Evaluation of Novel Metrics of Symptom Relief in Acute Heart Failure: The Worst Symptom Score.

ABSTRACT: To characterize a novel "worst"-symptom visual analogue scale (WS-VAS) versus the traditional dyspnea visual analogue scale (DVAS) in an acute heart failure (AHF) trial.AHF trials assess symptom relief as a pivotal endpoint with the use of dyspnea scores. However, many AHF patients' worst presenting symptom (WS) may not be dyspnea. We hypothesized that a WS-VAS may reflect clinical improvement better than DVAS in AHF.AHF patients (n?=?232) enrolled in the Renal Optimization Strategies Evaluation in Acute Heart Failure (ROSE-AHF) Trial indicated their WS at enrollment and completed DVAS and WS-VAS at enrollment and 24, 48, and 72 hours. Dyspnea was the WS in 61%, body swelling in 29%, and fatigue in 10% of patients. Clinical characteristics differed by WS. In all patients, DVAS scores were higher (less severe symptoms) than WS-VAS and the change in WS-VAS over 72 hours was greater than the change in DVAS (P?

Project description:BackgroundCongestion is a primary driver of symptoms in patients with acute heart failure, and relief of congestion is a critical goal of therapy. Monitoring of response to therapy through the assessment of daily weights and net fluid loss is the current standard of care, yet the relationship between commonly used markers of decongestion and both patient reported symptom relief and clinical outcomes are unknown.Methods and resultsWe performed a retrospective analysis of the randomized clinical trial, diuretic optimization strategy evaluation in acute heart failure (DOSE-AHF), enrolling patients hospitalized with a diagnosis of acute decompensated heart failure. We assessed the relationship among 3 markers of decongestion at 72 hours-weight loss, net fluid loss, and percent reduction in serum N terminal B-type natriuretic peptide (NT-proBNP) level-and relief of symptoms as defined by the dyspnea visual analog scale area under the curve. We also determined the relationship between each marker of decongestion and 60-day clinical outcomes defined as time to death, first rehospitalization or emergency department visit. Mean age was 66 years, mean ejection fraction was 35%, and 27% had ejection fraction ≥50%. Of the 3 measures of decongestion assessed, only percent reduction in NT-proBNP was significantly associated with symptom relief (r=0.13; P=0.04). There was no correlation between either weight loss or net fluid loss and symptom relief, (r=0.04; P=0.54 and r=0.07; P=0.27, respectively). Favorable changes in each of the 3 markers of decongestion were associated with improvement in time to death, rehospitalization, or emergency department visit at 60 days (weight: hazard ratio, 0.91; 95% confidence interval, 0.85-0.97 per 4 lbs; weight lost; fluid hazard ratio, 0.94; 95% confidence interval, 0.90-0.99 per 1000 mL fluid loss; NT-proBNP hazard ratio, 0.95; 95% confidence interval, 0.91-0.99 per 10% reduction). These associations were unchanged after multivariable adjustment with the exception that percent reduction in NT-proBNP was no longer a significant predictor (hazard ratio, 0.97; 95% confidence interval, 0.93-1.02). The rates of death, HF hospitalization, or emergency department visit at 60 days for patients with 0, 1, 2, and 3 markers of decongestion (above the median) were 67%, 64%, 46%, and 38%, respectively (log rank P value=0.05).ConclusionsWeight loss, fluid loss, and NT-proBNP reduction at 72 hours are poorly correlated with dyspnea relief. However, favorable improvements in each of the 3 markers were associated with improved clinical outcomes at 60 days. These data suggest the need for ongoing research to understand the relationships among symptom relief, congestion, and outcomes in patients with acute decompensated heart failure.Clinical trial registrationURL: http://www.clinicaltrials.gov.

Project description:Rationale & objectiveQuality of life in chronic kidney disease (CKD) is impaired by a large burden of symptoms including some that overlap with the symptoms of heart failure (HF). We studied a group of individuals with CKD to understand the patterns and trajectories of HF-type symptoms in this setting.Study designProspective cohort study.Setting & participants3,044 participants in the Chronic Renal Insufficiency Cohort (CRIC) without prior diagnosis of HF.PredictorsSociodemographics, medical history, medications, vital signs, laboratory values, echocardiographic and electrocardiographic parameters.OutcomeTrajectory over 5.5 years of a HF-type symptom score (modified Kansas City Cardiomyopathy Questionnaire [KCCQ] Overall Summary Score with a range of 0-100 where<75 reflects clinically significant symptoms).Analytical approachLatent class mixed models were used to model trajectories. Multinomial logistic regression was used to model relationships of predictors with trajectory group membership.ResultsFive trajectories of KCCQ score were identified in the cohort of 3,044 adults, 45% of whom were female, and whose median age was 61 years. Group 1 (41.7%) had a stable high score (minimal symptoms, average score of 96); groups 2 (35.6%) and 3 (15.6%) had stable but lower scores (mild symptoms [average of 81] and clinically significant symptoms [average of 52], respectively). Group 4 (4.9%) had a substantial worsening in symptoms over time (mean 31-point decline), and group 5 (2.2%) had a substantial improvement (mean 33-point increase) in KCCQ score. A majority of group 1 was male, without diabetes or obesity, and this group had higher baseline kidney function. A majority of groups 2 and 3 had diabetes and obesity. A majority of group 4 was male and had substantial proteinuria. Group 5 had the highest proportion of baseline cardiovascular disease (CVD).LimitationsNo validation cohort available, CKD management changes in recent years may alter trajectories, and latent class models depend on the missing at random assumption.ConclusionsDistinct HF-type symptom burden trajectories were identified in the setting of CKD, corresponding to different baseline characteristics. These results highlight the diversity of HF-type symptom experiences in individuals with CKD.
