PURPOSE: This study aimed to assess the effects of a home-based cardiac telerehabilitation (HBCT) on cardiac hemodynamic and functional responses and health-related quality (HRQOL) of the patients undergoing percutaneous coronary intervention (PCI). MATERIALS AND METHODS: In this randomized controlled clinical trial, single-blinded. One hundred-fifty-five patients (mean age 50.41 +/- 7.3 years, 41 women and 39 men) who underwent PCI were randomized into the two groups of intervention and control. The HBCT program included supervised exercise training, walking, phone calls, and a pedometer for 8 weeks. Hemodynamic changes, including systolic blood pressure (SBP) and diastolic blood pressure (DBP), resting heart rate (HRrest), maximum heart rate (HRmax), ejection fraction (EF), and rate pressure product (RPP), and functional parameters including the distance walked and metabolic equivalents (METS), also HRQOL were measured in all patients before and after the 8-week HBCT program. RESULTS: Our results showed significant reductions in SBPrest (126.82 +/- 9.17 versus 131.27 +/- 10.24; p = 0.044), DBPrest (87.4 +/- 5.39 versus 89.17 +/- 7.33; p = 0.027), HRrest (76.15 +/- 3.01 versus 77.65 +/- 4.16; p = 0.041), HRmax (143.1 +/- 5.24 versus 147.57 +/- 8.63; p = 0.011), and RPP (9.64 +/- 0.81 versus 10.07 +/- 0.99; p = 0.007) and significant elevations in (45.75 +/- 4.31 versus 43.5 +/- 5.21; p = 0.039), distance walked (514.95 +/- 214.5 versus 368.04 +/- 221.43; p = 0.019), Mets (7.41 +/- 0.84 versus 6.89 +/- 1.28; p = 0.018), as well as HRQOL in the MCS (50.62 +/- 10.45 versus 46.25 +/- 7.74; p = 0.037), and HRQOL in the PCS (46.75 +/- 8.73 versus 42.37 +/- 9.99; p = 0.040) in the intervention group compared to the control group. CONCLUSION: An HBCT program consisting of supervised exercise training significantly improved hemodynamic response, exercise performance capacity, and HRQOL in patients following PCI.
