Objectives. B-type natriuretic peptide (BNP) levels predict prognosis and outcome in heart failure (HF) patients. To evaluate the optimal cut-off level of BNP to predict death, need for hospitalization, and worsening HF, and also to determine the optimal time to apply the chosen cut-off value. Design. In a sub-study from the Use of PeptideS in Tailoring hEart failure Project or UPSTEP study where tailoring treatment of HF by BNP level was evaluated, we assessed the change in percentage between levels of BNP at study start versus a specific week (2, 6, 10, 16, 24, 36, or 48) during the follow-up period. Results. The optimum cut-off percentage levels were obtained using a Cox proportional regression analysis of death, hospitalization, and worsening HF. A decrease in BNP by less than 40% in week 16 compared with study start and/or a BNP > 300 ng/L presented the highest hazard ratio (HR) for a non-responder to reach a combined endpoint (HR: 2.43; 95% confidence interval or CI: 1.61-3.65; p < 0.00003). This definition gave a 78% risk reduction of cardiovascular (CV) mortality (p > 0.0005) and an 89% risk reduction of HF mortality (p > 0.004), and reduced risk of CV and HF hospitalization for the responders. Conclusions. Patients with a decrease in BNP of more than 40% compared with that at study start and/or a BNP level below 300 ng/L at week 16 had a significantly reduced risk of CV and HF mortality and hospitalization

Long-term and real-life incidence of cancer therapy-related cardiovascular toxicity in patients with breast cancer: a Swedish cohort study

BackgroundThe administration of anticancer drugs in females with comorbidity increases the risk for cancer therapy-related cardiovascular toxicity (CTR-CVT), which in turn contributes to cardiovascular disease (CVD). Furthermore, a pathophysiological connection between cancer and cardiovascular disease may exist.ObjectiveTo assess the long-term risks and predictors of CTR-CVT, including clinical hypertension (HT), coronary artery disease (CAD), heart failure (HF), atrial fibrillation (AF), as well as all-cause mortality in women diagnosed with early breast cancer (BC) and eligible for adjuvant chemotherapy in Sweden.MethodsData were extracted from Swedish registers and medical records on 433 women, 18-60 years of age, diagnosed 1998-2002 with lymph node-positive BC, and considered for adjuvant chemotherapy. CTR-CVT was defined as HT, CAD, HF, or AF after the diagnosis of BC. Follow-up was from the date of BC diagnosis until November 30, 2021, or death. Prevalence of CTR-CVT and all-cause mortality were calculated. Hazard ratios (HR) were determined for factors associated with CTR-CVT.ResultsThe median age was 50 (interquartile range (IQR) 32) years. 910 CTR-CVT events were diagnosed in 311 women with a median of 19.3 (IQR 15,3) years follow-up. The proportions of CTR-CVT events were: HT 281 (64%); CAD 198 (46%); HF 206 (47%); and AF 225 (51%). The cumulative incidence of CTR-CVT was 71.8%, and 50% of all 433 patients developed CTR-CVT within 11.7 years of BC diagnosis (standard deviation (SD) 0.57, 95% confidence interval (CI) 10.6-12.9). Age was a risk factor for CTR-CVT. Anthracycline increased the risk for HF (p=0,001; HR 2,0; 95%CI 1,4-2,8), CAD (p= 0,002; HR 1,7; 95% CI 1,2-2,4), and AF (p=0,013; HR 1,5; 95% CI 1,0-2,0). At the end of the 24-year study period, 227 of the 433 women were alive, and the total cumulative mortality was 47,6%.ConclusionThe prevalence of CTR-CVT and all-cause mortality is high after BC diagnosis and treatment, particularly in older patients and those receiving anthracyclines. These findings and the onset of CTR-CVT support cardio-oncology guidelines recommending initial risk stratification and cardiovascular monitoring during treatment, followed by long-term annual screening for cardiovascular risk factors and CTR-CVT among BC survivors

Effect of B-type natriuretic peptide-guided treatment of chronic heart failure on total mortality and hospitalization: an individual patient meta-analysis

Aims Natriuretic peptide-guided (NP-guided) treatment of heart failure has been tested against standard clinically guided care in multiple studies, but findings have been limited by study size. We sought to perform an individual patient data meta-analysis to evaluate the effect of NP-guided treatment of heart failure on all-cause mortality. Methods and results Eligible randomized clinical trials were identified from searches of Medline and EMBASE databases and the Cochrane Clinical Trials Register. The primary pre-specified outcome, all-cause mortality was tested using a Cox proportional hazards regression model that included study of origin, age (45%) as covariates. Secondary endpoints included heart failure or cardiovascular hospitalization. Of 11 eligible studies, 9 provided individual patient data and 2 aggregate data. For the primary endpoint individual data from 2000 patients were included, 994 randomized to clinically guided care and 1006 to NP-guided care. All-cause mortality was significantly reduced by NP-guided treatment [hazard ratio = 0.62 (0.45-0.86); P = 0.004] with no heterogeneity between studies or interaction with LVEF. The survival benefit from NP-guided therapy was seen in younger (<75 years) patients [0.62 (0.45-0.85); P = 0.004] but not older (≥75 years) patients [0.98 (0.75-1.27); P = 0.96]. Hospitalization due to heart failure [0.80 (0.67-0.94); P = 0.009] or cardiovascular disease [0.82 (0.67-0.99); P = 0.048] was significantly lower in NP-guided patients with no heterogeneity between studies and no interaction with age or LVEF. Conclusion Natriuretic peptide-guided treatment of heart failure reduces all-cause mortality in patients aged <75 years and overall reduces heart failure and cardiovascular hospitalizatio

B-type natriuretic peptide-guided therapy for heart failure (HF):a systematic review and meta-analysis of individual participant data (IPD) and aggregate data

Abstract Background We estimated the effectiveness of serial B-type natriuretic peptide (BNP) blood testing to guide up-titration of medication compared with symptom-guided up-titration of medication in patients with heart failure (HF). Methods Systematic review and meta-analysis of randomised controlled trials (RCTs). We searched: MEDLINE (Ovid) 1950 to 9/06/2016; Embase (Ovid), 1980 to 2016 week 23; the Cochrane Library; ISI Web of Science (Citations Index and Conference Proceedings). The primary outcome was all-cause mortality; secondary outcomes were death related to HF, cardiovascular death, all-cause hospital admission, hospital admission for HF, adverse events, and quality of life. IPD were sought from all RCTs identified. Random-effects meta-analyses (two-stage) were used to estimate hazard ratios (HR) and confidence intervals (CIs) across RCTs, including HR estimates from published reports of studies that did not provide IPD. We estimated treatment-by-covariate interactions for age, gender, New York Heart Association (NYHA) class, HF type; diabetes status and baseline BNP subgroups. Dichotomous outcomes were analysed using random-effects odds ratio (OR) with 95% CI. Results We identified 14 eligible RCTs, five providing IPD. BNP-guided therapy reduced the hazard of hospital admission for HF by 19% (13 RCTs, HR 0.81, 95% CI 0.68 to 0.98) but not all-cause mortality (13 RCTs; HR 0.87, 95% CI 0.75 to 1.01) or cardiovascular mortality (5 RCTs; OR 0.88, 95% CI 0.67 to 1.16). For all-cause mortality, there was a significant interaction between treatment strategy and age (p = 0.034, 11 RCTs; HR 0.70, 95% CI 0.53–0.92, patients < 75 years old and HR 1.07, 95% CI 0.84–1.37, patients ≥ 75 years old); ejection fraction (p = 0.026, 11 RCTs; HR 0.84, 95% CI 0.71–0.99, patients with heart failure with reduced ejection fraction (HFrEF); and HR 1.33, 95% CI 0.83–2.11, patients with heart failure with preserved ejection fraction (HFpEF)). Adverse events were significantly more frequent with BNP-guided therapy vs. symptom-guided therapy (5 RCTs; OR 1.29, 95% CI 1.04 to 1.60). Conclusion BNP-guided therapy did not reduce mortality but reduced HF hospitalisation. The overall quality of the evidence varied from low to very low. The relevance of these findings to unselected patients, particularly those managed by community generalists, are unclear. Systematic review registration PROSPERO CRD4201300533

Heart failure : biomarker effect and influence on quality of life

Background and aims: Heart failure (HF) is a life threatening condition and optimal handling is necessary to reduce risk of therapy failure. The aims of this thesis were: (Paper I) to examine whether BNP (B-type natriuretic peptide)-guided HF treatment improves morbidity and mortality when compared with HF therapy implemented by a treating physician at sites experienced in managing patients with HF according to guidelines; (Paper II) to investigate how to define a responder regarding optimal cut-off level of BNP to predict death, need for hospitalisation, and worsening HF and to determine the optimal time to apply the chosen cut-off value; (Paper III) to evaluate how Health-Related Quality of Life (HR-QoL) is influenced by natriuretic peptide guiding and to study how HR-QoL is affected in responders compared to non-responders; (Paper IV) to evaluate the impact of patient age on clinical outcomes, and to evaluate the impact of duration of the HF disease on outcomes and the impact of age and HF duration on BNP concentration. Methods: A randomized, parallel group, multi-centre study was undertaken on 279 patients with HF and who had experienced an episode of worsening HF with increased BNP concentration. The control group (n=132) was treated according to HF guidelines and in the BNP-guided group (n=147) the HF treatment algorithm goal was to reduce BNP concentration to &lt; 150 ng/L in patients &lt; 75 years and &lt;300 ng/L in patients &gt; 75 years (Paper I), and to define the optimal percentage decrease in BNP and at what point during the follow-up to apply the definition (Paper II). To compare the BNP-guided group with the conventional HF treated group (Paper I), and responders and non-responders (Paper II) regarding HR-QoL measured with Short Form 36 (SF-36) at study start and at study end (Paper III) and to evaluate if age or HF duration influenced the HF outcomes and the influence of BNP on age and HF duration (Paper IV). Results: The primary outcome (mortality, hospitalisation and worsening HF) was not improved by BNP-guided HF treatment compared to conventional HF treatment or in any of the secondary outcome variables (Paper I). Applying a BNP decrease of at least 40 percent in week 16 (compared to study start) and/or a BNP&lt;300 ng/L demonstrated the best risk reduction for cardiovascular mortality, by 78 percent and 89 percent respectively for HF mortality (Paper II). The HR-QoL improved in four domains in the BNP-guided group and in the control group in six of eight domains; however there were no significant differences between the groups (Paper III). For responders the within group analysis showed improvement in four domains compared to the non-responders that improved in one domain; however there were no significant differences between the two groups. There were improvements in HR-QoL in all four groups (Paper III). Age did not influence outcome but HF duration did. HF duration was divided into three groups: HF duration less than 1 year (group 1), 1-5 years (group 2) and &gt;5 years (group 3). A 1.65-fold increased risk could be demonstrated in those with HF duration of more than five years compared to patients with short HF duration. The BNP concentration was increased with increased age, and there was a better response regarding BNP decrease in NP-guiding in patients with short HF duration, independent of age (Paper IV). Conclusions: There were no significant differences between BNP-guided HF treatment group and the group with conventional HF treatment as regards mortality, hospitalisation or HR-QoL. The responders to HF treatment showed a significantly better outcome in mortality and hospitalisation compared to non-responders but no significant differences in HR-QoL. The duration of HF might be an important factor to consider in HF treatment by BNP-guiding in the future

Sodium‐glucose cotransporter 2 inhibitors are associated with reduced risk of mortality and readmissions in heart failure

Abstract Aims Compelling evidence from randomized trials has shown that sodium‐glucose cotransporter 2 inhibitors (SGLT2is) are effective in heart failure (HF) across the spectrum of left ventricular ejection fractions. However, there are very few studies with real‐world data. Methods and results A retrospective cohort analysis was performed based on patient‐level data from the Swedish Heart Failure Registry (SwedeHF) linked with three other national registers. Patients included had an index registration between 3 September 2013 and 31 December 2020 in SwedeHF and were on treatment with guideline‐recommended therapy without or with SGLT2i 3 months before or 6 months after their index registration. Endpoints were mortality or readmissions. Association between the use of SGLT2i and endpoints was studied using adjusted Cox models. In the overall cohort, 796/22 405 patients were included with/without SGLT2i. In patients with SGLT2i, 93.5% had diabetes mellitus. In the overall cohort, SGLT2i was statistically significantly associated with all‐cause mortality {hazard ratio [HR]: 0.61 [95% confidence interval (CI) 0.48–0.79], P < 0.0001}, cardiovascular mortality [HR: 0.29 (95% CI 0.17–0.50), P < 0.0001], cardiovascular mortality or HF readmission [HR: 0.89 (95% CI 0.80–1.00), P = 0.046], and all‐cause readmissions [HR: 0.90 (95% CI 0.81–0.99), P = 0.038]. Similar results were obtained for the diabetes cohort. However, no association with cause‐specific readmissions was observed. Conclusions This nationwide real‐world study indicates that patients with HF, in which majority coexisted with diabetes mellitus, who received SGLT2i were statistically significantly associated with lower risk for all‐cause mortality, cardiovascular mortality, cardiovascular mortality or HF readmissions, and all‐cause readmissions, in line with the randomized trials assessing SGLT2i

The Effect of Internet-Delivered Cognitive Behavioral Therapy Versus Psychoeducation Only on Psychological Distress in Patients With Noncardiac Chest Pain : Randomized Controlled Trial

Background: Patients with recurrent episodes of noncardiac chest pain (NCCP) experience cardiac anxiety as they misinterpret the pain to be cardiac related and avoid physical activity that they think could threaten their lives. Psychological interventions, such as internet-delivered cognitive behavioral therapy (iCBT), targeting anxiety can be a feasible solution by supporting patients to learn how to perceive and handle their chest pain. Objective: This study aims to evaluate the effects of a nurse-led iCBT program on cardiac anxiety and other patient-reported outcomes in patients with NCCP. Methods: Patients with at least two health care consultations because of NCCP during the past 6 months, and who were experiencing cardiac anxiety (Cardiac Anxiety Questionnaire score &amp;gt;= 24), were randomized into 5 weeks of iCBT (n=54) or psychoeducation (n=55). Patients were aged 54 (SD 17) years versus 57 (SD 16) years and were mainly women (32/54, 59% vs 35/55, 64%). The iCBT program comprised psychoeducation, mindfulness, and exposure to physical activity, with weekly homework assignments. The primary outcome was cardiac anxiety. The secondary outcomes were fear of bodily sensations, depressive symptoms, health-related quality of life, and chest pain frequency. Intention-to-treat analysis was applied, and the patients were followed up for 3 months. Mixed model analysis was used to determine between-group differences in primary and secondary outcomes. Results: No significant differences were found between the iCBT and psychoeducation groups regarding cardiac anxiety or any of the secondary outcomes in terms of the interaction effect of time and group over the 3-month follow-up. iCBT demonstrated a small effect size on cardiac anxiety (Cohen d=0.31). In the iCBT group, 36% (16/44) of patients reported a positive reliable change score (&amp;gt;= 11 points on the Cardiac Anxiety Questionnaire), and thus an improvement in cardiac anxiety, compared with 27% of (13/48) patients in the psychoeducation group. Within-group analysis showed further significant improvement in cardiac anxiety (P=.04) at the 3-month follow-up compared with the 5-week follow-up in the iCBT group but not in the psychoeducation group. Conclusions: iCBT was not superior to psychoeducation in decreasing cardiac anxiety in patients with NCCP. However, iCBT tends to have better long-term effects on psychological distress, including cardiac anxiety, health-related quality of life, and NCCP frequency than psychoeducation. The effects need to be followed up to draw more reliable conclusions.Funding Agencies|Kamprad Family Foundation [ISV-2018-00033]</p

Can BNP-guided therapy improve health-related quality of life, and do responders to BNP-guided heart failure treatment have improved health-related quality of life? : Results from the UPSTEP study

Background: To investigate whether B-type natriuretic peptide (NP)-guided treatment of heart failure (HF) patients improved their health related quality of life (Hr-QoL) compared to routine HF treatment, and whether changes in Hr-QoL differed depending on whether the patient was a responder to NP-guided therapy or not. Methods: A secondary analysis of the UPSTEP-study, a Scandinavian multicentre study using a prospective, randomized, open, blinded evaluation design on patients with HF with New York Heart Association (NYHA) class II-IV. NP-guiding was aimed to reduce BNP &lt; 150 ng/L if &lt; 75 years or BNP &lt; 300 ng/L if &gt; 75 years. A responder was defined as a patient with a BNP &lt; 300 ng/L and/or a decrease in BNP of at least 40 % in week 16 compared to study start. Short form-36 (SF-36) was used to measure Hr-QoL. At the study start, 258 patients presented evaluable SF-36 questionnaires, 131 in the BNP group and 127 in the control group. At the study end 100 patients in the NP-guided group and 98 in the control group, presenting data from both the study start and the study end. Results: There were no significant differences in Hr-QoL between NP-guided HF treatment and control group; however significant improvements could be seen in four of the eight domains in the NP-guided group, whereas in the control group improvements could be seen in six of the domains. Among the responders improvements could be noted in four domains whereas in the non-responders improvements could be seen in only one domain evaluating within group changes. Conclusions: Improved Hr-QoL could be demonstrated in several of the domains in both the NP-guided and the control group. In the responder group within group analyses showed more increased Hr-QoL compared to the non-responder group. However, all groups demonstrated increase in Hr-QoL

At the study end 100 patients in the NP-guided group and 98 in the control group, presenting data from both the study start and the study end. Results: There were no significant differences in Hr-QoL between NP-guided HF treatment and control group; however significant improvements could be seen in four of the eight domains in the NP-guided group, whereas in the control group improvements could be seen in six of the domains. Among the responders improvements could be noted in four domains whereas in the non-responders improvements could be seen in only one domain evaluating within group changes. Conclusions: Improved Hr-QoL could be demonstrated in several of the domains in both the NP-guided and the control group. In the responder group within group analyses showed more increased Hr-QoL compared to the non-responder group. However, all groups demonstrated increase in Hr-QoL
