The sustained effects of extending cardiac rehabilitation with a six-month telemonitoring and telecoaching programme on fitness, quality of life, cardiovascular risk factors and care utilisation in CAD patients: The TeleCaRe study

Introduction The aim of this study was to assess the acute and sustained effects of a six-month heart-rate-based telerehabilitation programme, following the completion of cardiac rehabilitation (CR), on peak oxygen uptake (peakVO2), quality of life (QoL), cardiovascular risk factors and care utilisation in patients with coronary artery disease (CAD). Methods A total of 122 patients with CAD were randomised, after the completion of CR, to an intervention group with six months of telemonitoring and telecoaching (TELE) or a control group with a traditional six-month follow-up programme with monthly calls (CON). The primary outcome was peakVO2 at 12 months, to assess the sustained effects of TELE. The secondary outcomes included QoL, cardiovascular risk factors (lipid spectrum), major adverse cardiovascular events (MACE) and habitual physical activity. Results PeakVO2 increased significantly from baseline to 12 months in TELE (+2.5 mL·kg−1min−1 (95% CI 1.5–3.2)) and CON (+1.9 mL·kg−1min−1 (95% CI 1.0–2.5)), and did not differ between groups (P = 0.28). Similarly, QoL (P = 0.31), total cholesterol (P = 0.45), MACE (P = 0.86) did not differ between groups and in time. Discussion Extending CR with a heart-rate-based telerehabilitation programme did not yield additional sustainable health benefits compared with regular care with monthly telephone calls. These observations highlight that both telerehabilitation and regular care with monthly telephone calls may prevent the typically observed reductions in peakVO2 following the completion of a CR programme.Trial registration: Dutch Trial Register NL4140 (registered 6 December 2014)
