Abstract Background Cardiac rehabilitation (CR) is a comprehensive disease management program highly recommended by heart failure (HF) guidelines. However, the prognostic effects of outpatient CR are inconsistent among recent meta-analyses which enrolled mainly younger HF with reduced ejection fraction (HFrEF). With an aging population, an increased importance of CR has been put on patients with HF with preserved ejection fraction (HFpEF). Purpose This study aimed to examine the prognostic effects of regularly undergoing CR for 6 months after discharge analysing nationwide cohort data including older population with HFrEF and HFpEF. Methods We analysed 2876 patients who hospitalised for acute HF or worsening chronic HF and capable of walking at discharge in the multicentre prospective cohort study. Frequency of outpatient CR participation of each patient was collected using medical records. We assessed CR frequency within 6 months of discharge since most collaborating hospitals conducted final follow-up examinations at 6 months. The CR group was defined as patients who underwent outpatient CR once or more per week for 6 months after discharge. The main study endpoint was a composite of all-cause mortality and HF rehospitalisation during a 2-year follow-up. We performed a propensity score-matched analysis to compare survival rates between the CR and non-CR groups. Propensity scores for each patient were produced by a logistic regression analysis with the CR group as the dependent variable and 33 potential confounders as independent variables. To evaluate events beyond 6 months, we also conducted landmark analyses at 6 months. Results Of the 2876 enrolled patients, 313 underwent CR for 6 months. After propensity score matching using confounding factors, 626 patients (313 pairs) were included in the survival analysis (median age: 74 years, men: 59.6%, median left ventricular ejection fraction [LVEF]: 42%). During 1006.1 person-years of follow-up, 137 patients were rehospitalised due to HF exacerbation, and 50 patients died in the matched cohort. In Cox proportional hazards model (Figure 1), CR was associated with a reduced risk of composite outcomes (hazard ratio [HR] 0.66; 95% confidence interval [CI] 0.48–0.91), all-cause mortality (HR 0.53; 95% CI 0.30–0.95), and HF rehospitalisation (HR 0.66; 95% CI 0.47–0.92). A subgroup analysis showed similar CR effects in patients with HFpEF (LVEF ≥50%) and HFrEF (LVEF <40%). However, in a landmark analysis, CR did not reduce the adverse outcomes beyond 6 months after discharge (Figure 2). Conclusions The findings of this study demonstrate the needs that CR should become a standard treatment for HF regardless of HF type and the necessity of periodical follow-up after completing CR program to maintain its prognostic effects.

Abstract Background and Aims Current guidelines on the management of heart failure (HF) recommend control of blood pressure (BP) in elderly patients. However, the exact treatment goals in this vulnerable population are unclear. Thus, our population-based prospective cohort study aimed to assess whether BP values <140/90 mmHg are associated with a decreased risk of cardiovascular (CV) death and all-cause mortality in HF patients ≥70 years. Method The study included participants of the Berlin Initiative Study (BIS), all ≥70 years, who were treated with antihypertensive drugs and had a diagnosis of HF (ICD-10 codes: I11.0, I13.0, I13.2, I50.x) at baseline. The study period was from 2009 to 2017. Demographics, lifestyle factors, medications, and comorbidities were assessed in face-to-face interviews and from linked administrative healthcare data. Outcomes were adjudicated using death certificates and hospital discharge notes. Cox proportional hazards models yielded crude and adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) of CV death and all-cause mortality associated with normalized BP (systolic BP <140 mmHg and diastolic BP <90 mmHg) compared with non-normalized BP (systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg) in patients with HF. In sensitivity analyses we restricted to high-risk HF patients (≥80 years or with previous CV events). We also repeated the analyses in patients without HF to assess a potential effect modification. Results Among 1623 BIS participants treated with antihypertensive drugs at baseline, 544 (33.5%) had a diagnosis of HF. Of those, 255 (46.9%) showed normalized BP and 289 (53.1%) had non-normalized values. Mean age (standard deviation [SD]) was 82.8 (6.8) years (45.4% female). Selected patient characteristics are shown in the Table. Median (interquartile range) duration of follow-up was 6.7 (4.1-7.3) years. Compared with non-normalized BP, normalized BP was associated with a numerically increased risk of CV death (HR, 1.40; 95% CI, 0.90-2.17) and all-cause mortality (HR, 1.28; 95% CI, 0.96-1.71) in patients with HF. The associations were more pronounced or reached statistical significance when restricting to HF patients ≥80 years (CV death: HR, 1.54; 95% CI, 0.94-2.53 / all-cause mortality: HR, 1.56; 95% CI, 1.11-2.18) or HF patients with previous CV events (CV death: HR, 1.65; 95% CI, 0.83-3.29 / all-cause mortality: HR, 1.33; 95% CI, 0.85-2.07) (Figure). The effect estimates in patients without HF were comparable to those with HF (CV death: HR, 1.18; 95% CI, 0.78-1.78; p for interaction, 0.695 / all-cause mortality: HR, 1.20; 95% CI, 0.93-1.54; p for interaction, 0.604). Conclusion Our study suggests that normalized BP does not decrease the risk of CV death or all-cause mortality in elderly patients with HF and it could even increase the risk especially in high-risk subgroups. Thus, individualized benefit-risk assessment is required for the pharmacotherapy of HF in this vulnerable population.

AbstractObjectiveProspective data on the associations between vitamin D intake and risk of CVD and all-cause mortality are limited and inconclusive. The aim of the present study was to investigate the associations between vitamin D intake and CVD risk and all-cause mortality in the Caerphilly Prospective Cohort Study.DesignThe associations of vitamin D intake with CVD risk markers were examined cross-sectionally at baseline and longitudinally at 5-year, 10-year and >20-year follow-ups. In addition, the predictive value of vitamin D intake for CVD events and all-cause mortality after >20 years of follow-up was examined. Logistic regression and general linear regression were used for data analysis.SettingParticipants in the UK.SubjectsMen (n452) who were free from CVD and type 2 diabetes at recruitment.ResultsHigher vitamin D intake was associated with increased HDL cholesterol (P=0·003) and pulse pressure (P=0·04) and decreased total cholesterol:HDL cholesterol (P=0·008) cross-sectionally at baseline, but the associations were lost during follow-up. Furthermore, higher vitamin D intake was associated with decreased concentration of plasma TAG at baseline (P=0·01) and at the 5-year (P=0·01), but not the 10-year examination. After >20 years of follow-up, vitamin D was not associated with stroke (n72), myocardial infarctions (n142), heart failure (n43) or all-cause mortality (n281), but was positively associated with increased diastolic blood pressure (P=0·03).ConclusionsThe study supports associations of higher vitamin D intake with lower fasting plasma TAG and higher diastolic blood pressure.

Surprise Question

ObjectiveThe Surprise Question (SQ) is a prognostic screening tool used to identify patients with limited life expectancy. We assessed the SQ’s performance predicting 1-year mortality among patients in ambulatory heart failure (HF) clinics. We determined that the SQ’s performance changes according to sex and other demographic (age) and clinical characteristics, mainly left ventricular ejection fraction (LVEF) and the New York Heart Association (NYHA) functional classifications.MethodsWe conducted a prospective cohort study in two HF clinics. To assess the performance of the SQ in predicting 1-year mortality, we calculated the sensitivity, specificity, positive and negative likelihood ratios, and the positive and negative predictive values. To illustrate if the results of the SQ changes the probability that a patient dies within 1 year, we created Fagan’s nomograms. We report the results from the overall sample and for subgroups according to sex, age, LVEF and NYHA functional class.ResultsWe observed that the SQ showed a sensitivity of 85% identifying ambulatory patients with HF who are in the last year of life. We determined that the SQ’s performance predicting 1-year mortality was similar among women and men. The SQ performed better for patients aged under 70 years, for patients with reduced or mildly reduced ejection fraction, and for patients NYHA class III/IV.ConclusionsWe consider the tool an easy and fast first step to identify patients with HF who might benefit from an advance care planning discussion or a referral to palliative care due to limited life expectancy.

Abstract Background Obstructive sleep apnoea (OSA) is highly prevalent among patients with heart failure. Accumulating research data suggest that this association is bidirectional. Less is known regarding the long-term impact of OSA and continuous positive airway pressure (CPAP) treatment on incident heart failure. Purpose We addressed the association of severe OSA with development of heart failure, and consequently addressed the impact of efficient CPAP treatment in a sleep clinic cohort. Methods The “Sleep Apnea Patients in Skaraborg (SAPIS)” project was a single center (two sites), open-label, prospective cohort study, conducted in Sweden between 2005 and 2018. All consecutive adults admitted to the Skaraborg Hospital between 2005 and 2011 were registered in a local database, and the follow-up ended in May 2018. Anthropomorphic and clinical characteristics as well as results of the diagnostic cardiorespiratory recordings were documented. Treatment of OSA was based on the clinical routines. OSA was defined as an apnoea-hypopnoea index (AHI) of at least 5 events/hr, and severe OSA consisted of patients with an AHI ≥30 events/hr. Median follow-up for the entire cohort was 8.8 years (interquartile range 7.5–10.1 years). Data regarding incident heart failure were obtained from the medical records and the Swedish Hospital Discharge Register. CPAP use (downloaded reports from the devices) of at least 4 hrs/night was defined as efficient treatment. Results Among 4239 patients with diagnostic sleep recordings, 3185 were free of a known cardiac disease at baseline. Severe OSA was observed among 953 (29.9%). Severe OSA significantly predicted incident heart failure (hazard ratio [HR] 2.42; 95% confidence interval [CI] 1.44–4.06) compared to adults with AHI <30 events/hr, adjusted for age, gender, obesity, hypertension and diabetes mellitus. The adjusted HR for severe OSA was 2.82 (95% CI 1.33–5.99) among inefficiently treated/untreated patients whereas the risk was lower but still meaningful among the individuals who were adherent to CPAP (HR 2.25; 95% CI 0.99–5.15) Conclusion Our results suggest that severe OSA is associated with increased risk for development of heart failure. More than 4 hours of CPAP use per night may be necessary for OSA patients in the primary prevention models.

Abstract Funding Acknowledgements Type of funding sources: None. Background Despite the benefits of exercise training in the secondary prevention of cardiovascular disease, there are conflicting findings for the impact of exercise-based cardiac rehabilitation (CR) on mortality for patients with heart failure (HF). Methods A retrospective cohort study was conducted which utilised a global federated health research network. Patients with a diagnosis of HF were compared between those with and without an electronic medical record of exercise-based CR within 6-months of a HF diagnosis. Patients with HF undergoing exercise-based CR were propensity score matched to HF patients without exercise-based CR by age, sex, race, co-morbidities, medications, and procedures. We ascertained 2-year incidence of all-cause mortality, hospitalisation, stroke, and atrial fibrillation. Results Following propensity score matching, a total of 40,364 patients with HF were identified. Exercise-based CR was associated with 42% lower odds of all-cause mortality (odds ratio 0.58, 95% confidence interval (CI): 0.54-0.62), 26% lower odds of hospitalisation (0.74, 95% CI 0.71-0.77), 37% lower odds of incident stroke (0.63, 95% CI 0.51-0.79), and 53% lower odds of incident atrial fibrillation (0.47, 95% CI 0.4-0.55) compared to matched controls. The beneficial association of exercise-based CR on all-cause mortality was consistent across stratification for sex, older age, included comorbidities, and HF subtype (all P < 0.0001), including patients with HFpEF (0.65, 95% CI 0.60-0.71). Conclusions Exercise-based CR was associated with lower odds of all-cause mortality, hospitalisations, incident stroke and incident atrial fibrillation at 2-years follow-up for patients with HF. The beneficial association of CR and lower mortality was consistent for patients with HFrEF and HFpEF.

ObjectiveAlthough associations between testosterone and cardiovascular (CV) morbidity in women have been proposed, no large prospective study has evaluated potential associations between testosterone and mortality in women. The objective was to determine whether baseline testosterone levels in women are associated with future overall or CV morbidity and mortality.DesignProspective cohort study with a 4.5-year follow-up period.MethodsFrom a representative sample of German primary care practices, 2914 female patients between 18 and 75 years were analyzed for the main outcome measures: CV risk factors, CV diseases, and all-cause mortality.ResultsAt baseline, the study population was aged 57.96±14.37 years with a mean body mass index of 26.71±5.17 kg/m2. No predictive value of total testosterone for incident CV risk factors or CV diseases was observed in logistic regressions. Patients with total testosterone levels in the lowest quintile Q1, however, had a higher risk to die of any cause or to develop a CV event within the follow-up period compared to patients in the collapsed quintiles Q2–Q5 in crude and adjusted Cox regression models (all-cause mortality: Q2–Q5 versus Q1: crude hazard ratios (HR) 0.49, 95% confidence interval (CI) 0.33–0.74; adjusted HR 0.62, 95% CI 0.42–0.939; CV events: Q2–Q5 versus Q1: crude HR 0.54, 95% CI 0.38–0.77; adjusted HR 0.68, 95% CI 0.48–0.97). Kaplan–Meier curves revealed similar data.ConclusionsLow baseline testosterone in women is associated with increased all-cause mortality and incident CV events independent of traditional risk factors.

Background. Proteinuria has been related to all-cause mortality, showing regression or progression. However, few studies have focused on the relationship between proteinuria changes and all-cause mortality. The main purpose of this paper is to examine the associations between proteinuria changes and all-cause mortality in people with diabetes or prediabetes. Methods. Dipstick proteinuria at baseline and a 2-year follow-up were determined in the participants attending the Kailuan prospective cohort study. Participants were then divided into three categories: elevated proteinuria, stable proteinuria, and reduced proteinuria. Four Cox proportional hazard models were built to access the relations of proteinuria changes to all-cause mortality, adjusting for other confounding covariates. Results. A total of 17,878 participants were finally included in this study. There were 1193 deaths after a median follow-up of 6.69 years. After adjusting for major covariates and proteinuria at baseline, mortality risk was significantly associated with elevated proteinuria (hazard ratio (HR): 1.54, 95% confidence interval (CI): 1.33–1.79) and reduced proteinuria (HR: 0.70, 95% CI: 0.55–0.89), compared to those with stable proteinuria. Conclusion. Proteinuria changes were independently associated with mortality risk in either diabetic or prediabetic population.
