbations of COPD (AECOPD) presenting to the emergency department (ED) is not well established. Aims: To assess (1) the HF incidence in patients presenting to the ED with AECOPD; (2) the concordance between ED and respiratory ward (RW) diagnosis; (3) the factors associated with risk of death after hospital discharge. Methods: Retrospective chart review of 119 COPD patients presenting to ED for acute exacerbation of respiratory symptoms and then admitted to RW where a final diagnosis of AECOPD, AECOPD and HF and AECOPD and OD (other diagnosis), was obtained. ED and RW diagnosis were then compared. Factors affecting survival at follow-up were investigated. Results: At RW, 40.3% of cases were diagnosed of AECOPD, 40.3% of AECOPD and HF and 19.4% of AECOPD and OD, with ED diagnosis coinciding with RW’s in 67%, 23%, and 57% of cases respectively. At RW, 60% of patients in GOLD1 had HF, of which 43% were diagnosed at ED, while 40% in GOLD4 had HF that was never diagnosed at ED. Lack of inclusion in a COPD care program, HF, and early readmission for AECOPD were associated with mortality. Conclusions: HF is highly prevalent and difficult to diagnose in patients in all GOLD stages presenting to the ED with severe AECOPD, and along with lack of inclusion in a COPD care program, confers a high risk for mortality.

Accelerated lung function decline has been associated with increased risk of cardiovascular disease (CVD) in a general population, but little is known about this association in chronic obstructive pulmonary disease (COPD). We investigated the association between accelerated lung function decline and CVD outcomes and mortality in a primary care COPD population.COPD patients without a history of CVD were identified in the Clinical Practice Research Datalink (CPRD-GOLD) primary care dataset (n=36 282). Accelerated FEV1 decline was defined using the fastest quartile of the COPD population's decline. Cox regression assessed the association between baseline accelerated FEV1 decline and a composite CVD outcome over follow-up (myocardial infarction, ischaemic stroke, heart failure, atrial fibrillation, coronary artery disease, and CVD mortality). The model was adjusted for age, gender, smoking status, BMI, history of asthma, hypertension, diabetes, statin use, mMRC dyspnoea, exacerbation frequency, and baseline FEV1 percent predicted.6110 (16.8%) COPD patients had a CVD event during follow-up; median length of follow-up was 3.6 years [IQR 1.7–6.1]). Median rate of FEV1 decline was –19.4 mL·year−1 (IQR, –40.5 to 1.9); 9095 (25%) patients had accelerated FEV1 decline (>–40.5 mL·year−1), 27 287 (75%) did not (≤ –40.5 mL·year−1). Risk of CVD and mortality was similar between patients with and without accelerated FEV1 decline (HRadj 0.98 [95%CI, 0.90–1.06]). Corresponding risk estimates were 0.99 (95%CI 0.83–1.20) for heart failure, 0.89 (95%CI 0.70–1.12) for myocardial infarction, 1.01 (95%CI 0.82–1.23) for stroke, 0.97 (95%CI 0.81–1.15) for atrial fibrillation, 1.02 (95%CI 0.87–1.19) for coronary artery disease, and 0.94 (95%CI 0.71–1.25) for CVD mortality. Rather, risk of CVD was associated with mMRC score ≥2 and ≥2 exacerbations in the year prior.CVD outcomes and mortality were associated with exacerbation frequency and severity and increased mMRC dyspnoea but not with accelerated FEV1 decline.
