Effects of Telemonitoring and Hemodynamic Monitoring on Mortality in Heart Failure: a Systematic Review and Meta-analysis

Purpose of Review To examine the effectiveness of telemonitoring and hemodynamic monitoring devices in reducing mortality rates in heart failure. PubMed and Cochrane Library were searched to 1 May 2017 for randomized controlled trials and real-world studies investigating the effects of telemonitoring or hemodynamic monitoring on mortality in heart failure. Recent Findings Heart failure is associated with increased mortality. Telemonitoring and hemodynamic monitoring have been shown to reduce mortality rates in some studies but not others. Summary Fifty-two and five publications on telemonitoring and hemodynamic monitoring were included. In 23,233 patients (mean age 70 years, mean follow-up 12 ± 10 months), telemonitoring reduced all-cause mortality by 22% (HR = 0.78; 95% confidence interval (CI), 0.74–0.83; P < 0.0001). In 1224 patients (mean age 59 years, mean follow-up 12 ± 6 months), wireless hemodynamic monitoring had no effect on all-cause mortality (HR = 0.87; 95% CI, 0.61–1.25; P > 0.05). Overall, telemonitoring but not hemodynamic monitoring reduced mortality in heart failure.
