No favourable effect on mortality was observed with STS HM .
Similar reductions were observed in all-cause hospitalisations for TM interventions , whereas STS interventions had no major effect .
STS HM was dominated by usual care .
Similar results were observed in scenario analyses performed using higher costs of usual care , higher costs of STS HH and lower costs of TM during office hours .
As a result , the economic model developed scenarios for different RM classifications and their costs were estimated using bottom-up costing methods .
Despite wide variation in usual care and RM strategies , cost-effectiveness analyses suggest that TM during office hours was an optimal strategy ( in most costing scenarios ) .
However , clarity was lacking among descriptions of the components of RM packages and usual care and there was a lack of robust estimation of costs .
BACKGROUND Remote monitoring ( RM ) strategies have the potential to deliver specialised care and management to patients with heart failure ( HF ) .
OBJECTIVE To determine the clinical effectiveness and cost-effectiveness of home telemonitoring ( TM ) or structured telephone support ( STS ) strategies compared with usual care for adult patients who have been recently discharged ( within 28 days ) from acute care after a recent exacerbation of HF .
The review included r and omised controlled trials ( RCTs ) or observational cohort studies with a contemporaneous control group that included the following RM interventions : ( 1 ) TM ( including cardiovascular implanted monitoring devices ) with medical support provided during office hours or 24/7 ; ( 2 ) STS programmes delivered by human-to-human contact ( HH ) or human-to-machine interface ( HM ) .
Changes in Brain Natriuretic Peptide and Norepinephrine Over Time and Mortality and Morbidity in the Valsartan Heart Failure Trial (Val-HeFT)
Background —Neurohormones are considered markers of heart failure progression . We examined whether changes in brain natriuretic peptide ( BNP ) and norepinephrine ( NE ) over time are associated with corresponding changes in mortality and morbidity in the Valsartan Heart Failure Trial . Methods and Results —Plasma BNP and NE were measured before r and omization and during follow-up in ≈4300 patients in the Valsartan Heart Failure Trial . The relation between baseline BNP and NE and all-cause mortality and first morbid event ( M&M ) was analyzed in subgroups , with values above and below the median , and by quartiles . The change and percent change from baseline to 4 and 12 months in BNP and NE were also analyzed by quartiles for subsequent M&M. Risk ratios for M&M were calculated using a Cox proportional hazard model . Risk ratio of M&M for patients with baseline BNP or NE above the median was significantly higher than that for patients with values below the median . Baseline BNP and NE in quartiles also showed a quartile-dependent increase in M&M. BNP had a stronger association with M&M than NE . Patients with the greatest percent decrease in BNP and NE from baseline to 4 and 12 months had the lowest whereas patients with greatest percent increase in BNP and NE had the highest M&M. Conclusions —Not only are plasma BNP and NE important predictors of heart failure M&M , but changes in these neurohormones over time are associated with corresponding changes in M&M. These data further reinforce their role as significant surrogate markers in HF and underscore the importance of including their measurement in HF trials
